Plumbing Technical Certificate Scheme Handbook & Scheme Standards 

1. Foreword 

This document should be read in conjunction with ‘Providing City & Guilds Qualifications’ which 

details the general requirements for approved centres in offering plumbing awards and which must 

be adhered to, to offer the plumbing scheme. 

Detail that follows is specific to the plumbing technical certificate (6129) scheme. 

Technical Certificates in Plumbing (6129 scheme) are named as below – 

• City & Guilds Level 2 Certificate in Basic Plumbing Studies 

• City & Guilds Level 3 Certificate in Domestic Plumbing Studies 

They have been developed to provide the basic training (in college or centre) for plumbing new 

entrants including those on Apprenticeship Programmes, or other new entrants, the detail 

contained in this handbook must be applied by all centres on a mandatory basis. 

This handbook describes the schemes at Levels Two and Three, being implemented from 2003. 

Appendices A-C detail the technical certificate scheme standards – these are particularly important 

to centres as they detail the scheme requirements against which the assessments have been 

developed and moreover provide a brief to centres on developing training programmes to support 

the scheme. The scheme standards are produced in a systems unit format for ease of programme 

delivery profiled against the NVQ units to demonstrate effective NVQ coverage. 

When referring to ‘technical certificates’ this is a generic term only and centres must use correct 

accredited titles when referring to these qualifications. The name ‘technical certificate’ may be 

used within this document for ease of use when referring to the 6129 scheme. 

2. Introduction 

The Technical Certificate Competences 

The Level 2 and 3 Technical Certificates described in this Handbook cover the competences 

required by the Plumbing NVQ units in the following areas: 

• Practical systems installation, commissioning & maintenance skills – the material and tool 

skills required to measure – cut – bend – join – prefabricate – install the systems materials 

and components, commission and maintain systems within the range of the qualification 

units 

• Underpinning or supporting knowledge – the essential knowledge required to work safely 

in plumbing activities – work with and install systems materials and components – install 

systems in compliance with current legislation and the industry standards for good 

practice 

• The Technical Certificates also cover the knowledge required to work with other people 


Technical Certificates as a source of NVQ evidence 

The Technical Certificates have been designed to provide a basis for the training required to 

support the NVQs in Plumbing, and knowledge and practical assessments undertaken by 

Technical Certificate candidates can contribute to the evidence requirements of the NVQs in 

Plumbing for which candidates will register – where designated by the awarding body. 

The importance of training in current practices 

It is important to candidates that their Technical Certificate programme provides them with training 

in current plumbing practices - with materials, components, and equipment of types that are in 

current use within the industry. 

Centres are therefore required to provide installation facilities which realistically simulate workplace 

conditions, and to ensure that as far as possible candidates carry out practical task assessments in 

a manner that reflects the actual working procedures employed in the workplace. Detailed 

requirements in relation to practical facilities are therefore laid down by the awarding body; these 

requirements must be followed by each centre on a mandatory basis. 


3. The Technical Certificate Scheme 6129 and Plumbing NVQ Scheme 6089 

Qualification Structure 

The relationships between the Plumbing Technical Certificates and the Plumbing NVQs are as 

shown below. 

Candidates will be permitted to carry the results of Technical Certificate knowledge assessments 

and a number of practical assessments forward as evidence to be set against NVQ requirements. 

However all NVQ Candidates must produce evidence from their workplace on a mandatory basis 

(laid down in NVQ scheme documentation) and undertake additional independent assessments 

(for Gas – ACS, Water Regulations, Unvented Domestic Hot Water Storage Systems) 

The same knowledge assessment tests apply for the Technical Certificate and NVQs, with the 

exception of those competences for which independent assessments are undertaken. 

Performance evidence from the Technical Certificate Practical Tasks can contribute to the 

performance evidence requirements of the NVQs (further detail is identified in the Plumbing NVQ 

scheme documentation).

4. The Technical Certificate Standards 

The content of the Technical Certificate units has been mapped to the NVQs on which they are 

based so that the links between the Technical Certificate and the NVQs are readily identifiable. 

However Technical Certificate assessments are ‘freestanding’ and for Technical Certificate 

purposes Centres do not have to concern themselves with any ‘cross mapping’ of outcomes 

against NVQ performance criteria and range.

training programme, under conditions required by the Awarding Body 


NOTE 

• facilities for the training and assessment of candidates on the practical requirements of 

the scheme to be undertaken at appropriate times within the training programme, under 

conditions required by the Awarding Body 

The use of Technical Certificate knowledge and practical assessments as NVQ evidence imposes 

upon Technical Certificate Centres a requirement to apply the same stringent controls and 

conditions to the assessment procedures as are required by the NVQ assessments. 

4.3 Centre Staff Qualifications 

Assessors 

Technical Certificate centres must provide the following in relation to competent staff in order to be 

approved by the Plumbing Awarding Body -

5. Assessment Procedures 

5.1 Knowledge assessments – general requirements 

The Technical Certificates at Levels Two and Three require candidates to undertake knowledge 

assessments which include: 

• Multiple-choice questions – centrally set and locally marked 

• Multiple choice questions – centrally set and centrally marked 

• Assignment on Job Planning requiring short written answers - paper centrally set and locally 

marked 

Candidates should undertake these assessments when they have completed the training in the 

appropriate subject areas to a satisfactory standard – the assessments are not intended to be ‘end 

assessments’ (with the exception of the centrally set, centrally marked papers) 

5.2 Centrally Set and Locally Marked Multiple-Choice Papers 

The Awarding Body will provide for all Technical Certificate/NVQ Assessment Centres three series 

of multiple-choice question papers (Series A – Series B – Series C) 

Each series includes a number of question papers which in total cover all the knowledge 

requirements of all the units and system ranges within the qualifications at Level Two and Three 

(with an exception at Level Three for certain knowledge competences which are covered by 

assignment style short written answer papers) 

Timing of knowledge assessments 

The multiple-choice question assessment and written assessments should be taken by candidates 

at times which suit the individual candidate’s training progress. The Assessor will make a decision 

as to whether individual candidates are at a stage of training, or previous experience in the case of 

mature candidates, which indicates that the candidate has a high potential for success in the 

papers that he or she is to undertake. 

Centres must not ‘accumulate’ the knowledge assessments to offer them as an ‘end assessment’. 

Within that provision: 

1. Candidates may take one or more papers at the same time, up to a limit of 3 separate papers 

2. Different candidates may take different papers according to their individual assessment needs 

at the time 

3. Groups of candidates may take the same paper(s) at the same time, or a range of different 

papers 

The basis of assessment for the range of locally marked plumbing knowledge assessment tests is 

as follows and as detailed in Version 3 of ‘Specific instructions on the conduct, administration and 

marking of centrally set locally marked assessments’ provided to approved centres on CD with 

C&G developed question papers for the plumbing schemes. 


These papers assess the knowledge requirement of the following plumbing qualifications: 

• 6129 Certificate in Basic Plumbing Studies – Level 2 

• 6129 Certificate in Domestic Plumbing Studies – Level 3 

• 6089 Levels 2 & 3 National Vocational Qualification (NVQ) in Plumbing. 

These instructions cover the conduct, administration and marking of the following 6129 Level 2 & 3 

assessment tests (all closed book except for those shown in italics below):

Note: 

Unit 401 is an additional unit that is a mandatory requirement for those candidates completing an 

apprenticeship scheme. As a guide training and assessment of this unit should occur early in the 

delivery programme as the topic primarily supports the apprentice induction process. 


5.3 General introduction 

The instructions given supplement the general requirements laid down for the conduct of 

knowledge based assessments in the document – Providing City & Guilds Qualifications – Edition 

4 October 2004. 

Assessment consists of multiple-choice tests (see the aforementioned list for detail on which 

papers are open or closed book), with the exception of unit 300 which is an underpinning 

knowledge question based assignment. Centres will have particular responsibility with regard to 

the administration and conduct of these examinations as follows: 

5.3.1 Centres are responsible for ensuring that the standard rules with regard to the conduct of 

written examinations are complied with. 

5.3.2 Under current arrangements a separate examination paper is provided for each unit. A CD- 

ROM containing a bank of test papers will be provided, on receipt of a written order on the 

pro forma provided. The CDs will only be issued to centres with 6129/6089 Level 2 and / or 

3 scheme approval. 

5.3.3 Centres will be responsible for marking all assessments and it is the responsibility of the 

centre to conduct examinations according to the rules and procedures detailed by City & 

Guilds. 

5.4 Administration and Security 

All centres must have an Examinations Secretary who is responsible for the security of the CD- 

ROM. Centres may nominate an additional member of staff who will have monitored access to the 

papers and answer keys. This individual could be a plumbing scheme 

• assessor 

• internal verifier 

• co-ordinator. 

The purpose of this second nominated member of staff is to provide additional support to the 

Examinations Secretary, resulting in a simpler examination process. 

If a centre chooses to use a second nominated member of staff, particular attention must be paid 

to the following points: 

• the Examinations Secretary is responsible for the security of the CD-ROM and the printing 

of examination papers 

• the second nominated member of staff must complete and sign the release form (as shown 

at Appendix G of Specific instructions on the conduct, administration and marking of 

centrally set locally marked assessments’) when taking examination papers and/or answer 

keys from the Examinations Secretary. 

• when the second nominated member of staff has signed for the papers, they are 

responsible for their safe keeping and security. All examination papers and answer keys 

that have been signed out must be returned to the Examinations Secretary and signed 

back in on their return. This is to ensure that there is an auditable trail of all occasions 

when examination papers are handed over by the Examinations Secretary 

• while in possession of the examination papers and/or answer keys, the second nominated 

member of staff must deliver them directly to the examination invigilator. They must not 

disclose their contents to any other person, or make any further copies 


5.5 Examination papers 

City & Guilds will issue approved centres with a CD-ROM containing test papers. There will be 

only three active versions of each paper at any time (Versions A, B and C). When a new set of 

assessments (revised versions) becomes available they will be automatically issued to all 

approved centres at each level 2 or 3. It is essential to maintain the integrity and security of the 

tests, secure storage and handling of the papers is most important. The nominated individual (see 

5.4) is responsible for ensuring that the following precautions are taken: 

5.5.1 Papers are printed from the CD-ROM under secure conditions and stored securely until the 

time of the test. An inventory of papers printed and stored is set up and kept up to date, 

when new copies are printed and used papers are destroyed. 

5.5.2 No papers are ever to be printed and handed to candidates except for test purposes. 

5.5.3 The CD-ROM and printed papers are kept under secure conditions at all times in a safe or 

secure cabinet. 

5.5.4 Papers held by an examination invigilator must be kept secure at all times and only be 

issued to candidates for the duration of the examination. All papers must be accounted for 

at the completion of the examination. 

5.5.5 There must be no possibility that any unauthorised person is able to take a copy of an 

examination paper or to obtain or remove any such copy. 

5.5.6 Controlled access to each assessment paper may be provided to scheme assessors and 

internal verifiers, in order that they can prepare for undertaking marking of question papers 

and oral questioning. This access can only be granted by the Examinations Secretary. 

The second nominated person (see 5.4) does not have the authority to do this. 

5.6 The delivery and marking of examinations (closed book tests) 

Invigilation of the testing process is a requirement of the scheme. It is preferable that invigilation 

and subsequent marking of test papers is conducted by a qualified plumbing scheme assessor 

who has / will not be involved in the training or internal verification of the particular unit being 

assessed. This is in order that the marking process may be streamlined and simplified for the 

Candidate. In situations where a non-technical invigilator is being utilised then satisfactory 

arrangements need to be in place to facilitate timely marking of papers, re-sit arrangements and 

any subsequent oral questioning. 

The centre must be able to provide qualified plumbing scheme assessors to mark question papers 

and implement oral questioning arrangements. 

5.7 Conducting the examination 

This element of the guidance note is largely based on the Providing City & Guilds Document – 

Edition 4 (October 2004). Specific points worthy of note are 

• The scheme assessor must confirm the key details of the assessment with the 

Examinations Secretary well in advance of the assessment taking place in order that 

Candidates have suitable time to prepare for the assessment and the papers to undertake 

the assessment can be made ready. 

• The Examinations Secretary must ensure that the different versions of the question papers 

are rotated and a record is kept each time a test is used for a particular candidate. 


• It is then the responsibility of the invigilator / scheme assessor to ensure that the 

examination is conducted under examination conditions including 

- candidates must be seated in such a way that there is no possibility of interference 

or collusion and to conform to City & Guilds written examination requirements 

- any course notes and reference material must be kept out of sight of candidates. 

See exceptions for Level 3 papers in the guidance notes 

- all candidates must have appropriate pens, pencils, etc as listed on the test paper 

and a City & Guilds multiple choice answer sheet MA 

- the answer sheets must have the candidate’s name, date of examination, paper 

number and version number 

- examination regulations include how to complete the answer sheets and must be 

clearly explained by the invigilator. 

At the conclusion of the examination all the question papers and answer sheets must be collected. 

The invigilator must not discuss with any candidates the answers or any other details relating to the 

test prior to marking the test. 

5.8 Marking the examination 

It is preferable that the marking of the examination is conducted by a qualified plumbing scheme 

assessor who has not been involved in the training or will not be involved in the internal verification 

for that particular unit. Ideally this person would be the second nominated member of staff (see 

5.4). It is also preferable that the marking of papers takes place during the particular session so 

that a conclusion to the test is reached and the candidate has immediate feedback as to the 

outcome of the test. 

Each test paper has an associated answer key grid that states the correct answer to all questions: 

a, b, c or d. The answer keys should be kept under the same secure conditions as the question 

papers, but must be stored separately. 

Marking is based on the following 

• Candidates who achieve 80% or more are deemed to have passed the test 

• Candidates who achieve between 70 and 79% should receive feedback (preferably during 

the same examination session) on the questions that were incorrectly completed. That 

feedback should be in the form of a new blank answer grid indicating (by circling with pen) 

the question numbers that have been incorrectly answered. The Candidate should then be 

permitted the opportunity of re-taking those particular questions without reference to the 

answers given in the first attempt. If the candidate 

- then achieves 80% or more the assessment is deemed to have been passed 

- overall score still remains between 70 & 79% then oral questioning can take place. 

That oral questioning must relate to the question in the paper that has been posed 

in terms of re-phrasing the question, a completely new question must not be 

devised by the assessor. If the overall score under oral questioning rises to 80% or 

more then the assessment is deemed to have been passed. If the score following 

oral questioning remains at between 70 & 79% then the assessment is deemed to 

have been failed and a complete new paper will have to be re-taken at a later date. 


• Candidates who achieve 69% or less are deemed to have failed the test and a complete 

new paper will have to be taken at a later date. 

Feedback must be provided to candidates on whether they have been successful in the test within 

a 7 day period, the re-sit of a full paper must not occur within 7 days of the previous paper being 

taken. 

Appendix A & B of ‘Specific instructions on the conduct, administration and marking of centrally set 

locally marked assessments’ contains example recording sheets for centres to record details of 

completion of the test papers. 

5.9 The delivery and marking of examinations (open book tests) 

The procedures for the delivery and marking of open book examination papers are as detailed for 

closed book examinations, with the following additions 

• the invigilator must co-ordinate the use of open book resource materials to support each of 

the tests in a manner that will ensure that the required examination conditions are not 

impaired i.e. laying down a procedure for candidates to gain access to technical 

publications and return those publications for other candidates to use, and the provision of 

suitable number of resource documents commensurate with the number of candidates 

being assessed 

• Level 3 Paper 305 – Domestic Gas Safety Parts 1 & 2 

This paper has been split into two parts due to the number of questions. Each part contains 

60 questions and can be delivered in one session but it is recommended that the 

candidates have a break after taking 305 Part 1. It is recommended that this paper is split 

into a morning and afternoon session. 

Candidates are allowed reference material for both Part 1 and 2 (open book). 

The only reference material allowed is: 

CORGI Essential Gas Safety 

4 th edition (at time of these notes being published) 

Gas Installers Manual Series 

ISBN; 1-902632-00-1 

CORGI Website: www.corgi.com 

• Level 3 Paper 300 - Systems Planning Assignment 

The marking scheme for this assignment is based on the candidate achieving the key 

points for each question as indicated on the model answer sheet provided. Each question is 

worth one mark. 

Refer to Appendix C of ‘Specific instructions on the conduct, administration and marking of 

centrally set locally marked assessments’ for a list of acceptable resource materials that 

can be used during the examination. 

• Additional Unit Paper 401 - Employment rights and responsibilities 

Refer to Appendix D of ‘Specific instructions on the conduct, administration and marking of 

centrally set locally marked assessments’ for a list of acceptable resource materials that 

can be used during the examination. 


5.10 Guidance on oral questioning 

If a candidate has to be assessed / questioned verbally to try and obtain a pass, a qualified 

Plumbing Assessor (preferably not involved in the teaching or internal verification of the particular 

unit being assessed) must conduct oral questioning under controlled conditions with detail of 

responses written down and recorded (See Appendix E of ‘Specific instructions on the conduct, 

administration and marking of centrally set locally marked assessments’ for example recording 

sheet). 

The answers given by the candidate must not be as a result of coaxing by the assessor and must 

truly reflect the candidate knowledge in the area being questioned / assessed. This also ensures 

that if a pass is gained through verbal question assessment the quality and integrity of the award is 

upheld. The response sheet once signed by the Assessor is placed with the answer paper so that 

when the External Verifier visits there is an auditable trail that can be followed and integrity 

maintained. 

When using verbal / oral assessment, Assessors should be mindful of the effect their behaviour 

can have on candidate performance. Questions should be asked in the spirit of gaining information 

rather than pressurising a candidate by creating the atmosphere of a test or making the candidate 

feel inhibited or intimidated by the verbal assessment method. 

Assessors should also take care to ask questions clearly. The following list provides a brief 

overview of phrases typically used in verbal / oral questioning and are provided as a guide to 

Assessors. They are not mandatory and may not be applicable according to the specific unit 

questions that are being verbally assessed: 

Question 

List / name 

State 

Describe briefly 

Outline 

Compare/contrast 

Define 

Explain why 

Sketch 

Required Response 

Give a list rather than sentences as your answer 

Give the relevant facts briefly and to the point 

Give a brief but full account with examples of the procedure, 

term etc. specified in the question 

Briefly give all the essential points 

Point out similarities and differences, advantages and 

disadvantages of the items mentioned in the question 

Give the exact meaning e.g. of a term, principle or 

procedure 

Give the reason for 

Do a freehand drawing 

Assessors are reminded that these guidelines are for assessment use in determining the 

candidate’s knowledge of the area covered by the question. The original test questions are in a 

multiple choice format so Assessors will need to adapt and approach the verbal assessment of the 

question in the most appropriate way. Assessors are reminded that the oral questioning of 

candidates must relate to the original question being posed, as an example it is not appropriate to 

ask an oral question of a different technical nature. 

5.11 Scheme quality assurance 

The centre must implement suitable quality assurance arrangements to ensure the consistent and 

rigorous application of scheme requirements on all occasions that examinations are being 

conducted. The centre must therefore implement documented internal verification procedures 

commensurate with the number of candidates being assessed to ensure - 


• spot-checking of the invigilation process 

• marking of assessment papers – including attendance during marking procedures being 

undertaken 

• effective application of oral questioning techniques by assessors – again including 

attendance during oral questioning sessions. 

A further check and a sampling of examination procedures and processes will be conducted by 

City & Guilds appointed External Verifiers each time during their visits. 

The integrity of the complete examination process is also subject to further “ad hoc” inspections by 

representatives of the Awarding Body. 

5.12 Completion of the locally marked test papers 

A candidate should have satisfactorily completed all of the locally marked assessments before 

entering the GOLA end test at each level. 

Candidates who have been successful can have their grades entered on Form S or via the City & 

Guilds’ Walled Garden. The grade must be entered as P (pass). Form S should be forwarded to 

City & Guilds for results processing. 

The centre must retain all test material for a period of one year after the candidate has completed 

the course. Records must be retained for three years after completion of the award. 

5.13 Copyright and ownership details 

The multiple-choice question papers are the copyright of City & Guilds. The contents of the 

examination papers including the wording of individual questions shall not be disclosed without the 

written authorisation of City & Guilds. Neither may such multiple-choice questions be published or 

used in any other form other than for their intended purpose. 

If a centre wishes to query an examination paper or question they should only do so in writing to 

City & Guilds (see Appendix F of ‘Specific instructions on the conduct, administration and marking 

of centrally set locally marked assessments’) and post to: 

Assessment Manager - Scheme 6129 

Construction and Engineering Sector 

Building Services Team 


London 

EC1A 9DD 

All queries will be logged and investigated and referred to expert examiner/s if necessary. 


5.14 Centrally set and centrally marked (independent assessment tests) 

The technical certificate knowledge assessment arrangements require the application of an 

independent assessment element comprising of two Centrally set and marked papers operated via 

the City & Guilds on-line GOLA system 

• Level Two – a 50 question multiple-choice paper covering a sample of all systems in the Level 

2 range – Cold Water, Domestic Hot Water etc. from the centrally set and locally marked 

papers 

• Level Three – a 50 question multiple-choice paper covering a sample of all systems papers in 

the Level 3 range – Cold Water, Domestic Hot Water etc., from the centrally set and locally 

marked papers 

The Awarding Body will set and mark, and issue results for these papers. 

The procedures that must be operated for these papers are as detailed for operation under the 

GOLA assessment system. 

6. Practical Task Assessment 

6.1 General Requirements 

All Technical Certificate practical training activities are aimed at providing candidates with the 

practical competences to successfully complete the practical assessments required by the 

scheme. The awarding body has therefore developed a complete schedule of practical tasks which 

candidates must complete on a mandatory basis to successfully complete the practical units. 

All the assessment criteria in the practical tasks must be successfully met to complete the unit and 

achieve the award, additionally the assessment activity includes a maximum time duration within 

which the assessment activity must be conducted. Failure to complete in the time duration means 

that further training is required and the assessor will require the candidate to re-take the 

assessment activity. 

The task requirements are laid down in – 

• City & Guilds Level 2 Certificate in Basic Plumbing Studies - Practical Task Manual – Level 

2 Units 

• City & Guilds Level 3 Certificate in Domestic Plumbing Studies - Practical Task Manual –

6.5 Conditions for Practical Task Assessments 

The Practical Task Assessments within the Technical Certificate schedules in certain cases can 

contribute to evidence that is required to prove that the candidate is competent in the job 

performance requirements of the NVQs (see NVQ Handbook / Candidate Workplace Evidence 

Records for further details). 

The criteria for the Practical Task Assessments is detailed in the technical certificate 

document ‘Application of Practical tasks – Requirements for Centres’, the requirements of 

this document must be strictly adhered to by centres as a mandatory requirement of 

scheme approval and should be used alongside this scheme handbook. 

This criteria has been developed based on the guidance laid down in the Plumbing NVQ 

Assessment Strategy. 

6.6 Assessing Practical Tasks 

Compliance with the Assessment Criteria 

For each Practical Task within the Technical Certificate schedules there are set assessment 

criteria. These are the minimum and only criteria for the successful completion of the task – when 

a candidate has met these criteria he/she has successfully met the requirements of the task. 

Combining Practical Tasks 

The Practical Task Schedules indicate where tasks may be combined. In certain cases the task 

must be completed as a combined activity e.g. bathroom installation, it is not permissible for 

centres to adapt or modify the tasks and associated guidance in any way, in such a case the full 

bathroom activity must be undertaken as a single task. 

Where tasks are combined all the assessment criteria for all the separate tasks within the 

combined task must be met. 

Candidates failing to meet Assessment Criteria 

Where a candidate fails to meet all assessment criteria on a particular task he/she should be 

required to redo any defective installation (where this is feasible), to permit him/her to be reassessed 

on the failed assessment criteria. 

Where it is not feasible for the candidate to redo part of a task, or where there is a failure on the 

candidate’s part on the majority of assessment criteria for a task, then the candidate should redo 

the complete task. 


Observed assessments 

Certain tasks require the candidate to carry out procedures that - 

• Require a particular sequence of operations to be followed to achieve the intended task 

outcome 

• Have a potential safety hazard if not carried out correctly e.g. gas safety 

Tasks within this category must be observed by a person who has a certificated competence 

in the work process being assessed in addition to the assessor qualifications detailed 

earlier. 

Where a candidate fails any assessment criteria in this task category he/she should be required to 

repeat the complete assessment task 

6.7 Collecting and Recording the Outcomes of Practical Assessments 

The Technical Certificate support documentation includes: 

• Task Assessment Sheets which provide an outline of the task, the assessment criteria, and 

space for recording the candidate’s achievement of the task criteria 

• A Summary Task Achievement Record (Technical Certificate) on which can be recorded the 

individual candidate’s listed task achievements 

These documents should be retained by the Centre in secure storage. 

The information on these records (where relevant) will be transferred to NVQ Record Documents 

at an appropriate point. 

6.8 Use of NVQ Evidence towards 6129 Scheme Practical Tasks 

Practical Assessment tasks BI (bathroom installation) & AC (airing cupboard 

installation) 

These assessment activities may be provided as site based assessment activities as an 

alternative to plumbing centre based activities (through evidence produced from the 6089 

scheme) subject to the following conditions – 

Bathroom Installation (BI) Task 

• The on-site installation must comprise a minimum of bath, basin and WC which must be a part 

of a new installation or replacement of an existing bathroom suite. This must include the 

complete replacement of all hot and cold pipework within the bathroom (other than hot and cold 

supply tails entering the room). 

• The assessment activity must demonstrate activities are progressed to assessment standards 

laid down for the BI task 

• The installation of one appliance from the BI task must be subject to on-site direct observation 

by a qualified plumbing scheme assessor 


• The remaining evidence (including testing) can either be produced by: 

- on-site direct observation or product assessment by a qualified plumbing scheme assessor 

- job record/supplementary evidence which must be signed by an in-company workplace 

recorder who meets the requirements laid down in the Candidate Workplace Evidence 

Record for the 6089 award 

• All supplementary evidence requirements laid down for the BI assessment must be met in full if 

evidence from on-site is used 

Airing Cupboard (AC) Task 

• The on-site installation must comprise the installation of a hot water storage cylinder and cold 

water storage cistern which must be a part of a new installation or replacement of 

components which must include the replacement of the majority of the pipework in the airing 

cupboard location 

• The assessment activity must demonstrate activities are progressed to assessment 

standards laid down for the AC task 

• The installation of one component (either cistern or cylinder) and its subsequent pipework 

connections from the AC task must be subject to on-site direct observation by a qualified 

plumbing scheme assessor 

• The remaining evidence (including testing) can either be produced by on-site direct 

observation or product assessment by a qualified plumbing scheme assessor or be in the 

form of a job record/supplementary evidence which must be signed by an in-company 

workplace recorder who meets the requirements laid down in the Candidate Workplace 

Evidence Record for the 6089 scheme 

Note: 

Any supplementary evidence produced in support of either task must be subject to confirmation 

and checking by the plumbing scheme assessor using normal procedures carried out for validating 

evidence. 

7. Exemptions from practical & knowledge assessment tests 

There are no exemptions from technical certificate practical & knowledge assessment tests e.g. 

external ACS or unvented system assessment tests, as the technical certificate programmes 

provide the essential under-pinning learning to these programmes. Centres should therefore make 

recommendation to candidates/ their employers that course programmes are progressed in a 

logical sequence. 


8. Appeals and Equal Opportunities 

Centres must have their own, auditable, appeals procedure. If a candidate is not satisfied with the 

assessor’s judgement of his/her competence during the assessment process, or a candidate feels 

that the opportunity for assessment is being denied, the internal verifier and centre co-ordinator 

should, in the first instance, address the problem. If, however, the problem cannot be resolved, City 

& Guilds will arbitrate and the external verifier may be approached to offer independent advice. All 

appeals must be clearly documented by the centre co-ordinator and made available to the external 

verifier or City & Guilds if advice is required. 

Should occasions arise when centres are not satisfied with any aspect of the external verification 

process, they should contact City & Guilds regional or national office. 

Access to the NVQ framework is open to all, irrespective of gender, race, creed, age or special 

needs and there are no formal entry requirements. The centre co-ordinator should ensure that no 

candidate is subjected to unfair discrimination on any grounds in relation to access to assessment 

and to the fairness or the assessment. QCA requires City & Guilds to monitor centres to check 

whether equal opportunities policies are being adhered to. The City & Guilds equal opportunities 

policy appears in the Directory of NVQ Awards.

Plumbing Technical certificates should be referred to the relevant City & Guilds regional/national
