SOLAR PV & FHS HOW TO STAY AHEAD OF THE CURVE AS THE FUTURE HOMES STANDARD LOOMS The Future Homes Standard (FHS) is still two years away, but the specification industry should be investing time and resources now to fully understand how renewable technologies such as solar PV will be critical to success in a new regulatory landscape. Stuart Nicholson, Roof Systems Director at Marley, explains how technical product, installation support and bespoke training modules can help specifiers fully prepare for smart roof specification. The construction sector is now implementing the practical design, specification and building steps demanded by a new era. The landmark amendments to Part L of the Building Regulations introduced in 2022 are now a reality, making it mandatory that new homes are designed to create sustainable, low carbon emitting dwellings in line with the national net zero target set for 2050. But more critical change is on the horizon and the specification industry is expected to react accordingly. In just two years’ time, the government will launch the Future Homes Standard (FHS), which will set the specification template to drive the construction of energy efficient houses which must produce 80% less carbon emissions than those allowed under the current regulations. Renewable technologies will play a central part in how this will be achieved and will encompass many areas including thermal efficiency, the building fabric and the impact of roofscapes. And while the Part L changes are influencing current thinking and industry responses, the 80% reduction demand that will be enshrined within the Future Homes Standard is a step-change for all stakeholders. And in a sure sign of the direction of travel, there are strong indications – as the FHS detail is finally agreed ahead of launch – that solar PV on the roof will be a mandatory renewable technology solution, offering a practical, affordable and high performing answer that the construction sector needs to embrace. Indeed, of the six FHS specifications under government consideration, five include solar PV technology. Solar is currently only installed on approximately 10% of all new builds in England and Wales. Yet estimates forecast that we will see around 160,000 of the annual 200,000 new houses being constructed specified with a form of solar PV. This is in part due to the direct influence of the Part L amendments and in preparation for the seismic change the Future Homes Standard will bring. It is also important for specifiers to note that legacy issues associated with solar PV are no longer relevant, Contact whether for new builds or retrofit MCS projects.

The SolarTile roof panels replace standard roofing tiles or slates, giving owners the benefit of both a weatherproof roof covering and electricity generating solution. reduced dramatically over the past decade, whilst the ability to seamlessly install innovations such as Marley’s SolarTile, as part of a fully integrated roofing solution, offsets prevailing concerns about aesthetics. Marley sits at the forefront of the rooftop revolution taking place as the construction sector pivots to tackle a new regulatory landscape, and solar is a central component of a fully integrated roofing system; one that is tried, proven and underpinned by a 15- year warranty. For example, a bespoke online Marley CPD is already available to specifiers. It provides the background and technical information specifiers looking to increase their knowledge of solar PV require. Marley can also assist with informed roof product specification choices such as thermally efficient roof tiles, and areas such as after installation that make positive contributions to the overall energy efficiency of future homes. Get in the know with solar Marley is also actively engaged with housebuilders, local authorities and commercial enterprises, communicating the installation ease and performance benefits delivered by solar PV.
