New Homes, New Rules: Net Zero Expert Responds to Solar Panel Mandate

Posted by Construction Industry News Magazine on 13th June 2025 -

The government last week revealed its plans to double down on its net zero ambitions by mandating the installation of solar panels on the majority of new homes. It means the Future Homes Standard (FHS), set to be published in autumn, will likely require new builds to have solar panels and heat pumps by default. 

David Woon, head of net zero engineering and operations at Ennovus Solutions, a leading net zero consultancy, today issued a statement in response to the decision.

“This is incredibly positive news, and I agree that it makes sense for all new builds to incorporate solar energy. However, the true benefit will be realised if this mandate is implemented in a way that maximises the potential of each installation, rather than simply meeting a minimum requirement. We too often observe new builds fitted with just one or two panels, which significantly limits the long-term advantages for both the homeowner and the environment.

“A more substantial solar array will not only help homeowners by significantly lowering their energy bills but also contribute more effectively to our planet by generating greater amounts of clean, green energy. Furthermore, a larger system can help to accelerate the ‘carbon payback period’ of the entire installation, especially for components like inverters, which will have a relatively fixed embodied carbon from their manufacturing and transport. Sourcing equipment, particularly from European manufacturers where possible, can also help mitigate this.

“The principles of maximising solar potential, ensuring quality installations, and evaluating contractors comprehensively are also just as vital in the commercial sector. This is a positive step forward for renewable energy in the UK, and we look forward to seeing how these plans develop.”

Addressing potential concerns about cost, David added: “While price will naturally be a key consideration, it’s crucial that installations are completed safely, using high-quality equipment, and adhering to established industry guidance such as the IET Code of Practice for Grid Connected Solar PV, MCS The Solar PV Standard, and RC62 Recommendations for Fire Safety with PV Panel Installations. This shouldn’t become a ‘race to the bottom’ on price. Contractors should be evaluated not just on cost, but equally on their commitment to Safety, Health, Environment, and Quality (SHEQ).”
