Housebuilders will be able to construct and sell net-zero homes without increasing current build costs as Wondrwall launches its Energy Service Contracts (ESC) to UK housebuilders removing the ‘green premium’ to building net-zero energy homes.

Using a service charge style model, homeowners pay back the Low Carbon Technology (LCT) investment through a fixed monthly charge over a 20-year contract in a ‘first of its kind’ in the UK market, enabling all new build homes to be net-zero energy from build, without incremental costs to the housebuilder or homeowner. Hardware costs and upgrades to both the battery and inverter throughout the lifetime of the energy service contract will be subsidised by Wondrwall.

Daniel Burton, CEO of the Wondrwall Group, said, “We need to make this decade a catalytic moment for change in the housebuilding industry. Currently, we are still building the retrofit homes of the future. Wondrwall ESC has the potential to change this. With ESC, it is like offering homeowners a self-driving electric car, for the same cost as a dirty diesel but with lower running costs.”

With only 4 per cent of new homes in England and Wales built to the highest EPC A rating last year, Installation of renewable energy technologies, including solar PV generation, hybrid inverters, battery storage and EV charging and could increase the figure to closer to 80 per cent of all new developments being immediately EPC A rated, accelerating planning permission timescales and new higher regulatory requirements to the Future Homes Standard.
