Up to 3 vetted, MCS-certified installers in your local area — chosen for the job, not the highest bid.

FAQ
For most well-insulated homes replacing an old gas boiler, running costs are roughly comparable to gas and significantly cheaper than oil or LPG. The bigger savings come from the £7,500 BUS grant and avoiding a £3–4k new boiler.
The Boiler Upgrade Scheme (Ofgem) gives £7,500 off an air-source or ground-source heat pump in England and Wales. Your MCS-certified installer applies on your behalf and the discount is taken off your quote directly.
A typical air source install takes 2–5 days. Ground source involves boreholes or trenches, so plan for 1–3 weeks. Your installer will confirm the timeline after the heat-loss survey.
Sometimes. Heat pumps run at lower flow temperatures, so 1–2 oversized radiators (typically in larger rooms) are common. Your installer will model this during the MCS heat-loss calculation.
Yes — free for homeowners. We are paid a small introduction fee by the installer only if you choose to go ahead, which means no upfront cost and no obligation for you.
