Scottish properties (PA, G, EH etc.) qualify for the Home Energy Scotland grant. All other UK properties qualify for the Boiler Upgrade Scheme.
How the estimate is calculated
Heat Loss Calculation
We apply a simplified BS EN 12831 methodology using your property type, age, floor area (estimated from bedrooms), and EPC rating to calculate how many kilowatts of heat your home needs.
Grant & Cost Sizing
Your postcode determines whether the Boiler Upgrade Scheme (BUS) or Home Energy Scotland (HES) grant applies. We then size the correct heat pump and calculate net cost after grant deduction using 2024 UK market rates.
Savings & Carbon
Annual savings are calculated by comparing your current fuel cost (at Ofgem 2024 benchmark tariffs) against the heat pump's electricity consumption adjusted for its efficiency (SCOP) rating.
Important: These estimates are indicative. For a binding quote and to claim your government grant, our MCS-accredited engineers will carry out a free, no-obligation home survey — measuring every room to the full BS EN 12831-1:2017 standard.
