Estimator
Heat pump & solar savings calculator
An honest first-pass estimate, using the same efficiency assumptions our engineers use at survey. You see the result immediately — no email gate, no sales call before you get a number.
This is an indicative model, not a quotation. Real figures come from a room-by-room heat loss survey, which is free.

Air source heat pump
Grant eligibility
What you may be entitled to
Boiler Upgrade Scheme: £7,500. For an air source heat pump. Paid to the installer and deducted from your quotation. Only an MCS accredited installer can make the application; ours is NIC601962.
Air-to-air systems: £2,500. Often the right answer for a property with no gas supply.
VAT relief. 0% VAT on qualifying energy-saving installations, heat pumps and solar included.
ECO4. Cannot be judged from the answers above: eligibility depends on household income and benefits received, not on the property. See the qualifying criteria in our grants guide.
Want the real number?
A room-by-room heat loss survey and a roof shading assessment turn this estimate into a quotation. Both are free and there is no obligation.
