Heat-pump advice · Updated 5 September 2026
Is an air source heat pump right for your home?
An air-to-water heat pump uses electricity to move heat from outdoor air into your heating and hot-water system. A property assessment, realistic running-cost estimate and complete written quote help you decide what fits.
Understand heat-pump running costs →Questions to bring to a survey
- What does a room-by-room heat-loss assessment show?
- What radiator, pipework, cylinder and electrical changes are included?
- What seasonal performance and electricity prices support the running-cost estimate?
- What is the gross price, possible funding deduction and remaining amount I would pay?
Check the funding route separately
The Boiler Upgrade Scheme covers England and Wales subject to its current rules. Other UK nations have different routes. A possible grant does not mean the installation will be free.
Read current GOV.UK scheme guidance →Solar, heating and tariffs can be considered together
Use a consistent household energy picture when comparing proposals. Ask each provider to explain overlapping savings so the same electricity is not counted twice.
WarmHomeUK does not approve grants or carry out installation surveys. The guides help you prepare for those decisions.
