Grants and rules for heat pumps in Scotland

Instead, homeowners in Dumbarton can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.

Designing for Dumbarton's winters
On the shortest day Dumbarton gets only about 6 hours 57 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

Heat pump grants in Dumbarton: questions
How soon can you survey a home in Dumbarton?
Survey dates depend on how busy installers are in Glasgow and Dunbartonshire. We offer the next available dates when you enquire and confirm them in writing.
How long does a heat pump survey take in Dumbarton?
A home survey in Dumbarton usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Where would the outdoor unit go on a Dumbarton house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Dumbarton home.
How much is the heat pump grant?
It depends on where you live. In England and Wales, the Boiler Upgrade Scheme pays £7,500 towards an air-to-water heat pump, or £9,000 when replacing oil or LPG heating for installations from 21 July 2026 to 31 March 2027. In Scotland, Home Energy Scotland offers up to £7,500, plus a rural uplift and an optional loan. Northern Ireland has no dedicated grant at present.
Can I start work before my Home Energy Scotland offer arrives?
No. In Scotland you must receive a written funding offer from Home Energy Scotland before work starts, otherwise the work may not be funded. We plan the installation date only once your offer is confirmed. Funding is first come, first served, so it helps to apply once you have your written quote.
