Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply 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.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Dumbarton property at survey.

Heat pumps in Dumbarton: questions
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 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.
Do I need new radiators for a heat pump in Dumbarton?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Dumbarton home gives a room-by-room list.
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.
