Scotland is not covered by the Boiler Upgrade Scheme, so the advice written for English homeowners does not apply. The Scottish route is Home Energy Scotland funding, and it is arguably more generous.
What is available
Home Energy Scotland offers a grant of up to £7,500 towards an air source heat pump, with a rural uplift for eligible remote and island postcodes. On top of the grant you can usually apply for an interest-free loan to cover the remaining cost, spread over several years.
Funding is also available for insulation measures, which matters because heat pumps perform far better in a well-insulated home.
Typical Scottish costs
An air source heat pump install in Scotland generally runs £10,000 to £15,000 before funding, reflecting slightly higher heat loss in colder regions and larger required outputs. After grant support, most households end up paying a few thousand pounds, often financed through the interest-free loan.
The order of operations
- Get an installer survey and a written quote including heat loss calculations.
- Apply to Home Energy Scotland before any work begins.
- Wait for approval, then book installation.
Starting work before approval is the single most common way people lose their funding.
Getting quotes
Use an MCS certified installer — it is a condition of funding. Compare at least two quotes, and check each one prices the same heat pump output and cylinder size so the comparison is fair.
