Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Johnstone home, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.

How long is the heating season in Johnstone?

Heat pumps in Johnstone: questions
Do you cover Bridge of Weir as well as Johnstone?
Yes. We arrange surveys and installation in Bridge of Weir, which is about 3 miles north-west of Johnstone, and across Renfrewshire and Inverclyde.
How long does a heat pump survey take in Johnstone?
A home survey in Johnstone 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.
How soon can you survey a home in Johnstone?
Survey dates depend on how busy installers are in Renfrewshire and Inverclyde. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Johnstone?
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 Johnstone home gives a room-by-room list.
