Frequently asked questions about off-gas heat pumps in Scotland
Direct answers about costs, grants, supply constraints, installation, VAT, coverage areas and installer credentials.
Yes. An air source heat pump is a direct replacement for oil, LPG, electric storage or solid fuel heating in off-gas Scottish properties. A survey confirms suitability, but the technology is well established for these homes.
A constrained or single-phase supply changes what is possible. The network operator becomes part of the conversation from day one, and solar plus storage often has to be part of the answer rather than an add-on.
No. The Boiler Upgrade Scheme is England and Wales only and does not apply in Scotland. This is a key difference for Scottish property owners considering heat pump installation.
Yes. Zero percent VAT applies to qualifying domestic heat pump installations until 31 March 2027, as set by HMRC. This reduces the total cost of your installation.
The Smart Export Guarantee pays roughly 4p to 25p per kWh for exported electricity, depending on your supplier and tariff. This applies if your system includes solar generation that exports surplus to the grid.
Installation is carried out by our MCS-certified partner, Home Heating Services (Scotland) Ltd, who hold MCS certification number IAA10151, TrustMark registration 3559930, and Gas Safe registration 559575.
No. Ferry-only islands are not covered. We serve off-gas Scotland nationwide on the mainland and islands accessible by road bridge. If you are on a ferry-only island, we cannot help.
Costs vary by property size, heating demand and system design. We provide ranges with an illustrative caveat on every quotation, confirmed after a full property survey and heat loss calculation.
A typical installation takes two to four days depending on property size and complexity. This includes removing the old system, installing the heat pump and cylinder, upgrading radiators where needed, and commissioning the system.
Possibly. Heat pumps run at lower flow temperatures than oil or gas boilers, so some existing radiators may need upgrading to larger sizes. This is determined by the heat loss calculation during the survey and confirmed in your written quotation.
