0% VAT on Heat Pumps

Applied automatically until 31 March 2027. Saves £2,400-£4,000 on a typical heat pump installation. No application needed — already reflected in our prices.

Warmer Homes Scotland

Fully funded heat pump for qualifying low-income households. Apply via Home Energy Scotland (0808 808 2282). Covers full cost of heat pump and insulation improvements.

Boiler Upgrade Scheme — England & Wales Only

The BUS (£7,500 grant) is not available in Scotland. Scotland has the HES Grant instead, which provides the same £7,500 grant plus an additional £7,500 interest-free loan — making it more generous than the English scheme.

Solar + Heat Pump — The Ultimate Combination

Pair your heat pump with solar panels to generate free electricity for your heating. Solar provides 30-50% of your heat pump's annual electricity demand, dramatically reducing running costs.

Heat Pump FAQ — Scotland

Air source heat pump installation in Scotland typically costs £12,000-£18,000 depending on property size and system requirements. After the Home Energy Scotland (HES) Grant of up to £7,500 (£9,000 for rural properties with the £1,500 rural uplift), your net cost could be as low as £3,000-£9,000. A further £7,500 interest-free loan is available, meaning you could pay nothing upfront.

The HES Grant provides up to £7,500 towards heat pump installation for Scottish homeowners (£9,000 for eligible rural properties with the £1,500 rural uplift). On top of the grant, a £7,500 interest-free loan is available, giving you up to £15,000-£16,500 total funding. The grant is active and ongoing as of 2026. You must use an MCS-certified installer like Scottish Energy Efficiency to qualify.

Yes. Modern air source heat pumps operate efficiently down to -20 degrees Celsius. Scotland's average winter temperature of 2-5 degrees Celsius is well within the optimal range. Scandinavian countries with far colder climates use heat pumps extensively. We size every system specifically for Scottish conditions, ensuring reliable performance year-round.

Yes. An air source heat pump can fully replace your gas boiler for both heating and hot water. Heat pumps produce lower temperature heat than gas boilers, so some radiators may need upsizing. We assess this during your free survey and include any necessary radiator upgrades in our quote. Underfloor heating works exceptionally well with heat pumps.

Savings depend on your current fuel type. Replacing an older gas boiler saves £200-£500/year. Replacing oil heating saves £500-£1,000/year. Replacing LPG saves £600-£1,200/year. Replacing electric heating saves £300-£700/year. Heat pumps deliver 3-4 units of heat for every 1 unit of electricity used, making them significantly more efficient than any combustion-based heating.

Yes. Heat pump installations qualify for 0% VAT until 31 March 2027. On a £14,000 installation, this saves you £2,800 compared to the standard 20% VAT rate. Combined with the HES Grant (up to £7,500), you could pay as little as £3,700 for a complete heat pump system.

Heat pump installation typically takes 2-4 days depending on system complexity and whether radiator upgrades are needed. From initial enquiry to completed installation takes 8-16 weeks, which includes the HES Grant application process (4-8 weeks). We manage the entire grant application on your behalf.

Air source heat pumps are Permitted Development in Scotland for most residential properties, so no planning permission is required. The unit must be at least 1 metre from the property boundary. Listed buildings and properties in conservation areas may need consent. We assess this during your free survey.

Yes, and it is an excellent combination. Solar panels generate free electricity during the day, which powers your heat pump at zero marginal cost. A 4.5kWp solar system can provide 30-50% of a heat pump's annual electricity demand. Combined with battery storage and Octopus Flux, you can run your heat pump almost entirely on renewable energy.

We install air source heat pumps from Vaillant (Arotherm Plus), Daikin (Altherma), and Mitsubishi Electric (Ecodan). All are established, reliable brands with 7-year manufacturer warranties and excellent performance in Scottish conditions. We recommend the best brand for your specific property and heating requirements.

Gas Boilers in Scotland

For homes in Scotland with mains gas, a high-efficiency A-rated condensing boiler is often the fastest solution when a boiler fails. Modern combi and system boilers from Worcester Bosch, Baxi, and Glow-Worm achieve 92-94% efficiency, significantly reducing running costs compared to older models. A gas boiler replacement in Scotland typically costs £1,800-£3,500 installed depending on system type and complexity. Like-for-like gas boiler swaps are not eligible for HES grant funding — the grant is reserved for clean-heat upgrades such as heat pumps. If you're considering a longer-term move away from gas, the Alternative Heating tab covers funded options including air source heat pumps with up to £7,500 grant plus £7,500 interest-free loan.

Heating installations are carried out by our Gas Safe registered partner, Home Heating Services (Scotland) Ltd.

Heating FAQ — Scotland

What heating systems can I get installed in Scotland?+
Homes in Scotland can choose from gas boilers (where mains gas is available), oil boilers, LPG boilers, air source heat pumps, hybrid heating systems, solar thermal, electric boilers, and modern ceramic/infrared electric heating. The best option depends on your property type, existing fuel supply, and whether you want to access Scotland's HES grant funding. Our partner Home Heating Services (Scotland) Ltd (Gas Safe 559575) installs all types. Call 0141 230 0198 for advice.
Should I replace my boiler or switch to a heat pump in Scotland?+
If your existing gas, oil, or LPG boiler has failed and you need immediate heating, a like-for-like replacement is the fastest option (1-3 days). However, switching to a heat pump qualifies for up to £7,500 HES grant (£9,000 rural, grant only) plus £7,500 interest-free loan and 0% VAT until March 2027 — making it significantly cheaper long-term. Heat pumps also cut running costs by 30-50% versus oil or LPG. We recommend a free survey to compare options for your Scotland home.
Is there funding for heating upgrades in Scotland?+
Yes. The Home Energy Scotland (HES) scheme provides up to £7,500 non-repayable grant (£9,000 for rural properties, uplift on the grant only) plus an interest-free loan of up to £7,500 for heat pump installation. 0% VAT applies to heat pumps until 31 March 2027. ECO4 (means-tested, extended to December 2026) may fully fund heating upgrades for qualifying households. Note: like-for-like gas/oil boiler swaps do not qualify for HES funding. The Warm Homes Plan is England-only and does not apply in Scotland.
How quickly can a broken boiler be replaced in Scotland?+
A like-for-like gas or oil boiler replacement in Scotland can typically be completed within 1-3 days from survey. Emergency replacements may be faster. Heat pump installation takes longer (2-4 days on-site plus 8-16 weeks for HES grant application), so if you need immediate heating, a boiler swap may be the right interim solution. Our partner Home Heating Services (Scotland) Ltd handles both emergency replacements and planned upgrades.
What heating suits an off-gas home in Scotland?+
Off-gas homes in Scotland typically use oil, LPG, or electric heating. The most cost-effective upgrade path is switching to an air source heat pump, which qualifies for HES grant funding (up to £9,000 for rural properties plus £7,500 loan). Modern ceramic electric heating or infrared panels suit flats and hard-to-treat properties. Solar PV paired with battery storage can significantly reduce electric heating costs. We assess all options during a free home survey.
Who carries out the heating installation?+
All heating installations — gas, oil, LPG, heat pump, and electric systems — are carried out by our partner Home Heating Services (Scotland) Ltd, based in Perth. They hold Gas Safe registration 559575, MCS certification IAA10151, and are registered with HIES, RECC (00077024), and TrustMark (3559930). They cover central Scotland and beyond. Scottish Energy Efficiency connects you with them and handles the enquiry and grant paperwork.
