Yes. Battery storage qualifies for 0% VAT when installed alongside solar panels or added to an existing solar installation. This applies until 31 March 2027. The 0% rate is applied automatically.
Standard battery installations do not provide backup during grid outages for safety reasons. However, Tesla Powerwall and some other systems offer optional EPS (Emergency Power Supply) or backup gateway features that can power essential circuits during outages. This requires additional hardware at installation. Ask us about backup options during your survey.
Battery installation takes half a day to one full day depending on system complexity. If added during a new solar installation, it adds no extra time. Retrofit installations to existing solar systems typically take one day including inverter replacement if needed. From enquiry to installation takes 3–6 weeks.
For a typical Scottish home with 4.5kWp solar, a 5kWh battery covers evening usage while a 9.5kWh battery provides near-complete overnight coverage. Larger homes or those wanting maximum export returns should consider 9.5–13.5kWh. We design the optimal size during your home survey based on your actual energy usage data.

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. If you're considering a longer-term move away from gas, the Alternative Heating tab covers clean-heat options including air source heat pumps. Interest-free credit up to £30,000, subject to status.
Heating installations are carried out by our Gas Safe registered, MCS-certified partners.
Some properties in Scotland rely on oil heating, particularly those in more rural areas. Oil boiler replacements remain an option where a system has failed, but oil prices are volatile and running costs are typically higher than gas or heat pump alternatives. A replacement oil boiler costs £3,000-£5,500 installed in Scotland. Switching from oil to an air source heat pump is a clean-heat upgrade that benefits from 0% VAT until 31 March 2027. Interest-free credit up to £30,000, subject to status. For off-gas Scotland homes, moving from oil to a heat pump is a worthwhile long-term upgrade. See the Alternative Heating tab for details.
Heating installations are carried out by our Gas Safe registered, MCS-certified partners.
LPG (liquefied petroleum gas) boilers serve off-gas-grid homes in Scotland as an alternative to oil. They are cleaner-burning than oil but remain a fossil fuel with volatile pricing. An LPG boiler replacement typically costs £2,200-£4,000 installed. Running costs are generally comparable to oil heating, though LPG tanks require regular deliveries and rental agreements. Switching from LPG to an air source heat pump in Scotland is a clean-heat upgrade with 0% VAT until 31 March 2027. Interest-free credit up to £30,000, subject to status. We handle the full transition from LPG to heat pump, including decommissioning.

For Scotland homes already investing in solar or battery storage, pairing with a heat pump creates a highly efficient, low-carbon heating system. Air source heat pumps work by extracting warmth from outside air, even in cold weather, and delivering it indoors via radiators or underfloor heating. 0% VAT applies until 31 March 2027. Interest-free credit up to £30,000, subject to status. Hybrid systems (heat pump plus existing boiler) suit older properties where a full switch isn't immediately practical. Solar thermal and biomass boilers may also be considered in Scotland where appropriate. All clean-heat installations are carried out by our Gas Safe registered, MCS-certified partners.

Electric heating pairs particularly well with solar panels and battery storage in Scotland — using stored solar energy for heating reduces running costs. High-retention ceramic storage heaters, electric boilers, and infrared panels are increasingly popular in Scotland for flats, hard-to-treat properties, and homes without gas. They require no annual servicing, produce zero local emissions, and suit properties where heat pump installation is impractical (e.g. tenements without outdoor space). Running costs are higher than heat pumps but lower than older electric systems, especially on time-of-use tariffs. Ceramic heaters retain heat for 8-12 hours, releasing it gradually. When combined with solar PV and battery, electricity costs can be lower during daylight hours.

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 move to clean heating. Our Gas Safe registered partners install 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). Switching to a heat pump is a clean-heat upgrade that benefits from 0% VAT until March 2027. Interest-free credit up to £30,000, subject to status. Heat pumps also reduce running costs compared to oil or LPG. We recommend a no-obligation survey to compare options for your Scotland home.
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). If you need immediate heating, a boiler swap may be the right interim solution. Our partners handle 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. A cost-effective upgrade path is switching to an air source heat pump, which benefits from 0% VAT until 31 March 2027. Interest-free credit up to £30,000, subject to status. Modern ceramic electric heating or infrared panels suit flats and hard-to-treat properties. Solar PV paired with battery storage can reduce electric heating costs. We assess all options during a no-obligation home survey.
Who carries out the heating installation?+
All heating installations — gas, oil, LPG, heat pump, and electric systems — are carried out by our MCS-certified, Gas Safe registered installation partners. They cover central Scotland and beyond. Scottish Energy Efficiency connects you with them and handles the enquiry paperwork.
