Air to Air Heat Pump Grant in Scotland

The honest answer for Scotland

If you live in Scotland and you are hoping to fund an air-to-air heat pump — the reversible, air-conditioning-style units that heat your rooms in winter and cool them in summer — there is no grant for you as at July 2026. The £2,500 Boiler Upgrade Scheme grant that made air-to-air eligible on 28 April 2026 covers England and Wales only. Home Energy Scotland, the devolved scheme that funds heat pumps north of the border, excludes air-to-air outright. What you can still claim, wherever you live in the UK, is 0% VAT on the supply and installation. That is a price cut, not a grant, and for air-to-air it is the whole of the Scottish offer.

Why the Boiler Upgrade Scheme does not reach Scotland

The Boiler Upgrade Scheme (BUS) is an England-and-Wales programme, administered by Ofgem. It was BUS that, from 28 April 2026, added air-to-air heat pumps at a flat £2,500 grant — the first UK government money ever offered for air-conditioning-style heating. But home heating policy is devolved, and Scotland runs its own funding through Home Energy Scotland rather than through BUS. So the £2,500 simply does not exist here, no matter which installer you ask or how the offer is worded. If a company tells you they can secure you the Boiler Upgrade Scheme grant on a Scottish property, they are mistaken. You can confirm the geographic limit yourself on the scheme guidance at gov.uk (as at July 2026).

Why Home Energy Scotland will not fund air-to-air

Scotland's route to a funded heat pump is the Home Energy Scotland Grant and Loan, and it is genuinely generous. But it carries a hard technical condition that air-to-air cannot meet: the system must provide 100% of your home's space heating and your domestic hot water. Air-to-air makes no hot water at all — that is inherent to how it works, because it warms the air in your rooms rather than heating water in a cylinder. Failing the hot-water test rules it out of Home Energy Scotland completely, in exactly the same way it is excluded from ECO4 for the same reason. So in Scotland there is no grant and no interest-free loan for an air-to-air system. You can read the current funding criteria on the Home Energy Scotland site (as at July 2026).

What every Scottish homeowner still gets: 0% VAT

The one national measure that does reach you is 0% VAT on the supply and installation of a permanently fixed air-to-air unit that provides heating. Under HMRC VAT Notice 708/6 this applies UK-wide — England, Wales, Scotland and Northern Ireland — until 31 March 2027, after which it rises to 5% rather than the standard 20%. On a typical £4,500 installation, zero-rating is worth roughly £900 against what you would otherwise pay in VAT. Two caveats: the relief covers heating, so a cooling-only unit does not qualify, and the saving is applied by your installer within the quoted price rather than reclaimed later. The full rules are set out by HMRC (as at July 2026).

If you want funding, consider air-to-water instead

If a grant matters more to you than the specific technology, the funded path in Scotland is an air-to-water heat pump. Because air-to-water heats a cylinder and can cover both your space heating and your hot water, it satisfies Home Energy Scotland's criteria. As at July 2026 the Home Energy Scotland Grant and Loan offers a grant of up to £7,500, with an additional rural and islands uplift, plus an optional interest-free loan on top. That is a very different proposition from air-to-air: worth weighing honestly if your real goal is a funded, whole-home switch away from fossil heating.

Air-to-air vs air-to-water in Scotland

Feature	Air-to-air	Air-to-water
Scottish grant/loan	None	Home Energy Scotland grant + interest-free loan
0% VAT (to 31 Mar 2027)	Yes	Yes
Provides hot water	No — keep a separate cylinder or immersion	Yes
Provides summer cooling	Yes	No
Emitters needed	Wall or ceiling heads only	Radiators or underfloor
Best suited to	All-electric, storage-heater and flatted homes wanting low-cost heat plus cooling	Homeowners wanting a funded whole-home switch

Is air-to-air still worth it in Scotland without a grant?

Sometimes, yes — and it is worth being clear-eyed about when. If your home runs on storage heaters or direct electric radiators, an air-to-air heat pump can still make sense on running cost alone. At the Ofgem price cap for 1 July to 30 September 2026 (electricity 26.11p/kWh, gas 7.33p/kWh, per Ofgem), a unit with a seasonal efficiency of around 4.0 delivers heat at roughly 6.5p per useful kWh — far below the price of direct electric or peak-rate storage heating. A move from old storage heaters typically saves in the region of £500 to £900 a year, not the inflated figures some adverts quote, because storage heaters ran on cheaper night-rate units in the first place. Add the low installation cost and 0% VAT, and the numbers can work even paying the full price. If, however, you heat with mains gas or you want a funded, whole-house solution, air-to-water via Home Energy Scotland is almost certainly the better route for you.

What to do next

• Decide what you actually want. Cheaper controllable heat and summer cooling for an all-electric or flatted home points to air-to-air; a funded whole-home switch points to air-to-water.
• If air-to-air suits you, get quotes with the 0% VAT already applied, and confirm the unit is specified for heating, not cooling only, so the relief holds.
• If funding is the priority, check your eligibility for the Home Energy Scotland Grant and Loan for an air-to-water system before committing to anything.
• Keep your hot water sorted. Air-to-air makes none, so plan to retain an immersion, cylinder or hot-water heat pump alongside it.

We connect genuinely eligible homeowners with the right installers rather than selling a particular brand of kit. In Scotland that means being straight with you: there is no air-to-air grant here, only 0% VAT — and we would rather tell you that now than let you chase money that does not exist.
