The £2,500 grant, plainly
Can I get the £2,500 grant for air conditioning in London or Hertfordshire?
Sometimes — and we'll tell you straight. Since April 2026 the government's Boiler Upgrade Scheme gives £2,500 towards an air-to-air heat pump (which is what modern air conditioning is) — but only when it replaces an existing fossil-fuel or electric heating system as your home's main heating, heats the whole home, and is installed to MCS-certified standards. It does not apply to cooling-only air con. Book a free survey and we'll confirm whether your home qualifies before you spend anything.
What qualifies
A home qualifies when an air-to-air heat pump replaces an existing fossil-fuel or electric heating system as the main heating for the whole home, the installation is carried out to MCS-certified standards, and the property is residential. All of these conditions need to be met, not just some of them.
Ofgem says new build properties are not eligible, with the exception of certain self-builds (built mainly using the labour or resources of the first owner, never owned by a business or organisation, and not part of an excluded property development).

- It’s an air-to-air heat pump — the heating-and-cooling system we install — used as heating.
- It replaces an existing fossil-fuel or electric heating system (Ofgem’s wording) as your home’s main heating.
- It heats the whole home, not just one or two rooms.
- The installation is carried out to MCS-certified standards.
- It’s a residential property, and not a new build — Ofgem says new builds are not eligible, except self-builds built mainly using the first owner’s labour or resources, never owned by a business or organisation, and not part of an excluded property development.
What doesn't
Cooling-only air conditioning does not qualify, nor does a unit added alongside a boiler you are keeping (Ofgem says hybrid systems are not eligible), a two- or three-room partial job, or any install done without MCS certification, whatever anyone promises. The scheme is for whole-home heating that replaces your existing heating.
- Cooling-only air conditioning — the system has to heat your home to qualify.
- A unit added alongside a boiler you’re keeping — it must replace it as your main heating.
- A two- or three-room partial job — the scheme is for whole-home heating.
- Any install done without MCS certification, whatever anyone promises.
If someone offers you “the grant” on a cooling-only unit, walk away — that's mis-selling, and it's your name on the paperwork.
How the money works
Where we're up to on this.
The grant is real, but it can only be claimed through an MCS-certified installer. We're getting set up to offer it, so right now we won't promise to knock £2,500 off your quote. We will check your home against the scheme's rules at a free survey and tell you plainly whether it qualifies. When our certification is live, this page will say so.
The grant, plainly
Is air conditioning really a heat pump?↓
Yes — an air-to-air heat pump moves heat rather than generating it. In summer it moves heat out of your room (cooling); in winter it moves heat in (efficient heating). One system, both seasons.
Does the grant apply to cooling-only air conditioning?↓
No. The Boiler Upgrade Scheme supports heat pumps as heating systems. It only applies when the system replaces an existing fossil-fuel or electric heating system as your main, whole-home heating. A cooling-only installation doesn't qualify, and anyone advertising otherwise is mis-selling.
Do I have to give up my boiler to get the grant?↓
Effectively yes — the grant is specifically for replacing an existing fossil-fuel or electric heating system with a heat pump as your home's primary heating, and Ofgem says hybrids with a boiler are not eligible. It isn't for adding air conditioning alongside a boiler you're keeping. We'll talk you through what that means for your home at the survey.
What is MCS certification and why does it matter?↓
MCS is the quality scheme grant-funded installations must be certified under. No MCS certification, no grant — it's that simple. We confirm the certification route on your quote before any work starts.
Can you apply the £2,500 for me right now?↓
Not yet — we're getting our MCS certification route in place. We won't promise a deduction we can't yet claim. Book a free survey and we'll confirm whether your home qualifies, and we'll update you the moment we can apply it for you.
How do I find out if my home qualifies?↓
Book a free survey. We check the property, the system fit and the scheme rules, and tell you plainly: eligible or not, and what the price is either way — before you commit to anything.
