Quick answer

Only in one specific case, yes. For a Barnet home, the Boiler Upgrade Scheme pays £2,500 towards an air-to-air heat pump - a unit that both cools in summer and heats in winter - provided it replaces fossil-fuel or electric heating and an MCS-certified installer fits it. Add cooling while keeping your existing boiler, and that route does not qualify.

Heating in Barnet, and what it means for the grant

Heating in Barnet follows a fairly ordinary England-wide split: about 84.2% mains gas, 15.3% electric, and a small tail on oil, LPG or solid fuel. Whatever your own home runs on, the grant rule is the same everywhere - replace it with an air-to-air heat pump via an MCS-certified installer and the payment applies.

Barnet's heating, by the numbers

The split across Barnet's EPC-certified stock is 84.2% mains gas, 15.3% electric and 0.2% oil, LPG or solid fuel, typical annual heating costs across the property types we track here run around £566, band D is the commonest EPC rating here, covering 43% of rated homes and the fuel-mix split above is drawn from 92.9% of Barnet's EPC certificates, which makes it a genuine local measurement rather than a national average pinned to your postcode.

The two honest branches

For a Barnet home, one decision settles whether the grant pays: replace your heating, or keep it. Both outcomes below carry equal weight - neither is the "default" answer.

Eligible - you replace your heating. If an air-to-air heat pump replaces a fossil-fuel or electric system (mains gas, oil, LPG, electric storage heaters or direct electric) and is fitted by an MCS-certified installer, the £2,500 applies, and the old system is decommissioned rather than run alongside the new one.

Not eligible - you keep your boiler. If you keep your existing heating and add cooling as a standalone unit, that cooling-only add-on does not qualify for the Boiler Upgrade Scheme grant, however it is marketed. Adding air conditioning while keeping your gas boiler is a private-pay job, carried out by an F-Gas / REFCOM-registered engineer rather than an MCS-certified one.

The grant itself is law and your eligibility is real, but no air-to-air product has reached the MCS Product Directory yet, so no installer can issue a Boiler Upgrade Scheme voucher today. Air-to-air enters MCS scheme scope on 5 December 2026, and vouchers follow once certified products list. Get quotes now, but treat the grant as pending rather than banked.

Grant rules as of August 2026 and subject to change, so always confirm the current terms on gov.uk before applying. This is a national scheme, so the London Borough of Barnet plays no part in deciding whether you qualify. Planning permission for the outdoor unit in Barnet, if you need it, is a different and entirely separate matter, covered on our planning pages.

What MCS means for a grant-eligible install in Barnet

MCS - the certification scheme for registered installers - is the quality standard your installer must hold for the grant to pay. It certifies the installer and the installation work, never the homeowner and never GetComfort.

We route a grant-eligible air-to-air enquiry from Barnet to an MCS-certified installer, and a cooling-only job to an F-Gas / REFCOM-registered engineer instead, because refrigerant-only work is what those engineers are licensed for. Confusing the two is the single most common mistake homeowners make when researching this grant.

Frequently asked questions

Can I get the £2,500 grant for air conditioning in Barnet?

In one specific situation, yes. The £2,500 pays out when an air-to-air heat pump replaces your existing fossil-fuel or electric heating, fitted by an MCS-certified installer. Keep your existing heating and just add cooling instead, and that add-on does not qualify, however it is described.

Is the grant available in Barnet right now, or is it coming later?

Both, in a sense. The air-to-air pathway of the Boiler Upgrade Scheme has been law since 28 April 2026 and covers Barnet like everywhere else in England, so your eligibility is real today. What is not yet possible is the payment: no air-to-air product has reached the MCS Product Directory, so no installer can issue a voucher. Air-to-air enters MCS scheme scope on 5 December 2026. (Grant rules as of August 2026 and subject to change.)

Does my Barnet installer need to be MCS-certified?

For the grant, yes. The Boiler Upgrade Scheme only pays when an MCS-certified installer fits the air-to-air heat pump - MCS is the certification scheme for registered installers, not a homeowner qualification. A cooling-only air-conditioning job in Barnet does not go through MCS at all; it needs an F-Gas / REFCOM-registered engineer instead.

What if I want to keep my gas boiler and just add air conditioning in Barnet?

The grant will not apply. Its whole basis is replacing and decommissioning existing heating, not adding to it. For a Barnet home keeping its boiler, cooling is a private-pay install carried out by an F-Gas / REFCOM-registered engineer instead.

Every home is different - your floor, aspect, EPC band, heating type and conservation status all change the answer. Our free cooling checker pre-fills your home from public property data (EPC and UPRN records) and settles a property-specific verdict for your Barnet home immediately on screen: an overheating score, the right system, whether you genuinely qualify for the grant, the planning position and a net cost. No phone call, no waiting.
