Quick answer
Only in one specific case, yes. For a Kingston upon Thames 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 Kingston upon Thames, and what it means for the grant
There is nothing unusual about Kingston upon Thames's heating profile: roughly 82.9% mains gas and 16.3% electric, with the rest on oil, LPG or solid fuel. That ordinariness does not change what the grant needs from you - a genuine replacement of your existing heating, done by an MCS-certified installer.
Kingston upon Thames's heating, by the numbers
82.9% of Kingston upon Thames's EPC-certified homes heat on mains gas, 16.3% on electric and 0.2% on oil, LPG or solid fuel, typical annual heating costs across the property types we track here run around £568, 42% of rated homes sit at EPC band D, the local mode and the fuel-mix split above is drawn from 97.4% of Kingston upon Thames's EPC certificates, which makes it a genuine local measurement rather than a national average pinned to your postcode.
The two honest branches
Whether the grant pays for your Kingston upon Thames home comes down to a single decision: do you replace your heating, or keep it? We show both outcomes with equal weight, never as a blanket promise.
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 Kingston upon Thames plays no part in deciding whether you qualify. Planning permission for the outdoor unit in Kingston upon Thames, 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 Kingston upon Thames
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.
An air-to-air enquiry from Kingston upon Thames that qualifies for the grant goes to an MCS-certified installer; a cooling-only job goes to an F-Gas / REFCOM-registered engineer instead, since that is the licence refrigerant-only work actually requires. Mixing the two accreditations up is the mistake we see most often.

Frequently asked questions
Can I get the £2,500 grant for air conditioning in Kingston upon Thames?
Only in one specific case. The £2,500 applies when an air-to-air heat pump replaces your fossil-fuel or electric heating and is fitted by an MCS-certified installer. If you keep your existing heating and simply add cooling, that cooling-only add-on does not qualify, whatever it is marketed as.
Is the grant available in Kingston upon Thames right now, or is it coming later?
The rule applies in Kingston upon Thames now; the money does not flow yet. The air-to-air route of the Boiler Upgrade Scheme became law on 28 April 2026, so you can establish eligibility today, but vouchers cannot be issued until air-to-air products list on the MCS Product Directory, expected as air-to-air enters MCS scope on 5 December 2026. (Grant rules as of August 2026 and subject to change.)
Does my Kingston upon Thames 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 Kingston upon Thames 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 Kingston upon Thames?
The grant will not apply. Its whole basis is replacing and decommissioning existing heating, not adding to it. For a Kingston upon Thames home keeping its boiler, cooling is a private-pay install carried out by an F-Gas / REFCOM-registered engineer instead.
