Quick answer
There is one route where it pays, and one where it does not. An air-to-air heat pump installed in Eastleigh attracts the £2,500 Boiler Upgrade Scheme payment when it replaces fossil-fuel or electric heating via an MCS-certified installer - the same unit cools your home each summer and heats it each winter. Keep your existing boiler and simply bolt on cooling, and the grant is not available.
Heating in Eastleigh, and what it means for the grant
Like most of the areas we cover, Eastleigh sits close to the national pattern: around 88.9% of its EPC-certified homes heat on mains gas, 10.1% on electric, and a small remainder on oil, LPG or solid fuel. Whichever describes your home, the £2,500 grant works the same way: it pays when you replace that heating with an air-to-air heat pump fitted by an MCS-certified installer.
Eastleigh's heating, by the numbers
88.9% of Eastleigh's EPC-certified homes heat on mains gas, 10.1% on electric and 0.7% on oil, LPG or solid fuel, typical annual heating costs across the property types we track here run around £481, the most common EPC band locally is C (41% of rated homes) and the fuel-mix split above is drawn from 99.2% of Eastleigh's EPC certificates, which makes it a genuine local measurement rather than a national average pinned to your postcode.
The two honest branches
Everything about whether the grant pays a Eastleigh homeowner turns on one choice: replacing the existing heating, or leaving it in place. We set out both routes with the same weight, not as a blanket promise either way.
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 Eastleigh Council plays no part in deciding whether you qualify. Planning permission for the outdoor unit in Eastleigh, 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 Eastleigh
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 Eastleigh 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 Eastleigh?
Yes, but only in that one case. The £2,500 is paid when an air-to-air heat pump replaces existing fossil-fuel or electric heating and an MCS-certified installer fits it. Simply adding cooling on top of your existing heating does not qualify, no matter how the job is sold to you.
Is the grant available in Eastleigh right now, or is it coming later?
Live in law, not yet in practice. Eastleigh is covered by the air-to-air pathway of the Boiler Upgrade Scheme exactly as the rest of England is, and has been since 28 April 2026 - but until air-to-air products appear on the MCS Product Directory no installer can generate a compliant voucher. That gate lifts as air-to-air enters MCS scope on 5 December 2026. (Grant rules as of August 2026 and subject to change.)
Does my Eastleigh installer need to be MCS-certified?
Yes, if you want the grant. The Boiler Upgrade Scheme only pays out when the air-to-air heat pump is fitted by an MCS-certified installer - that certification covers registered installers, never the homeowner. A cooling-only job in Eastleigh sits outside MCS entirely and needs an F-Gas / REFCOM-registered engineer.
What if I want to keep my gas boiler and just add air conditioning in Eastleigh?
Then the grant does not apply. It only pays when the heat pump replaces your existing heating and that heating is decommissioned. Keeping the boiler and adding cooling in Eastleigh is a private-pay job for an F-Gas / REFCOM-registered engineer, not a grant job.
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 Eastleigh 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.
