Sunderland: £2,500 air-to-air heat pump grant

Sunderland is heavily on mains gas: around 93.5% of its EPC-certified homes heat this way, among the highest shares we track anywhere. For most readers here, the grant question is the straightforward one - does replacing that gas boiler with an air-to-air heat pump make sense - rather than a question about an unusual heating type.

Mains gas heats 93.5% of the EPC-certified homes in Sunderland, against 5.6% on electric and 0.6% on oil, LPG or solid fuel, a typical year's heating across the property types we profile here costs about £632, band D is the commonest EPC rating here, covering 38% of rated homes and this fuel-mix figure covers 99.5% of Sunderland's EPC certificates, so it is a real, high-confidence local read, not a national estimate applied to your postcode.

Whether the grant pays for your Sunderland 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 installer can be MCS-certified for air-to-air yet, so no Boiler Upgrade Scheme voucher can be issued today. Certified air-to-air products are already listed; installers can certify once the certification bodies gain UKAS accreditation, and MCS has not set a date for that. 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. The grant itself is a national government scheme - Sunderland Council has no say over your eligibility for it. If your Sunderland home also needs planning permission for the outdoor unit, that is a separate, local question our planning pages cover.

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.

From Sunderland, a grant-eligible air-to-air job is routed to an MCS-certified installer, while a pure cooling job goes to an F-Gas / REFCOM-registered engineer - the licence that covers refrigerant-only work. Homeowners researching this grant mix the two up more than anything else.
