Finding a heat pump installer in Cambridgeshire: every company listed on this page is cross-checked against the official MCS certified register. MCS certification matters because only an MCS-certified installer can claim the £7,500 Boiler Upgrade Scheme grant on your behalf — it is a hard requirement of the scheme, not a preference. Listings are free and ranked alphabetically; the single paid Featured slot per area is clearly badged as such. Use the search and filters below to find installers near you, then verify certification directly at mcscertified.com before you commit.
Before any grant, for a standard 3-4 bedroom home. Ground source systems typically cost more due to the groundworks needed for the ground loop.
Available for air source and ground source heat pumps in England and Wales, applied upfront by your MCS-certified installer and deducted from your invoice — no repayment, no income cap.
A temporary uplift for eligible off-gas-grid properties, running 21 July 2026 to 31 March 2027. Air-to-air heat pumps qualify for a smaller £2,500 grant.
MCS (Microgeneration Certification Scheme) certification means an installer has been independently assessed against UK quality standards for renewable heating installations. It's required both for installation quality assurance and to claim the Boiler Upgrade Scheme grant — only MCS-certified installers can apply it on your behalf. Use the MCS badge shown on listings here to check at a glance, or verify any installer directly at mcscertified.com. Read our full MCS certification guide →
The Boiler Upgrade Scheme offers £7,500 towards an air source or ground source heat pump in England and Wales, or £2,500 for an air-to-air heat pump. A temporary £9,000 grant applies to eligible off-gas-grid homes currently heated by oil or LPG, running from 21 July 2026 to 31 March 2027. The grant is deducted from your invoice upfront by your MCS-certified installer. Check your eligibility in 2 minutes →
Before any grant, a typical air source heat pump installation for a 3-4 bedroom home costs roughly £8,000–£14,000, including the unit, cylinder and any radiator upgrades. Ground source systems usually cost more due to the groundworks required for the ground loop. After the £7,500 Boiler Upgrade Scheme grant, many homeowners pay a net cost broadly comparable to a premium boiler replacement. See the full costs vs savings breakdown →
Most homes can install an air source heat pump under permitted development, without planning permission, provided it meets size and placement rules (such as being at least one metre from the property boundary). Listed buildings, conservation areas, and flats can have extra restrictions — check with your local planning authority or ask your installer to confirm before booking.
Yes, but insulation and radiator sizing matter more than with a gas boiler, since heat pumps run at lower flow temperatures. A good installer will assess your home's heat loss and may recommend larger radiators or improved insulation alongside the heat pump to keep it running efficiently.
A typical air source heat pump installation takes 2-3 days for a straightforward home. Ground source installations take longer due to the groundworks needed to lay the ground loop, sometimes a week or more depending on the method used.
Yes, but each nation runs a different scheme. England and Wales share the Boiler Upgrade Scheme (£7,500). Scotland has its own Home Energy Scotland Grant and Loan (up to £9,000 grant plus an optional £7,500 interest-free loan). Wales homeowners can also access the Nest scheme alongside BUS. Northern Ireland's support is smaller and means-tested, via the Affordable Warmth Scheme. See our full grants guide for links to apply for each.
Yes — from April 2026, the requirement to have no outstanding EPC insulation recommendations (such as loft or cavity wall insulation) was removed from the Boiler Upgrade Scheme in England and Wales. You still need a valid EPC (issued within the last 10 years), but outstanding insulation recommendations no longer block your application.
You don't apply directly — your MCS-certified installer applies on your behalf as part of quoting and booking your installation. The grant is issued as a voucher to your installer and deducted from your invoice, so you never handle the paperwork or payment yourself. Home Energy Scotland works differently: in Scotland, you apply directly before installation begins, rather than through your installer. See the full step-by-step walkthrough →
