Why these criteria
Cambridge homes test an installer’s design skills. The city is frostier than most of England, so the system must be sized for a colder design day. Much of the housing is solid-walled gault brick with suspended floors and sash windows. The water is very hard. Many streets are in conservation areas, and plenty of buildings are listed. The criteria below are aimed at finding installers who handle all of that well.
Required: MCS certification
MCS certifies renewable heating installers against standards for design, installation and commissioning. Since 28 April 2026, certification has been written into the Boiler Upgrade Scheme regulations, so the £7,500 grant depends on it. Certified installers must also belong to a consumer code — RECC or HIES — giving you protections on contracts, deposits and complaints.
Required: local presence
We look for installers who regularly work in Cambridge and the surrounding South Cambridgeshire villages, know Greater Cambridge Shared Planning, and can return for aftercare. A national firm that lists Cambridge on a coverage map isn’t the same thing.
Preferred: TrustMark
TrustMark is the government-endorsed scheme for tradespeople working in homes. It isn’t mandatory for heat pumps, but it’s a useful extra layer of standards.
Preferred: manufacturer approval
Approved-installer status with a manufacturer such as Mitsubishi Electric, Daikin, Vaillant or Grant generally means brand-specific training and sometimes longer warranties.
Preferred: design training
Specialist heat pump design training, such as the tiers recognised by Heat Geek, signals an installer who takes low-temperature design seriously — exactly what older Cambridge houses need.
What we won’t do
We don’t install or repair heat pumps, invent reviews, or send your details to several firms. One enquiry goes to one installer.
Tell us if standards slip
If an installer introduced through this site falls short, or their certification lapses, email privacy@cambridgeheatpumps.co.uk. We’ll pause enquiries to them while we check.
