Heat Pump Installers Cambridge: MCS and Grants

Heat pumps work across the UK climate, so the weather is rarely what holds a Cambridge project back. What decides the job more often is the house type: semis in the suburbs are easy, while flats and some older terraces need more thought.

Cambridge at a glance

Homes that are flats: 35.0% of Cambridge households lived in a flat in 2021, most of them (30.7%) in purpose-built blocks. Source
How homes are heated: 75.1% of Cambridge households heat with mains gas only, 11.6% with electricity only and 2.1% (1,096 homes) from a district or communal heat network. Oil alone heats just 97 homes. Source
Local grant: Cambridge City Council leads the Cambridgeshire Energy Retrofit Partnership, which won £8.5 million of Warm Homes: Local Grant funding for low-income homes across Cambridgeshire and Peterborough. Eligibility details are on the Action on Energy website. Source
Energy ratings: About 34% of homes with an EPC in Cambridge are rated band D or below (median score 73, band C), against 47% across England. Based on certificates lodged in the 10 years to March 2025. Source

Suburban semis

Semis in Chesterton, Arbury and Cherry Hinton usually have a side passage or garden for the unit and cavity walls that can be filled. Get insulation done before the heat loss survey so the system is not oversized.

A single air source unit on a house is usually permitted development if it meets MCS noise limits. In a conservation area it cannot face the road, and listed buildings need consent.

Flats and heat networks

35% of Cambridge households live in flats, where outdoor space and freeholder consent are the main hurdles. 2.1% of homes already get heat from a district or communal network, and switching those to individual heat pumps is a decision for the building owner.

Air-to-air heat pumps can work in flats where a cylinder will not fit. The grant for those is £2,500.

Funding

For a Cambridge home, the Boiler Upgrade Scheme gives £7,500 off an air or ground source heat pump. There is no income test.

Cambridge City Council leads a partnership that won £8.5 million of Warm Homes: Local Grant funding for low-income homes in Cambridgeshire, which can include air source heat pumps. Check eligibility on the Action on Energy website.

Cambridge homes and what they need

Victorian gault brick and red brick terraces

Solid walls and small back yards make these harder. A compact unit in the yard and internal insulation on the coldest walls can make it work.

Interwar and post-war semis in the northern and eastern suburbs

The best fit in Cambridge. Expect a few radiators to be upsized and a cylinder in the old airing cupboard.

Recent developments on the city fringes

Low heat loss means a small heat pump can do the job. Some developments were built with heat pumps or communal heating already.

Areas covered

Engineers who cover Cambridge work across areas including Chesterton, Romsey, Cherry Hinton, Trumpington, Arbury, Newnham, Histon, Girton, Great Shelford and Milton.

Questions people in Cambridge ask

Does very hard water affect a heat pump?

The heating circuit is sealed, so scale is not a big issue there. The hot water cylinder still faces scale, so ask about protection on the cold feed.

What does it cost?

See our heat pump cost guide for prices before and after the grant, and our air source heat pumps guide for running costs.
