Air conditioning installation in Cambridgeshire

Many village homes in the Fens and the rural north of Cambridgeshire have no mains gas and heat with oil or LPG. For a house like that, a split system that also cools is a heating decision first, and the summer comfort comes with it. The government publishes estimates of properties without a mains gas connection for each local authority area, if you want to see how common that is where you live [1]. In the city and the new estates around it, the question is usually the familiar summer one: a hot loft bedroom, a south-facing study, a new flat that will not cool down.

Who decides: five councils, and Peterborough on its own

Planning in Cambridgeshire is split between district councils, and it saves time to know which one is yours before you ask a conservation question:

• South Cambridgeshire: the villages ringing the city, plus Cambourne and Northstowe.
• Huntingdonshire: Huntingdon, St Ives, St Neots, Ramsey and Alconbury Weald.
• East Cambridgeshire: Ely, Soham, Littleport and the fen villages around them.
• Fenland: March, Wisbech, Whittlesey and Chatteris.
• Cambridge City: the city, covered in our Cambridge guide.

Peterborough sits inside the historic county but is a unitary authority with its own city council, so its planning questions go there.

Fen bungalows and the heating question

The villages between Ely, March and Chatteris have plenty of bungalows on decent plots, and bungalows are among the easiest homes to fit. Every room is on one floor, the loft gives a clean route for pipework to any of them, and there is nearly always room on the ground for a condenser. A single multi-split condenser feeding a wall unit in the living room and one in each of two bedrooms is a common shape, often fitted in two days.

The harder part is deciding what the system is for. A modern split is an air-to-air heat pump: in mild weather it delivers roughly three to four units of heat for each unit of electricity, but it cannot heat radiators or make hot water. For an oil-fired bungalow that leaves three routes: keep the boiler and use air-to-air to heat the main rooms most of the year (and cool them in summer); replace the boiler with an air-to-water heat pump for heating and hot water, which will not cool; or combine the two. Grant support treats the two kinds of heat pump differently, and only an MCS-certified installer can apply for you [2]. Our grant eligibility guide sets out the current position, and the planner's whole-home route compares the complete options side by side.

Two site details matter more on the open, windy Fens. In heating mode the outdoor unit defrosts itself on cold mornings and sheds water, so it should drain to gravel or a soakaway, not onto a path where it will freeze. And a condenser facing straight into the prevailing wind works harder and sounds louder, so a sheltered side of the house, or a low screen with plenty of clearance for airflow, is worth a few metres of extra pipe.

Huntingdon, St Ives and St Neots: the Ouse towns

The three Huntingdonshire towns share a pattern: a historic centre with a conservation area, Victorian and inter-war streets around it, and large modern estates on the edge, such as Loves Farm and Wintringham in St Neots. The estate houses are straightforward one-day jobs. In the older centres, conservation area and listed building rules decide where the condenser can go; the planning permission guide sets them out.

Riverside streets in all three towns, and in Godmanchester and the Hemingfords, include homes at risk of flooding from the Great Ouse. Check your address on the government's flood risk service before the survey [4], and if it shows a meaningful risk, ask for the condenser on a raised stand or wall brackets rather than a ground pad, with the electrics kept high.

Cambourne, Northstowe and the newer estates

Cambridgeshire has more planned new settlement than most counties: Cambourne, Northstowe, Alconbury Weald, and large extensions to most of the market towns. Only homes designed since Approved Document O came in during 2022 have had to be assessed for overheating [5]. Before booking a survey, check the planning permission for the estate itself: councils sometimes attach conditions that remove permitted development rights, and then an outdoor unit needs a planning application even where national rules would have allowed it. The new-build guide covers covenants and the rest.

Ely and Wisbech: the old centres

Ely has a large conservation area and many listed buildings near the cathedral. The outer streets of Ely and Wisbech are mostly terraces and semis that are easy to fit, but near the old centres the installation has to be designed around what can be seen from the street: a condenser on the rear elevation, pipework run inside, and for a listed building, consent before anything is drilled [3]. The period home guide covers the techniques.

What it costs

The cost guide has the national figures, and the cost estimator gives a first figure for your rooms. A bungalow multi-split tends to cost less than the same rooms spread over two floors because the pipe routes are short; listed or conservation-area work, raised flood-risk mounts and a new circuit back to the consumer unit push a quote up. The installer guide covers the F-gas checks.

Next step

Request an installer match with the rooms you want covered, whether you want heating as well as cooling, and a photo of where the outdoor unit might go. We'll review your requirements and match you with a suitable installer operating in your area.
