About our air source heat pumps in Northfields
As an MCS certified installer, we fit air source heat pumps for homes in Northfields and the rest of Greater London. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We will explain which type fits your home and why. The work covers air-to-air heat pumps, hot water cylinders and underfloor heating, and the jobs we see most are ageing boilers that will need replacing and questions about where the outdoor unit can go.
Terraced houses in a London area like Northfields can suit a heat pump well, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

How the job changes from property to property
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It replaces the boiler as the main heat source, and is MCS certified when we install it.
Heat loss surveys
A heat loss survey measures how much heat each room loses on a cold day. Everything else is sized from it.
Let and managed properties
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side and send the records to whoever needs them.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.
Northfields: your questions answered
Is a heat pump in Northfields permitted development?
It depends on the property. Historic England lists about 13 buildings and structures within half a mile of the centre of Northfields. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the planning department at Ealing council, normally the authority for Northfields.
Can you fit air conditioning in a London flat in Northfields?
Often, yes, but the lease and the freeholder typically have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do you work in Northfields?
Yes. Our engineers work in Northfields, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
Can I get a grant for an air-to-air heat pump?
The scheme offers £2,500 for air-to-air, but the conditions are strict. It will not apply if the system is an add-on next to a boiler, and it must cover the whole heating demand.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
How soon will you get back to me?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Do I need new radiators for a heat pump?
It depends on each radiator and the room it heats. At the lower temperatures a heat pump uses, radiators need more surface, and the survey checks each one.
What we do, step by step
The first job on site is protection: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes several days for an air-to-water system with a new cylinder, less for an air-to-air system, and we tidy up before we leave. Photos of the room and where the outdoor unit could go let us plan most of a visit to Northfields in advance.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Arrange for someone to be there to let us in
- Mention any managing agent or landlord rules we need to follow

Air source heat pumps around Northfields
About 63% of homes in Northfields and the neighbourhoods around it were built before 1919, according to VOA council tax data, and the last census (2021) found about 36% of households in terraced houses. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
If your home is near Brentford station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. If your home is listed, like Boston Manor about 0.5 miles south, listed building consent comes before any heat pump work.
