Air source heat pumps around Southfields
VOA council tax data put about 57% of homes in and around Southfields before 1919, and Census 2021 figures found about 62% of households live in flats. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
For a home near Earlsfield station, the survey looks at whether an air-to-water or air-to-air heat pump suits better. If your home is listed, like Fulham Palace about 1.9 miles north-west, listed building consent comes before any heat pump work.

Air source heat pumps for homes and businesses in Southfields
As an MCS certified installer, we fit air source heat pumps for homes in Southfields 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. Typical jobs include an oil, LPG or gas boiler near the end of its life and questions about where the outdoor unit can go, across air-to-water heat pumps, hot water cylinders and air-to-air heat pumps.
A terrace in Southfields shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

What else we do in Southfields
After we’ve gone
Looking after it is simple, and it makes the next visit easier:
- Check what your manufacturer’s warranty asks of you
- Keep radiators clear
- Keep up with insulation and draught-proofing
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Do not cover radiators with furniture or heavy curtains so the heat can get into the room.
How the visit works
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Send us a few phone pictures and we can often price a straightforward job in Southfields before visiting.
- It starts with a conversation about the home, the existing heating and your plans.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
How to prepare
- Tell us about parking and loading
- Let us know if the units are on a roof, a high wall or in a locked area
- Dig out any previous service or F-Gas records

What owners can safely do
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
Southfields: your questions answered
Can I get the Boiler Upgrade Scheme grant in Southfields?
Yes, if the home and the heat pump meet the scheme’s rules: Southfields is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You don’t apply yourself: the MCS certified installer does, which is us.
Can you fit air conditioning in a London flat in Southfields?
Often, yes, but the lease and the freeholder normally 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.
How long does a heat pump installation take?
An installation takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. We confirm the timing after the survey, so ring us on 07833 053749, or email if that’s easier to arrange one.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us in Southfields and across Greater London. Tell us who should receive the paperwork.
Is Southfields in your area?
Yes. We cover Southfields and the rest of Greater London, within the London and South East area we cover. For a fixed-price quote, ring 07833 053749 or email us.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Does servicing affect my warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them and stick to the interval they set.
What the work involves, system by system
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included, so check with the council.
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, so radiator sizes matter.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
