Air source heat pumps for homes and businesses in St John's Wood
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. If you’re dealing with finding a place for the outdoor unit and deciding which kind of heat pump suits the home, we can sort it out.
In a flat in St John's Wood, the lease and the freeholder normally decide where a heat pump can go. The planning rules for flats are stricter than for houses, and we check before designing.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Do you need air source heat pumps in St John's Wood?
People also ask about air-to-air heat pumps because they heat and cool. They heat rooms through wall, floor or ceiling units, and can cool them when it’s hot. The grant only applies in some cases, so we check first.
Most people get in touch when they notice one of these:
- Questions about the Boiler Upgrade Scheme
- Questions about where the outdoor unit can go
- Working out where a cylinder could go
With Winfield House about 0.6 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump.

How the visit works
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. A few pictures of the room, the outside wall and the fuse board help us plan a job in St John's Wood.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Have the make and model of any existing unit to hand
- Make sure we can reach the consumer unit or fuse board
- Arrange for someone to be there to let us in

What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and give us a ring on 07833 053749 or drop us a line.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
What air conditioning won’t do
A few issues sit outside what this work can do:
- A grant for a home that does not meet the scheme rules
- Getting planning permission or listed building consent on your behalf
- Insulation work, such as loft or cavity wall insulation
Not sure which it is? You can give us a ring on 07833 053749 or drop us a line and we will tell you honestly.
Parts of the system we cover
- Air-to-water heat pumps
- Homes heated by oil, LPG or gas
- Hot water cylinders
- Air-to-air heat pumps
- Radiator systems
- Underfloor heating
St John's Wood: your questions answered
Can you fit air conditioning in a London flat in St John's Wood?
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.
Does the Boiler Upgrade Scheme cover homes in St John's Wood?
Yes, if the home and the heat pump meet the scheme’s rules: St John's Wood is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Do you look at the job first?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
How much does an air source heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Why does F-Gas certification matter?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
Which manufacturers do you install and repair?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.

Air source heat pumps around St John's Wood
About 88% of households live in flats, according to the 2021 Census. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit. For a London home, the outdoor unit position and the MCS noise check need careful planning.
