Homes in Mayfair and heat pumps
Valuation Office Agency council tax records put about 51% of homes in and around Mayfair before 1919, and the last census (2021) found about 93% of households live in flats. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Homeowners near Bond Street station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that. Older homes near Grosvenor Chapel may need extra checks for planning and heat loss before a heat pump is designed.
Mayfair is about 1 mile south-east of City of Westminster, in Greater London. Our engineers cover Mayfair for air source heat pumps, along with the rest of Greater London. Our area takes in 764 places across Greater London.
The closest recent job we can point to from Mayfair was on East Hill, Wandsworth (SW18), about 4 miles south-west: installing a Daikin wall-mounted unit in the open-plan living area.
You’ll find Mayfair on the A4201 and A4202, which makes it straightforward for our engineers to reach for surveys and visits.

How we handle air source heat pumps in Mayfair
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. The work covers underfloor heating, air-to-water heat pumps and radiator systems, and people most often call us about ageing boilers that will need replacing and not knowing whether a grant applies.
In a flat in Mayfair, the lease and the freeholder usually decide where a heat pump can go. Permitted development limits are different for flats, and we check before designing.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Pricing air source heat pumps in Mayfair
The price is fixed before any work begins. It takes into account:
- The brand, model and parts involved
- What kind of system it is
- A single visit or a regular plan
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we will talk you through it.
Asking for a quote
Before you ask for a quote, gather:
- The remote or wall controller showing any error
- The paperwork from the last service, if you have it
- Photos showing the indoor unit and the space around it
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price before any work starts.
What we do, step by step
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, do the work, check the system and explain it all to you. On site, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. A note on parking and access helps us plan a visit to Mayfair.
- First we find out about the property, the heating you have now and what you are hoping for.
- 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.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Dig out any previous service or F-Gas records
- Plan for pets to be kept clear during the visit
- Tell us about any building rules, permits or sign-in
Get a fixed-price quote
Getting a quote is straightforward. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
Advice
Mayfair: your questions answered
Do I need permission to put air conditioning in my flat in Mayfair?
Often, yes, but the lease and the freeholder usually 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.
Is the heat pump grant available in Mayfair?
Yes, if the home and the heat pump meet the scheme’s rules: Mayfair is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we are MCS certified.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for example, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
What’s the price of a heat pump installation?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme though not every home qualifies.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Honest limits
We’d rather tell you now than sell you work that won’t help, so these are the things it won’t cover:
- Grants for hybrid systems or replacements of low-carbon systems
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Tax advice on your own circumstances
Not sure which it is? You can call 07833 053749 and we will tell you honestly before booking.
Where we work

Rented and managed buildings
We regularly work with managing agents. Tell us the property, the work and the access arrangements, and we’ll send a fixed-price quote.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
