Air source heat pumps for homes and businesses in London
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. Typical jobs include comparing heat pump types and working out where a cylinder could go, on underfloor heating, air-to-water heat pumps and air-to-air heat pumps.
Homes in London range from older houses to new builds, and that matters for a heat pump. Every design starts with a room-by-room heat loss calculation, so it’s sized properly.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

London: your questions answered
Do I need permission to put air conditioning in my flat in London?
In many cases, yes, once the lease and the building’s rules are checked. 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 London?
London is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Can you come out in an emergency?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Should I choose air-to-water or air-to-air?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling, and we help you choose. Both are part of what we install.
What does an air-to-water heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales, and we confirm eligibility before you commit.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.

After we have gone
Looking after it is simple, and it helps at the next service:
- Keep to regular servicing
- Check what your manufacturer’s warranty asks of you
- Keep the outdoor unit clear all year
The warranty on the heat pump is the manufacturer’s, on its own terms. We explain the terms for your brand, including any servicing conditions.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside so keep it unobstructed.
Rented and managed buildings
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Facilities teams in offices, schools and public buildings book us too across Greater London. Work can be phased by floor, zone or building around the people who use them.
How the visit works
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. For businesses, we can normally work room by room or zone by zone. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Work at a business in London can be split over a few visits so you keep trading.
- First we find out about the property, the heating you have now and what you’re hoping for.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any managing agent or landlord rules we need to follow
- Tell us about access, such as roof hatches, high walls or locked plant areas

Every quote shows the VAT clearly, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, phone us on 07833 053749 or email us.

Air source heat pumps around London
About 48% of homes in London and the neighbourhoods around it have been built since 2000, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 93% of households live in flats. Newer homes usually lose less heat, which tends to suit a heat pump well. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Mansion House lies about 1 mile north. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions. Period properties close to St George the Martyr can suit a heat pump, though insulation and any heritage protection are checked first.
