Heat pump installation in South Hampstead, Greater London
Our engineers work in South Hampstead on MCS certified installation of air source heat pumps for heating and hot water, with the Boiler Upgrade Scheme grant applied for. A look at the job first, a fixed-price quote and written records at the end.
- Wanting to stop using oil, LPG or gas for heating
- Replacing a combi boiler with a heat pump
- Finding a place for the outdoor unit
Keeping the system healthy
To keep the system working properly:
- Know the servicing conditions in your warranty
- Do not block radiators or indoor units with furniture
- Keep to regular servicing
Now and then in cold weather, the outdoor unit defrosts itself. You might see steam or hear the unit change note, and that’s normal.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside, so keep it clear all year.
About our air source heat pumps in South Hampstead
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. We’re often asked to deal with checking whether planning permission is needed and questions about where the outdoor unit can go, across homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps.
For flats in South Hampstead, the lease, the freeholder and the rules for flats all come into it. The planning rules for flats are stricter than for houses, and we check before designing.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

FAQs for South Hampstead
Do I need planning permission for a heat pump in South Hampstead?
It comes down to the building and the spot chosen for the outdoor unit. The Belsize Park Conservation Area is close to the centre of South Hampstead. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Camden council, which is typically the planning authority for South Hampstead.
Can I get the Boiler Upgrade Scheme grant in South Hampstead?
Yes, if the home and the heat pump meet the scheme’s rules: South Hampstead 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. We hold MCS certification, so the application is ours to make for you.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
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.
Heat pumps in South Hampstead: local notes
About 47% of homes in the South Hampstead area were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 90% of households live in flats, according to Census 2021 figures. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. 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.
Winfield House, roughly 0.9 miles south-east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings. If your home is near South Hampstead station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.
