How we handle air source heat pumps in Hampstead Garden Suburb
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales and the installer makes the application. Not every home qualifies, so we check eligibility before you commit. The work covers air-to-water heat pumps, homes heated by oil, LPG or gas and underfloor heating, and common reasons people get in touch are no space for a hot water cylinder and choosing between air-to-water and air-to-air.
For flats in Hampstead Garden Suburb, 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.
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.

Common questions in Hampstead Garden Suburb
Can I fit a heat pump in Hampstead Garden Suburb without planning permission?
The answer turns on the property and where the outdoor unit would sit. The Hampstead Garden Suburb Conservation Area takes in the middle of Hampstead Garden Suburb. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Hampstead Garden Suburb, usually Barnet council).
Do I need permission to put air conditioning in my flat in Hampstead Garden Suburb?
Typically, yes, though leaseholders normally need the freeholder’s agreement. 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.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Does servicing affect my warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
Keeping the system healthy
How well a system lasts depends on use and care. We suggest:
- Keep up with insulation and draught-proofing
- Book a yearly service
- Keep the outdoor unit clear all year
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
Heat pumps in Hampstead Garden Suburb: local notes
About 39% of homes in and around Hampstead Garden Suburb were built before 1919, according to VOA council tax data. 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. For a London home, the outdoor unit position and the MCS noise check need careful planning.
A heat loss calculation decides the size of heat pump your home needs.

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. A unit used solely for cooling isn’t covered, so check with the council.
Hot water cylinders
An air-to-water heat pump heats hot water through a cylinder. Space for the cylinder is part of the survey, especially if you have a combi boiler.
What we do, step by step
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 anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. A note on parking and access helps us plan a visit to Hampstead Garden Suburb.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Let us know where we can park and unload
- Tell us about any building rules, permits or sign-in
- Arrange for someone to be there to let us in
