How we handle air source heat pumps in West Hampstead
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; adding it alongside a boiler doesn’t qualify. We are often asked to deal with working out where a cylinder could go and radiators that may be too small for a heat pump, on hot water cylinders, underfloor heating and air-to-water heat pumps.
Terraced houses in a London area like West Hampstead can suit a heat pump well, provided the outdoor unit can sit somewhere that passes the MCS noise check.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Your questions about air source heat pumps in West Hampstead
Do I need permission to put air conditioning in my flat in West Hampstead?
Often, yes, but the lease and the freeholder usually have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Does the Boiler Upgrade Scheme cover homes in West Hampstead?
Yes, if the home and the heat pump meet the scheme’s rules: West Hampstead is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. We hold MCS certification, so the application is ours to make for you.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. For instance, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Common problems we fix in West Hampstead
For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
Most people get in touch after spotting something like this:
- Wanting to stop using oil, LPG or gas for heating
- An oil, LPG or gas boiler near the end of its life
- Working out whether radiators need upsizing
Period properties close to Presbyterian Church Of St Andrew can suit a heat pump, though insulation and any heritage protection are checked first.

- Exactly what the price includes, from supply and fitting to commissioning

What we do, step by step
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. The work itself takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the room and where the outdoor unit could go let us plan most of a visit to West Hampstead in advance.
- 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.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- 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
- Let us know if the building has a permit or sign-in process
- Mention any roof access, ladders or high-level work
Ask for a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

After we’ve gone
So the system stays in good health:
- Book a yearly service
- Check what your manufacturer’s warranty asks of you
- Leave space around the outdoor unit
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork for future reference.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on so keep it unobstructed.
What a heat pump looks like in West Hampstead
About 63% of homes in West Hampstead and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and the 2021 Census found about 82% 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. 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.
For a home near Finchley Road & Frognal station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.
