What to know about air source heat pump installation in West Hampstead
Homes around West Hampstead range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Homeowners across Greater London can arrange a survey in West Hampstead for a room-by-room design and a written quote before committing to anything. Many homes in West Hampstead have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Households with room for a hot water cylinder
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- MCS registration and certificate, plus network operator notification
- Removal of the old boiler or heaters
- Boiler Upgrade Scheme application in England and Wales where eligible
- Commissioning, handover and a walk-through of the controls
Installers working in West Hampstead plan the order of work so heating and hot water are off for as short a time as practical.
Grants and rules for heat pumps in England
Homes in West Hampstead can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

How long is the heating season in West Hampstead?
On the shortest day West Hampstead gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Air source heat pump installation in West Hampstead: questions
How soon can you survey a home in West Hampstead?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a West Hampstead home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your West Hampstead home.
How long does installation take in West Hampstead?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a West Hampstead home states the expected time.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
