Before you book: air source heat pump installation in Wembley
Most homes can run on a heat pump if the system is designed properly, and Wembley is no different. The key is matching the heat pump and radiators to the home's heat loss.
Many homes in Wembley have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. For older properties in Wembley, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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.
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- Removal of the old boiler or heaters
- Commissioning, handover and a walk-through of the controls
- Radiator and pipework changes where the design needs them
- Outdoor unit, hot water cylinder and weather compensation controls
- MCS registration and certificate, plus network operator notification
Homeowners across Greater London can arrange a survey in Wembley for a room-by-room design and a written quote before committing to anything.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Wembley quote.
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.
Guide prices for air source heat pump installation in Wembley
The ranges below are typical installed prices for homes in Greater London, including VAT. A survey sets the exact figure, because two similar-looking houses in Wembley can need quite different radiators and pipework.

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning.
Winter daylight and heating in Wembley
On the shortest day Wembley 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 Wembley: questions
Do you cover Hendon as well as Wembley?
Yes. We arrange surveys and installation in Hendon, which is about 3 miles north-east of Wembley, and across Greater London.
Do I need new radiators for a heat pump in Wembley?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Wembley home gives a room-by-room list.
How long does installation take in Wembley?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Wembley 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.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
