Before you book: air source heat pump installation in Ruislip
Every property in Ruislip is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Homeowners across Greater London can arrange a survey in Ruislip for a room-by-room design and a written quote before committing to anything. Many homes in Ruislip 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.
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
What's included
- Commissioning, handover and a walk-through of the controls
- Boiler Upgrade Scheme application in England and Wales where eligible
- Outdoor unit, hot water cylinder and weather compensation controls
- Free home survey and room-by-room heat loss calculation
- Radiator and pipework changes where the design needs them
Installers working in Ruislip 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 Ruislip 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.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

On the shortest day Ruislip 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 Ruislip: questions
How long does installation take in Ruislip?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Ruislip home states the expected time.
Do I need new radiators for a heat pump in Ruislip?
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 Ruislip home gives a room-by-room list.
Can you service a heat pump in Ruislip that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Ruislip, whoever fitted them. Tell us the make and model when you book.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
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.
