Before you book: air source heat pump installation in Wimbledon
Homes around Wimbledon range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Installers working in Wimbledon plan the order of work so heating and hot water are off for as short a time as practical. Terraced streets in Wimbledon often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
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.
- Houses with reasonable insulation, or a plan to improve it
- Homes replacing a gas, oil, LPG or electric heating system
- Households with room for a hot water cylinder
What's included
- Free home survey and room-by-room heat loss calculation
- Outdoor unit, hot water cylinder and weather compensation controls
- Removal of the old boiler or heaters
- Boiler Upgrade Scheme application in England and Wales where eligible
- System design, unit sizing and a written quote
In Wimbledon, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in England
Homes in Wimbledon 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.
What to budget for air source heat pump installation in Wimbledon
Guide prices for Wimbledon and the rest of Greater London are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.

How long is the heating season in Wimbledon?
On the shortest day Wimbledon gets about 7 hours 50 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 Wimbledon: questions
How long does a heat pump survey take in Wimbledon?
A home survey in Wimbledon usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How soon can you survey a home in Wimbledon?
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.
Do I need new radiators for a heat pump in Wimbledon?
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 Wimbledon home gives a room-by-room list.
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.
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.
