What to know about replacing an oil or LPG boiler with a heat pump in Crowthorne
Homes around Crowthorne range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Owners across Berkshire can have oil tank removal arranged alongside a heat pump installation in Crowthorne. Rural properties near Crowthorne usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Older oil boilers nearing the end of their life
- Eligible homes in England and Wales within the higher grant window
- Owners tired of fuel deliveries and tank maintenance
What's included
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
Cottages and farmhouses in and around Crowthorne often have solid walls, so the survey looks closely at construction and draughts.
Grants and rules for heat pumps in England
Homes in Crowthorne 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.

Replacing an oil or LPG boiler with a heat pump in Crowthorne: questions
Where would the outdoor unit go on a Crowthorne house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Crowthorne home.
Do I need new radiators for a heat pump in Crowthorne?
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 Crowthorne home gives a room-by-room list.
How long does a heat pump survey take in Crowthorne?
A home survey in Crowthorne 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 much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
