What to know about replacing an oil or LPG boiler with a heat pump in Cranleigh
A heat pump suits most Cranleigh homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For homes outside Cranleigh reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Bungalows and detached houses near Cranleigh running on LPG can move to a heat pump, with the tank collected by the supplier.
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.
- Eligible homes in England and Wales within the higher grant window
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
- Free survey with a detailed heat loss calculation for older construction
- Removal of the oil or LPG boiler and flue
- Network operator notification and electrical connection
Cottages and farmhouses in and around Cranleigh often have solid walls, so the survey looks closely at construction and draughts.
Grants and rules for heat pumps in England
Homes in Cranleigh 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.

Designing for Cranleigh's winters
On the shortest day Cranleigh gets about 7 hours 53 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.

Replacing an oil or LPG boiler with a heat pump in Cranleigh: questions
How long does installation take in Cranleigh?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Cranleigh home states the expected time.
What size heat pump does a Cranleigh 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 Cranleigh home.
How long does a heat pump survey take in Cranleigh?
A home survey in Cranleigh 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.
Do I have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
