Before you book: replacing an oil or LPG boiler with a heat pump in Barnstaple
Homes around Barnstaple range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Owners across Devon can have oil tank removal arranged alongside a heat pump installation in Barnstaple. If your home near Barnstaple is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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.
- Rural and village homes off the mains gas grid
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
What's included
- Removal of the oil or LPG boiler and flue
- Free survey with a detailed heat loss calculation for older construction
- Network operator notification and electrical connection
- Help arranging LPG tank collection with your supplier
- MCS certificate and grant application in England and Wales where eligible
Rural properties near Barnstaple usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
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 Barnstaple 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.

Replacing an oil or LPG boiler with a heat pump in Barnstaple: questions
How long does a heat pump survey take in Barnstaple?
A home survey in Barnstaple 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.
Do I need new radiators for a heat pump in Barnstaple?
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 Barnstaple home gives a room-by-room list.
What size heat pump does a Barnstaple 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 Barnstaple home.
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.
