Before you book: replacing an oil or LPG boiler with a heat pump in Tavistock
Every property in Tavistock 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.
Owners across Devon can have oil tank removal arranged alongside a heat pump installation in Tavistock. If your home near Tavistock 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.
- Detached houses and bungalows with garden space for the unit
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
What's included
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- MCS certificate and grant application in England and Wales where eligible
- Help arranging LPG tank collection with your supplier
- Free survey with a detailed heat loss calculation for older construction
Rural properties near Tavistock usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Grants and rules for heat pumps in England
Homes in Tavistock 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.
Oil and LPG boiler replacement costs around Tavistock
The ranges below are typical installed prices for homes in Devon, including VAT. A survey sets the exact figure, because two similar-looking houses in Tavistock can need quite different radiators and pipework.

Replacing an oil or LPG boiler with a heat pump in Tavistock: questions
How long does a heat pump survey take in Tavistock?
A home survey in Tavistock 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 you cover Plymouth as well as Tavistock?
Yes. We arrange surveys and installation in Plymouth, which is about 12 miles south of Tavistock, and across Devon.
Can you service a heat pump in Tavistock that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tavistock, whoever fitted them. Tell us the make and model when you book.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
