Oil and LPG boiler replacement in Exeter: what to expect
Every property in Exeter 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 Exeter. Bungalows and detached houses near Exeter 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.
- Owners tired of fuel deliveries and tank maintenance
- Eligible homes in England and Wales within the higher grant window
- Older oil boilers nearing the end of their life
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Removal of the oil or LPG boiler and flue
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
If your home near Exeter is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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 Exeter quote.
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.

Short winter days in Exeter and what they mean
Exeter sees roughly 7 hours 57 minutes of daylight in late December against 16 hours 30 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Replacing an oil or LPG boiler with a heat pump in Exeter: questions
How long does installation take in Exeter?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Exeter home states the expected time.
How long does a heat pump survey take in Exeter?
A home survey in Exeter 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 Exeter?
Survey dates depend on how busy installers are in Devon. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
