Oil and LPG boiler replacement in Devon

We arrange air source heat pumps for homes throughout Devon, from the first heat loss survey to commissioning and annual servicing.

We plan the whole change: the heat pump, cylinder and radiators, and what happens to the tank. Oil tanks are drained, cleaned and removed or made safe, and leased LPG tanks are usually collected by the supplier that owns them. Your quote sets out which parts are included and who arranges each one, so nothing is left loose at the end.

If your home near Devon is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Rural properties near Devon usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Owners across Devon can have oil tank removal arranged alongside a heat pump installation in Devon.

Who it suits

  • Detached houses and bungalows with garden space for the unit
  • Rural and village homes off the mains gas grid
  • Older oil boilers nearing the end of their life
  • Owners tired of fuel deliveries and tank maintenance

Grants and rules for heat pumps in England

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 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.

Replacing an oil or LPG boiler with a heat pump questions

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.

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.

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.

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.
