Oil and LPG boiler replacement means swapping a boiler that burns delivered fuel for an air-to-water heat pump running on electricity, then decommissioning the fuel tank. Homes off the gas grid are often rural, detached or older, so they tend to lose more heat than a typical suburban house. That makes careful heat loss design especially important, but it also means there is usually space outside for the unit.
If your home near Berkshire is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Rural properties near Berkshire usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. For homes outside Berkshire reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
Who it suits
- Eligible homes in England and Wales within the higher grant window
- Owners tired of fuel deliveries and tank maintenance
- Rural and village homes off the mains gas grid
- Older oil boilers nearing the end of their life
Grants and rules for heat pumps in England
Homes in Berkshire 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.

Replacing an oil or LPG boiler with a heat pump questions
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.
Can a heat pump cope with an exposed rural spot?
Yes. Air source heat pumps are designed to keep working well below freezing, and they periodically defrost, giving off a little vapour, which is normal. In exposed locations the installer chooses a sheltered position where possible, raises the unit to clear snow and let defrost water drain, and sizes the system for the local winter design temperature used in the heat loss calculation.
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.
