Oil and LPG boiler replacement for Buckingham homes
A heat pump suits most Buckingham homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For homes outside Buckingham reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Cottages and farmhouses in and around Buckingham often have solid walls, so the survey looks closely at construction and draughts.
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
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- Free survey with a detailed heat loss calculation for older construction
Bungalows and detached houses near Buckingham running on LPG can move to a heat pump, with the tank collected by the supplier.
Grants and rules for heat pumps in England
Homes in Buckingham 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 in Buckingham: questions
Can you service a heat pump in Buckingham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Buckingham, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Buckingham 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 Buckingham home.
How long does installation take in Buckingham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Buckingham home states the expected time.
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.
