Before you book: replacing an oil or LPG boiler with a heat pump in Biggleswade
Every property in Biggleswade 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 Bedfordshire can have oil tank removal arranged alongside a heat pump installation in Biggleswade. For homes outside Biggleswade reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
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.
- Older oil boilers nearing the end of their life
- Owners tired of fuel deliveries and tank maintenance
- Rural and village homes off the mains gas grid
What's included
- Network operator notification and electrical connection
- Oil tank draining and removal or making safe, as set out in your quote
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Help arranging LPG tank collection with your supplier
- Removal of the oil or LPG boiler and flue
Bungalows and detached houses near Biggleswade 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 Biggleswade 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Replacing an oil or LPG boiler with a heat pump in Biggleswade: questions
Do I need new radiators for a heat pump in Biggleswade?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Biggleswade home gives a room-by-room list.
Where would the outdoor unit go on a Biggleswade house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Biggleswade home.
How long does a heat pump survey take in Biggleswade?
A home survey in Biggleswade 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.
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.
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.
