Before you book: replacing an oil or LPG boiler with a heat pump in Bletchley
A heat pump suits most Bletchley homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Bungalows and detached houses near Bletchley running on LPG can move to a heat pump, with the tank collected by the supplier. Owners across Buckinghamshire can have oil tank removal arranged alongside a heat pump installation in Bletchley.
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
- Detached houses and bungalows with garden space for the unit
- Older oil boilers nearing the end of their life
What's included
- MCS certificate and grant application in England and Wales where eligible
- Removal of the oil or LPG boiler and flue
- Free survey with a detailed heat loss calculation for older construction
- Oil tank draining and removal or making safe, as set out in your quote
- Outdoor unit, heat pump cylinder, controls and radiator changes
If your home near Bletchley 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
Homes in Bletchley 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 Bletchley: questions
Do I need new radiators for a heat pump in Bletchley?
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 Bletchley home gives a room-by-room list.
How soon can you survey a home in Bletchley?
Survey dates depend on how busy installers are in Buckinghamshire. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Bletchley 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 Bletchley home.
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.
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.
