Before you book: replacing an oil or LPG boiler with a heat pump in Amersham
A heat pump suits most Amersham 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 Amersham 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 Amersham.
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
- Owners tired of fuel deliveries and tank maintenance
- Older oil boilers nearing the end of their life
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
- Network operator notification and electrical connection
- Removal of the oil or LPG boiler and flue
- Free survey with a detailed heat loss calculation for older construction
Rural properties near Amersham usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Grants and rules for heat pumps in England
Homes in Amersham 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.

How long is the heating season in Amersham?
On the shortest day Amersham gets about 7 hours 48 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Replacing an oil or LPG boiler with a heat pump in Amersham: questions
Can you service a heat pump in Amersham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Amersham, whoever fitted them. Tell us the make and model when you book.
Do you cover Chesham as well as Amersham?
Yes. We arrange surveys and installation in Chesham, which is about 2 miles north of Amersham, and across Buckinghamshire.
Do I need new radiators for a heat pump in Amersham?
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 Amersham home gives a room-by-room list.
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.
