Oil and LPG boiler replacement in Slough: what to expect
In Slough, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Owners across Berkshire can have oil tank removal arranged alongside a heat pump installation in Slough. Bungalows and detached houses near Slough running on LPG can move to a heat pump, with the tank collected by the supplier.
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.
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
- Eligible homes in England and Wales within the higher grant window
What's included
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
- Help arranging LPG tank collection with your supplier
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
If your home near Slough 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
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Slough quote.
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.
What to budget for replacing an oil or LPG boiler with a heat pump in Slough
These are guide prices for Berkshire, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

How long is the heating season in Slough?
On the shortest day Slough gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
The steps for replacing an oil or LPG boiler with a heat pump in Slough
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Slough; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Replacing an oil or LPG boiler with a heat pump in Slough: questions
How long does installation take in Slough?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Slough home states the expected time.
Can you service a heat pump in Slough that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Slough, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Slough?
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 Slough 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.
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.
