Before you book: replacing an oil or LPG boiler with a heat pump in Brighton
A heat pump suits most Brighton homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Owners across East Sussex can have oil tank removal arranged alongside a heat pump installation in Brighton. If your home near Brighton is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
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
- Eligible homes in England and Wales within the higher grant window
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- Help arranging LPG tank collection with your supplier
- MCS certificate and grant application in England and Wales where eligible
- Oil tank draining and removal or making safe, as set out in your quote
Bungalows and detached houses near Brighton 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 Brighton 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.

Designing for Brighton's winters
Brighton sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Replacing an oil or LPG boiler with a heat pump in Brighton: questions
Where would the outdoor unit go on a Brighton 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 Brighton home.
Do I need new radiators for a heat pump in Brighton?
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 Brighton home gives a room-by-room list.
Can you service a heat pump in Brighton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Brighton, whoever fitted them. Tell us the make and model when you book.
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.
