Before you book: replacing an oil or LPG boiler with a heat pump in Heathfield
Most homes can run on a heat pump if the system is designed properly, and Heathfield is no different. The key is matching the heat pump and radiators to the home's heat loss.
Rural properties near Heathfield usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Owners across East Sussex can have oil tank removal arranged alongside a heat pump installation in Heathfield.
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
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Removal of the oil or LPG boiler and flue
- Oil tank draining and removal or making safe, as set out in your quote
- Help arranging LPG tank collection with your supplier
If your home near Heathfield 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 Heathfield 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 Heathfield: questions
Do you cover Uckfield as well as Heathfield?
Yes. We arrange surveys and installation in Uckfield, which is about 7 miles west of Heathfield, and across East Sussex.
Do I need new radiators for a heat pump in Heathfield?
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 Heathfield home gives a room-by-room list.
Where would the outdoor unit go on a Heathfield 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 Heathfield home.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
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.
