Before you book: replacing an oil or LPG boiler with a heat pump in Hailsham
In Hailsham, 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.
Bungalows and detached houses near Hailsham running on LPG can move to a heat pump, with the tank collected by the supplier. Cottages and farmhouses in and around Hailsham often have solid walls, so the survey looks closely at construction and draughts.
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
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- MCS certificate and grant application in England and Wales where eligible
- Network operator notification and electrical connection
- Free survey with a detailed heat loss calculation for older construction
- Removal of the oil or LPG boiler and flue
Rural properties near Hailsham usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
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 Hailsham quote.
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.
Guide prices for replacing an oil or LPG boiler with a heat pump in Hailsham
The ranges below are typical installed prices for homes in East Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in Hailsham can need quite different radiators and pipework.

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. The £9,000 Boiler Upgrade Scheme figure applies to oil and LPG replacements in England and Wales installed from 21 July 2026 to 31 March 2027.
Designing for Hailsham's winters
On the shortest day Hailsham gets about 7 hours 56 minutes of daylight, and the winter sun reaches only around 16° 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.

Replacing an oil or LPG boiler with a heat pump in Hailsham: questions
Can you service a heat pump in Hailsham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hailsham, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Hailsham?
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 Hailsham home gives a room-by-room list.
How long does a heat pump survey take in Hailsham?
A home survey in Hailsham usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
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.
