Before you book: air source heat pump installation 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.
For older properties in Hailsham, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Terraced streets in Hailsham often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
- Commissioning, handover and a walk-through of the controls
- Removal of the old boiler or heaters
Installers working in Hailsham plan the order of work so heating and hot water are off for as short a time as practical.
Grants and rules for heat pumps in England
Homes in Hailsham 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.

These are guide prices for East Sussex, 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 Hailsham?
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.

Air source heat pump installation in Hailsham: questions
How soon can you survey a home in Hailsham?
Survey dates depend on how busy installers are in East Sussex. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Hailsham?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Hailsham home states the expected time.
Where would the outdoor unit go on a Hailsham 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 Hailsham home.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
