Before you book: air source heat pump installation in Hastings
In Hastings, 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.
Installers working in Hastings plan the order of work so heating and hot water are off for as short a time as practical. Terraced streets in Hastings 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 who want one contract covering design, fitting and paperwork
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it
What's included
- Removal of the old boiler or heaters
- Outdoor unit, hot water cylinder and weather compensation controls
- Radiator and pipework changes where the design needs them
- Free home survey and room-by-room heat loss calculation
- Commissioning, handover and a walk-through of the controls
Many homes in Hastings have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
Grants and rules for heat pumps in England
Homes in Hastings 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.
What to budget for air source heat pump installation in Hastings
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 Hastings?
On the shortest day Hastings 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 Hastings: questions
How soon can you survey a home in Hastings?
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 a heat pump survey take in Hastings?
A home survey in Hastings 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.
Where would the outdoor unit go on a Hastings 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 Hastings home.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
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.
