Air source heat pump installation in Bexhill-on-Sea: what to expect
Most homes can run on a heat pump if the system is designed properly, and Bexhill-on-Sea is no different. The key is matching the heat pump and radiators to the home's heat loss.
For older properties in Bexhill-on-Sea, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. In Bexhill-on-Sea, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
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.
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- MCS registration and certificate, plus network operator notification
- System design, unit sizing and a written quote
- Removal of the old boiler or heaters
- Commissioning, handover and a walk-through of the controls
Homeowners across East Sussex can arrange a survey in Bexhill-on-Sea for a room-by-room design and a written quote before committing to anything.
Grants and rules for heat pumps in England
Homes in Bexhill-on-Sea 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.
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.

Air source heat pump installation in Bexhill-on-Sea: questions
What size heat pump does a Bexhill-on-Sea home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Bexhill-on-Sea home.
Can you service a heat pump in Bexhill-on-Sea that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Bexhill-on-Sea, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Bexhill-on-Sea?
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 Bexhill-on-Sea home gives a room-by-room list.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
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.
