Gas boiler to heat pump for Bexhill-on-Sea homes
A heat pump suits most Bexhill-on-Sea homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
If your Bexhill-on-Sea home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Semi-detached and terraced houses in Bexhill-on-Sea often have an airing cupboard that can be reused for a heat pump cylinder.
Moving from mains gas to a heat pump means finding cylinder space, deciding what happens to the gas supply and comparing running costs on realistic assumptions.
- Boilers that are old, unreliable or due for replacement
- Combi owners who can find space for a hot water cylinder
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Removal of the gas boiler, flue and any loft tanks
- Capping of the gas pipe at the boiler position where you are giving up gas
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- System flush and radiator upgrades where the design calls for them
- Heat pump cylinder, outdoor unit and weather compensation controls
Households across East Sussex moving off gas can have a survey in Bexhill-on-Sea that compares running costs on realistic assumptions.
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.

Replacing a gas boiler with a heat pump in Bexhill-on-Sea: questions
How soon can you survey a home in Bexhill-on-Sea?
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 Bexhill-on-Sea?
A home survey in Bexhill-on-Sea 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.
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.
Is there a grant to replace a gas boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump that replaces a gas boiler, for eligible owners of existing homes. The MCS-certified installer applies to Ofgem and deducts the grant from your quote, and Ofgem contacts you to confirm. Scotland has separate Home Energy Scotland funding, and Northern Ireland has no dedicated homeowner grant at present.
Do I need to replace the cylinder I already have?
Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.
