Before you book: replacing a gas boiler with a heat pump in Battle
The question for a Battle home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Many gas-heated homes in Battle have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Semi-detached and terraced houses in Battle 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.
- Households ready to give up gas entirely and drop the standing charge
- System or regular boiler homes with an existing airing cupboard
- Combi owners who can find space for a hot water cylinder
What's included
- System flush and radiator upgrades where the design calls for them
- Capping of the gas pipe at the boiler position where you are giving up gas
- Heat pump cylinder, outdoor unit and weather compensation controls
- Free survey with heat loss calculation and cylinder siting
- Removal of the gas boiler, flue and any loft tanks
Households across East Sussex moving off gas can have a survey in Battle that compares running costs on realistic assumptions.
Grants and rules for heat pumps in England
Homes in Battle 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.

Replacing a gas boiler with a heat pump in Battle: questions
Can you service a heat pump in Battle that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Battle, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Battle?
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.
Where would the outdoor unit go on a Battle 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 Battle home.
Will my hot water run out with a heat pump?
Not if the cylinder is sized properly for your household. The survey asks how many people live in the home, how many bathrooms you have and whether you prefer baths or showers, then sizes the cylinder to suit. The heat pump reheats the cylinder on a schedule, often overnight and again during the day, and an immersion heater acts as a backup.
Should I have my gas meter removed?
If gas is used for nothing else, removing the meter ends the gas standing charge, which is about £108 a year at the October to December 2026 price cap. If you still cook on gas or have a gas fire, you will need to keep the supply. Meter removal is arranged through your gas supplier, usually once the heat pump is running; the pipe at the boiler position is capped during the installation.
