What to know about replacing a gas boiler with a heat pump in Market Harborough
Most homes can run on a heat pump if the system is designed properly, and Market Harborough is no different. The key is matching the heat pump and radiators to the home's heat loss.
Many gas-heated homes in Market Harborough have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Installers in Market Harborough take out the old boiler and flue and seal the wall opening as part of the job.
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.
- Combi owners who can find space for a hot water cylinder
- System or regular boiler homes with an existing airing cupboard
- Boilers that are old, unreliable or due for replacement
What's included
- Free survey with heat loss calculation and cylinder siting
- Removal of the gas boiler, flue and any loft tanks
- Heat pump cylinder, outdoor unit and weather compensation controls

Households across Leicestershire moving off gas can have a survey in Market Harborough that compares running costs on realistic assumptions.
Grants and rules for heat pumps in England
Homes in Market Harborough 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 Market Harborough: questions
Do I need new radiators for a heat pump in Market Harborough?
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 Market Harborough home gives a room-by-room list.
How long does a heat pump survey take in Market Harborough?
A home survey in Market Harborough 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 Market Harborough 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 Market Harborough 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.
