What to know about replacing a gas boiler with a heat pump in Bourne
A heat pump suits most Bourne homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Households across Lincolnshire moving off gas can have a survey in Bourne that compares running costs on realistic assumptions. Rear gardens and side returns in Bourne usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
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.
- System or regular boiler homes with an existing airing cupboard
- Boilers that are old, unreliable or due for replacement
- Combi owners who can find space for a hot water cylinder
What's included
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- System flush and radiator upgrades where the design calls for them
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Heat pump cylinder, outdoor unit and weather compensation controls
Many gas-heated homes in Bourne have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Bourne quote.
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.

Short winter days in Bourne and what they mean
Bourne has about 7 hours 36 minutes of daylight at midwinter and 16 hours 53 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Replacing a gas boiler with a heat pump in Bourne: questions
How long does installation take in Bourne?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Bourne home states the expected time.
How long does a heat pump survey take in Bourne?
A home survey in Bourne 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 Bourne 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 Bourne 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.
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.
