Before you book: replacing a gas boiler with a heat pump in Barnstaple
Every property in Barnstaple is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Many gas-heated homes in Barnstaple have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Households across Devon moving off gas can have a survey in Barnstaple that compares running costs on realistic assumptions.
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
- Combi owners who can find space for a hot water cylinder
- Boilers that are old, unreliable or due for replacement
What's included
- System flush and radiator upgrades where the design calls for them
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- Heat pump cylinder, outdoor unit and weather compensation controls
- Commissioning, MCS certificate and grant application in England and Wales where eligible
Semi-detached and terraced houses in Barnstaple often have an airing cupboard that can be reused for a heat pump 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 Barnstaple quote.
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.
Gas boiler to heat pump costs around Barnstaple
The ranges below are typical installed prices for homes in Devon, including VAT. A survey sets the exact figure, because two similar-looking houses in Barnstaple can need quite different radiators and pipework.

Designing for Barnstaple's winters
On the shortest day Barnstaple gets about 7 hours 54 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Replacing a gas boiler with a heat pump in Barnstaple: questions
How long does installation take in Barnstaple?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Barnstaple home states the expected time.
How soon can you survey a home in Barnstaple?
Survey dates depend on how busy installers are in Devon. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Bideford as well as Barnstaple?
Yes. We arrange surveys and installation in Bideford, which is about 8 miles south-west of Barnstaple, and across Devon.
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.
