Gas boiler to heat pump for Felixstowe homes
Homes around Felixstowe range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Many gas-heated homes in Felixstowe have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Installers in Felixstowe 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
- Households ready to give up gas entirely and drop the standing charge
- System or regular boiler homes with an existing airing cupboard
What's included
- Heat pump cylinder, outdoor unit and weather compensation controls
- System flush and radiator upgrades where the design calls for them
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
Semi-detached and terraced houses in Felixstowe often have an airing cupboard that can be reused for a heat pump cylinder.
Grants and rules for heat pumps in England
Homes in Felixstowe 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.
Guide prices for replacing a gas boiler with a heat pump in Felixstowe

Short winter days in Felixstowe and what they mean
Felixstowe has about 7 hours 45 minutes of daylight at midwinter and 16 hours 44 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 Felixstowe: questions
How long does installation take in Felixstowe?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Felixstowe home states the expected time.
How soon can you survey a home in Felixstowe?
Survey dates depend on how busy installers are in Suffolk. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Harwich as well as Felixstowe?
Yes. We arrange surveys and installation in Harwich, which is about 3 miles south-west of Felixstowe, and across Suffolk.
What if my gas boiler is fairly new?
A newer boiler can still be replaced, but the timing is worth weighing. Some owners switch when the boiler needs a major repair; others prefer to plan the change for a convenient time. Across the UK, heat pump installation is zero-rated for VAT until 31 March 2027. A hybrid system, which keeps the boiler alongside a heat pump, is another option, though it is not eligible for the Boiler Upgrade Scheme in England and Wales.
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.
