What to know about replacing a gas boiler with a heat pump in Godalming
Every property in Godalming 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.
Installers in Godalming take out the old boiler and flue and seal the wall opening as part of the job. If your Godalming home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.
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.
- Boilers that are old, unreliable or due for replacement
- 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
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Free survey with heat loss calculation and cylinder siting
- System flush and radiator upgrades where the design calls for them
- Removal of the gas boiler, flue and any loft tanks
Households across Surrey moving off gas can have a survey in Godalming that compares running costs on realistic assumptions.
Grants and rules for heat pumps in England
Homes in Godalming 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 Godalming: questions
How long does a heat pump survey take in Godalming?
A home survey in Godalming 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.
Do you cover Guildford as well as Godalming?
Yes. We arrange surveys and installation in Guildford, which is about 4 miles north-east of Godalming, and across Surrey.
Where would the outdoor unit go on a Godalming 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 Godalming 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.
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.
