Gas boiler to heat pump in Sidmouth: what to expect
Every property in Sidmouth 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.
Rear gardens and side returns in Sidmouth usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. If your Sidmouth 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.
- Households ready to give up gas entirely and drop the standing charge
- System or regular boiler homes with an existing airing cupboard
- Combi owners who can find space for a hot water cylinder
What's included
- Capping of the gas pipe at the boiler position where you are giving up gas
- 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
Households across Devon moving off gas can have a survey in Sidmouth that compares running costs on realistic assumptions.
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 Sidmouth 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.

Winter daylight and heating in Sidmouth
Sidmouth sees roughly 7 hours 58 minutes of daylight in late December against 16 hours 29 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Replacing a gas boiler with a heat pump in Sidmouth: questions
How long does installation take in Sidmouth?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Sidmouth home states the expected time.
How soon can you survey a home in Sidmouth?
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 I need new radiators for a heat pump in Sidmouth?
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 Sidmouth home gives a room-by-room list.
Will my hot water run out with a heat pump?
Not if the cylinder is sized properly for your household. The survey asks how many people live in the home, how many bathrooms you have and whether you prefer baths or showers, then sizes the cylinder to suit. The heat pump reheats the cylinder on a schedule, often overnight and again during the day, and an immersion heater acts as a backup.
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.
