Gas boiler to heat pump in Dartmouth: what to expect
In Dartmouth, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Rear gardens and side returns in Dartmouth usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Many gas-heated homes in Dartmouth have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder.
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
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
- Households ready to give up gas entirely and drop the standing charge
What's included
- Capping of the gas pipe at the boiler position where you are giving up gas
- System flush and radiator upgrades where the design calls for them
- Removal of the gas boiler, flue and any loft tanks
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Heat pump cylinder, outdoor unit and weather compensation controls
Households across Devon moving off gas can have a survey in Dartmouth that compares running costs on realistic assumptions.
Grants and rules for heat pumps in England
Homes in Dartmouth 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.
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.

How long is the heating season in Dartmouth?
Dartmouth sees roughly 8 hours 01 minutes of daylight in late December against 16 hours 26 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.

- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Replacing a gas boiler with a heat pump in Dartmouth: questions
Do I need new radiators for a heat pump in Dartmouth?
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 Dartmouth home gives a room-by-room list.
How long does a heat pump survey take in Dartmouth?
A home survey in Dartmouth 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.
Where would the outdoor unit go on a Dartmouth 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 Dartmouth home.
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.
Can a heat pump replace a combi boiler?
Yes, but you need room for a hot water cylinder, because heat pumps store hot water rather than heating it on demand. Most homes find a space in a cupboard, utility room, garage or under the stairs, and compact or combined indoor units help where space is tight. The survey measures the options first, so you know where everything will go before you accept the quote.
