Gas boiler to heat pump for Southport homes
A heat pump suits most Southport homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Households across Merseyside moving off gas can have a survey in Southport that compares running costs on realistic assumptions. Installers in Southport 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.
- 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
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Free survey with heat loss calculation and cylinder siting
- 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
- System flush and radiator upgrades where the design calls for them
Rear gardens and side returns in Southport usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
Grants and rules for heat pumps in England
Homes in Southport 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.
What to budget for replacing a gas boiler with a heat pump in Southport
These are guide prices for Merseyside, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,200–£12,150 | £1,700–£4,650 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,200–£13,100 | £2,700–£5,600 |

How long is the heating season in Southport?
On the shortest day Southport gets only about 7 hours 26 minutes of daylight and the noon sun sits around 13° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.

Replacing a gas boiler with a heat pump in Southport: questions
Can you service a heat pump in Southport that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Southport, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Southport?
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 Southport home gives a room-by-room list.
Where would the outdoor unit go on a Southport 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 Southport home.
Do I need to replace the cylinder I already have?
Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.
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.
