Gas boiler to heat pump in Gosport: what to expect
Most homes can run on a heat pump if the system is designed properly, and Gosport is no different. The key is matching the heat pump and radiators to the home's heat loss.
Households across Hampshire moving off gas can have a survey in Gosport that compares running costs on realistic assumptions. Many gas-heated homes in Gosport 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.
- Households ready to give up gas entirely and drop the standing charge
- Combi owners who can find space for a hot water cylinder
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Heat pump cylinder, outdoor unit and weather compensation controls
- 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
- Commissioning, MCS certificate and grant application in England and Wales where eligible
Installers in Gosport take out the old boiler and flue and seal the wall opening as part of the job.
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 Gosport quote.
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.
What to budget for replacing a gas boiler with a heat pump in Gosport
The ranges below are typical installed prices for homes in Hampshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Gosport can need quite different radiators and pipework.
| Home | Typical size | Installed guide price | After £7,500 grant |
|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,800–£12,900 | £2,300–£5,400 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,800–£13,900 | £3,300–£6,400 |
| 3 bedroom semi or small detached | 6–9 kW | £12,350–£15,950 | £4,850–£8,450 |
| 4 bedroom detached | 8–12 kW | £14,400–£18,550 | £6,900–£11,050 |
| 5+ bedroom or larger older house | 11–16 kW | £17,000–£23,200 | £9,500–£15,700 |

Winter daylight and heating in Gosport
On the shortest day Gosport gets about 7 hours 57 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Replacing a gas boiler with a heat pump in Gosport: questions
Can you service a heat pump in Gosport that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Gosport, whoever fitted them. Tell us the make and model when you book.
Do you cover Portsmouth as well as Gosport?
Yes. We arrange surveys and installation in Portsmouth, which is about 2 miles east of Gosport, and across Hampshire.
How long does installation take in Gosport?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Gosport home states the expected time.
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.
Should I have my gas meter removed?
If gas is used for nothing else, removing the meter ends the gas standing charge, which is about £108 a year at the October to December 2026 price cap. If you still cook on gas or have a gas fire, you will need to keep the supply. Meter removal is arranged through your gas supplier, usually once the heat pump is running; the pipe at the boiler position is capped during the installation.
