Gas boiler to heat pump in Fareham: what to expect

A heat pump suits most Fareham homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.

If your Fareham home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Households across Hampshire moving off gas can have a survey in Fareham that compares running costs on realistic assumptions.

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.

  • Homes in England and Wales eligible for the Boiler Upgrade Scheme
  • Combi owners who can find space for a hot water cylinder
  • 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
  • System flush and radiator upgrades where the design calls for them
  • Capping of the gas pipe at the boiler position where you are giving up gas
  • Free survey with heat loss calculation and cylinder siting
  • Heat pump cylinder, outdoor unit and weather compensation controls

Semi-detached and terraced houses in Fareham often have an airing cupboard that can be reused for a heat pump cylinder.

Grants and rules for heat pumps in England

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 Fareham 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.

Fareham sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 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.

How installation works in Fareham

  3. The design and quote arrive in writing, including radiator changes and the outdoor unit position.
  4. On installation days the old system is removed and the new one fitted and filled.
  5. We commission the heat pump, show you the controls and register the installation.

Replacing a gas boiler with a heat pump in Fareham: questions

How soon can you survey a home in Fareham?

Survey dates depend on how busy installers are in Hampshire. We offer the next available dates when you enquire and confirm them in writing.

What size heat pump does a Fareham home need?

It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Fareham home.

How long does installation take in Fareham?

Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Fareham home states the expected time.

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.

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.
