Before you book: replacing a gas boiler with a heat pump in Haverhill

Most homes can run on a heat pump if the system is designed properly, and Haverhill is no different. The key is matching the heat pump and radiators to the home's heat loss.

Installers in Haverhill take out the old boiler and flue and seal the wall opening as part of the job. Semi-detached and terraced houses in Haverhill often have an airing cupboard that can be reused for a heat pump 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
  • System or regular boiler homes with an existing airing cupboard
  • Homes in England and Wales eligible for the Boiler Upgrade Scheme

What's included

  • Free survey with heat loss calculation and cylinder siting
  • Removal of the gas boiler, flue and any loft tanks
  • Commissioning, MCS certificate and grant application in England and Wales where eligible
  • Capping of the gas pipe at the boiler position where you are giving up gas
  • Heat pump cylinder, outdoor unit and weather compensation controls

Households across Suffolk moving off gas can have a survey in Haverhill that compares running costs on realistic assumptions.

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 Haverhill 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.

Haverhill has about 7 hours 44 minutes of daylight at midwinter and 16 hours 45 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

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

Can you service a heat pump in Haverhill that someone else installed?

Yes. We arrange servicing and repairs for most air source heat pumps in Haverhill, whoever fitted them. Tell us the make and model when you book.

Do I need new radiators for a heat pump in Haverhill?

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 Haverhill home gives a room-by-room list.

How long does installation take in Haverhill?

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

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.

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.
