Gas boiler to heat pump in Bishopston: what to expect

Homes around Bishopston range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.

Many gas-heated homes in Bishopston have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Installers in Bishopston 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.

  • Boilers that are old, unreliable or due for replacement
  • Households ready to give up gas entirely and drop the standing charge
  • Homes in England and Wales eligible for the Boiler Upgrade Scheme

What's included

  • 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
  • Commissioning, MCS certificate and grant application in England and Wales where eligible
  • Heat pump cylinder, outdoor unit and weather compensation controls
  • Removal of the gas boiler, flue and any loft tanks

If your Bishopston home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.

Grants and rules for heat pumps in England

England

Homes in Bishopston 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.

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.

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

Do you cover Westbury-on-Trym as well as Bishopston?

Yes. We arrange surveys and installation in Westbury-on-Trym, which is about a mile north-west of Bishopston, and across Bristol.

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

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 Bishopston home gives a room-by-room list.

What size heat pump does a Bishopston 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 Bishopston 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.

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.
