Gas boiler to heat pump in Dursley: what to expect

Every property in Dursley is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.

If your Dursley home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Rear gardens and side returns in Dursley usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.

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
  • Homes in England and Wales eligible for the Boiler Upgrade Scheme
  • System or regular boiler homes with an existing airing cupboard

What's included

  • 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
  • System flush and radiator upgrades where the design calls for them
  • Removal of the gas boiler, flue and any loft tanks
  • Free survey with heat loss calculation and cylinder siting

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

Grants and rules for heat pumps in England

England

Homes in Dursley 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.

Guide prices for replacing a gas boiler with a heat pump in Dursley

These are guide prices for Gloucestershire, 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.

What happens after you enquire in Dursley?

  1. Tell us about your home: postcode, property type and current heating.
  2. We book a survey in Dursley; the surveyor measures rooms, windows and radiators and looks at cylinder space.
  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 Dursley: questions

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

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

What size heat pump does a Dursley 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 Dursley home.

How long does installation take in Dursley?

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

Can a heat pump replace a combi boiler?

Yes, but you need room for a hot water cylinder, because heat pumps store hot water rather than heating it on demand. Most homes find a space in a cupboard, utility room, garage or under the stairs, and compact or combined indoor units help where space is tight. The survey measures the options first, so you know where everything will go before you accept the quote.

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.
