Gas boiler to heat pump in Bognor Regis: what to expect
The question for a Bognor Regis home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Many gas-heated homes in Bognor Regis have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Installers in Bognor Regis 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.
- Combi owners who can find space for a hot water cylinder
- System or regular boiler homes with an existing airing cupboard
- Boilers that are old, unreliable or due for replacement
What's included
- Capping of the gas pipe at the boiler position where you are giving up gas
- Free survey with heat loss calculation and cylinder siting
- System flush and radiator upgrades where the design calls for them
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Heat pump cylinder, outdoor unit and weather compensation controls
Households across West Sussex moving off gas can have a survey in Bognor Regis that compares running costs on realistic assumptions.
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 Bognor Regis quote.
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.

How long is the heating season in Bognor Regis?

Replacing a gas boiler with a heat pump in Bognor Regis: questions
Can you service a heat pump in Bognor Regis that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Bognor Regis, whoever fitted them. Tell us the make and model when you book.
Do you cover Chichester as well as Bognor Regis?
Yes. We arrange surveys and installation in Chichester, which is about 6 miles north-west of Bognor Regis, and across West Sussex.
Do I need new radiators for a heat pump in Bognor Regis?
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 Bognor Regis home gives a room-by-room list.
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.
