Gas boiler to heat pump for Port Talbot homes
Every property in Port Talbot 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.
Rear gardens and side returns in Port Talbot usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Households across West Glamorgan moving off gas can have a survey in Port Talbot 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.

What's included

Grants and rules for heat pumps in Wales
In Wales 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; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Port Talbot quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Replacing a gas boiler with a heat pump in Port Talbot: questions
How long does a heat pump survey take in Port Talbot?
A home survey in Port Talbot usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Do I need new radiators for a heat pump in Port Talbot?
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 Port Talbot home gives a room-by-room list.
How long does installation take in Port Talbot?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Port Talbot home states the expected time.
Will my hot water run out with a heat pump?
Not if the cylinder is sized properly for your household. The survey asks how many people live in the home, how many bathrooms you have and whether you prefer baths or showers, then sizes the cylinder to suit. The heat pump reheats the cylinder on a schedule, often overnight and again during the day, and an immersion heater acts as a backup.
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.
