Air source heat pump installation in Swansea: what to expect
Homes around Swansea range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Many homes in Swansea have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. Installers working in Swansea plan the order of work so heating and hot water are off for as short a time as practical.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Homes replacing a gas, oil, LPG or electric heating system
- Houses with reasonable insulation, or a plan to improve it
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- System design, unit sizing and a written quote
- Outdoor unit, hot water cylinder and weather compensation controls
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
- Free home survey and room-by-room heat loss calculation
Terraced streets in Swansea often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
Grants and rules for heat pumps in Wales
Homes in Swansea can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
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.
What to budget for air source heat pump installation in Swansea
These are guide prices for West Glamorgan, 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.

|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,500–£12,500 | £2,000–£5,000 |

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning.
Designing for Swansea's winters
Swansea has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 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.
From survey to switch-on in Swansea
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Swansea home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Swansea: questions
How long does installation take in Swansea?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Swansea home states the expected time.
How long does a heat pump survey take in Swansea?
A home survey in Swansea 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 Swansea?
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 Swansea home gives a room-by-room list.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
