Air source heat pump installation for Llanelli homes
Most homes can run on a heat pump if the system is designed properly, and Llanelli is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners across Dyfed can arrange a survey in Llanelli for a room-by-room design and a written quote before committing to anything. For older properties in Llanelli, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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.
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Homes replacing a gas, oil, LPG or electric heating system
- Owners who want one contract covering design, fitting and paperwork
What's included
- Commissioning, handover and a walk-through of the controls
- Free home survey and room-by-room heat loss calculation
- Removal of the old boiler or heaters
- Radiator and pipework changes where the design needs them
- Boiler Upgrade Scheme application in England and Wales where eligible
Terraced streets in Llanelli 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
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 Llanelli quote.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

Designing for Llanelli's winters
Llanelli 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.

Air source heat pump installation in Llanelli: questions
Do you cover Gorseinon as well as Llanelli?
Yes. We arrange surveys and installation in Gorseinon, which is about 5 miles east of Llanelli, and across Dyfed.
How soon can you survey a home in Llanelli?
Survey dates depend on how busy installers are in Dyfed. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Llanelli?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Llanelli home states the expected time.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
