Before you book: air source heat pump installation in Llantrisant
The question for a Llantrisant 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.
Homeowners across Mid Glamorgan can arrange a survey in Llantrisant for a room-by-room design and a written quote before committing to anything. Many homes in Llantrisant have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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
- Houses with reasonable insulation, or a plan to improve it
- Owners who want one contract covering design, fitting and paperwork
What's included
- Boiler Upgrade Scheme application in England and Wales where eligible
- Commissioning, handover and a walk-through of the controls
- Removal of the old boiler or heaters
- Outdoor unit, hot water cylinder and weather compensation controls
- System design, unit sizing and a written quote
In Llantrisant, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in Wales
Homes in Llantrisant 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.

Winter daylight and heating in Llantrisant
On the shortest day Llantrisant gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Air source heat pump installation in Llantrisant: questions
Do you cover Pontypridd as well as Llantrisant?
Yes. We arrange surveys and installation in Pontypridd, which is about 4 miles north of Llantrisant, and across Mid Glamorgan.
What size heat pump does a Llantrisant 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 Llantrisant home.
How soon can you survey a home in Llantrisant?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
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.
