Ducted air conditioning in Llanelli
Ducted systems suit Llanelli loft conversions and new extensions where ceilings are being boarded anyway. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.
In an older house in Llanelli, the loft and any existing bulkheads decide whether a ducted layout will work. Llanelli sits around 13 miles from Carmarthen, inside our Dyfed area. Homes in SA15 are all within our coverage.

That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. On a survey in Llanelli the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
