Air conditioning for period and listed homes in Carmarthen
In South and Mid Wales, efficient heating is often as important as cooling. If your home in Carmarthen is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit.
For period homes in Carmarthen, we look at consoles in place of radiators and ducted units from the loft before anything else. We cover Carmarthen and the rest of Dyfed, including Llanelli and Ammanford. We cover SA31 and the streets around them.
Prices in Carmarthen
Our South and Mid Wales guide price for air conditioning for period and listed homes is £1,495–£7,295 per home, one room upwards, VAT included. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Concealed option (ducted unit from a loft or void serving one or two rooms) would typically be £3,145–£4,995 here.
Console
Low-level console in place of a radiator, rear outdoor unit.
Concealed
Ducted unit from a loft or void serving one or two rooms.
Mixed
Consoles downstairs and ducted upstairs on one system.
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%.
Listed building consent
Listed homes in Carmarthen need listed building consent from the council before any work, and permitted development does not apply to them. We plan low-impact routes, keep outdoor units out of sight and provide the details a consent application needs. 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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. A survey in Carmarthen usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
