Air conditioning for period and listed homes in Caernarfon
Exposed coastal sites in North Wales call for outdoor units placed out of the wind and salt spray where possible. If your home in Caernarfon is Victorian, Edwardian or older, a console or concealed system often works better than a high wall unit.
For period homes in Caernarfon, we look at consoles in place of radiators and ducted units from the loft before anything else. Our Gwynedd coverage takes in Caernarfon, about 8 miles from Bangor, Gwynedd. We cover LL55 and the streets around them.
Prices in Caernarfon
In North Wales, our guide range for air conditioning for period and listed homes is £1,545–£7,445 per home, one room upwards, including VAT. Labour rates in North Wales keep this slightly under the national middle. What moves a quote in Caernarfon up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our North Wales figures, the Concealed option (ducted unit from a loft or void serving one or two rooms) is about £3,245–£5,095.

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 Caernarfon 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
On a survey in Caernarfon 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. A survey in Caernarfon 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.
