Wall-mounted air conditioning in Caerphilly
In a semi or terrace in Caerphilly, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.
A single wall-mounted unit is often all a bedroom or sunny living room in Caerphilly needs. Caerphilly is about 16 miles from Bridgend and falls within our Mid Glamorgan coverage. Coverage includes CF83.
Prices in Caerphilly
Wall-mounted air conditioning in Caerphilly typically comes in at £1,045–£2,695 per room including VAT, based on South and Mid Wales rates. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) would typically be £1,445–£1,995 here.

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.
