Garden room and home office air conditioning in Blackwood
Garden offices used every day in Blackwood need cooling in summer and efficient heat in winter. In South and Mid Wales, efficient heating is often as important as cooling.
For a garden room in Blackwood, the outdoor unit usually sits on a small stand behind the building. Blackwood sits around 19 miles from Bridgend, inside our Mid Glamorgan area. Homes in NP12 are all within our coverage.

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.

We book surveys in Blackwood at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
