Garden room and home office air conditioning in Dorset

Garden room and home office air conditioning across Dorset

For a garden room in Bournemouth, the outdoor unit usually sits on a small stand behind the building. We check the armoured supply cable on every Bournemouth garden room before quoting. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.

Prices in Dorset

Our South West England guide price for garden room and home office air conditioning is £1,450–£3,150 per system, VAT included. That is broadly in line with national guide prices. What moves a quote in Dorset up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our South West England figures, the Popular option (3.5 kW unit with Wi-Fi to warm up before you walk down the garden) is about £1,795–£2,450.

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

For most houses in Dorset, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.

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. 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.
