Ducted air conditioning in Portishead
In the South West, a system that heats well through damp winters is often as valuable as summer cooling. Ducted systems suit Portishead loft conversions and new extensions where ceilings are being boarded anyway.
For a renovation in Portishead, the best time to plan ducted cooling is before the plasterers arrive. Portishead sits around 35 miles from Taunton, inside our Somerset area. We cover BS20 and the streets around them.

In South West England, our guide range for ducted air conditioning is £5,450–£14,950 per system, including VAT. That is close to the UK middle for this kind of work. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Zoned option (motorised dampers or two units for separate floors or room groups) would typically be £7,450–£10,950 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 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
A survey in Portishead 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. On a survey in Portishead 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.
