Ducted air conditioning in Catford
For a renovation in Catford, the best time to plan ducted cooling is before the plasterers arrive. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
Ducted systems suit Catford loft conversions and new extensions where ceilings are being boarded anyway. Catford sits around 6 miles from central London, inside our London area. Coverage includes SE6.
Prices in Catford
In London, our guide range for ducted air conditioning is £7,195–£19,745 per system, including VAT. That is above the UK middle, mainly because labour and access cost more in London. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our London figures, the Zoned option (motorised dampers or two units for separate floors or room groups) is about £9,845–£14,445.

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