Ducted air conditioning in Greenwich
In an older house in Greenwich, the loft and any existing bulkheads decide whether a ducted layout will work. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
For a renovation in Greenwich, the best time to plan ducted cooling is before the plasterers arrive. We cover Greenwich as part of London, roughly 5 miles from central London. That includes the SE10 postcode district.
Prices in Greenwich
Guide prices around Greenwich run from £7,195 to £19,745 per system including VAT. That is above the UK middle, mainly because labour and access cost more in London. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Zoned option in Greenwich (motorised dampers or two units for separate floors or room groups) usually comes to 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
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. On a survey in Greenwich 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.
