Conservatory air conditioning in Feltham
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. Conservatories and orangeries in Feltham can swing from too hot in July to too cold in January.
In Feltham, the indoor unit usually goes on the original house wall inside the conservatory. Feltham is about 13 miles from central London and falls within our London coverage. We cover TW13 and the streets around them.
Prices in Feltham
Our London guide price for conservatory air conditioning is £1,895–£4,545 per system, VAT included. That is above the UK middle, mainly because labour and access cost more in London. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. On our London figures, the Popular option (5 kW unit with Wi-Fi for a medium conservatory or orangery) is about £2,445–£3,445.

3.5 kW unit for a small lean-to or Edwardian conservatory.

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.
