Multi-split air conditioning in Dagenham
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. Twin and triple systems suit Dagenham homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit.
In a house in Dagenham with a usable loft, multi-split pipes can often run through it so the front stays clear. Dagenham is about 13 miles from central London and falls within our London coverage. We cover RM10 and the streets around them.

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.

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