Air conditioning for extensions and kitchen-diners in Becontree
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. In Becontree, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Becontree, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Becontree sits around 11 miles from central London, inside our London area. We cover RM9 and the streets around them.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
On a survey in Becontree 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. Surveys in Becontree cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
