Ducted air conditioning in Welling
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 an older house in Welling, the loft and any existing bulkheads decide whether a ducted layout will work.
Ducted systems suit Welling loft conversions and new extensions where ceilings are being boarded anyway. We cover Welling as part of London, roughly 10 miles from central London. Homes in DA16 are all within our coverage.

Guide prices show VAT at 20%.

For most houses in Welling, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
