If your property is in Coulsdon or the CR5 district or nearby Purley, Wallington and Sutton, it is within our Greater London coverage. It is around 13 miles south of London.

For commercial buildings in Coulsdon, the survey also considers building use and fire requirements before a material is specified. Per-address photo records for Coulsdon properties make compliance files and EPC updates straightforward.

Wind-driven rain is the first thing the surveyor weighs up. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

What is different on commercial jobs

Work is usually standard-rated for VAT unless the building qualifies for a relief, which we confirm on the quote.
