Dangerous structures

We have powers to deal with dangerous structures under the London Local Authorities Act 2000 and the London Building Acts (Amendment) Act, 1939), so that all structures within the borough that are considered dangerous to the general public are made safe as soon as possible.

Buildings can become dangerous at any time and for many reasons, ranging from old age, ground movement, poor maintenance, vehicle impact, vandalism or design defects, to more dramatic causes such as fire, explosion or storm damage.

Report a dangerous structure

You can report the dangerous structure directly to Building Control, either in person, by telephone or by completing our online form:
