Report a dangerous structure

Building safety

We operate a 24-hour emergency call-out service to deal with dangerous structures.

How to report

  • During working hours (9am to 5pm), call 020 8921 5413
  • Outside working hours (5pm to 9am), call 020 8854 8888.

What to report

If you know of a building or structure that could pose a threat to people near it, report it. A building can become dangerous or unstable as a result of:

  • vehicle impact
  • serious neglect
  • incorrect building works
  • lightning strike
  • overloading parts of the building.

What happens next

Once you've made the report, a Building Control surveyor visits the site within three hours. The surveyor assesses the danger and decides on the best course of action.

We'll then get the owner's agents to carry out any urgent works. If it isn't possible, we will contact our emergency contractor to work on the problem.
