Dangerous structures and buildings

A dangerous structure can be anything from a loose slate to a collapsing building.

Report a dangerous structure

What happens next

We have qualified officers on call to investigate reports.

  1. An experienced engineer or surveyor will assess the situation and see if our contractors remove the danger.
  2. We can serve a Dangerous Structure Notice that requires the owner to remove the danger.
  3. If a structure is defective, but not immediately dangerous, we will contact the owner and give them a time limit to fix it.
  4. If the building needs emergency work the owner will, where possible, hire a contractor.


All of our costs are charged to the owner of the building. We will send a demand which will include the total cost of the work carried out. We also include a breakdown showing time spent and materials used. 

We would recommend that owners contact their insurers as soon as possible once they are aware of a problem.
