Report a dangerous structure
Buildings and structures can show signs of collapsing, while materials like timber, masonry or tiles may fall from them. This is dangerous and should be reported.
What to do it it's causing immediate danger
If you think a structure is dangerous, phone us on 020 8496 3000 and:
- tell us where the building or structure is
- describe the danger
- give your name, phone number or email address
If it's not causing immediate danger
If you think the building or structure is defective, but not dangerous, you can tell us by completing our online form.
The owner must pay for any work we do to remove the risk.
What happens next?
After we get your report, a surveyor will visit the site to assess the danger and any risks.
If the structure is not dangerous, we'll ask the owner to remove the risk in 14 to 28 days.
If the owner doesn’t remove the risk, we can get a court order requiring them to do so.
If they don't comply with the order, we’ll carry out the work ourselves.
