Dangerous structures

Our Building Control Service is responsible for investigating reported dangerous structures.

Experienced building control surveyors and structural engineers are available 24 hours a day, 365 days a year and provide an out of hours service to investigate situations where there is an imminent danger of collapse of a building or a serious hazard to the public.

Building and structures may become dangerous as a result of old age, deterioration or settlement or by more dramatic causes such as an explosion, fire, vehicle impact or storm damage.

We have powers under section 61 of the London Building Act 1939 to deal with any building or structure that is in a dangerous condition or overloaded.

In the case of imminent danger or collapse of a building or structure, the local authority will use its powers, as necessary, where the owner is not is the position to undertake necessary remedial works (or the contractor is not competent / able) to make safe within an agreed time-frame.

This may include (but is not restricted to) the provision of fencing / hoarding, support scaffolding, demolition or any other means to ensure public safety.  

All costs incurred will be recoverable from the responsible person (usually the owner of the building / structure) including costs related to surveying, emergency contractors, administration / management of the works and  service of notice.

It is usually cheaper for the owner to arrange their own contractors to undertake the work where possible.

In cases where a less imminent danger exists we will make a report to the owner of the building or structure to make it safe or to demolish it.
