Most UK planning applications involving trees on or near the site require a BS5837 tree survey — if trees could be affected by the development, the local planning authority will usually ask for one before approving.

A BS5837 survey supports planning applications; a tree risk and condition survey addresses ongoing duty of care and public safety, independent of any development.

This depends on the tree's condition, location, and public exposure — high-risk or high-footfall sites are typically re-inspected annually, lower-risk sites every 3-4 years.

Yes — under the Occupiers' Liability Act, anyone responsible for land with public access has a duty of care to manage foreseeable risks, including from trees. A regular tree risk and condition survey provides a clear, defensible record that this duty has been met.

Lenders sometimes request one if a tree is close to the property, particularly on clay soils where subsidence risk is a factor.

Turnaround is usually 5–10 working days from the site visit for most reports. Larger development projects may take longer if we're waiting on plans or information from architects or other consultants.
