Information about changes to council services as a result of coronavirus

Building Control surveyors carry out site inspections during the construction phase of building projects that have been submitted for building regulation approval.

The number and nature of the inspections vary according to the type and complexity of the work being undertaken.

  • At least 48 hours notice is required before a project can be started - by email, phone or using the commencement card sent with the approval notice
  • If work commences prior to approval, all work is undertaken at the owners' risk

Normally, inspection requests received before 10am will be carried out the same day. Please try to plan ahead so that the work to be inspected is actually ready when the surveyor calls.

A completion certificate will then be issued and should be kept in a safe place as it will be required to be produced during any future sale.

For commercial projects and new housing, the above inspections (where appropriate) will be carried out. Additional inspections such as fire stopping checks and general construction inspections, will also be undertaken depending on the size and scale of the project.
