Building work inspections

Listed below are the various stages (where applicable) when Building Control should be contacted to arrange an inspection of work.

The Building Regulations specify certain statutory notifications where notice must be given. Failure to notify may result in work having to be exposed for inspection.

In calculating the period of days, ‘days’ means any period of 24 hours commencing at midnight and excludes any Saturday, Sunday or Bank Holiday.

If you require a same day visit, please call 01909 533 184 and ask for Building Control before 10:00am.

Notice of commencement should be given two days before any work is undertaken.

Additional inspections may be required depending on the type of project, in order to view items of work that will subsequently be covered up. These may include inspection of roofs, lintels and structural supports, insulation, electrical installations, fire stops and fire protection.

Applicants must advise Building Control at the time of depositing an application whether the electrical installation is being carried out by a person registered under a Competent Person scheme.
