Book an inspection

Important update

Once you've made an application for building regulations approval, it's important that you or your builder tell us when the work starts, and when it has reached certain stages. This ensures we can inspect it to check that it meets building regulations.

If we don't get the chance to inspect important work, we have the power to have the works opened up so we can see them. 

You must tell us:

  • When you start the work.
  • When you dig the foundations.
  • When you pour the foundation concrete.
  • When you fit a damp-proof course.
  • When you lay and compress the site hardcore (for example, with a roller).
  • When you lay the concrete subfloor.
  • When you lay the drainage system (both before, and after backfilling)
  • Before covering any sound insulation measures
  • Before covering any above ground structural elements
  • When the work is finished.
  • Any other stages the surveyor on-site asks you to tell us about. 

We may do tests on drains and private sewers or ask you to have the tests carried out. We may also take samples of materials being used to make sure they meet building regulations requirements.
