Welcome to
West Somerset Council


By law, the Building Control Officer must be told when the work reaches each of the following stages. The officer will then need to inspect your works.

  • Commencement (48 hours before commencing).
  • Excavation for foundations (24 hours before concreting).
  • Foundation concrete (24 hours before covering).
  • Oversite prior to concrete (24 hours before covering).
  • Damp proof courses (24 hours before covering).
  • Drains (24 hours before covering).
  • Drains and soil and vent pipes testing (not more than 5 days after completion).
  • Occupation before completion (not more than 5 days before occupation).
  • Completion (not more than 5 days after completion).

It is normal for other intermediate inspections to be carried out, for example to inspect structural steelwork and floor/roof timbers. The Building Control Officer will be able to advise you if this is necessary. The Building Control Officer may also call at other times to check the work in progress.

The period of time in brackets is the amount of notification that a person undertaking the works is legally obliged to give the council. In practice it is generally possible for an inspection to be carried out on the same day that notification is given, provided that it is received before 10am that day.


We are always looking for ways to improve the Building Control service. Please let us know what you think about our service by completing the Building Control satisfaction survey on our West Somerset Says website.
