The legal mechanism

Under Section 36 of the Building Act, a local authority can serve notice requiring non-compliant work to be altered or removed. Notices are subject to time limits but they are real.

What usually happens instead

Most disputes settle short of formal notice. Building Control issues a written list of non-conformities, work is opened up and corrected, and a Completion Certificate eventually follows.

Why early oversight matters

Removal-and-replace becomes more likely the longer non-compliant work stays hidden. Independent stage-by-stage oversight prevents that situation from arising.
