In accordance with Regulation 16, anyone required to give a building notice or an application for building control approval with Full Plans to carry out building work, will give the Local Authority notice of their intention to start the work. Two days should have passed after the end of the day on which the notice of starting work was given, before works do begin on site.

Examples of the difference between ‘the start of work’ and ‘work is regarded as commenced’ are given below.

Start of work includes:

For the construction of a new building or an extension, when strip or pad foundations have been excavated or piles have been installed.

Work regarded as commenced includes:

For a large building that shares its foundation with other buildings, when the foundations supporting the building and the structure of the lowest floor level of that building (but not any other buildings or structures to be supported by those foundations) are completed; or

For a small house or an extension to the side(s) of a house when the sub-surface structure of the building or the extension, including all foundations, any basement level (if any) and the structure of ground floor level is completed.
