Client, designer and contractor dutyholder responsibilities

Notable changes

Other notable changes that will affect your projects are: 

Additional information is required to enable your application to be validated, including contact details for dutyholders and information about the project.

For new buildings and extensions this would usually be the date at which the foundations and ground floor structure is complete, or for other works a date and description of a point where 15% of the work is due to be complete.

You must notify building control when you start work on-site so we can carry out the necessary inspections. You must also notify Kingston council when works are ‘deemed commenced’ for buildings and extensions; this is when the foundations are constructed, and the structure of the lowest floor level is complete. For all other works, where 15% of the overall work has been constructed.

A notice of completion must be submitted to us within 5 days of the work being completed.

For projects that do not meet the definition of commencement within 3 years from when the building control approval was granted, 

The Building Safety Act 2022 strengthens enforcement of building regulation breaches and enables local authorities and the Building Safety Regulator to issue compliance and stop notices where building regulations have been breached. Compliance notices will require specified remedial action by a set date. These changes apply to all building projects covered by the Building Regulations 2010, not just higher-risk buildings (HRBs).
