Council full plans
The council examines the submitted design and can approve it, impose requirements or reject it. The published decision period is not a guarantee that an incomplete or non-compliant design will be approved by that date. Missing calculations or unresolved details still need a response from the design team. [1] [3]
Allow a separate period for preparing the submission and answering technical queries. Ask the designer to identify any information that depends on investigation, engineering or a specialist supplier before promising the builder a start date.
A building notice is not rapid plan approval
A building notice does not produce the same formal approval of detailed plans. Although it can allow a different starting procedure for eligible work, it does not remove the need for compliant design or information requested by building control. It should not be described as obtaining full technical approval in a few days. [1]
Check eligibility first. Existing restrictions include relevant Fire Safety Order buildings, work fronting a private street and work engaging the public-sewer requirements. Check whether MHCLG's proposed 2026 changes to plan-approval requirements have taken effect before choosing your route. [4]
Private building control
The initial-notice process includes a five-working-day council consideration period. That concerns the notice, not completion of all design checking by the registered building control approver. Obtain a separate written programme for plan review, responses and the inspections needed before the next construction stage. [5] [6]
A company's estimate should identify the information it needs and the point from which it measures its review period. Compare this with the proposed inspection service rather than interpreting it as a statutory guarantee.
Higher-risk buildings
The BSR guidance gives different determination periods for new higher-risk building applications and work to existing higher-risk buildings: generally 12 weeks and eight weeks respectively, unless a longer period is agreed. Approval is required before the relevant building work starts; a missed target is not permission to proceed. [2]
Completion is a later decision
Approval of plans does not mean the finished work has been signed off. Final inspections, commissioning results, installation certificates and dutyholder declarations may still be required before the completion or final certificate can be issued. [7] [8]
Build the programme around these separate milestones: submission, technical response, readiness to start, inspections and completion evidence. A realistic sequence is more useful than treating the first decision date as the finish of the compliance process.
