The short answer
Before demolition begins, check whether a Section 80 notice applies to the proposed work. The requirement is set out in the Building Act 1984 and applies to the demolition of a building or part of a building. Exemptions exist — including for some internal demolition and some small structures — but they should be confirmed for the individual project rather than assumed. The relevant local authority must be notified where the requirement applies.
Why it matters
A Section 80 notice triggers a process under which the local authority may attach conditions to the demolition, including requirements for shoring, weatherproofing, disconnection of services and site security. Checking early avoids treating a regulatory step as an afterthought and prevents the programme from being fixed before the authority's requirements are known.
Information that may be needed
A clear description of the proposed demolition, site address, drawings where available and any correspondence with the relevant local authority may be needed. The authority may issue a Section 81 counter-notice setting out conditions.
What can affect the scope
The nature and extent of demolition, the structure involved, any exemptions and the local authority's process can all affect the requirement and the timeline. Some authorities have specific forms or procedures.
When specialist input may be needed
A local authority building control department, planning professional or other adviser may be appropriate where the position is unclear or where the authority issues a counter-notice with conditions.
