Demolition is dealt with under the Building Act 1984. Generally, it requires six weeks prior notice to be given to the Local Authority Building Control before demolition begins.
The Local Authority Building Control may decide to issue a notice within six weeks on receipt of the notification to specify conditions that need to be met which may include precautions to protect adjoining properties and the public.
Demolition work must also comply with the Construction (Design and Management) Regulations 2015 and a health and safety plan produced by the principal contractor.
Building Regulations relating to site preparation and resistance to contaminants and moisture will need to be met once the preparation work starts on the site.
Please contact local authority Building Control for further advice.
