Site Safety
What should I do if building work affects a neighbour's property?
If there is an immediate danger, arrange emergency assistance and stop unsafe activity through the person controlling it. Otherwise record the concern, notify your builder and relevant insurer, and obtain technical advice to prevent further damage. Check approval conditions and any boundary, access or protection-work requirements. A dilapidation report can assist with evidence but does not decide liability. Seek legal advice about disputed rights, damage or compensation.
