Building rules in Caerphilly
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Caerphilly County Borough Council handles building control for Caerphilly. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.
