Which rules apply in Caerphilly?

England’s national room sizes do not apply in Wales; councils set their own room standards.
Fitness for human habitation rules require mains-powered, interlinked smoke alarms on every storey and CO alarms where there is a gas, oil or solid-fuel appliance.
Building regulations cover structural work, partitions, drainage, fire-resisting construction and electrics; confirm with building control whether the conversion is a material change of use.
Kitchen and bathroom ratios are set in each council’s HMO standards.
Council HMO standards and the fire risk assessment set detection, fire doors and escape routes.

Welsh councils set their own HMO standards and may run additional licensing. In Wales, changing a house to a C4 HMO always needs planning permission, so check planning first.
