- 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.
- Council HMO standards and the fire risk assessment set detection, fire doors and escape routes.
- Kitchen and bathroom ratios are set in each council’s HMO standards.
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.
