- 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.
