Which rules apply in Aberdare?
The rules below are the Wales-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Aberdare before we price.
- More than 6 sharers is a sui generis HMO and needs planning permission; councils such as Cardiff apply concentration limits.
- 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.
- 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.
- England’s national room sizes do not apply in Wales; councils set their own room standards.
