Which rules apply in Blackwood?
Large HMO conversions (7+ sharers) in Blackwood must satisfy national law for Wales, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Councils such as Cardiff and Swansea run additional licensing for HMOs outside the mandatory scheme.
- England’s national room sizes do not apply in Wales; councils set their own room standards.
- Kitchen and bathroom ratios are set in each council’s HMO standards.
- More than 6 sharers is a sui generis HMO and needs planning permission; councils such as Cardiff apply concentration limits.

Questions about large HMO conversions (7+ sharers) in Blackwood
Do you handle building control?
Yes. The building work in a large HMO conversion (partitions, fire separation, drainage, electrics) needs to meet the building regulations, and the conversion can also count as a material change of use. We confirm the route with building control, coordinate inspections and give you the completion paperwork.
Which postcodes in Blackwood do you work in?
All of them, including CF81, CF82 and NP12, and the surrounding parts of Caerphilly.
Where do I check the HMO rules for an address in Blackwood?
With the local council for the address. 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.
