Which rules apply in Denbighshire?
- Mandatory licence for HMOs with 3 or more storeys and 5 or more people in 2 or more households; Wales did not adopt England’s 2018 change.
- 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.
- 3–6 sharers is use class C4, and in Wales changing a house to C4 always needs planning permission; only C4 back to C3 is permitted development.
- 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.
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.
