Which rules apply in Llantrisant?
Large HMO conversions (7+ sharers) in Llantrisant 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:
- 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.
- 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 Llantrisant
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.
Do you cover all of Llantrisant?
Yes. We work across Llantrisant and the CF38 and CF72 postcode areas, plus the rest of Rhondda Cynon Taf. Nearby places we also cover include Pontypridd, Tonypandy, Whitchurch.
