In particular with the introduction of licencing, the size of bedrooms can matter. Sometimes a local authority can limit the number of occupiers depending on the room sizes or in rare cases can state a room is not suitable for occupation at all.
At the time of updating, minimum room sizes for licensable HMOs are in draft form and assuming passed to take effect from 1 October 2018, will overrule anything in this article from that date for licensable HMOs.
For any rented property not requiring a licence in England or any rented property in Wales, carry on reading.
Housing Act 1985
The legal standards covering overcrowding are contained in the Housing Act 1985 and cover all dwellings.
The occupancy level standards for dwellings are laid down in Part X of the 1985 Housing Act, which specifies maximum permitted occupancy levels in consideration of the total number of habitable rooms available and the number of persons liable to be occupying individual rooms for sleeping purposes.
