Which rules apply in Southall?
Here is what usually applies to a Southall job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- Under the Renters’ Rights Act, civil penalties reach £40,000 for offences such as running an unlicensed HMO.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
