Which rules apply in Croydon?
The rules below are the England-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Croydon before we price.
- 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.
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
