Which rules apply in Lancashire?

Under the Renters’ Rights Act, civil penalties reach £40,000 for offences such as running an unlicensed HMO.
Licensed HMOs must meet national minimum bedroom sizes: 6.51 m² for one person aged 10 or over, 10.22 m² for two, and 4.64 m² for a child under 10.
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.
A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.

Councils in England can add additional licensing and Article 4 directions on top of the national rules. Check the council’s website for the exact address before you buy or start work.
