Which rules apply in Surrey?

Licences last up to 5 years and carry conditions on gas and electrical safety, alarms, room sizes and waste.
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.
7 or more sharers is a sui generis large HMO and normally needs planning permission.
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.
