Mandatory HMO licensing
The national rule that any HMO occupied by five or more people forming two or more households needs a licence from the council.
In short: Mandatory HMO licensing applies across England to houses in multiple occupation with five or more occupiers from two or more households, whatever the number of storeys, since October 2018. The landlord applies to the council, pays a fee and must meet conditions such as room sizes and safety.

The description is in the Licensing of Houses in Multiple Occupation (Prescribed Description) (England) Order 2018, made under Part 2 of the Housing Act 2004.
A licence:
- is granted to a fit and proper person, usually for up to five years;
- sets the maximum number of occupiers and households;
- comes with conditions: gas and electrical safety, smoke alarms, furniture safety, minimum bedroom sizes and waste storage.
Letting a licensable HMO without a licence is an offence: the council can prosecute or impose a civil penalty of up to £40,000, and tenants can apply for a rent repayment order.
