Houses in multiple occupation

The definition of a house in multiple occupation (HMO) under the Housing Act 2004 is as follows:

A HMO is a building or part of a building (eg a flat):

  • in which more than one household resides as their only or main residence and shares an amenity e.g. kitchen or bathroom
  • which is a converted building that does not entirely comprise self-contained flats

A household is defined as either a single person or members of the same family who are living together.

HMO landlords must comply with the Management of Houses in Multiple Occupation (England) Regulations 2006, which stipulate the roles and responsibilities of both landlords and tenants.

Changes to Mandatory HMO Licensing

The Government is planning to extend mandatory licensing for Houses in Multiple Occupation. At present mandatory HMO licensing is restricted to properties that are three or more storeys, containing five or more people in two or more households with shared facilities such as a kitchen, bathroom or toilet. Under the new plans the Government intends to make the following changes through secondary legislation:

  • Remove the storey rule so all houses with 5 or more people forming 2 or more households will become mandatory licensable
  • Extend mandatory licensing to flats above and below business premises (regardless of storeys)
  • Set a minimum size of 6.52sq-m for a single room and 10.23 sq-m in line with the existing overcrowding standard (Housing Act 1985) but allowing the local authority to retain the ability to set a higher standard.
  • Tightening up the ‘fit and proper person’ test for landlords and ensuring criminal record checks are carried out

The Government released a consultation paper in November 2016 regarding the decision to extend mandatory licensing. The consultation was to gather views on the proposed changes and to help ensure that once the legislation is implemented it is clear. It is likely the results of the consultation will be released next year along with the secondary legislation.

Where a landlord fails to obtain a licence they could be liable to pay a potentially unlimited fine. It is likely the changes will be implemented in 2018, the website will be updated further as information becomes available. Further information can be found at

Licensing of HMOs

Self-contained flats

Section 257 of the Housing Act 2004 applies to a HMO that is a converted block of flats, where the conversion to flats was completed before 1 June 1992, and where less than two thirds of the flats are owner occupied.

HMOs falling within the definition of section 257 are not subject to mandatory licensing, but may be licensed under section 56 of the Housing Act 2004 - additional licensing.

Landlords of this type of HMO must comply with the Licensing and Management of Houses in Multiple Occupation (Additional Provisions) (England) Regulations 2007 in addition to the regulations linked to above.
