Additional HMO Licence: Which London Boroughs Require One?

The question of which London boroughs require an additional HMO licence is one we are asked almost daily. The answer changes regularly as councils introduce, extend, and sometimes discontinue their schemes. Here is an updated overview.

What is an additional HMO licence?

Under Part 2 of the Housing Act 2004, local authorities can introduce additional licensing schemes for HMOs that fall below the mandatory threshold. These cover smaller properties — typically those with three or more tenants — in designated areas.

Which London boroughs require additional licences?

As of 2025, a significant number of London boroughs operate additional HMO licensing schemes. These include: Barking and Dagenham, Barnet, Brent, Camden, Croydon, Ealing, Enfield, Hackney, Hammersmith and Fulham, Haringey, Harrow, Havering, Hounslow, Islington, Kensington and Chelsea, Lambeth, Lewisham, Merton, Newham, Redbridge, Southwark, Tower Hamlets, Waltham Forest, Wandsworth, and Westminster.

Important caveats

Even within boroughs that operate additional licensing schemes, the scheme boundaries are not always borough-wide. Many boroughs designate specific postcode areas. Your property's address determines whether it falls within a scheme boundary.

Additionally, schemes are time-limited and must be renewed. A borough that had an additional licensing scheme last year may have let it expire, while another may have introduced a new scheme. Always verify current status for your specific address.
