What is Additional Licensing for HMOs?
Additional licensing is a discretionary power under Part 2 of the Housing Act 2004 that allows local councils to extend HMO licensing requirements beyond the mandatory national standard. While mandatory HMO licensing applies nationally to all properties occupied by five or more persons forming two or more households, additional licensing brings smaller HMOs within the licensing regime in areas where councils have identified problems with HMO management.
As of March 2026, 55 additional licensing schemes are active across England and Wales, concentrated in university cities and areas with high concentrations of shared housing.
What is an HMO?
A house in multiple occupation (HMO) is defined in section 254 of the Housing Act 2004. The standard test is that a property is an HMO if it is occupied by three or more persons who form two or more households, and who share or lack exclusive use of basic amenities such as a bathroom, toilet, or kitchen.
The definition covers bedsits, shared houses, shared flats, hostels, and some purpose-built student accommodation. It does not cover properties where all occupants are members of the same family, or where the landlord lives in the property with two or fewer lodgers.
How Does Additional Licensing Differ from Mandatory HMO Licensing?
Mandatory HMO licensing is the national baseline. It applies to any property occupied by five or more persons forming two or more households. This threshold was set by the Housing Act 2004 and applies uniformly across England and Wales.
Additional licensing is a local extension of this baseline. Under section 56 of the Housing Act 2004, a council may designate an area for additional licensing if a significant proportion of HMOs in the area are being managed ineffectively, causing or likely to cause problems for the occupants or members of the public. Under an additional licensing scheme, smaller HMOs, typically those with three or more occupants forming two or more households, must also be licensed.
The key distinction is scope: mandatory licensing applies everywhere; additional licensing applies only in areas where a council has made a formal designation.
Which Councils Operate Additional Licensing Schemes?
Additional licensing schemes are most common in university cities where large numbers of shared houses exist. As of March 2026, councils operating additional licensing schemes include:
Birmingham: One of the largest additional licensing schemes in England, covering significant parts of the city including Selly Oak, Erdington, and Handsworth.
Leeds: The Leeds additional licensing scheme covers properties in a number of wards with high concentrations of student and shared housing, including Hyde Park and Harehills.
Bristol: Bristol City Council operates an additional licensing scheme covering HMOs with three or more occupants in designated areas.
Nottingham: Nottingham City Council operates an additional licensing scheme covering the majority of the city, including Hyson Green.
Manchester: Several Manchester wards operate additional licensing schemes, including Fallowfield and Rusholme.
London: Several London boroughs, including Hackney and Newham, operate additional licensing schemes alongside their selective licensing schemes.

What Does an Additional Licence Require?
The conditions attached to an additional HMO licence are broadly similar to those for a mandatory HMO licence. They are set out in the licence itself and may include:
- minimum room size standards (sleeping rooms must be at least 6.51 square metres for one adult, 10.22 square metres for two adults);
- fire safety requirements including fire doors, fire alarms, and emergency lighting;
- gas and electrical safety certificates;
- adequate kitchen and bathroom facilities for the number of occupants;
- management obligations including responding to repair requests within specified timeframes.
See our guide to HMO room size requirements for the full standards.
How to Apply for an Additional HMO Licence
Applications are made directly to the local council. The process is broadly similar to applying for a mandatory HMO licence:
- Check whether your property falls within a designated additional licensing area using the Tuxa checker.
- Obtain the required safety certificates (gas, electrical, fire alarm).
- Complete the council's application form, either online or by post.
- Pay the application fee (typically £500 to £1,200 per property).
- Await a property inspection if required by the council.
- Receive the licence, which is typically valid for five years.
See our step-by-step guide to how to apply for a selective licence for more detail on the application process.
What Happens if You Operate an Unlicensed HMO?
Operating an HMO without the required additional licence is a criminal offence under section 72 of the Housing Act 2004. The consequences include:
- an unlimited fine on criminal conviction;
- a civil penalty of up to £30,000 (rising to £40,000 under the Renters' Rights Act 2025);
- a rent repayment order requiring repayment of up to 12 months of rent;
- a banning order under the Housing and Planning Act 2016.
