Bromley HMO & Article 4 planning

0 applications in the last 12 months

Astor analyst's read

Bromley — 108 active Article 4 directions on record; HMO status unclear, verify with council.

Profile

Outer London suburban borough, predominantly lower-density residential and family stock with growing town centres.

Planning

108 Article 4 directions in our records, though none flagged HMO-specific in our metadata — confirm HMO restrictions directly with Bromley planning.

Deal angle

Heavy Article 4 footprint suggests regulatory friction; absence of HMO sub-flagging requires council verification before sizing bridging or HMO plays.

01 · Planning permission
No HMO Article 4 in our records

No HMO Article 4 direction in our records for this borough. Where no direction applies, converting a home to a small HMO (C4, up to six occupants) is usually permitted development — but coverage can be incomplete, so verify with the council before relying on this.

02 · Licence to operate
Mandatory HMO licence National
5 or more occupants forming 2 or more separate households

Any HMO occupied by five or more people making up two or more separate households (sharing a kitchen, bathroom or toilet) must hold a mandatory HMO licence. This applies in every council in England, regardless of the number of storeys.

No Additional or Selective licensing scheme in our records for Bromley. Many boroughs operate schemes that extend licensing to smaller HMOs or all rented homes, and these change on five-year cycles — check the council's current designation via the gov.uk licence finder ↗.
03 · Minimum room sizes
One person aged over 10 6.51 m²
Two people aged over 10 10.22 m²
One person aged under 10 4.64 m²
Any sleeping room ≥ 4.64 m²
Kitchen, bathroom & WC standards

Licensed HMOs must provide adequate, well-located cooking, washing and toilet facilities for the number of occupants, plus safe gas/electrics, working fire detection and proper waste storage. The exact ratios (occupants per bathroom, per WC, kitchen size) are set by each council in its own HMO amenity standards — confirm the figures with the borough before committing to a scheme.

Minimum room sizes and the mandatory-licensing threshold are national law (Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018), sourced under the Open Government Licence v3 — they apply in every council. Licensing designations shown are those in our records; verify the current position and exact amenity standards with Bromley Council before relying on this. gov.uk: HMO licences ↗
