Astor analyst's read

Lewisham — 58 active Article 4 directions (1 HMO-specific); 2,211 apps in 12 months suggest steady volume but limited HMO regulatory clarity.

Profile

Inner South London mixed residential, moderate density Victorian and inter-war stock with growing intensification; working-class to middle-class character.

Planning

Heavy Article 4 footprint in our records (58 active directions, mostly conservation/demolition-related); HMO-specific controls appear sparse, verify with council for gaps in our coverage.

Deal angle

Bridging potential constrained by conservation-led Article 4 prevalence; HMO read unclear from available data — council verification essential before sizing deals.

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 Lewisham. 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 Lewisham Council before relying on this. gov.uk: HMO licences ↗
