Merton’s licences, ward by ward
Which licence a Merton landlord needs depends on who lives in the home and which ward it is in:
- Selective licence — a home occupied by a single household in Figge’s Marsh, Graveney, Longthornton or Pollards Hill.
- Additional HMO licence — an HMO with three or four people forming more than one household in Colliers Wood, Cricket Green, Figge’s Marsh, Graveney, Lavender Fields, Longthornton or Pollards Hill.
- Mandatory HMO licence — an HMO with five or more people forming more than one household, anywhere in the borough.
In the same seven wards an Article 4 Direction means that converting a home into an HMO for three to six occupants needs planning permission for the change of use. If a property will stop being licensable within three months, a temporary exemption can be applied for instead of a licence. The council’s ward finder confirms an address, and City Hall’s property licence checker shows the schemes on a map.
The EPC is a licence condition
Merton writes the EPC into its selective licence conditions: the licence holder must provide the council with an Energy Performance Certificate for the property within 14 days of demand, alongside copies of the tenancy agreements and tenant references on request. So the certificate has to be valid and to hand, not just lodged once and forgotten — check when yours expires. Most privately rented homes must also be rated E or above unless an exemption has been registered (landlord guide). Checked on Merton Council’s licensing pages on 22 October 2026.
What the assessment looks at in a Merton home
How homes in Merton score today. The ONS’s latest figures use each home’s most recent EPC lodged in the ten years to March 2025. The typical (median) score here is 69, band C, against 70 across London, and 52% of those homes are rated C or above (London 58%). Homes built before 1929 have a median of 65, against 84 for homes built since 2012; flats and maisonettes come out at 72, terraced houses at 66. How every London borough compares.
Merton is a borough of terraces: 35.7% of households live in a terraced house, the second-highest share in London after Barking and Dagenham. 60.4% live in a house of some kind, and 39.6% in a flat.
Wimbledon, Raynes Park and Morden
Wimbledon’s “town” grew up beside the old village after the railway station opened in 1838; Raynes Park was planned in the 1870s as a garden suburb like John Innes’s Merton Park, though only part was built; and in Morden the fields were rapidly divided into building plots until most of the parish was covered in suburban homes. In a terraced house, a neighbour on each side keeps the heat in, so the rating turns on the front and back walls, the roof and loft insulation, the windows and the boiler. Rear extensions and loft conversions are recorded with their own age and construction.
Mitcham and St Helier
Mitcham had social housing schemes in the 1930s, and after the war Eastfields, Phipps Bridge and Pollards Hill were rebuilt with more affordable homes. Part of the St Helier estate, built between 1928 and 1936 by the London County Council, lies in Merton north of Green Lane. For a flat in a block, its position and the heating system matter most; for an inter-war cottage-estate house, the walls and loft insulation.
