Letting in Harrow: selective licensing in six wards
Harrow has designated six wards for selective licensing from 2026, each for five years from its start date: Edgware and Roxeth from 2 May 2026, Greenhill and Marlborough from 6 July 2026, and Wealdstone North and Wealdstone South from 1 September 2026. It applies to any privately rented property in those wards unless an exemption applies, for example a licensable HMO.
The selective licence fee is £786: a £686 administration fee and a £100 management and enforcement fee, the same for a new application and a renewal. The fees page lists no discount linked to the EPC rating.
An HMO with five or more people needs a mandatory licence. Harrow’s HMO page says the previous additional licensing scheme, for three or four people, ended on 5 August 2026, and a new one is scheduled to start on 6 January 2027.

Homes in Harrow
Why homes in Harrow rate as they do
Harrow is outer London, built out along the Metropolitan line. Rayners Lane and Pinner have the 1930s Metroland semis and bungalows, Stanmore and Hatch End have larger detached houses, and Wealdstone and Harrow town centre carry the older terraces and the newer blocks.
For a 1930s semi the useful evidence is any cavity fill, loft top-up, new boiler or extension, because those are the changes that move a rating. A flat in a Harrow town centre block depends on the building, and the flat’s own heating and glazing are what can be recorded.
50.7% of Harrow’s certificates are for homes built between 1930 and 1966, against 32.9% across London, and 26.2% record insulated cavity walls, against 24.4%. 79.5% are heated by a mains gas boiler, and flats and maisonettes are 48.6% of the total.
| Recorded on the certificate | Harrow | London |
|---|---|---|
| Built before 1930 | 16.0% | 31.3% |
| Solid walls, no added insulation | 45.6% | 48.1% |
| Cavity walls, insulated | 26.2% | 24.4% |
| Mains gas boiler | 79.5% | 76.2% |
| Communal heating | 4.7% | 10.8% |
| Electric heating | 15.4% | 12.2% |
On 94.2% of the certificates rated D or lower, the potential rating (every recommendation carried out) is C or better.

Planning permission for HMOs in Harrow
Harrow’s Cabinet approved a new Article 4 Direction on smaller HMOs on 11 June 2026, and it took effect on 12 June. Until then, an HMO with three to six unrelated people did not need planning permission, because the change was automatic under permitted development. The council’s news release says landlords now need planning permission for all HMOs.
Harrow’s licensing page says planning consent status does not affect a licence application, so the two are decided separately. It also says you may need a planning application to change from a dwelling house (Class C3) to a small HMO (Class C4).

Harrow on the Hill, Pinner and Pinnerwood Park
Harrow has 30 conservation areas, grouped as Harrow on-the-Hill, Pinner, Stanmore and Edgware, and Harrow Weald. On the Hill, the council’s table shows Article 4 directions in Harrow Park, Harrow on the Hill Village, South Hill Avenue, Mount Park Estate, and Roxborough Park and The Grove. Roxeth Hill, Harrow School and Sudbury Hill have none.
In Pinner the table shows them in Pinner High Street, East End Farm, West Towers, Pinnerwood Park Estate and Pinner Hill Estate, but not in Waxwell Lane, Moss Lane, Rayners Lane, Eastcote Village or Pinner Road.
Pinnerwood Park was designated in 1989. Since 10 June 1991 an Article 4 Direction has controlled satellite dishes across the area and more in a defined core, and a 1996 direction extended similar controls to the outer streets. In the core, the council’s guidance note says alterations and replacement of windows and doors, except on rear elevations, need planning permission, as do dormers, rooflights and front or side porches. The council says its aim is management rather than restriction.

Edgware and Roxeth from 2 May 2026, Greenhill and Marlborough from 6 July 2026, and Wealdstone North and South from 1 September 2026. Each designation lasts five years. A property that already has an HMO licence does not need a selective one.

The council lists £786: a £686 administration fee and a £100 management and enforcement fee, the same for new applications and renewals. The page lists no EPC-linked discount.
Do I need planning permission for a small HMO in Harrow?
Since 12 June 2026, yes, according to the council’s news release on its new Article 4 Direction. Before that, an HMO with three to six unrelated people did not need it. The licence is decided separately.
Can I replace windows in a Pinnerwood Park house?
The council’s guidance note says that in the core area, alterations or replacement of windows and doors, other than on rear elevations, need planning permission. The outer streets have separate controls, so ask the planning team about your address.
