HMO Conversions Wembley

HMO conversions in Wembley are shaped by Brent rules that go further than the national ones. Outside the areas Brent's HMO SPD exempts, which include the Wembley Growth Area, an article 4 direction in force since 1 November 2022 brings the change from a family house (C3) to a small HMO (C4) under planning control. Since 2 February 2026 Brent has also licensed HMOs of three or four people across the whole borough. We build shared houses, and upgrade existing ones, to the approved layout and the licence standards: room sizes, kitchens and WCs, fire doors, detection and escape routes.

In Wembley, a light HMO conversion for four to six tenants typically costs £40,000 to £75,000 in construction, or £90,000 to £150,000 with an en-suite to every bedroom (indicative London ranges, Mayfair Studio and LetCompliance, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Wembley: we build the fire doors, detection, bathrooms and kitchens to the council's HMO standards, the landlord applies for the licence, and a registered electrician certifies the electrics.

Planning for a Wembley HMO under Brent's article 4 direction

Whether a Wembley house needs planning permission to become a small HMO depends on the address. Brent confirmed an article 4 direction on 3 February 2022, in force from 1 November 2022, that brings the change from a dwelling (C3) to a small HMO (C4) under planning control, where nationally Class L would allow it. Brent's HMO SPD says the direction does not apply in the OPDC area, the Church End Growth Area site allocations or the other seven Growth Areas, and Wembley is one of those Growth Areas. So parts of central Wembley may keep the permitted development right, while streets outside the Growth Area boundary do not. Check the address on Brent's policies map.

Size decides the planning route as well. The London Plan defines an HMO for three to six people as Use Class C4 and one for more than six as sui generis, so a Wembley HMO for seven or more occupants needs planning permission wherever it is. Class L also does not permit a house previously used as a single dwelling to become two or more separate C4 HMOs. The owner or their agent makes any application, and we build to the approved layout and the room schedule that goes with it.

Housing in Wembley

About 17,140 homes are listed for Wembley, and the mix is 29% houses to 71% flats, with 63% built after 1945, 25% in 1919 to 1939 and 12% earlier.

Where Brent accepts a new HMO in Wembley

Brent also tests location before it grants permission for an HMO. Under Policy BH7 an area counts as over-concentrated where three or more of the ten nearest properties are already HMOs, and the HMO SPD requires a location with a PTAL of at least 3. Wembley addresses near the stations may clear the transport test, but the neighbour count is checked address by address, and a street that already has several shared houses can fail it even with good transport.

The London Plan pulls the other way on existing stock. Policy H9 says boroughs should take account of the role of HMOs in meeting housing needs and that HMOs of a reasonable standard should generally be protected. For a Wembley landlord, upgrading an existing, lawful HMO to current standards can therefore be a surer route than creating a new one, because the use is already established and the work is about licence conditions rather than a fresh planning decision.

Room sizes, kitchens and amenity space in a Wembley HMO

Brent's HMO SPD sets the layout of a Wembley HMO room by room. Singles need 7.5m2 of floor and a 2.15m width; rooms for two need 11.5m2 and 2.55m, with any en-suite left out of the sum. Kitchen space must reach 5.5m2 per 3 households or per 5 people, taking the lower, and each group of five occupants needs its own separate WC of 1.3 x 0.9m or more. On a house of up to three storeys the kitchen belongs on the ground floor.

Communal and outdoor space can decide how many rooms a Wembley house will take. The HMO SPD expects a minimum 5m2 of internal communal amenity space per resident, including the kitchen space, and normally seeks at least 20m2 of ground floor outdoor amenity space, with more for over 10 occupants. It also treats the London Plan D6 net internal floorspace standards as the minimum bedroom sizes for planning permission. We check the room schedule against these figures before any partition is built.

Licensing and fire safety for a Wembley shared house

Licensing follows the build. Brent's Additional HMO licensing designation applies to the whole borough and came into force on 2 February 2026, catching privately rented homes let to 3 or 4 occupiers who form two or more households. At five or more people in two or more households sharing a kitchen, bathroom or toilet, a mandatory licence applies instead. Renting out an unlicensed HMO can lead to an unlimited fine. The Wembley landlord applies, and we supply the room measurements and a record of the fire safety works for the application.

Mandatory licensing does not reach a flat in a purpose-built block of three or more self-contained flats; where such a flat is shared, it is the council's additional scheme, if any, that applies.

Fire safety sets the build detail in a Wembley HMO. Bedroom doors onto the escape route become fire doors with self-closers, the stair and landing form a protected route to the exit, and a linked fire detection and alarm system goes in to the standard the licence requires. LACORS housing fire safety guidance is the recognised guide to the level of protection, and Part B applies where the work is building work. Sound insulation between rooms completes the specification. Where the whole house is let on one tenancy, an EPC of E or better applies to existing lets as well as new ones; a room by room let generally needs no EPC, though the licence conditions may ask for one.

• En-suite shower rooms added to bedrooms
• Separate WCs and wash basins to the amenity standard
• Protected escape routes through the hall, stair and landings
