HMO Conversions Wood Green

A shared house in Wood Green starts with two Haringey hurdles. Where Haringey's C3 to C4 Article 4 Direction applies, in force since 30 November 2013, even a small C4 HMO needs planning permission. Policy DM17 then asks whether the house as first built had more than 120m2 of gross internal floor space. Every rented HMO in the borough also needs a licence under the additional scheme. So the work here is either a new HMO that has cleared planning, or an existing HMO brought up to licence standards.

In Wood Green, 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 Wood Green: 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 new HMO in a Wood Green house

A new HMO in Wood Green is likely to need planning permission before the work is priced. Nationally, Class L lets a C3 house become a C4 HMO for three to six people without planning permission. Haringey's Article 4 Direction, in force since 30 November 2013, takes that right away wherever it applies, so check the direction map for your address. Above six residents an HMO is sui generis, so permission is always required. Class L never allows one former house to become two or more separate C4 HMOs.

If the building is listed, the works themselves are a separate question: anything that affects its character, inside or out, needs listed building consent from Haringey Council, and carrying it out without consent is a criminal offence.

Policy DM17 then sets the size test: the house as originally built must have more than 120m2 of gross internal floor space before it can become an HMO. With 34% of homes here terraced houses, a smaller Edwardian terrace may fall short, so the measured survey comes first. The London Plan asks boroughs to weigh the strategic as well as local importance of HMOs, but the decision on your house turns on Haringey's own tests.

Housing in Wood Green

Wood Green's housing, as the Council Tax list records it, is about 9,700 homes: 38% houses, 62% flats, with 67% pre-1919, 4% interwar and 29% built since 1945.

Haringey's additional licensing and what it means for the build

Every rented HMO in Wood Green needs a licence. Haringey's additional licensing designation (No 4, 2024) applies across the whole borough from 17 June 2024 until 16 June 2029. It catches every rented HMO, and Section 257 HMOs too, meaning converted blocks of flats that count as HMOs. Separately, national rules make a licence mandatory for a large HMO, one let to five or more people in two or more households.

The landlord applies for the licence, and we build to the conditions it sets. If the HMO lacks a planning permission it should have, Haringey issues a shorter licence, normally for 1 year. The planning position therefore has to be settled before the licence and the build. Letting an HMO that should be licensed but is not can bring an unlimited fine, according to GOV.UK, so the works and the licence timetable are planned together.

Room sizes, kitchens and bathrooms to Haringey HMO standards

The licence conditions set the layout. Under Haringey's HMO licence conditions for 2024 to 2029, a bedroom for one occupant over 10 years old needs a floor area of 6.51 square metres or more. That matches the national minimum, alongside 10.22 for two and no sleeping room under 4.64. Partitions are set out to those figures before the stud walls go up. Where bathrooms are shared, each five occupiers need a bath or shower and a WC of their own. Once a Wood Green house holds six or more sharers, that means a second bathroom or en-suites.

Kitchens follow the same arithmetic. One shared kitchen can serve no more than three lettings under Haringey's standards, so an HMO with four or more lettings needs a second kitchen or kitchenettes in the rooms. Haringey also bars cooking facilities from the staircase enclosure, which rules out a kitchenette on the landing of a narrow terrace. We plan the drainage and extract for every kitchen and bathroom at the start, since they set the plumbing runs.

Fire safety, sound and energy in a Wood Green HMO

Fire safety is the heart of an HMO build. The staircase becomes a protected escape route, bedroom doors become self-closing fire doors, and an interlinked fire detection and alarm system covers the rooms, the stair and the kitchen. The level of protection follows Part B, the licence conditions and the LACORS housing fire safety guidance, which councils treat as the recognised guide. Old openings and service holes in an Edwardian Wood Green house are fire-stopped before the ceilings close.

Sound matters too, since each letting is a separate household. Insulating the floors and partitions between bedrooms reduces complaints and helps the house let. The energy rating also needs attention. Where the MEES Regulations cover the house, a rating below E has barred letting without a valid exemption since 1 April 2020, for existing tenancies as well as new ones. Insulation and heating controls therefore go in while the house is opened up.

• Small HMO conversions for three to six sharers
• Interlinked smoke and heat alarms, mains-wired and graded to the council's HMO fire guidance

Trusted HMO Conversions in Wood Green

An HMO build is judged against a licence schedule, not just a drawing. We set out rooms to the licence sizes, build the fire protection and detection first, size the kitchens and bathrooms to the occupancy, and leave a clear record of fire doors, alarms and certificates for the licence inspection. The landlord applies for the planning permission and licence; we build to both and give one written programme from strip-out to handover.

• Free follow-up visit after completion if anything needs attention
• Sound lining between bedrooms so one sharer does not keep another awake
• EPC upgrades done while the walls and floors are still open
