HMO Conversions Cockfosters

HMO conversion in Cockfosters needs planning permission before the house is let as a shared house. Enfield adopted a borough-wide Article 4 direction in October 2013 that takes away the permitted development right to turn a family house into a small shared house. The direction was made to safeguard family housing, and in Cockfosters the house in question is often a semi. We build to the approved scheme and the licence standards, and the landlord applies for the permission and the licence.

In Cockfosters, 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 Cockfosters: 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 a Cockfosters shared house under Enfield's Article 4

Turning a Cockfosters family house into a shared house needs a planning application. Class L of the General Permitted Development Order would normally allow a change from a Class C3 dwellinghouse to a Class C4 HMO. Planning Data, however, records a borough-wide Enfield Article 4 direction on houses in multiple occupation, with permitted development rights removed. An appeal decision records that it was implemented in 2013 to safeguard existing family housing, and the application is judged against that aim.

The size of the house in multiple occupation matters too. The London Plan glossary defines HMOs for three to six people as Class C4 and larger ones as sui generis, which needs planning permission anywhere. Class L also does not permit one former house to become two or more separate C4 HMOs. Enfield's Policy DMD5 also sets criteria for converting existing homes into HMOs, including the limit of 20% of properties along any road, so a Cockfosters landlord checks the street before buying.

What London policy says about HMOs, and what it means in Cockfosters

London policy does not treat HMOs as a problem to be removed. London Plan 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. It also says that when boroughs consider Article 4 Directions on changes between C3 and C4, they should weigh the strategic as well as local importance of HMOs. For a Cockfosters landlord, that supports keeping an existing, well-run shared house.

A new HMO in Cockfosters is a harder case, because Enfield's evidence points the other way. The borough's 2010 Strategic Housing Market Assessment identifies a need for larger family sized dwellings and an oversupply of smaller single person accommodation. So an application to convert a family semi needs a clear case from your agent. Upgrading an HMO that already has its use established is often the simpler project, and the building work is much the same.

Mandatory and selective licensing for a Cockfosters HMO

Licensing for a Cockfosters HMO starts with the national definition. GOV.UK defines an HMO as a property rented out by at least 3 people who are not from 1 household but share facilities like the bathroom and kitchen. It defines a large HMO as one rented to 5 or more people who form more than 1 household. A large HMO needs a mandatory licence, and GOV.UK says even a smaller HMO may still need one depending on the council area.

One exception matters here: a flat in a purpose-built block of three or more self-contained flats falls outside mandatory licensing, although a council's additional scheme can still cover it.

Enfield also designated a selective licensing area on 1 September 2021, which was due to end on 31 August 2026, according to a tribunal decision. Whether a scheme now covers your Cockfosters street is for Enfield Council to confirm. GOV.UK says renting out an unlicensed HMO can lead to an unlimited fine. The landlord applies for the licence, and we build to the conditions it sets, so the works schedule is written with the licence standards in hand.

Room sizes, kitchens and fire safety in a Cockfosters HMO

The layout of a Cockfosters HMO is drawn around room sizes and shared space. Every licensed HMO in England carries the national room size conditions, so each bedroom in a Cockfosters semi is measured against them. One sleeper over 10 needs 6.51 square metres, two need 10.22, and a room under 4.64 square metres cannot be slept in at all. Enfield's HMO Standards for Bedsit/Letting rooms and Shared House Accommodation (2021) seek a minimum kitchen/diner of 12.5 square metres for 6 to 10 occupants, so the kitchen is often the room that decides how many people the house takes.

Fire safety is the other half of the build. An Enfield tribunal case lists a penalty where doors were not 30-minute fire resistant and a ceiling had flammable polystyrene tiles, and Enfield has also penalised disrepair under Regulation 7(1) of the HMO management regulations. In a Cockfosters house we fit fire doors with closers and seals, remove combustible ceiling finishes, protect the escape stair and install interlinked detection, following Part B and the LACORS housing fire safety guide.

• Shared kitchens enlarged or added for the number of occupants
• Existing HMOs upgraded to meet their licence conditions
• Protected escape routes through the hall, stair and landings
