HMO Conversions Crouch End

HMO conversion in Crouch End is tightly controlled. Haringey has had an Article 4 Direction since 2013 removing the permitted development right to turn a family house into a small HMO where it applies, and it licenses every rented HMO in the borough. The VOA's count for Crouch End West, Crouch End East and Hornsey Vale has only 24% of homes as houses, so the pool of candidates is small. The work that does arise is a planned HMO in a large house with consent, or an existing shared house brought up to Haringey's licence conditions. We build to those standards for the landlord.

In Crouch End, 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 Crouch End: 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 an HMO in Crouch End after the 2013 Article 4

Class L of the General Permitted Development Order 2015 normally lets a house change from C3 to a small HMO in Class C4 without an application. Haringey has an Article 4 Direction removing that right, in force since 30 November 2013. Your agent confirms it covers the Crouch End address, and where it does, even a small shared house needs planning permission. The London Plan glossary defines HMOs for three to six people as C4 and larger ones as Sui Generis, which need permission anywhere.

Haringey Policy DM17 permits converting a larger home to an HMO only where the gross original internal floor space is greater than 120m2. In Crouch End that can rule out a smaller two-storey terrace and leave the taller houses. The landlord or their planning agent makes the application, and the approved layout fixes the number of rooms, the shared kitchens and the bathrooms. We price and build that layout, not an earlier sketch, because any extra room means a new application.

Housing in Crouch End

Crouch End has around 10,270 homes on the Council Tax list: 30% post-war, 4% interwar and 66% predate 1919, with 76% flats and 24% houses.

Haringey's additional HMO licensing and what it asks of a Crouch End house

Haringey's borough-wide additional HMO licensing designation (No 4, 2024) came into force on 17 June 2024 and ends on 16 June 2029. Under it every rented HMO in the borough needs a licence, including Section 257 HMOs, which are converted blocks of flats. That sits on top of the national rule. GOV.UK defines a large HMO as one rented to 5 or more people who form more than 1 household, and a mandatory licence applies to those in any area, except a flat in a purpose-built block of three or more flats.

The landlord applies for the licence; we build to its conditions. Where an HMO is being used without the planning permission it needs, Haringey will grant a shorter licence, usually 1 year, so a Crouch End landlord gains nothing by building ahead of consent. GOV.UK also says renting out an unlicensed HMO can lead to an unlimited fine. For the build, that means the planning decision, the licence conditions and the approved drawings agree before the first wall goes up.

Room sizes, bathrooms and kitchens in a Crouch End HMO

Haringey's 2024-2029 HMO licence conditions require any room used for sleeping by one person aged over 10 to be at least 6.51 square metres. That matches the national conditions, which also set 10.22 square metres for two adults and bar any room under 4.64 from use for sleeping. That is measured on the finished floor, so in a Crouch End house the partition positions, the chimney breasts and any boxing for pipes all count against it. We set out each room to the licensed size before first fix, and where a room falls just short we move the partition while it is still studwork.

Haringey's HMO standards require at least one bath or shower and one WC for every five occupiers where these are shared, and one set of kitchen facilities to a maximum of three lettings. Those ratios drive the drainage: a five-letting Crouch End house needs a second kitchen, and a sixth occupier brings a second shower room and WC, each with its own waste run. Kitchen facilities must never be installed within a staircase enclosure, so the shared kitchen goes in its own room off the escape route.

Fire doors, alarms and escape in a Crouch End shared house

Fire safety is the core of an HMO build, because several unrelated people sleep behind separate locked doors. In a Crouch End terrace the stair is the only way out, so it becomes a protected route. That means fire doors with self-closers to every letting room and the kitchen, fire-resisting walls and ceilings around the stair, and an interlinked alarm and detection system. LACORS housing fire safety guidance is the recognised reference for the level of protection, and Part B of the Building Regulations applies to the building work.

Sound matters as well, because the lettings are separate households. Upgrading the floors between letting rooms with insulation and a new ceiling lowers complaints and helps the licence inspection. Energy is the other check: a Crouch End HMO let on tenancies must meet the MEES Regulations, which GOV.UK says have barred letting covered properties below E without a valid exemption since 1 April 2020. We carry out the insulation and heating work, and the assessor issues the EPC.

• Electrics extended to every bedroom, certified by a registered electrician
• Hot water sized for several sharers showering at once, with any gas work by a Gas Safe registered engineer
• Service holes sealed so each bedroom and the kitchen stay separate fire compartments
