HMO Conversions Royston

HMO conversion in Royston is a niche job, and a landlord should know the rules before buying. The work that arises here is likely to be a family house turned into a shared home, or an existing HMO brought up to licence standard. North Herts licenses any shared house with 5 or more unrelated tenants, and sets its own room size, kitchen and fire standards on top of the national rules.

For Royston, 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 (Mayfair Studio and LetCompliance, 2026); a Hertfordshire price follows a site visit. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Royston: 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 shared house in Royston: C3, C4 and larger HMOs

A small HMO in Royston does not usually need planning permission. Changing a family house (C3) to a shared house for three to six unrelated people (C4) is permitted development unless an Article 4 direction removes it. The Article 4 directions North Hertfordshire has published are two householder directions for the Hitchin and Stockens Green conservation areas and four town centre directions that remove the Class MA right. None of them covers the C3 to C4 change, but the owner's agent should confirm the current position with the council before buying.

Seven or more sharers is different. A large HMO is a sui generis use, so it needs full planning permission, and the council weighs it against Local Plan policies, including Policy D3 on neighbours' living conditions: daylight, overlooking and dominance. A house in Royston Conservation Area or a listed building brings its own consents for external changes such as new windows or fire escape stairs. The owner or their agent secures planning, and North Herts wants proof of it with the licence application.

North Herts HMO licensing for a shared house in Royston

North Herts requires an HMO licence for any private property rented as a shared house, flat or bedsit occupied by 5 or more unrelated tenants, however many storeys it has. That is the mandatory licence: five or more people forming two or more households. For a Royston house being converted to an HMO, the licence application is the owner's, and North Herts wants it in at least three months before the HMO starts operating. That lead time belongs at the front of the programme, not at the end of it.

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.

The application must include proof of planning permission where it is needed, any relevant building control documents, and a floor plan giving bedroom and shared room sizes in square metres with the positions of fire alarms, fire doors and emergency lighting. We produce a measured room schedule and collect the building control completion papers and the electrician's fire alarm details, so the owner's application describes what was actually built in the Royston property.

Room sizes and kitchens under the North Herts HMO standards in Royston

Above the national legal minimum of 6.51m2 for a single adult, the North Herts local HMO standard aims for a minimum of 8m2 for a single person's room. A room at the legal minimum is only accepted if the Licensing Team decides suitable communal space is available. One room units can be cut to no less than 6.51m2 at the inspecting officer's discretion, where a communal living room or kitchen with dining area exists. The national licence conditions also set 10.22m2 for two adults and bar any room under 4.64m2 from sleeping use. In a Royston terrace, that trade between bedroom count and shared living space is the first layout decision.

North Herts applies additional standards on amenities and fire precautions in larger properties. They require a full set of kitchen facilities for every five occupants, sited no more than one floor from the bedroom where practicable, and at least six power outlets above the worktops for every five occupiers sharing a kitchen. For a Royston house let to more than five people, that can mean a second full set of kitchen facilities. Keeping it within a floor of each bedroom can put a second kitchen upstairs, with the drainage, ventilation and electrical runs that go with it.

Fire doors, alarms, sound and energy in a Royston HMO

Fire safety is the core of an HMO conversion in Royston. Each bedroom opens onto a protected escape route with fire doors and self closers, the stair is enclosed, and a linked detection and alarm system covers the rooms and circulation. LACORS housing fire safety guidance is the recognised guide the licensing officers work from, and Part B applies where the work is building work. North Herts also sets additional fire precaution standards for larger properties, and the licence plan must show where alarms, fire doors and emergency lighting sit.

Sound and energy follow. Shared houses have more comings and goings, so better sound insulation in the floors and walls between lettings reduces complaints. A let house must also meet the minimum energy efficiency standard on its EPC, for existing tenancies as well as new ones, unless an exemption is registered, so loft insulation, heating controls and glazing belong in the same scope. In older Royston houses of clunch or soft brick, insulation is chosen so it does not trap moisture in the wall.

• Bedroom layouts checked against the national minimum room sizes
• Insulation and heating upgrades toward the minimum EPC for letting
• Extra shared bathrooms and shower rooms

Working With GS Renovation in Royston

An HMO is judged by the licensing team, not only by building control, so the build has to meet both. We set out bedrooms, kitchens and fire precautions to the North Herts standards, time the programme so the licence application can go in three months ahead, and hand the owner a measured schedule of room sizes and alarm positions. The landlord applies for the licence, a registered electrician certifies the alarm and wiring, and we coordinate the trades in between.
