HMO Conversions Kew

HMO conversion in Kew means turning a family house into a shared house for unrelated tenants, or upgrading an existing HMO to meet Richmond's licence standards. The stock gives the raw material, with 57% of homes here houses and 25% semi-detached or detached, but the rules decide the layout. Richmond applies the mandatory HMO licence to five or more occupiers in two or more households, and publishes its own amenity standards. We build kitchens, bathrooms, fire protection and room layouts to the licence and consent the landlord holds.

In Kew, 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 Kew: 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 Kew HMO: C3, C4 and sui generis

Richmond says planning permission is needed for HMOs occupied by seven or more people. The London Plan glossary treats HMOs for three to six people as Use Class C4 and HMOs for more than six as sui generis. Nationally, Class L permitted development allows a change from a C3 house to a C4 HMO, but not the use of one former house as two or more separate C4 HMOs. The landlord confirms the planning position for the Kew house; we build to it.

An Article 4 Direction can remove the Class L right, and the London Plan asks boroughs considering one for changes between C3 and C4 to weigh the strategic as well as local importance of HMOs. Before buying or converting in Kew, a landlord should check with Richmond whether any such direction covers the street. Richmond also offers 90-minute in-depth HMO pre-application advice, which is a sensible step before a layout is drawn and priced.

Licensing a shared house in Kew

Richmond requires an HMO licence where a house or flat has five or more occupiers forming two or more separate households who share amenities. GOV.UK defines an HMO more widely as a property rented out by at least 3 people who are not from 1 household but share facilities such as the bathroom and kitchen. It also says a smaller HMO may still need a licence depending on the council area. A flat in a purpose-built block of three or more flats sits outside mandatory licensing, though an additional scheme can reach it. The landlord applies for the licence.

Our part is the building the licence describes. Renting out an unlicensed HMO can lead to an unlimited fine, so a Kew landlord usually wants the works finished and inspected before tenants move in. The national minimum bedroom sizes are mandatory licence conditions in England: 6.51 square metres for one adult and 10.22 for two, and no room under 4.64 square metres may be used for sleeping. They are measured on usable floor area: fixed boxing and built-in cupboards reduce it, a door swing does not. We set out every bedroom against those minimums at first fix.

Richmond's amenity standards applied to a Kew house

Richmond publishes Minimum Amenities Standards for Houses in Multiple Occupation 2020 and says they are minimums, not the ideal state. They set a kitchen of at least 7 m2, or 11 m2 as a kitchen diner, with a worktop of at least 1500 x 600 mm. A living room needs at least 11m2, or 18m2 combined with the kitchen. In a Kew terrace the back addition can be too small for a shared kitchen, which pushes it into a front room.

Two further rules change the layout of an older Kew house. Where a bedsit has its own kitchen facilities, Richmond adds 3.5m2 to the minimum bedroom size, and any floor area under a ceiling height of 1.5m is disregarded. A top floor room under a sloping roof can therefore lose much of its counted area. We measure those rooms before the layout is fixed, and plan bathroom and WC numbers to the occupancy the licence will allow.

Fire safety, sound and energy in a Kew HMO

Fire protection is the core of an HMO conversion. Bedrooms open onto a protected escape route, so doors to rooms off the stair become fire doors with self closers. The stair enclosure is lined to the fire rating required, and linked smoke and heat detection is fitted to the standard the council sets. LACORS housing fire safety guidance is the recognised guide, and building control checks Part B where the work is notifiable. In a Kew house with a lath ceiling under the stair, that ceiling is often renewed.

Shared houses are noisy, so we add sound insulation to walls and floors between bedrooms where the layout puts one person's room over another's. Energy is the other licence point. Where the house is covered by the MEES Regulations, a landlord cannot let it with an EPC below E without a valid exemption, as has applied since 1 April 2020. An HMO conversion in Kew should therefore include insulation, heating controls and efficient hot water sized for the number of tenants.

• Small HMO conversions for three to six sharers
• Service holes sealed so each bedroom and the kitchen stay separate fire compartments
• Emergency lighting on the escape route where the house needs it

Why Choose GS Renovation in Kew

HMO work is judged by an inspector against written standards, so we build to them line by line. We check room areas and ceiling heights against Richmond's standards before first fix, keep fire stopping and doors open for inspection, and hand the landlord the certificates the licence application asks for. A registered electrician certifies the electrics and the alarm installer commissions the fire detection, and gas work is done by an engineer on the Gas Safe Register. One point of contact runs the job, and the quote is fixed after a site visit.
