HMO Conversions Epsom

An HMO conversion in Epsom turns a family house into a shared house, or brings an existing one up to licence standard. Epsom and Ewell Borough Council requires an HMO licence where five or more people forming at least two households live in a property, and the application must include a floor plan drawn to the council's own standards. That plan shows the fire strategy room by room, so what we build has to match it exactly. The landlord applies for the licence; we build to it.

For Epsom, 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 Surrey price follows a site visit. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Epsom: 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.

When an Epsom shared house needs a licence

Epsom and Ewell Borough Council requires an HMO licence where a property is occupied by five or more people forming at least two households. A licence is generally granted for a 5 year term, and fees are non refundable. The council states that it is an offence to operate a licensable HMO without a licence or valid exemption. That duty sits with the landlord, who applies, but it fixes the standard the building has to reach before the first tenant moves in.

Planning is a separate question from licensing. A change from a family house to a small shared house for three to six unrelated people, Class C4, is normally permitted development unless an Article 4 direction removes it. The owner or their agent confirms the position for the Epsom street concerned. A house for seven or more sharers is sui generis and needs planning permission. We start work once both the planning and the licensing route are clear.

Housing in Epsom

Count the homes in Epsom and you get about 16,290: 60% built since 1945, 23% between the wars and 15% before 1919, with flats at 35% and houses at 65%.

The Epsom HMO floor plan and why the build must match it

The floor plan is part of the licence application in Epsom, and it may be rejected without the right documents. The council's guidance requires room dimensions in metres and any ceiling height below 1.5 metres to be marked on the plan. The plans must show smoke detectors, call points, fire blankets, fire door ratings of 30 or 60 minutes, and windows. Any complex fire escape route has to be marked in red, with one A4 side per storey.

That makes the drawing a checklist for the build. We set out every detector, call point and fire door where the plan shows it, fit doors of the stated rating with the right frames, closers and seals, and label them. Where a loft or attic room has sloping ceilings, we measure the usable floor area before the plan is finalised. When the council's officer inspects the Epsom house, what stands in each room is what the plan says.

Room sizes, kitchens and bathrooms for sharers in Epsom

Bedroom sizes in a licensed HMO are set nationally. Since 1 October 2018 a mandatory licence requires at least 6.51 square metres for a room slept in by one adult and 10.22 square metres for two, and no room under 4.64 square metres may be used for sleeping at all. In an Epsom semi or detached house the small front bedroom over the hall is the room to check first, so the layout is tested against those figures before any walls move.

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.

Shared amenities follow the number of occupants. A house for five or six sharers needs a kitchen large enough for them, with enough sinks, cookers, worktop and storage, and enough bathrooms and WCs, separate where the numbers require. We plan the new bathroom or en suite positions around the existing soil stack where possible, because a new stack through a family house is a large part of the cost of an Epsom HMO conversion.

Certificates, sound and energy in an Epsom HMO

The application must include an Electrical Installation Condition Report from an inspection in the last 5 years and a current EPC. For an Epsom house being converted into an HMO, we programme the electrical work so the registered electrician can inspect and report once it is finished, and we complete insulation, heating and glazing work before the energy assessor visits. The paperwork then follows the build rather than chasing it.

Sharers keep different hours, so sound between rooms matters more than in a family house. We add insulation to the stud walls between bedrooms and lay a resilient layer under floors above bedrooms where the budget allows. Fire safety guidance for HMOs, the LACORS guide being the recognised reference, sets the detection, doors and escape a house of this size needs. That EPC must show E or better, since the minimum standard has covered existing lets as well as new ones from 1 April 2020, unless an exemption is registered.

• Separate WCs and wash basins to the amenity standard
• En-suite shower rooms added to bedrooms
• Sound lining to bedroom walls and party walls

Working With GS Renovation in Epsom

An HMO conversion is judged twice, once by the licensing officer and once by the people living in it. We work from the landlord's licence floor plan, build the fire doors, detection and escape exactly as drawn, and time the electrical inspection and EPC visit to the end of the works so the landlord's application goes in complete. A registered electrician issues the report and a registered gas engineer does any gas work. Abdelaaziz Saaid is your single contact from strip out to handover.
