HMO compliance works in Richmond upon Thames
HMO compliance in Richmond upon Thames, London
Lian Construction brings London rental properties up to HMO licensing standard, covering fire separation, protected escape routes, room sizes and amenity requirements. We work with landlords and letting agents across the capital on both mandatory and additional licensing schemes, surveying the property first, then pricing and scheduling the works needed to meet the conditions your local authority will check on inspection. This covers everything from a single fire door replacement to a full room-by-room reconfiguration of a converted house.
Richmond upon Thames overview
HMO compliance in Richmond upon Thames
Neighbouring Kingston, with a similar stock of period and riverside properties suited to full refurbishment and roof replacement work. Richmond upon Thames falls well within the South West London ground Lian Construction covers on a regular basis. For hmo compliance work in Richmond upon Thames, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Richmond upon Thames sits alongside Kingston and shares a similar mix of period and riverside properties. Expect a good number of Victorian and Edwardian terraces and villas, along with detached and semi-detached houses from the interwar years, many with later extensions and loft conversions added over time. Riverside stretches bring their own building types, older properties close to the water that were built before modern damp-proofing standards, along with some larger detached houses on wider plots. As with much of outer London, roofs on this older stock tend to be slate or clay tile, often original or close to it, with the valleys, flashings, and chimneys typically the first parts to need attention. Loft space is often tight in these properties, which makes roofline work and extensions a common route for adding usable space rather than moving house. This combination of age, riverside exposure, and a general preference among owners to extend and upgrade rather than relocate is what tends to drive demand for full refurbishment and roof replacement work in this part of south west London.
Given the age and type of housing stock, roof replacement and full refurbishment work tend to be steady sources of demand in Richmond upon Thames, much as they are in neighbouring Kingston. Owners of period and riverside properties are often dealing with roofs and structural elements that are decades past their original install, so replacement or significant repair becomes a practical necessity rather than a cosmetic choice. Riverside proximity can also mean a closer eye needed on damp and moisture-related issues, which often surface alongside roofing problems and get picked up during a wider refurbishment. Because this is an area where owners tend to invest in upgrading rather than moving, full refurbishment projects, spanning roofing, structural work, and internal modernisation, are a natural fit for the type of property found here. For a homeowner or landlord, this generally means budgeting for work that addresses the building as a whole rather than a single room, and choosing a contractor comfortable working on older properties where standard modern assumptions about structure, insulation, or roof pitch may not apply. Landlords with older buy-to-let stock in particular tend to prioritise roof condition, since it affects both letting standards and long-term maintenance costs.
With period property forming a significant part of the housing stock in this part of south west London, conservation area status and, in some cases, listed building designation are worth checking before starting work. Many outer London boroughs have conservation areas covering older residential streets, and these can affect what materials and roof profiles are acceptable, along with rules around extensions, dormers, and changes to the front of a property. Riverside locations sometimes carry additional planning considerations too. None of this means work cannot go ahead, but it usually means a bit more upfront checking with the local council before committing to a design or materials choice. As a general rule, it is worth confirming conservation area or listed status early, since it shapes what a roof replacement or extension can look like and how long approval might take.

Room sizes and amenity provision
Under the mandatory HMO licensing conditions that apply nationally, a bedroom occupied by one person aged 10 or over needs a minimum floor area of 6.51 sqm, two adults sharing a room need 10.22 sqm, and a room used by a single child under 10 needs at least 4.64 sqm. These are the baseline figures under the mandatory conditions of licence regulations, but they are a floor, not a target. Boroughs such as Newham, Croydon and Waltham Forest run additional or selective licensing schemes covering far more of their private rented stock, and some apply amenity standards on top of the mandatory conditions, so we treat the specific scheme covering the property as the reference document rather than assuming the national minimum is the final word. Where an existing room falls short, the fix depends on what's next to it. A boxroom or deep alcove next door can sometimes be absorbed by removing a stud partition and rebuilding the wall in a new position, which is usually the cheapest route if the structure allows it. Where there's no room to borrow space from, we look at whether a smaller room could be repurposed as a bathroom or second kitchen instead of a bedroom, which changes the room count the licence is assessed against. Amenity ratios get checked with the same scrutiny. Most councils expect one kitchen for up to five sharing tenants and one bathroom or WC for every four to five, with a minimum number of cooking rings, an oven, a sink and adequate worktop space scaled to occupancy. Inspectors count fittings, not intentions, so a landing with a kettle and microwave won't be accepted as a second kitchen. We've fitted second kitchens and shower rooms into understairs voids and former coal stores, converted boxrooms into ensuites, and split oversized double rooms into two compliant singles with a new stud wall, skirting and door set to match. Getting the room count, sizes and amenity ratio agreed against the correct licensing scheme before work starts is what stops a landlord paying twice for partition changes once an inspecting officer measures the finished rooms. Ceiling height matters too, and it's the detail people miss most often. Where a room has a sloped ceiling, typically a loft conversion or an attic bedroom in a Victorian terrace, only the area with a ceiling height of at least 1.5 metres usually counts toward the minimum floor area, so a room that looks large on paper can measure short once the sloped sections are excluded. We check this with a laser measure against the actual usable footprint rather than the overall room dimensions on a floor plan. Storage and refuse provision come up less often but do get raised at some inspections, particularly where a conversion has removed a garden shed or coal store that tenants previously used, and we can build in a lockable external store or internal cupboard space as part of the same programme where the council's scheme expects it.
Signs to look for
Do you need hmo compliance in Richmond upon Thames?
- Property is a converted Victorian terrace with three or more storeys sharing a single staircase and no fire-rated bedroom doors.
- Bedrooms measure close to or under 6.51 square metres, which may fail the minimum room size check at licensing inspection.
- Smoke alarms are battery-only rather than mains-wired and interlinked, which most councils flag as a fail at inspection.
- Kitchen or bathroom is shared by more tenants than the borough's amenity ratio allows for that number of occupants.

Questions
HMO compliance questions in Richmond upon Thames
How quickly can Lian start hmo compliance work in Richmond upon Thames?
Richmond upon Thames is part of our regular South West London coverage, so once we've surveyed the property we can usually confirm a start date quickly. Send the address and scope and we'll arrange the next step.
Do you cover all of Richmond upon Thames?
Yes. Richmond upon Thames falls within the area Lian Construction serves across Greater London.
How long does a full refurbishment of a period property usually take?
It varies quite a bit depending on the scope and what turns up once work starts, which is more likely on older properties. A single-room refurbishment might take a few weeks, while a full house refurbishment including roof work could run several months. Period properties sometimes reveal issues, such as damp, dated wiring, or structural quirks, once walls or roofs are opened up, so we try to build some flexibility into the programme rather than promise a fixed date too early.
Can you help with a full HMO conversion?
Yes. We can scope partition changes, fire separation, room sizes and amenities for a full HMO conversion project.
What's usually the biggest compliance gap you find in existing HMOs?
Fire separation is the most common issue: missing or degraded fire doors, unsealed penetrations through ceilings and walls, and escape routes that have been compromised by later alterations. Room sizes and amenity ratios can also fall short of current standards.
How long does it take to bring a non-compliant HMO up to standard?
It depends on the scale of the shortfall. A property needing fire doors, alarms and some fire-stopping can often be turned around in a matter of weeks, while a full conversion involving new partitions and room changes takes longer.
