HMO compliance works in Bromley
HMO compliance in Bromley, 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.
Bromley overview
HMO compliance in Bromley
South East London's largest borough by area, with established period housing and demand for roof replacement and general repairs. Bromley falls well within the South East London ground Lian Construction covers on a regular basis. For hmo compliance work in Bromley, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Bromley is South East London's largest borough by area, and that scale shows in the range of period housing across it. Expect a good deal of Victorian and Edwardian terraced and semi-detached houses in the more established residential pockets, alongside a substantial stock of 1920s and 1930s suburban semis, which is typical of outer London boroughs that grew up around expanding rail links in that era. There are also pockets of larger interwar and postwar detached houses, plus some later 20th-century infill and estate development filling in the gaps between older neighbourhoods. Roofs, chimneys, brickwork and rainwater goods on this older stock are now well past their original design life in many cases, which is a big part of why roof replacement and general repair work is in steady demand across the borough. Because Bromley covers such a wide area, the age and condition of housing can vary a lot street to street, so it is worth getting a property looked at individually rather than assuming what worked next door applies to your own roof or structure.
Given how much ground Bromley covers as London's largest borough, demand for roofing and general repair work is spread thinly across a wide area rather than concentrated in one or two hotspots. That has practical implications for homeowners: it can be harder to find a contractor who is genuinely local to your specific part of the borough and willing to travel efficiently, and lead times can stretch out during busy periods simply because tradespeople are covering more ground between jobs. With so much established period housing, a lot of the work coming through is reactive, roof repairs after storm damage, ongoing maintenance on ageing chimneys and guttering, and general fabric repairs on houses that were not built with modern weatherproofing standards in mind. For homeowners and landlords, this usually means being proactive pays off: getting a roof or exterior condition checked before a leak forces an emergency call tends to be cheaper and less disruptive. It is also worth asking any contractor how familiar they are with the specific area of Bromley you are in, since access, parking and the age profile of housing can differ quite a bit across such a large borough.
Given the amount of established period housing across Bromley, it is worth checking early whether a property sits within a conservation area, as is the case in parts of many outer London boroughs with older housing stock. This can affect what is permitted for roof coverings, chimney alterations, and visible external repairs, sometimes requiring like-for-like materials or additional consent even for straightforward repair work. Not every period property will be affected, and many repairs fall under permitted development, but it is not something to assume either way. If a property is listed or in a conservation area, it is sensible to confirm requirements with the local planning authority before work starts, since retrospective consent issues can cause delays and added cost. A contractor experienced with older properties should be able to flag likely restrictions early, but the homeowner remains responsible for confirming planning status.

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 Bromley?
- Landlord has received an improvement notice or licence refusal citing specific building works needed before re-application.
- Council has issued a licence renewal notice flagging fire doors or room sizes that no longer meet current standards.
- 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.

Questions
HMO compliance questions in Bromley
How quickly can Lian start hmo compliance work in Bromley?
Bromley is part of our regular South East 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 Bromley?
Yes. Bromley falls within the area Lian Construction serves across Greater London.
Do older Bromley properties need different repair approaches than newer builds?
Often, yes. Period houses were built with different materials and construction methods than modern homes, so repairs need to account for things like solid wall construction, original roofing materials, and older guttering systems that were not designed to modern standards. Using mismatched modern materials on an older property can sometimes cause more problems than it solves, so it is worth working with someone who has handled similar-age housing before, particularly for roofing and brickwork.
Do you handle the HMO licence application itself?
No, the licence application itself goes to the council and is normally handled directly by the landlord or their letting agent, since it involves personal declarations, fit and proper person checks, and financial details we're not party to. What we do is carry out the building work the licence conditions require, whether that's fire doors and alarms or a full reconfiguration, and we can provide photos, product certificates for fire doors and alarm systems, and a written specification of the completed works, which landlords typically need to submit alongside the application form or show an inspecting officer at the first licence visit. If a council asks a specific technical question about how a fire door or partition was constructed, we're happy to put that in writing directly.
Does converting a house into an HMO need planning permission?
It depends on the borough and the size of the HMO you're creating. Many parts of London sit within an Article 4 direction that removes permitted development rights for small HMOs housing up to six unrelated occupants, which means full planning permission is needed even for a fairly modest conversion that wouldn't otherwise need it. Larger HMOs housing seven or more occupants need planning permission everywhere in London regardless of Article 4 status, since that size falls outside permitted development entirely. Article 4 coverage varies block by block in some boroughs rather than applying borough-wide, so we can't confirm the position for a specific address without checking the local planning register. We'd recommend checking this before committing to a conversion, and we can flag anything relevant as part of our initial survey before any building work is priced.
What if the property only has one staircase, how do you deal with fire safety?
A single staircase serving all floors is common in converted Victorian and Edwardian terraces, and it effectively becomes the whole fire strategy for the property since it's the only way out from the upper floors. That usually means every door opening onto the stair, bedroom doors included, needs to be an FD30s fire door with intumescent strips and cold smoke seals, the stair enclosure itself needs to be built from fire-resisting construction from ground floor to top floor, and any cupboards, meter boxes or service risers opening onto it need to be fire-stopped and fitted with fire-rated doors of their own. On larger three-storey conversions, some fire strategies also call for a heat or smoke detector positioned directly on the stair and tied into the interlinked mains alarm system, which we'd identify and position correctly during the initial survey rather than as an afterthought.
