Large Victorian and Edwardian housing stock with almost no dedicated roofing or refurbishment coverage from established competitors. Lewisham sits around 12 miles from our Kingston upon Thames base, well inside the South London ground we cover on a regular basis. For hmo compliance work in Lewisham, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Lewisham's housing stock is dominated by Victorian and Edwardian terraces and bay-fronted semis, typical of the wave of building that spread across inner and near-inner London boroughs from the 1870s through to the 1910s. Expect solid brick external walls, slate or clay-tiled pitched roofs, timber sash windows, and party wall arrangements shared between neighbouring terraced properties. Many homes will have seen later alterations, loft conversions, rear extensions, or conversion into flats, which adds complexity when repair or refurbishment work touches roofline, guttering, or shared structural elements. Original slate roofing on housing of this age is now well over a century old in many cases, and a proportion will have already been part-replaced with concrete or synthetic tiles at some point, often inconsistently. This mix of original and patched-up roofing is common across older London housing stock generally. Bay windows, decorative brickwork, and chimney stacks typical of the period also mean roofing and refurbishment work often needs to account for period detailing rather than treating every job as a standard modern re-roof.
With such a large concentration of Victorian and Edwardian property, Lewisham has an ongoing and fairly predictable need for roof repair, re-roofing, and general refurbishment work, simply because housing stock of this age reaches the point where original materials need attention or full replacement. What stands out is the apparent gap in dedicated roofing and refurbishment coverage from established contractors in the area. For homeowners and landlords, that generally translates into longer waits for quotes, more reliance on general builders rather than roofing specialists, and less local choice when comparing contractors who actually focus on period property work. Landlords managing older converted or rented properties face this more acutely, since compliance-driven repairs (damp, roof leaks, structural issues) don't wait for convenient timing. A borough with this much ageing housing stock and limited specialist coverage tends to mean steady, ongoing demand rather than one-off spikes, which matters for anyone planning maintenance or budgeting for future works. It also means homeowners may need to look slightly further afield or be more selective when vetting who they bring in, since the usual density of local roofing specialists seen in some other London boroughs doesn't appear to be there yet.
Victorian and Edwardian terraces of the kind common in Lewisham are frequently found within conservation areas across London, a pattern seen widely in boroughs with this era of housing stock. Where a property sits inside a conservation area, roof alterations, changes to visible materials, or additions like rooflights and dormers may need planning permission rather than falling under permitted development. Even outside a conservation area, terraced and semi-detached houses of this age can have restricted permitted development rights depending on prior extensions or alterations already carried out. It's worth checking a property's specific planning history and conservation status with the local authority before finalising scope, particularly for anything visible from the street or affecting a shared roofline with a neighbouring property. This isn't unique to Lewisham, but it is a practical step worth building into any refurbishment timeline for period housing of this type.
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.
Electrics, gas and interlinked alarm systems
HMO licence conditions extend well beyond the building fabric into the property's electrical and gas installations, and these get checked alongside fire separation at both application and renewal. Councils generally expect a current Electrical Installation Condition Report showing no outstanding C1 or C2 faults, a valid annual Gas Safety Record for any gas appliances and flues, and a fire detection and alarm system that's mains-wired with battery back-up and interlinked across the whole property, typically specified to BS 5839-6 grade D LD2 or LD3 coverage depending on the layout and number of storeys. A grade D system means every alarm is powered from the mains with a tamper-proof standby battery, and LD2 coverage extends beyond just escape routes into rooms presenting the highest fire risk, usually kitchens and living rooms.
We coordinate the electrical and alarm work alongside the fire separation and partition works rather than treating it as a separate visit, because running new alarm cabling between floors usually means lifting the same floorboards or opening the same ceiling voids needed for fire-stopping, and it's more efficient and less disruptive to tenants to do both in one pass through a room. Where an EICR flags an old rewirable fuse board, missing RCD protection, degraded cross-bonding or unearthed lighting circuits, which is common in properties that haven't been rewired since a 1980s or 1990s conversion, we bring in a qualified electrician to remedy those items alongside the room works rather than handing back a property with a partial fix that fails on the electrical side.
Emergency lighting on escape routes is sometimes required for larger or more complex HMOs, particularly where a stairwell or corridor relies on borrowed light that's since been blocked by an internal alteration, and fire strategies for bigger properties can also call for heat detectors in kitchens rather than smoke detectors, since normal cooking activity would otherwise trigger false alarms. We flag any of this during the initial survey rather than after installation, because retrofitting battery packs, conduit or cabling into a ceiling that's already been boarded and skimmed costs considerably more than fitting it during the first pass through the property.
Kitchen and bathroom extraction is another area that gets missed until an inspection picks it up. Building Regulations expect mechanical extraction ducted to external air in any kitchen and bathroom, not just an internal fan recirculating steam back into the room, and where a new kitchen or shower room is being added into an internal space with no external wall nearby, ducting it out can mean running it through a neighbouring room's void or up through a loft, which needs planning at the design stage rather than once tiling is finished. We also check portable appliance testing on any landlord-supplied white goods in shared kitchens, since PAT records are something inspecting officers can ask to see alongside the EICR and gas certificate.
