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.
Hackney overview
HMO compliance in Hackney
148 Checkatrade listings but a fragmented market with no dominant brand — heavy Article 4 planning activity and steady gentrification-driven refurbishment demand. Hackney falls well within the East London ground Lian Construction covers on a regular basis. For hmo compliance work in Hackney, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Hackney's housing stock is dominated by Victorian and Edwardian terraces, many split into flats, alongside a good number of converted warehouses and ex-industrial buildings from the borough's manufacturing past. There's also a substantial amount of post-war council housing, ranging from low-rise blocks to larger estates, sitting close to streets of period terraces. This mix means the borough has a wide spread of jobs for contractors, from internal reconfiguration of Victorian conversions to communal repairs on estate blocks. Given the heavy Article 4 planning activity referenced locally, a meaningful share of this stock sits within conservation areas, where the usual Victorian and Edwardian terrace features (sash windows, slate roofs, original brick facades, decorative frontages) are more tightly protected than elsewhere in London. As with much of inner London, solid wall construction is common, which has implications for insulation and damp work. Property owners taking on refurbishment in Hackney are often dealing with buildings that have already been altered more than once, so matching existing detailing and working around previous non-standard interventions is a regular part of the job here.
Hackney shows a high volume of construction activity on Checkatrade (148 listings) but no single contractor or brand has established a clear lead, which makes the market fragmented. For homeowners and landlords, this generally means more choice but also more variability in quality and pricing, so getting quotes from a few established firms and checking references carefully is worth the extra time. The borough's heavy Article 4 planning activity adds another layer: permitted development rights are withdrawn in many areas, so alterations that would be straightforward elsewhere often need a full planning application first. This tends to lengthen project timelines and makes it more important to work with a contractor who understands local planning requirements rather than just the build itself. On top of that, steady gentrification-driven refurbishment demand means many properties are being upgraded to modern standards, from kitchen and bathroom renovations to loft conversions and full internal refits, often as part of a wider push to bring older housing stock up to current expectations. Landlords in particular are likely refurbishing between tenancies or ahead of resale, so demand for reliable, planning-aware contractors in Hackney tends to stay consistent rather than seasonal.
Given the level of Article 4 planning activity in Hackney, many homeowners will find that permitted development rights, which normally allow smaller works like some rear extensions, roof alterations or replacement windows without planning permission, have been removed in their area. This means a full planning application is often required even for changes that would be minor elsewhere in London. If your property sits within a conservation area, expect additional scrutiny on materials and appearance, particularly for anything visible from the street, such as windows, doors, roofing materials and front boundary treatments. It's worth checking your property's specific Article 4 status and conservation area designation with the council before finalising any design, since this affects both timeline and what materials or approaches are realistically achievable.

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.
What drives the cost of HMO compliance work
Pricing an HMO compliance job depends far more on how far the property is from standard than on its overall size. A property that only needs fire doors, interlinked alarms and some fire-stopping to ceiling and floor voids is a relatively contained job, and can often be costed and scheduled within a matter of weeks once survey and pricing are agreed. Where partition walls need to move to correct undersized rooms, or a bathroom or second kitchen needs to be added from scratch, costs rise quickly once plumbing, mechanical extraction, electrical first and second fix, plastering and matching the existing finish are all factored in.
Structural changes add both cost and time for building control sign-off. Removing a load-bearing wall to reconfigure a floor and installing a steel beam to carry the load above, or altering a staircase to improve the escape route, both need calculations from a structural engineer and inspection at set stages, which extends the programme even where the physical work itself is quick. Older fire doors are rarely a straightforward swap: many original door openings in Victorian and Edwardian houses are undersized, out of square, or have settled over a century of movement, so fitting a certified FD30s door set often means adjusting the lining, and sometimes taking back a course or two of brickwork or building up the reveal, rather than dropping a new door into the existing frame.
Access matters more than people expect. A mid-terrace property with no side access means materials, including plasterboard and fire-rated stud timber, have to go through the house, which slows the job compared with a property that has rear access or off-street parking directly outside. We also factor in whether tenants remain in situ, since working around an occupied property with notice periods and room-by-room access takes longer than a vacant one where several trades can work simultaneously.
We survey the property first and price against the specific list of works the applicable licensing conditions require, rather than quoting a blanket day rate or a per-room average, because two outwardly similar terraced houses on the same street can need very different amounts of work depending on what's already been done to them, when they were last rewired, and how the loft and floor voids were left by previous alterations.
Statutory costs sit alongside the building work itself and are worth budgeting for separately. A structural engineer's calculations for a steel beam, a building control application fee, and in some cases a party wall agreement with a neighbour if work touches a shared wall or foundation, can add a few hundred to a couple of thousand pounds before a single wall is opened up, depending on the scope. Scaffolding or a tower for external fire door work, cladding repairs above ground floor level, or access to a rear elevation without side access, is a further cost that's easy to overlook when comparing quotes that don't specify access equipment separately from labour and materials.

Signs to look for
Do you need hmo compliance in Hackney?
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.
Smoke alarms are battery-only rather than mains-wired and interlinked, which most councils flag as a fail at inspection.

Questions
HMO compliance questions in Hackney
How quickly can Lian start hmo compliance work in Hackney?
Hackney is part of our regular 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 Hackney?
Yes. Hackney falls within the area Lian Construction serves across Greater London.
Do I need planning permission for a loft conversion in Hackney?
It depends on your specific street and whether an Article 4 direction applies to your property. Given how widespread Article 4 activity is across Hackney, there's a reasonable chance permitted development rights have been restricted, meaning you'd need full planning permission even for a fairly standard loft conversion. We'd always recommend checking with the council or getting a planning consultant to confirm before committing to a design, as it affects both cost and timeline.
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.
What are red flags for landlords to check when hiring an HMO compliance contractor?
A few things are worth checking. Make sure the quote is priced against your specific borough's published HMO scheme rather than a generic checklist, since room sizes, amenity ratios and licensing conditions vary by borough and some run additional or selective licensing with tighter standards. Ask whether statutory costs, a structural engineer's calculations, a building control fee, a party wall agreement where relevant, are included in the quote or missing from it, since a suspiciously low figure sometimes leaves these out only for them to appear later. Ask for photographic evidence, product certificates for fire doors and alarm systems, and a written specification of completed works, since that's what you'll need for a licence application or an inspecting officer. Be wary of a blanket per-room day rate given without a proper survey, and treat sudden availability from a contractor who can start immediately with some caution.
