Are FD30 fire doors legally required in an HMO?

Yes, in practical terms. The Regulatory Reform (Fire Safety) Order 2005 places a duty on the Responsible Person to maintain general fire precautions, including the structural fire protection of the escape route. In an HMO that means FD30 doors on every bedroom, on the kitchen and on any cellar or cupboard with a utility meter. The exact schedule is set by the fire-risk assessment carried out under PAS 79, and HMO licence conditions issued by London boroughs almost always specify FD30 minimum on these rooms. A door that opens onto a protected escape route in an HMO and is not FD30 is a licence breach and a fail at the next council inspection.

Can I keep my original Victorian panel doors in an HMO?

No, not as fire doors. Victorian and Edwardian panel doors are constructed with thin panels set into rebated stiles, and the panel joint fails within five to ten minutes of fire exposure — well short of the 30-minute FD30 rating. There is no compliant retrofit. Intumescent paint, applied panels, additional layers of plywood — none of these convert a panel door into a certified FD30 assembly. The compliant route is to remove the original door, retain it carefully if it has heritage value, and install a certified FD30 blank. If the property is listed, the council's conservation team will accept a paint-matched and beaded FD30 door that visually echoes the original — speak to the borough's conservation officer before specifying the replacement.

How often do FD30 doors need inspecting?

Under the Regulatory Reform (Fire Safety) Order 2005 the Responsible Person must inspect fire doors at intervals appropriate to the use of the building. Industry guidance from the Fire Door Inspection Scheme (FDIS) recommends a competent inspection every six months for HMOs and every twelve months for self-contained flats with shared circulation. London-borough HMO licence schedules typically require an annual fire-door inspection report alongside the BS 5839-6 commissioning certificate at licence renewal. A quick visual self-check by the landlord — seals intact, hinges tight, closer functioning, threshold gap under 4 mm — should be a monthly task between formal inspections.

Do fire doors need self-closers in every room?

Self-closers are mandatory on any kitchen door in an HMO and on any door that opens directly onto the protected escape route. Whether they are required on every bedroom door depends on the property's fire-risk assessment and on the London-borough HMO licence schedule. Several boroughs — including the larger central-London licensing authorities — have moved to requiring overhead closers on every bedroom door in HMOs as a licence condition. Even where not strictly required, our standard install on a licensed HMO includes a Briton or Dorma overhead closer on every bedroom door because the certification only holds when the door is closed in a fire, and a door wedged open by a tenant is no door at all.

How much does an FD30 door installation cost in London?

Across London in 2026 expect £450 to £800 per door for a full supply-and-fit on an FD30 door including the certified blank, frame adjustment or replacement, intumescent strip and cold-smoke seal set, three CE-marked hinges, an overhead self-closer, certified lever furniture, a thumb-turn deadlock and a fire-door installation certificate. Premium veneered or paint-grade door blanks push the upper end of that range. Stripping cost by buying a non-certified door blank from a builders' merchant typically saves £80 to £120 per door and voids the buildings insurance policy on the entire property — that is the trade we never recommend making.

FD30 Fire Doors: HMO Landlord Checklist 2026

What FD30 fire doors must do — certification, intumescent strips, hinges, self-closers. Full HMO landlord checklist for 2026 inspections.

An FD30 fire door is the single most visible piece of fire safety in any London HMO — and the one we see fitted wrong more often than any other. The number 30 is the minutes the door assembly will hold back fire and smoke when tested to BS 476-22 or BS EN 1634-1. Those 30 minutes are what give your tenants time to walk down the stairs and out of the building before the corridor is impassable, and they are what the fire-risk assessor, the council HMO licensing officer and the buildings insurer will all measure against.

The catch is that the rating applies to the whole assembly — the leaf, the frame, the intumescent strips, the cold-smoke seals, the hinges, the closer, the lock and the threshold gap — not to the door blank in isolation. Replace any one of those components with the wrong part and the certification collapses. This page is the checklist we run a London HMO portfolio against before licence renewal, and it is the same checklist we use at the inspection visits that follow a tenant complaint.

What FD30 Actually Means

FD30 is a fire-resistance rating issued against a tested door assembly. The "FD" prefix is the abbreviation used in BS 8214 (the code of practice for timber-based fire-door assemblies). The "30" is the minutes of integrity — how long the door, frame and seals will hold back fire and smoke under a furnace test that ramps temperature to roughly 840°C over the test period. FD60 is the 60-minute equivalent, used on stair-enclosure doors in taller HMOs and on plant rooms; FD20 is largely obsolete in modern UK practice.

The FD30 rating is awarded by a UKAS-accredited third-party certification scheme — the four you will see on door labels in the UK are BWF-Certifire, BM TRADA Q-Mark, IFCC and Exova Warringtonfire. The certification is specific to that exact combination of leaf, frame, intumescents, hinges and closer that was tested. Swap any one component for an uncertified equivalent and the certification no longer applies.

Where FD30 Doors Are Required in an HMO

The authoritative answer for any property is the fire-risk assessment carried out under PAS 79 by a competent assessor — but in the absence of an assessment, these are the rooms a London HMO will need FD30 on:

Every bedroom door — Protects the sleeping tenant from a corridor fire and protects the corridor from a fire that starts inside a bedroom (the second-most-common origin point after the kitchen).
The kitchen door — The single highest-risk room in any HMO. Always FD30, always with a self-closer, frequently FD30S (the S denoting an enhanced smoke seal).
Any cellar or cupboard housing the gas meter, electricity meter or boiler — Utility cupboards are a recurring ignition point and the FRA will almost always specify FD30 even if the cupboard is rarely entered.
The living room — Required where the living room opens directly onto the protected escape route, which is the typical layout in a converted Victorian terrace HMO.
Storage cupboards on the escape route — Including the under-stairs cupboard, which historically housed the gas meter and is now usually a storage void.

HMOs of three or more storeys may also require FD60 doors on the stair enclosure at each landing — this is set by the fire-risk assessment and by the HMO licence schedule. Our HMO fire risk assessment for London service produces the door-by-door schedule the licence application needs.

What Makes a Door FD30 — Certification and Construction

An FD30 door blank is fundamentally a solid-core construction — typically a chipboard, flaxboard or particleboard core 44 mm thick (compared to the 35 mm of a domestic-grade internal door), faced with hardwood lippings on the long edges and a hardwood or veneer skin on both faces. The core mass and the lippings are what give the assembly its 30 minutes of integrity. A hollow-core door, a moulded-panel door or a glazed door without certified FR-glass cannot achieve FD30 regardless of how it is treated.

Identification is straightforward when it is correct. A certified FD30 door blank carries a permanent label embedded in the top edge or the hanging edge — visible only when the door is open. The label identifies the manufacturer, the certification scheme (BWF-Certifire, BM TRADA Q-Mark, IFCC or Exova), the certificate number and the fire-resistance rating. The label is plastic or metal and is intended to survive painting, decoration and the door's full service life. No label means no certification — and a doorset with no label is treated by the council inspector as a non-FD30 door, regardless of how convincing it looks.

The certification covers the door assembly, not just the blank. The certificate will specify the permitted frame timber and thickness, the maximum and minimum threshold gap, the permitted intumescent strip and smoke-seal range, the permitted hinges (manufacturer, model, size and quantity), the permitted self-closer (where required) and the permitted glazing. Substitute any item outside the certificate's permitted range and the door is no longer certified, even if every individual part appears to be a fire-rated component.

Intumescent Strips and Cold-Smoke Seals

Intumescent strips are the strips of fire-reactive material set into a routed groove in the door edge or the frame. Under fire conditions the intumescent expands to roughly 25 times its original volume, sealing the gap between door and frame and preventing flame and hot gas from passing through. Cold-smoke seals are the brush or fin seals — sometimes integrated into the same carrier as the intumescent — that seal against cold smoke at ambient temperature, before the intumescent has activated. Most modern FD30 doors use a combination strip with both functions in a single carrier.

The inspection points are simple but routinely missed:

Continuous around three sides — The strip must be continuous along the top edge of the door (or the head of the frame) and down both jambs. No gaps, no kinked sections, no missing portions where a hinge or lock has been cut through.
Not painted over — Intumescents fail to expand when smothered in gloss paint. Strips that have been overpainted during a redecoration are an automatic failure point and need replacement before the door is re-certified.
Threshold gap — The gap between the bottom edge of the door and the finished floor must not exceed 4 mm across the door's full width. Larger gaps need a threshold plate, a drop-seal or a replacement door blank.
Side and head gaps — The gap between door edge and frame should be in the range 2–4 mm. Tighter than 2 mm and the door binds; wider than 4 mm and the intumescent cannot bridge the gap in time.

Hinges — CE-Marked, Steel, Three Per Leaf

A standard FD30 door needs a minimum of three CE-marked steel hinges per leaf, sized to the door's weight class. Heavier doors and doors with closers fitted often need four hinges. The hinges must be the make, model and size listed on the door manufacturer's certification — substitute a "fire-rated" hinge from a different manufacturer and the certification does not apply.

The most frequent failure point we attend in London HMOs is decorative brass or bronze hinges with concealed screws fitted to a door blank during a tasteful refurbishment. Pretty brass hinges almost never meet the load and intumescent-pad requirements of an FD30 assembly. The compliant replacement is a polished or satin steel hinge that visually resembles brass but carries the required CE mark and load rating.

Self-Closers — Where Required and Which Type

A self-closer is the device that returns the door to its closed position after every use, ensuring the door is shut when fire breaks out. The two main types in London HMO use are overhead hydraulic closers (the surface-mounted boxes manufactured by Briton, Dorma, GEZE and others) and concealed spring closers (such as the Perko Powermatic, fitted into the door edge).

The standard London HMO licence schedule requires self-closers on:

All kitchen doors — Without exception.
Any door opening directly onto a protected escape route — The corridor or stairwell that leads to the final exit.
Bedroom doors in many London boroughs — Check the licence schedule; an increasing number of boroughs now require closers on every let bedroom door.

The closer must be installed and adjusted to fully close the door from any open angle, including the 10° to 15° "creep" angle a tenant typically leaves a door at when carrying laundry through. A closer that does not pull the door fully shut into the latch is functionally absent.

Glazing — Pyrobel, Pyroclear and Size Limits

An FD30 door may include a vision panel, but the glazing must be a certified fire-resistant glass — typically Pyrobel (Glaverbel) or Pyroclear (Pyroguard) — set into a certified intumescent glazing system. Ordinary toughened glass, ordinary wired glass and ordinary laminated glass are not fire-rated and immediately void the door's certification.

The size of the glazed panel is limited by the door's certificate, typically to a maximum of roughly 30% of the door area, with specific maxima for height and width. The glazing system — beads, intumescent tape and fixings — must be the system listed on the certificate. Replacing a damaged pane with a sheet of ordinary glass during a refurbishment is one of the more expensive mistakes we attend, because the entire glazing assembly usually has to be remade.

Locks, Handles and Escape Route Egress

Fire doors on an HMO escape route must allow rapid egress without a key. The standard ironmongery package is:

Lever-on-rose or lever-on-backplate handles — Allowing the door to be opened with a single downward movement. Knob furniture (round knobs) is non-compliant on an escape route because it cannot be operated reliably with wet, soapy or injured hands.
Thumb-turn deadlock — A deadlock operated by a key from the corridor side and a thumb-turn from the room side. The thumb-turn allows the occupant to open the door from inside without searching for a key during a fire.
Intumescent pads behind every cut-out — Lock body, latch keep, hinges and any other through-fixing must have an intumescent pad behind it to maintain the door's fire integrity around the cut.

Cylinder-only deadlocks that require a key on both sides are an immediate fail on an HMO bedroom door and are the failure we cite most often on first-attendance inspections.

Common Inspection Failures We See

In rough order of frequency on a first-visit HMO inspection across the 32 London boroughs:

Pretty doors that are not FD30 — Original Victorian panel doors, modern moulded-panel doors and reclaimed Edwardian doors fitted as bedroom doors during a tasteful refurbishment. No label, no certification, no compliance.
Intumescent strips painted over — A decorator has rolled gloss paint over the seals during a redecoration. The intumescent cannot expand under fire and the door fails its rating.
Wrong hinges — Decorative brass hinges with concealed screws or unmarked "fire-rated" hinges of unknown provenance. The fire-door certificate names a specific hinge — anything else is uncertified.
Closer removed by tenant — Overhead closer disconnected, removed and stored in a cupboard because the tenant found it inconvenient. The door no longer closes itself and the certification is moot.
Threshold gap exceeding 4 mm — Often the result of new flooring being laid without the door being re-trimmed or re-hung. Wide threshold gaps allow smoke transfer before the intumescent has activated.
Cylinder-only deadlocks on bedroom doors — A landlord-fitted deadlock that needs a key on both sides. Tenant cannot escape in a fire without finding the key.
No installation certificate on file — Doors physically present and apparently correct, but no installation certificate exists. The landlord cannot demonstrate compliance and the council treats the doors as uncertified.

Items 1, 2 and 7 together account for roughly two-thirds of the FD30 inspection failures we attend each year. None of them are expensive to fix when caught early. All of them are expensive to fix after a serious incident.

Cost Guide — London 2026

Indicative London 2026 prices for FD30 supply and install on a typical HMO bedroom door:

FD30 door blank only — £150 to £280 depending on facing (paint-grade, white-primed, oak-veneered, walnut-veneered). Premium veneered and lipped blanks push the upper end. We supply BWF-Certifire and BM TRADA Q-Mark blanks as standard.
Fitting labour — £180 to £280 per door, including hanging, intumescent strip fit, frame adjustment or replacement, threshold trim and certificate paperwork. Listed-building work and access-restricted top-floor rooms sit at the upper end.
Ironmongery set — £80 to £180 per door for three CE-marked steel hinges, lever-on-rose handles, thumb-turn deadlock, intumescent pads and a Briton or Dorma overhead closer.
Full supply-and-fit including certificate — £450 to £800 per door. Most central-London HMO portfolios sit at the £550 to £700 per door mark.

The trade that voids your buildings insurance — and the one we never recommend — is buying a non-certified door blank from a high-street builders' merchant. The blank saves £80 to £120, the certification is gone, and the insurer's small print on the policy becomes a route for them to walk away from a claim. The £450 to £800 per door is the cheapest line on the entire HMO licence schedule when judged against the value of the certification it buys you.
