Fire door compliance,
built around the commercial lease.

A commercial office is a portfolio of contracts as much as a portfolio of doors. The Fire Safety Order sets the Responsible Person duty; the lease decides who carries the operational obligation, common parts versus demised parts, FRI versus internal repairing. DoorTRACE configures around the lease structure, the multi-let coordination reality, and the institutional reporting context your asset manager actually expects.

The legal landscape

The regulations every commercial office works to.

Commercial offices sit firmly inside the non-domestic regulatory stack. The Fire Safety Order names the Responsible Person; workplace and equality legislation sit alongside it; British Standards set the inspection methodology. The complexity is not in which laws apply, but in which party to the lease actually carries each duty.

FSO 2005

Fire Safety Order 2005

Article 8 imposes the Responsible Person duty across every non-domestic part of the office building. Common parts almost always rest with the landlord; demised parts depend on the lease. Article 9 requires a documented fire risk assessment, reviewed regularly, available to the enforcing authority.

WHSW 1992

Workplace (Health, Safety and Welfare) Regulations 1992

Sets the workplace standards for means of escape, signage, lighting, and the maintenance of safe routes. Sits alongside the FSO and is enforced by the Health and Safety Executive in practice. Fire door condition is squarely inside this regulation.

HSWA 1974

Health and Safety at Work Act 1974

The parent legislation. Section 3 imposes a duty on every employer and self-employed person to conduct their undertaking without exposing third parties to risk. Office landlords carry duties to occupiers, occupiers carry duties to their staff and visitors.

EQA 2010

Equality Act 2010 (PEEPs)

Reasonable adjustments include Personal Emergency Evacuation Plans for disabled occupants, visitors, and customers. Fire door operating force, ironmongery type, and signage all fall under the access duty. A PEEP cannot work if the fire doors on the route do not.

BS 9999

BS 9999:2017

Code of practice for fire safety in design and management of buildings. The framework BS 8214 inspection routines reference for door performance, hardware specification, and operational fire safety across commercial office buildings.

BS 8214

BS 8214:2016

Code of practice for fire door assemblies. The technical inspection standard DoorTRACE checklists follow as default, and the methodology competent inspectors apply across UK commercial office estates.

Sector challenges

Why office fire safety is governed by the lease.

The commercial office is the only sector where the operating duty for fire safety is split by contract rather than by statute. Common parts belong to the landlord. Demised parts belong to the occupier. Fit-outs, dilapidations, and lease events constantly redraw the line. Generic compliance software does not model any of that.

I.

Landlord versus occupier duty split

The Fire Safety Order names a Responsible Person, but in a multi-let office the lease decides who that is in practice. Common parts rest with the landlord. Demised parts depend on the lease type: FRI typically puts maintenance on the occupier, internal repairing splits it. Inspection workflows have to respect that split or they generate the wrong evidence for the wrong party.

II.

Multi-let coordination across occupiers

A Class A office building has ten to thirty occupiers under separate leases. The managing agent coordinates fire safety across all of them: communal cycles for the landlord, occupier reports for each tenant, evidence for the building fire risk assessment. Each occupier wants their own slice of the compliance picture for their internal audit.

III.

Fit-out and dilapidations cycles

Every five to fifteen years occupiers change. Each fit-out breaches compartmentation and rebuilds it. Each dilapidations exit raises questions about what the outgoing occupier installed and what they must reinstate. A five-year fire door compliance history per demise is a routine ask in a dilaps negotiation, and the answer needs to be a clean export.

IV.

Institutional reporting and ESG context

Class A offices are owned by REITs, pension funds, sovereign wealth funds. Fire safety sits alongside MEES, EPC, Net Zero pathways, and GRESB scoring in the asset management report. The investment committee that approves capex looks at fire safety the same way it looks at energy. The compliance pack has to be institutional-grade, not just operational.

How we help

Built around how multi-let offices actually operate.

DoorTRACE configures around the commercial office reality: a lease-driven duty split, multi-let occupier coordination, constant fit-out and dilapidations activity, and the institutional reporting cadence your asset manager and sustainability committee actually need.

Lease-aware cadence

Inspection cycles aligned to the lease structure.

Inspection cadence configured per building, per zone, per occupier demise. Common parts on the landlord cycle. Demised floors on the occupier cycle with notice requirements respected. Cross-tenure zones (lobbies, reception, lift cores) flagged for shared evidence. The managing agent sees every building from one screen, with each occupier seeing their own slice in their own portal.

Access-aware workflow

An engineer app that respects building security.

Engineers see the access protocol before they arrive: turnstile passes, reception sign-in, after-hours security escort, occupier liaison contact. They can defer if an occupier refuses access on the day, photograph the timestamped reason, and the managing agent routes the rebook with the right notice period. The audit trail evidences the landlord's reasonable steps under the FSO.

Occupier-readable transparency

A plaque every occupier and fit-out contractor can scan.

Every fire door across the building carries a QR plaque. Occupiers, fit-out contractors, the building manager, and the landlord's asset manager can verify a door's compliance from their own phone in seconds. Plaques survive office moves, fit-out churn, and twenty years of office traffic. The audit record per door supports dilapidations evidence at lease end.

Scenario

A week in the life of a managing agent property manager.

It is 09:00 on Monday morning. The Property Manager at a national managing agent, responsible for fifteen multi-let commercial office buildings on behalf of three institutional landlords, opens DoorTRACE alongside the week ahead in Outlook.

Mon 09:00

A Tier 1 occupier at 100 Cheapside is finalising their fit-out spec ahead of demising-wall installation on Friday. The Property Manager pulls the building's compartmentation plan and the fire door schedule from DoorTRACE, verifies the FD60S specification matches the strategy, and signs off the alterations consent with the audit reference attached.

Tue 11:30

Routine inspection at 25 Fenchurch Place. The engineer logs three fire doors on the twelfth floor with disabled closers, two wedged open with door wedges, one with the arm physically removed. Photos timestamped. Non-compliance notice raised against the occupier with the lease clause cited and a seven-day rectification deadline. Auto-copied to the building's fire risk assessor.

Wed 14:00

Quarterly asset management review with the REIT that owns five of the fifteen buildings. The Property Manager presents the portfolio compliance status, top defect categories, contractor performance, and the dilapidations exposure on three buildings approaching lease events. Pack includes the GRESB-aligned compliance summary the asset manager forwards to the sustainability committee.

Fri 16:00

Occupier B at 60 Threadneedle Court is exiting at end of lease in six weeks. The Property Manager runs the dilapidations export: five-year fire door compliance history for that demise, every fit-out alteration, every inspection, every defect rectified or outstanding. The schedule of dilapidations cites the export by audit reference, defensible at any future negotiation.

Frequently asked

Questions managing agents and asset managers ask us.

Buildings are modelled at the building level with demises tagged inside them. Each demise carries the lease metadata: lease type, responsibility allocation per element, and any specific clauses. Communal fire doors and the building cycle rest with the landlord; demised doors and internal cycles rest with the occupier where the lease requires. The audit trail shows who carried the duty and who produced the evidence, by element.
