Illustrative office fit-out scenario

Worked example: office FRA following a fit-out

See how a competent assessment might be scoped, what evidence could be needed and how possible findings could become a prioritised action plan.

PremisesApproximately 350 m² single-floor office
Illustrative areaWest London
TriggerNew partitions, meeting rooms and increased occupancy
Indicative FRA price£300–£650
Illustrative timescaleInspection near practical completion; report commonly within 3–7 working days

The premises, events, findings, cost range, timescale and outcome below are constructed examples. They show a possible assessment journey; they do not predict what an assessor would find at your building.

Example summary

What this scenario demonstrates

  • A completed fit-out can invalidate layout, travel and occupancy assumptions in the previous FRA
  • Building-control completion and an operational FRA answer different questions
  • New rooms can change detector coverage, alarm audibility and sprinkler distribution
  • The revised report should distinguish tenant, contractor and landlord actions

The fictional scenario

Premises and assessment trigger

Imagine an open-plan office being divided into meeting rooms, phone booths and a larger staff area. Occupancy increases, access control changes and new data cabling passes through parts of the ceiling. The tenant has fit-out drawings and a completion pack, but the existing FRA describes the old layout.

The assessment should compare the completed premises with the fire strategy, approvals and commissioning evidence. It should examine how the office will actually operate—not only whether the drawings show compliant intent.

Illustrative scope

What the assessment might need to cover

The final scope would depend on the real building, occupants, evidence and agreed limitations.

01

Changed layout

Travel distances, alternative routes, dead ends, exit visibility, door swings and credible occupancy.

02

Systems and interfaces

Detection, warning, emergency lighting, sprinklers, access control and landlord connections.

03

Construction

New walls, ceilings, doors, glazing and service penetrations affecting fire-resisting construction.

04

Operational readiness

Emergency plan, staff information, PEEPs, wardens, records and arrangements for defects.

Possible complications

What could make the assignment less straightforward?

01

Design and installation differ

Drawings may not record substitutions, late changes or every penetration made on site.

02

Commissioning is incomplete

Alarm, lighting or access-control records may still be awaiting issue or defect closure.

03

The office is eager to occupy

Commercial pressure can cause temporary arrangements to become permanent without formal acceptance.

Evidence to prepare

Records that would make this example more assessable

No single document proves that the premises is safe. Relevant evidence helps the assessor test construction, systems and management rather than rely on assumptions.

  • Previous FRA and action plan
  • Fit-out and reflected-ceiling plans
  • Fire strategy and landlord fit-out rules
  • Building-control and approval information
  • Alarm, lighting, sprinkler and access-control commissioning
  • Fire-stopping and fire-door evidence where relevant

Possible findings—not client findings

How observations could become useful actions

These examples are deliberately conditional. The actual significance, priority and solution would require inspection and professional judgement.

Example priorityPossible findingWhy it could matterIllustrative action
HighA new enclosed room is not adequately covered by the intended warning arrangement.People may receive delayed or ineffective warning inside the room.Obtain competent system review, complete required work and record testing before relying on the room.
HighAn access-controlled door does not release reliably under the emergency arrangement.A required escape route may not be immediately usable.Control use of the affected route and arrange competent interface testing and correction.
MediumCable penetrations above the ceiling lack reliable fire-stopping evidence.Unprotected openings may undermine intended compartmentation.Arrange a competent inspection, identify the required system and retain installation evidence.
PlannedOccupancy and warden assumptions still reflect the previous layout.The emergency plan may not work for the actual rooms, hybrid attendance and people needing assistance.Revise the emergency plan, assistance arrangements, staff information and drill programme.

Illustrative outcome

What a well-managed result could look like

A suitable illustrative outcome would be a revised premises record, closed commissioning defects, an action plan allocated across tenant and landlord responsibilities, and emergency arrangements reflecting the occupied layout.

The completed assessment should record limitations and any specialist work still required rather than treating practical completion as proof that every operational fire-safety issue has been resolved.

Transferable lessons

What a responsible person can take from the example

01

Assess what was built

Use drawings and certificates, but compare them with the completed rooms and systems.

02

Time the visit carefully

Too early and systems may be incomplete; too late and people may occupy before significant issues are controlled.

03

Test interfaces

Alarm, access control, sprinklers, smoke control and landlord systems can be affected by a tenant fit-out.

04

Update management

New rooms and occupancy require revised instructions, assistance and drill arrangements.

Frequently asked questions

Office FRA after fit-out questions

Does building-control approval replace the office FRA?

No. Building-control processes and the operational fire risk assessment have different purposes. The FRA must reflect the occupied workplace, people, activities and management.

When should the post-fit-out FRA be completed?

It should be planned around completion and occupation so the assessor can examine the actual layout and evidence while significant issues are controlled before people rely on the premises.

Who should provide the fit-out records?

Relevant information may come from the tenant, landlord, principal designer, contractors, system specialists and building-control process. The responsible persons should retain what they need to operate safely.
