Evacuation Route Planning Guide for UK Premises

A fire alarm can provide an early warning, but it cannot make decisions for the people leaving your building. When corridors become smoky, a usual exit is unavailable or visitors are unfamiliar with the site, clear evacuation routes and a practised plan are what turn that warning into a safe response.

This evacuation route planning guide is for employers, duty holders, facilities managers and landlords responsible for commercial premises in the UK. It explains how to establish escape arrangements that are realistic for your building, suitable for the people using it and capable of standing up to daily operational pressures.

Why evacuation routes need active planning

For most non-domestic premises in England and Wales, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to take general fire precautions. This includes ensuring that routes to emergency exits are kept clear and that people can safely evacuate in the event of danger. Equivalent fire safety legislation applies in Scotland and Northern Ireland.

A route shown on a drawing is not automatically a safe route in practice. Storage can appear in corridors, internal layouts can change, doors can be secured for security reasons, and contractors or temporary staff may not know where to go. In multi-occupancy buildings, changes made by one occupier can affect the safety of everyone else.

Your fire risk assessment should identify hazards, people at risk and the measures needed to manage them. Evacuation route planning translates those findings into practical arrangements: who leaves by which route, how they receive warning, where they assemble and how you confirm that nobody has been left behind.

Start with the people, building and daily use

Walk the premises as they are actually used, not simply as they were designed. Consider peak occupancy, shift changes, deliveries, public access and periods when parts of the building operate differently. A warehouse with forklift activity, for example, needs routes that remain protected from temporary stock and pallet movements. An office with controlled access needs emergency doors that can be opened immediately without compromising day-to-day security.

Identify everyone who may need to evacuate. This includes employees, visitors, contractors, lone workers, customers and people working in isolated areas such as plant rooms, loading bays or upper floors. Consider anyone who may need assistance because of mobility, sight, hearing, language or familiarity with the building.

The answer is not always a single evacuation method. A small, single-storey workplace may safely use simultaneous evacuation, where everybody leaves on hearing the alarm. Larger or more complex sites may need phased evacuation, staff sweep procedures or specific personal emergency evacuation plans, commonly known as PEEPs. The correct approach depends on the fire strategy, building design, occupancy and risk assessment.

Map primary and alternative escape routes

Each occupied area should have a clear route to a place of ultimate safety, normally outside the building and away from immediate danger. Where the risk assessment requires it, provide more than one direction of travel so that a fire or smoke on one route does not trap people.

Routes should be direct, suitably signed and adequately lit. They must lead to exits that can be opened easily from the inside without a key, code or specialist knowledge when the building is occupied. Security arrangements such as access control, maglocks and roller shutters need careful integration with the fire alarm and emergency release systems. A locked door that protects an asset during normal operation must not delay escape during an emergency.

Do not assume a route remains safe because it looks clear during a daytime inspection. Check it during a busy shift, after deliveries and when cleaning or maintenance work is under way. Pay particular attention to final exits, stairwells, external walkways and areas where waste, furniture or stock can accumulate.

Make emergency lighting and signage do their job

Escape route signs should direct people clearly towards exits and remain visible where a decision is required, such as a corridor junction or staircase. Signs must be consistent with the route people are expected to use. Conflicting signs, faded notices and outdated assembly point information create hesitation when time matters.

Emergency lighting is equally practical. If normal lighting fails during a fire, people still need to identify changes of level, fire alarm call points, firefighting equipment and exit doors. Testing and maintenance should be planned in line with the relevant British Standard and your system design. A monthly function test alone will not reveal every issue, so a competent annual duration test and accurate records are essential.

Build a plan that works under pressure

An evacuation plan should be concise enough to use and detailed enough to assign responsibilities. It should explain how the alarm is raised, how people are alerted, which routes are available, where they assemble and how emergency services are met and informed.

For many premises, the following controls need clear ownership:

• Keeping escape routes, stairwells and final exits unobstructed throughout the working day.

• Checking that fire doors close effectively and are never wedged open unless an approved hold-open device is in use.

• Supporting visitors and any person with a PEEP or temporary assistance requirement.

• Carrying out designated area checks only where this can be done without placing staff at risk.

• Accounting for people at the assembly point and communicating relevant information to the fire and rescue service.

Avoid assigning a sweep of every room as an automatic task if the building has a developing fire or heavy smoke. Staff should never be expected to search areas beyond the limits of their training, equipment and personal safety. In some sites, a roll call system, visitor record and reliable communication process offer a safer way to identify concerns after evacuation.

Assembly points should be far enough from the building to avoid smoke, falling debris and emergency vehicle access routes. They should also be appropriate for prevailing site risks. A point beside a fuel store, lorry manoeuvring area or the main fire appliance entrance is unlikely to be suitable. Consider a secondary assembly point where wind direction, site layout or an incident could make the primary location unsafe.

Test the evacuation route planning guide, not just the alarm

Fire drills reveal whether arrangements work in real conditions. They should test more than audibility of the fire alarm. Observe how quickly people recognise the signal, whether they choose the intended routes, where congestion occurs and whether wardens, reception staff and managers understand their roles.

Vary drill conditions where it is safe and proportionate. A drill carried out on a quiet Tuesday morning may not expose the problems that occur during a shift handover, a customer event or a delivery period. In a multi-tenant site, coordinate with other occupiers and the person responsible for common areas. An evacuation plan that works only for one business is not sufficient if routes and exits are shared.

Record the outcome of each drill and address issues promptly. Common actions include improving signage, moving storage locations, updating visitor procedures, repairing emergency lighting, retraining fire wardens or reviewing whether a PEEP remains suitable. Treat recurring problems as a management issue, not simply a staff behaviour issue. If an exit is continually obstructed, the layout or operational process may need to change.

Keep route planning aligned with fire systems

Your evacuation arrangements rely on several systems working together. The fire alarm system should provide suitable warning coverage and be tested routinely in accordance with its maintenance regime. Emergency lighting must illuminate the route if mains power fails. Automatic opening vents may support smoke clearance in relevant buildings, while fire doors and compartmentation help protect escape routes for longer.

Changes to one system can affect the whole strategy. For example, altering a partition wall may reduce alarm audibility, obscure a sign or change travel distances. Adding access control can introduce a delay at an exit. A refurbishment, new tenant, change of use or increase in occupancy should trigger a review of the fire risk assessment and evacuation plan.

A competent fire and security provider can help assess how fire alarms, emergency lighting, AOV and access control arrangements interact, particularly where a site has been altered over time. Connect Fire Security supports businesses with designed, installed and maintained life-safety systems, alongside practical compliance support that considers the way premises operate day to day.

Review after every meaningful change

Set a routine review schedule, but do not wait for an annual date if circumstances have changed. Review evacuation routes after building works, layout changes, new machinery, significant staffing changes, incidents, false alarms or fire drills that expose a weakness. Keep plans, training records, test results and maintenance documentation accessible for managers and, where required, enforcing authorities.

The strongest evacuation arrangements are rarely the most complicated. They are the ones people can understand immediately, follow without delay and rely on when normal conditions have disappeared. Give your routes the same attention as the fire alarm that starts the evacuation: both are essential to getting everyone out safely.
