Emergency Lighting for Schools: BS 5266-1 Duties, Testing and Exit Signage Explained

Schools must provide emergency lighting that allows safe evacuation when normal lighting fails, designed to BS 5266-1 and tested under the regime set out in BS EN 50172. In practice that means emergency luminaires along every escape route and in open teaching areas, illuminated exit signage, brief monthly function tests, an annual full-duration test and a log book recording all of it. This guide sets out who is responsible, where the luminaires go and how a summer refurbishment is the cheapest moment to close the gaps.

Who is legally responsible for emergency lighting in a school?

Fire safety law places duties on the responsible person: depending on structure, the headteacher, the trust's estates lead, the governing body or the local authority. The responsible person must ensure the premises have adequate emergency lighting, that it is maintained in working order, and that testing is carried out and recorded. The duty cannot be delegated away by hiring a contractor; the contractor does the work, the responsible person owns the outcome.

Two standards carry the technical weight. BS 5266-1 is the code of practice for emergency lighting design: where luminaires are needed, what light levels escape routes require and how long the system must run. BS EN 50172 specifies the testing and record-keeping regime. A fire risk assessment that finds inadequate emergency lighting creates an action the school must close, and inspectors, insurers and HSE guidance on workplace duties all point back to the same evidence: the design, the test records and the log book.

Where does a school need emergency luminaires?

BS 5266-1 works outward from the escape route. The standard positions cover:

• Escape routes: corridors, stairs and final exits, lit to defined minimum levels along the centre line, with extra attention at changes of direction and level.
• Exit doors and the signage above them, so the way out is identifiable in darkness and smoke.
• Open areas above a threshold size, including halls, dining rooms, libraries and large open-plan teaching spaces, so occupants can reach an escape route from anywhere in the room.
• High-risk task areas, such as science prep rooms and DT workshops, where a sudden blackout mid-task is itself dangerous.
• Points of emphasis: firefighting equipment, fire alarm call points, first aid points and plant rooms.
• Toilets above a minimum size and accessible toilets, which evacuation plans routinely forget.

Duration is normally three hours for premises like schools, which supports both evacuation and the decision to re-occupy or send pupils home in a prolonged outage.

What products do the job?

Emergency provision comes in two forms, and most schools use both. Emergency conversion packs turn a standard luminaire into an emergency one: the LOKI PRO+ 600×600 classroom panel offers an emergency pack option, so the panel lighting the room also covers the open-area requirement with no extra ceiling penetrations. Dedicated emergency luminaires then handle the specific tasks: the CLIO ultra slim exit sign marks final exits and direction changes, the SOTERIA 4-in-1 emergency exit unit covers multiple mounting and legend configurations from one product, and AMMA emergency spots provide discreet escape route and open-area coverage where a full panel is unnecessary. The complete range is in the emergency lighting category.

Exit signage deserves its own line in the schedule. Signs must use the standard running-man pictogram, be visible at the required viewing distance, and form a continuous chain: from any point in the building, the next sign should always be visible. A signage walk-through during design, following each escape route as an unfamiliar visitor would, catches the gaps a desk exercise misses.

What testing does BS EN 50172 require?

Monthly: a brief function test of every emergency luminaire and exit sign. Simulate a mains failure (usually via key switches on the lighting circuits), confirm every unit illuminates, restore power, record the result and any failures.

Annually: a full rated duration test, normally three hours. Every luminaire must still be lit at the end of the period. Batteries near end of life pass the monthly flick test and fail the annual one, which is exactly why both exist.

Always: record everything in the emergency lighting log book: test dates, results, failures and remedial actions. The log book is the first document a fire officer or insurer asks for, and an empty one is treated as evidence the testing never happened.

Plan the annual test for a holiday or weekend, because the batteries then need up to 24 hours to recharge, during which protection is reduced. The summer break is the natural slot, alongside any installation work.

Why is a refurbishment the right moment to fix emergency lighting?

Because the marginal cost collapses. The access equipment is on site, the ceilings are open, the electrician is already wiring every room and the school is empty. Adding emergency packs to panels being installed anyway, and scheduling CLIO or SOTERIA units along the escape routes, costs a fraction of a standalone emergency project a year later. It also produces one coherent system with one commissioning record, rather than layers of additions from different decades.

The design step matters as much as the hardware. The free lighting design service from Signature LED Lighting's in-house engineers schedules emergency provision room by room alongside the general lighting: which panels carry emergency packs, where the exit signs sit, and the duration and category for each space. The output gives the contractor a priceable schedule and gives the school the design documentation BS 5266-1 expects. Like every general luminaire, emergency products come with a 5-year warranty, two years of it on site, with terms set out on the onsite warranties page.
