6 Logbook Fields to Pass a Monthly Emergency Lighting Test in the UK

Published 29 September 2026 · gribit

Emergency lighting test title card

You must carry out a monthly functional (flick) test of emergency lighting in most UK premises and record the result. The test confirms each luminaire switches to battery power correctly, and both BS 5266-1 and the Fire Safety Order require you to keep evidence of it. A digital logbook, such as Gribit, is one practical way to store that evidence.

TL;DR:

Accurate and complete documentation of each test, including faults and remedial actions, is essential for legal compliance and inspector scrutiny.

Monthly tests should be conducted by trained staff using a test key, with immediate logging of results and faults, especially on escape routes or final exits.

A full-duration annual test verifies the system’s ability to sustain evacuation for the rated period, often around three hours, and should be logged alongside monthly checks.

Digital logbooks offer advantages like automatic timestamps, photo attachments, and reminders, making record retrieval and evidence presentation faster and more reliable.

Repairs to faults affecting escape routes must be prioritized, with interim safety measures implemented until permanent fixes are completed, and all actions properly documented.

1. Step-by-step monthly flick test procedure

Set aside a short window when the building is quiet and lighting will not be missed if a fault appears. Gather your test key (often called a fish key), any PPE the site requires, and something to note results on as you go. Tell staff beforehand if the test will affect areas they are working in.

Use the test key to isolate the local lighting circuit rather than switching off the mains supply.
Check each luminaire and exit sign in turn, confirming it illuminates from its battery.
Note any fitting that fails to light, flickers, or shows a weak output.
Restore the mains supply promptly once the circuit has been tested.
Watch for the charge indicator returning to normal, confirming the battery is recharging.
Write down every result immediately, including passes, so the log is complete.

Pro Tip: Test in short bursts rather than isolating the whole system at once. Leaving fittings off circuit for longer than necessary delays recharging and can leave the system under-prepared if there is a real emergency straight after.

A common mistake is forgetting to withdraw the test key afterwards, which can leave a fitting isolated without anyone noticing. Another is rushing the restart and not waiting to see the indicator light change before moving on.

2. What to record: minimum logbook fields and best practice

Whether you use a paper logbook or a digital one, each monthly entry needs enough detail to satisfy an inspector months later. At minimum, record:

Date and time of the test.
Location or fitting identifier for each luminaire checked.
Tester’s name and signature.
Result for each fitting, including passes.
Description of any fault found.
Remedial action taken or planned, with an owner and a target completion date.

Keeping these records accessible matters as much as creating them. An inspector or auditor will ask to see the history of tests, not just the most recent one, so a logbook that is easy to retrieve and hard to lose is worth more than a more detailed one buried in a filing cabinet. Digital logbooks help here because entries carry automatic timestamps and can attach photos, which is useful when you replace a lamp or battery and want a record of the part fitted.

3. Legal duties and standards in the UK: a concise compliance summary

Under the Regulatory Reform (Fire Safety) Order, the responsible person must maintain fire safety measures, including emergency lighting, and keep evidence that testing and servicing have taken place. Delegating the task to staff does not remove that duty; the responsible person remains accountable if records are missing or the system has been neglected.

BS 5266-1 sets out the testing schedule most UK premises follow: a monthly functional check and an annual full-duration test, with results logged each time. BS EN 50172 covers the wider emergency lighting system requirements that sit alongside it.

UK emergency lighting compliance schedule

Your fire risk assessment should confirm whether the standard monthly and annual schedule is enough for your premises, or whether higher-risk activities mean testing more often. Inspectors are entitled to ask for your records at any time, so treat the logbook as part of your defence, not paperwork for its own sake.

4. Who should do the monthly tests and what competence is required

Monthly checks can be carried out by any instructed, competent member of staff. They do not need to be an electrician, but they do need proper instruction on how the test facility works, what a pass and fail look like, and what to do if a fitting does not respond.

BAFE and BS 5266-1 guidance recommend that whoever commissions the system trains the responsible person, or their nominated staff, on the test key and indicator lights at handover. Keep a record of that training. Repairs and the annual full-duration test are better left to a qualified electrician, particularly on central battery systems.

5. Common faults, interim safety measures and repair prioritisation

Monthly tests tend to turn up the same handful of problems: a failed lamp, a battery that will not hold charge, physical damage to a fitting, or an indicator light showing the wrong state. None of these should wait until the next scheduled test.

Record the fault immediately, with its location and a description.
If the fault affects an escape route or final exit, consider restricting access or providing temporary signage or lighting until it is fixed.
Prioritise repairs on escape routes and final exits over less critical areas.
Log the contractor used, parts replaced, and the date of the retest.

Interim measures matter because a fault on an exit route is a safety gap, not just an administrative one, until it is closed.

6. Annual full-duration test: overview and how it complements monthly checks

Once a year, BS 5266-1 calls for a full-duration discharge test, typically running the system on battery for the full rated period, often around three hours, to confirm it can sustain an evacuation rather than just switch on briefly. This is usually carried out by a technician and can be phased across the building to avoid leaving large areas without cover at once. Any faults found feed straight into your repair log alongside the monthly entries.

7. Practical benefits of a digital logbook for monthly tests

A digital logbook timestamps each test automatically, lets you attach a photo of a faulty fitting, and can remind you before the next test falls due, which cuts down on missed checks. When an inspector asks for evidence, exporting a complete history takes minutes rather than a search through old paperwork. This is one example of a digital logbook tool, often built around a per-site annual subscription.

Priorities and small wins for busy managers

Name the tester on every entry, keep the checklist short enough to actually finish, and treat every fault as a safety issue rather than a line item. A short training session and a simple digital logbook do more for your compliance position than any amount of extra paperwork.

How a site logbook can simplify monthly tests

Paper logbooks work until one goes missing or a page gets damp in a cupboard, which is usually when an inspector asks for it. A digital site logbook keeps timestamped entries, photo attachments and reminders in one place, and can export a clean report when you need to show evidence quickly.

Gribit

Gribit’s site logbook is built for exactly this: recurring checks like monthly emergency lighting tests, first-aid inspections and fire alarm tests, all logged against the site rather than scattered across notebooks.

FAQ

How often should emergency lighting be tested in the UK?

Emergency lighting needs a monthly functional test and an annual full-duration test under BS 5266-1. Some premises test more often if their fire risk assessment identifies higher risk activities or recurring faults.

What are the British standards for emergency lighting testing?

The main reference is BS 5266-1, which sets the monthly and annual testing schedule, alongside BS EN 50172 covering the wider system requirements. Both sit under the duties set out in the Fire Safety Order.

How do you carry out a monthly emergency lighting test?

You isolate the lighting circuit with a test key, confirm each luminaire and exit sign lights up on battery power, then restore the mains supply and check the charge indicator returns to normal. Every result, including passes, should be logged with the date, tester and any faults found.

How often are emergency lights required to be tested by law?

The Fire Safety Order requires the responsible person to maintain and evidence testing, and the accepted schedule under BS 5266-1 is monthly functional checks plus an annual full-duration test. Self-testing systems can automate the functional check but do not remove the requirement to keep records of it.
