No UK law says “test your emergency lighting every month”. What the law requires is that escape routes and exits which need lighting have emergency lighting of adequate intensity if the normal lighting fails, and that it is kept maintained in efficient working order. The monthly and annual intervals come from the British Standards for emergency lighting, as summarised in government fire safety guidance: a short functional “flick” test of every emergency light each month, recorded in a logbook, and a full-duration test with inspection by a competent person once a year. That routine is what inspectors normally expect to see.

This guide covers emergency escape lighting in workplaces and other non-domestic premises. Testing the fire alarm is a separate weekly routine, covered in our guide on how often fire alarms should be tested.
Is monthly emergency lighting testing a legal requirement?
Not in those words. In England and Wales, Article 14 of the Regulatory Reform (Fire Safety) Order 2005 deals with emergency routes and exits. Where necessary to keep people safe, paragraph (2)(g) says emergency routes and exits must be indicated by signs, and paragraph (2)(h) says routes and exits that need illumination must be provided with emergency lighting of adequate intensity in case the normal lighting fails. Article 17 then requires equipment provided under the Order to be “subject to a suitable system of maintenance” and kept in efficient working order and good repair.
Scotland and Northern Ireland use almost identical words. Regulation 13 of the Fire Safety (Scotland) Regulations 2006 and regulation 13 of the Fire Safety Regulations (Northern Ireland) 2010 contain the same emergency lighting wording, and regulation 16 of each sets out the maintenance duty (Scotland, Northern Ireland).
None of these provisions mentions a month or a year. The intervals come from the emergency lighting standards: BS 5266-1, the code of practice for emergency lighting of premises, and BS EN 50172, which covers emergency escape lighting systems including their testing. Both are paid documents, so the intervals in this article are taken from the government and fire sector guidance that summarises them, not from the standards themselves. Both have also been revised recently: BSI published BS EN 50172:2024 in July 2024 and BS 5266-1:2025 in October 2025, so it is worth asking your contractor whether your regime reflects the current editions.
In practice, the monthly and annual tests are how you show that a “suitable system of maintenance” exists. If you choose a different routine, you need a reason you can explain and records proving the lights still work.
How often should emergency lighting be tested and serviced?
Monthly by someone on site, and annually by a competent person. The Home Office guide to making small non-domestic premises safe from fire lists a monthly functional test of all emergency escape lighting units and an annual inspection and test by a competent contractor. The Home Office fire safety risk assessment guide for offices and shops and the Scottish Government’s practical fire safety guidance for existing non-residential premises add more detail. Together they set out this routine:
| When | What | Who | Source |
|---|---|---|---|
| Daily, where practicable | Visual check that emergency light fittings are in good repair and working, charge indicators (if fitted) are lit, and any central battery controls show normal | Trained member of staff | Home Office offices and shops guide |
| Monthly | Short functional test of every emergency luminaire and illuminated exit sign using the test switch, at a time when the lights will not be needed straight afterwards | Trained member of staff, or contractor | Home Office guides and Scottish guidance |
| Annually | Full discharge test for the system’s full rated duration (commonly three hours), plus inspection and maintenance | Competent person, usually an emergency lighting contractor | Home Office guides and Scottish guidance |
| After building changes | Review whether new partitions, room layouts or changes of use mean the lighting no longer covers the escape routes | Responsible person, with a competent person | Fire Safety Order duty to review the fire risk assessment |
Treat this as the minimum. The Home Office guide stresses that its examples are not prescriptive and that other regimes may be appropriate, and your fire risk assessment, the manufacturer’s instructions or your contractor may recommend more. The example checklist in the 2006 Home Office guide also includes a six-monthly test at one third of the rated duration, which reflects an older testing regime; the same guide’s main text and more recent fire sector guidance, such as the Fire Protection Association’s article on testing emergency lighting, describe the monthly and annual tests as the general minimum.
What is emergency lighting and which types need testing?
Emergency lighting is lighting that comes on automatically when the normal supply fails. Warwickshire County Council’s fire safety guidance explains the terms used in BS 5266. Emergency lighting divides into emergency escape lighting, which is the part the Fire Safety Order requires, and standby lighting, which lets normal work carry on during a power cut and is not a legal requirement. Escape lighting is itself split into three parts:
- Escape route lighting makes sure people can identify and safely use the escape routes.
- Open area lighting, sometimes called anti-panic lighting, gives enough light in larger spaces for people to reach a point where they can see an escape route.
- High-risk task area lighting lights areas where a dangerous process or machinery needs to be shut down safely before people leave.
Fittings are either maintained, meaning the emergency lamp is on all the time, or non-maintained, meaning it only comes on when the normal lighting fails. Non-maintained fittings are typical in offices and workplaces. Maintained fittings are used where the normal lighting can be dimmed while people are present, such as cinemas, theatres and nightclubs.
The power can come from a battery inside each fitting (a self-contained luminaire), from a central battery system that feeds many fittings, or from an automatic-start generator. Systems are designed to run for between one and three hours. The Home Office guide notes that three hours is the most popular, and the Warwickshire guidance explains that one hour is only suitable where premises are evacuated straight away and not reoccupied until the batteries have fully recharged.
Every type needs testing. The method varies between installations, but the principle is the same: prove each fitting lights when the mains fails, and once a year prove it stays lit for its full rated duration.
How do you carry out a monthly emergency lighting test?
The monthly test, often called a flick test, simulates a failure of the normal supply for long enough to confirm that every emergency lamp comes on. On many self-contained systems, test facilities take the form of a “fishtail” key inserted into a special switch, either near the main fuse board or next to the relevant light switches. The Fire Protection Association recommends using the key switch rather than switching off the mains lighting, which could leave other people in the dark. Always follow the manufacturer’s or installer’s instructions, but a typical test goes like this:
- Pick a sensible time. Government guidance says to test when the lighting will not be needed immediately afterwards. Before or after working hours, or a quiet daytime period, usually works.
- Tell people. Let colleagues know the emergency lights will be on test.
- Take the plan and the logbook. You need to know where every fitting is. Each light should have a location reference so results can be recorded against it.
- Operate the test switch. Insert the key and turn it to simulate a mains failure for that circuit or area. If there are several key switches, test each in turn.
- Walk the whole route. Check that every emergency luminaire and illuminated exit sign on that circuit has come on, including stairs, corridors, toilets, plant rooms and the outside of final exits.
- Look at the condition of each fitting. Diffusers should be clean, undamaged and unobstructed, and fittings should still be securely fixed.
- Keep the test short. The Home Office guide describes operating the test facility for a period sufficient to make sure each emergency lamp lights. Longer drains batteries for no benefit.
- Restore the supply. Turn the key back and remove it. Walk the route again to check that charge indicators, where fitted, have come back on.
- Record the result and report faults. Write down the date, the circuits tested, any failures and who did the test. Report faults to the responsible person straight away so a repair can be arranged.
Monthly emergency lighting test checklist
- Test time chosen so the lights will not be needed immediately afterwards
- Staff told the emergency lights are being tested
- Test key switch operated for every circuit or area
- Every emergency luminaire lit, checked against the plan
- Every illuminated exit sign lit
- Fittings clean, undamaged, secure and not blocked by stock, signs or decorations
- Mains supply restored and key removed
- Charge indicators (if fitted) lit again after the test
- Failed or damaged fittings reported to the responsible person
- Result recorded in the emergency lighting logbook
What is the annual full-duration emergency lighting test?
Once a year, the system is run for its full rated duration to prove the batteries can still keep the lights on for as long as they were designed to. For a three-hour system, that means three hours. The Fire Protection Association describes switching off the normal lighting supply and leaving the emergency lights on for the full period, with every luminaire required to stay lit throughout. Any fitting that dims or goes out early has failed, even if it passed every monthly test.
That is the reason both tests exist. A monthly flick test proves the lamp, the changeover and some battery charge are working. It cannot show that the battery will last long enough to get everyone out. Only the full-duration test does that.
Timing matters more for this test than for any other. After a full discharge, the batteries are flat. The Home Office offices and shops guide says batteries typically take 24 hours to recharge, and that the premises should not be reoccupied until the emergency lighting is fully working again, unless alternative arrangements have been made. In practice, that usually means testing when the building will be empty for at least the following day, such as the end of a working week, or making other arrangements, such as splitting the test so that only some circuits are discharged at a time if your system allows it. Your contractor can advise which approach suits your building.
The annual test is usually combined with inspection and maintenance by a competent person. The FPA notes that it is sometimes carried out during a fire alarm service visit, because the engineer can work on the alarm while the lights run down. You should get a written record or certificate for each annual test and keep it with your logbook.
Who can test emergency lighting?
The monthly test can be done by a trained person on site, such as a facilities manager, caretaker, office manager or fire warden. The Home Office guide says that, depending on the type of installation, you should be able to carry out most routine tests yourself, and that if you are not sure how, you should contact your supplier or another competent person. No formal qualification is needed, but they must know where every fitting is, how the test switches work and how to report a fault.
The annual full-duration test, inspection and any repairs should be done by a competent person. In practice, that usually means an electrical or fire safety contractor with emergency lighting experience. The government guidance also says that installing or modifying an emergency lighting system should be done by a competent person in line with the appropriate standards.
Responsibility stays with the responsible person under the Fire Safety Order, usually the employer or whoever controls the premises. Fire safety training for the people involved is a separate legal duty, explained in our guide to fire safety training and UK law.
Do self-testing emergency lights still need checking?
Yes, but less often by hand. The Home Office guide notes that some modern systems have self-testing facilities that reduce routine checks to a minimum, and the Scottish guidance says the same. These systems run the tests automatically and report the result, for example through an indicator on each fitting or a central panel. BSI says the 2024 edition of BS EN 50172 added new requirements for automatic test systems.
Self-testing does not mean nobody looks. Someone still needs to check the indicators or panel regularly, record what they show and act on any failure reported. A self-test that has been flagging a failed battery for six months is no better than no test at all. Annual inspection and maintenance by a competent person are still needed.
What should an emergency lighting logbook include?
The Home Office guide says it is good practice to keep a record of tests, and the Warwickshire guidance explains that the emergency lighting standards expect a log of all system tests and results. A good logbook, paper or electronic, includes:
- A plan or list of every emergency luminaire and exit sign, each with a location reference
- The commissioning or completion certificate from the installer
- The date, time and type of each test (monthly functional, annual full duration)
- Which circuits or fittings were tested and the result for each
- Any faults found, when they were reported and when they were put right
- The name of the person who carried out each test
- Certificates or reports from annual servicing visits
- Any alterations to the system, such as new fittings after a refit
Neither the Fire Safety Order nor the Home Office guide sets a retention period. The Scottish Government guidance suggests keeping maintenance and testing records for at least three years for possible audit by the enforcing authority, which is a sensible minimum anywhere in the UK.
What are the most common emergency lighting faults?
Most faults are simple and are found by routine tests done properly. Watch for:
- Batteries that do not last. A fitting lights on the monthly test but goes out well before its rated duration. Only the annual full-duration test finds this, which is why it should never be skipped.
- Charge indicators that are out. On fittings with an indicator, an unlit indicator during normal operation suggests a supply, charging or battery problem.
- Damaged or dirty fittings. Cracked diffusers, fittings knocked loose or covers coated in dust reduce the light reaching the floor.
- Fittings that are blocked or hidden. Stock, signs, displays, plants or Christmas decorations can cover a fitting that worked perfectly on the day it was installed.
- Coverage lost after a refit. New partitions, a new office layout or a change of use can leave a corridor or room without the emergency lighting it needs. That is a reason to review the fire risk assessment, which the Fire Safety Order requires when there has been a significant change.
- Missing test keys and unlabelled switches. If nobody knows where the key is or which switch tests which circuit, the test does not happen.
Emergency lighting is only one part of your escape provision. Fire doors that keep smoke out of the route are just as important, as explained in our guide to fire door regulations.
Do small premises need emergency lighting?
Not always. The duty applies only to escape routes and exits that need illumination. The Home Office small premises guide says that if you need artificial lighting to see your way out, you must have emergency escape lighting. However, in most small ground floor premises with adequate borrowed light, such as street lighting that is expected to be available at all material times, there will generally be no requirement for it.
Where emergency lighting is needed, the same guide says it should clearly light exit doors and exit routes, including staircases, corridors and areas without natural light, such as basements. The offices and shops guide adds that, where borrowed light is not available in small premises, suitably placed torches may be acceptable for trained staff. If you rely on torches, they need checking too: the guide includes checking torch batteries and charge in its routine.
Your fire risk assessment is where this decision is made and recorded. Larger, more complex premises are likely to need a full automatic system.
Houses in multiple occupation are covered by local council standards as well as fire safety law. For example, Oxford City Council recommends a short monthly test and a full annual test, and requires licensed HMO landlords to send a yearly self-declaration or certificate. Check your own council’s standards.
Which courses help with emergency lighting responsibilities?
These three £9 courses work well together for staff, fire wardens and the people who look after the building, each with a verifiable certificate:
- Fire Safety Awareness — the main fire safety legislation, how fire starts and spreads, detection and means of escape, preventing fire and responding safely, including the five-step fire risk assessment and emergency procedures.
- Fire Warden Fire Marshal — the same fire safety foundations, plus the day-to-day and emergency duties of a fire warden or fire marshal.
- Fire Safety in Offices — the Fire Safety Order in an office setting, including fire doors, detection and alarms, escape routes, signage and emergency lighting, extinguishers, PEEPs, fire wardens and drills.
Any three courses cost £18 with the pay-for-2-get-3 offer. Add them to the cart and the discount applies automatically. These are awareness courses: CPD accredited, but not regulated qualifications. They do not make anyone a competent emergency lighting engineer or fire risk assessor, and they do not replace testing and servicing by a competent contractor.

Frequently asked questions
Is monthly emergency lighting testing a legal requirement?
No law states a monthly test. The Fire Safety Order requires emergency lighting where escape routes need it and requires it to be kept in efficient working order under a suitable system of maintenance. The monthly test comes from the emergency lighting standards and government guidance, and it is the routine inspectors normally expect to see recorded.
How long should an annual emergency lighting test last?
For the system’s full rated duration, which is commonly three hours. Systems are designed to last between one and three hours, so check the rating on your fittings or ask your contractor. Every luminaire should stay lit for the whole period.
How long do emergency light batteries take to recharge after a test?
Home Office guidance says batteries typically take 24 hours to recharge after a full discharge test. The premises should not be reoccupied until the emergency lighting is fully working again, unless alternative arrangements have been made.
Who is allowed to do the monthly emergency lighting test?
Any trained person on site, such as a facilities manager, caretaker or fire warden. No formal qualification is needed for the monthly flick test, but the annual full-duration test, inspection and repairs should be done by a competent person.
Do self-testing emergency lights need a monthly check?
They need less hands-on testing, but someone must still check the indicators or panel regularly, record the results and act on any failure. Annual inspection and maintenance by a competent person are still needed.
How long should you keep emergency lighting test records?
There is no fixed period in the Fire Safety Order. Scottish Government guidance suggests keeping maintenance and testing records for at least three years for possible audit, which is a sensible minimum anywhere in the UK.
This article is general information about emergency lighting testing in UK workplaces and is not legal advice. Follow the manufacturer’s instructions, your contractor’s advice and your fire risk assessment. The law differs in Scotland and Northern Ireland, and local fire and rescue services and councils set their own policies. Nexis CPD courses are CPD-accredited awareness training, not regulated qualifications, and do not make anyone a competent emergency lighting engineer or fire risk assessor. If there is a fire, raise the alarm, get out and call 999.
