Emergency Lighting Maintenance in the UK: What You Need to Know
Keep Your Emergency Lights Working: A British Standard Maintenance Guide
What's the British Standard for Emergency Lighting Maintenance?
Emergency lighting is there to guide people to safety when the power goes down or disaster strikes. If you're running a building in Telford or Shropshire or anywhere in the UK, it's vital to know what the British Standard expects of you when it comes to maintaining these systems. This article walks through the key standards, explains why maintenance matters, and gives you practical steps to keep everything in working order.
Why should you bother with emergency lighting maintenance?
Let's be honest: emergency lighting isn't a nice-to-have. It's a safety-critical system that could save lives. The British Standard sets out the bare minimum you need to do—design, installation, testing, maintenance, the lot. When you maintain it properly, you stop things from going wrong when people need them most, you reduce the risk to anyone in your building, and you stay on the right side of the law. In other words, keeping your emergency lighting well-maintained can genuinely save lives.
Which standards and regulations apply?
Several key documents shape emergency lighting maintenance in the UK:
BS 5266: Emergency lighting
- Part 1: Code of practice for emergency escape lighting in buildings
- Part 7: Code of practice for designing, installing, operating and maintaining performance test systems
BS EN 50172: Guidance on maintaining emergency lighting systems
The Regulatory Reform (Fire Safety) Order 2005 (as amended): This applies to non-domestic buildings and places a legal duty on the responsible person to ensure safety measures—including emergency lighting—are in place and properly looked after.

Approved Document B (Fire Safety): This may also inform how emergency lighting should work in different types of building.
Worth noting: BS 5266 is the main standard used across the UK, though many organisations use BS EN 50172 alongside it, especially when they're aligning with European standards or following product guidance.
What does BS 5266 actually require for maintenance?
BS 5266 gives you comprehensive guidance on keeping emergency lighting in good shape. Here's what it covers:
Routine testing: Regular checks to make sure fittings are clean, batteries are charged, and the lights come on when they should.
Functional testing: Periodic tests that mimic a power failure so you can verify the emergency lights actually work and stay on for as long as they're supposed to (usually around 3 hours, depending on your system and space).
Longer-term testing: Annual checks (or less frequently, depending on your setup) to assess battery condition, lamp performance, and the overall health of the system.
Keeping records: You need to document everything—tests, results, what you've done about problems, any faults you've spotted. All of it.
How does BS EN 50172 fit in?
BS EN 50172 works alongside BS 5266 by offering guidance that aligns with European standards. It helps you understand:
- How often you should inspect things
- The right way to test
- What counts as acceptable performance
- How to make sense of test results
- What a sensible maintenance schedule looks like
Building a maintenance plan that actually works
To set up a maintenance regime that does the job, you need a clear schedule and documented procedures. Here's what good practice usually looks like:
Visual inspections: Check things monthly or quarterly. Make sure the lights are clean, nothing's blocking them, and there's no damage.
Functional tests: Run these monthly if you can. Switch off the mains power and check that all the emergency lights come on. In bigger or more complex buildings, you might do this in stages to avoid causing disruption, and you'll record everything.
Duration tests: Do these annually. Run the system on emergency power for the full rated time (typically 3 hours) to confirm the batteries will last and the light output is still good.
Battery testing: Check battery health regularly and swap them out according to what the manufacturer recommends and what BS 5266 says.
Reporting and fixing faults: You need a clear process for logging problems, working out how serious they are, and getting them repaired promptly.
Documentation: keep proper records
This is a core requirement, and you can't skip it. Your records should include:
- Inspection checklists with dates and the names of whoever did the work
- Functional test results—which lights passed, which ones didn't
- Duration test results and anything unusual you noticed
- Battery health checks and when you replaced them
- Any fixes you've made and who was responsible
- Certificates or reports you can show during an audit or inspection
Making sure your team knows what they're doing
Anyone maintaining your emergency lighting needs to be properly trained and understand the standards. Training should cover:
- What BS 5266 and BS EN 50172 actually require
- Safe working practices when dealing with electrical systems
- How to use testing equipment properly and understand what the results mean
- How to report problems and get them sorted
- Common mistakes and how not to make them
Watch out for these common mistakes
Testing too infrequently: Faults can hide if you're not checking regularly enough. Stick to your testing schedule and keep detailed records.
Poor record-keeping: Sloppy documentation won't help you at audit time. Keep everything in a system that's easy to access and update.
Using the wrong components: Make sure any parts you use meet the requirements of BS 5266 or BS EN 50172.
Ignoring battery condition: Batteries don't last forever. Monitor them regularly and replace them when the manufacturer and the standards say you should.
Not adjusting for your building: The testing frequency should match the risks in your building, how many people use it, and what the regulations expect. One size doesn't fit all.

Wrapping up
Emergency lighting maintenance is an ongoing responsibility for building owners, facilities managers, and anyone legally responsible for fire safety. If you make BS 5266 your foundation and align with BS EN 50172, you can build a maintenance system that keeps emergency lighting reliable when it counts. Regular testing, proper record-keeping, and continuous training are the fundamentals. Getting this right isn't just about staying legal—it also gives the people in your building confidence that they're safe, and that matters.
