How Often Should Emergency Lighting Be Tested in the UK?
Your Guide to UK Emergency Lighting Compliance
Emergency lighting is a critical safety requirement in most UK commercial and public buildings. It provides illumination during a power failure, helping people evacuate safely. Without it, a darkened building during an emergency can put lives at risk.
Is Emergency Lighting Testing a Legal Requirement?
Yes. Under the Regulatory Reform (Fire Safety) Order 2005, building owners and employers have a legal duty to maintain emergency lighting in good working order. The British Standard BS 5266-1 sets out the testing requirements that responsible persons must follow.
How Often Should Emergency Lighting Be Tested?
According to BS 5266-1, there are three levels of testing required:
Annual Short Test – Once a year, a one-hour test checks that the emergency lights operate for at least one hour. Results must be recorded and any failed units replaced promptly.
✅ Monthly Flick Test – Brief activation check, every month
✅ Three-Hour Discharge Test – Full 3-hour discharge test, carried out once per year
✅ All results must be recorded in a log book for compliance

Who Is Responsible for Emergency Lighting Testing?
What Happens If You Don’t Test Emergency Lighting?
The responsible person under fire safety law is accountable for ensuring emergency lighting is tested and maintained. This is typically:
• Business owners – for offices, shops, warehouses and commercial premises
• Landlords – for rented properties, HMOs and communal areas
• Facilities managers – for schools, care homes, public buildings
If you are unsure whether your building needs emergency lighting testing, the safest option is to check with a qualified engineer.
Failing to carry out regular emergency lighting testing puts people at risk and can have serious consequences for your business:
• Safety risk – If emergency lights fail during a fire or power cut, people may not be able to evacuate safely
• Insurance issues – Untested lighting can invalidate your insurance policy in the event of an incident
• Legal liability – You could face enforcement action, fines or prosecution under fire safety law
• Failed audits – Fire risk assessors expect to see a current log book with up-to-date test records
Regular testing is simple, affordable, and keeps you covered.
