Lighting technicians are the unsung heroes behind every performance, event, or production. From theatre and concerts to corporate events and live broadcasts, your work transforms spaces and creates mood, drama, and focus. But all of this depends on electrical equipment—lighting rigs, dimmers, LED panels, moving lights, and cabling.
PAT testing (Portable Appliance Testing) ensures that your electrical gear is safe, reliable, and ready to perform, protecting both you and your audience while keeping the show running smoothly.
What Is PAT Testing?
PAT testing is the process of checking electrical appliances to ensure they are safe to use. It typically involves:
- Visual inspection – looking for damaged plugs, frayed cables, or signs of overheating.
- Electrical testing – using specialist equipment to detect hidden faults that could cause shock or fire.
Once tested, items receive a pass/fail label, and a certificate is issued. For lighting technicians, this documentation helps demonstrate professionalism and compliance with safety standards.
Why PAT Testing Matters for Lighting Technicians
Even minor faults in lighting equipment can cause major disruptions or hazards. PAT testing helps by:
- Protecting technicians, performers, and the audience – preventing electric shocks or fires.
- Ensuring uninterrupted shows – avoiding equipment failure during critical moments.
- Meeting venue and industry standards – many theatres, studios, and event spaces require PAT certificates.
- Maintaining professional credibility – shows that you take safety and reliability seriously.
- Supporting insurance compliance – many liability policies for events require proof of PAT-tested equipment.
What Equipment Should Be PAT Tested?
Any portable electrical item used in lighting setups should be included:
- Stage lights, spotlights, and LED panels
- Moving lights, scanners, and intelligent fixtures
- Dimmer packs and control boards
- Extension leads, power strips, and cabling
- Portable fans, heaters, or ancillary appliances used backstage
Even small appliances in lighting booths or workshops should be included in PAT testing schedules.
How Often Should PAT Testing Be Done?
Frequency depends on use and mobility:
- Annually – for equipment regularly moved or used in multiple venues.
- Every 2 years – for stationary or infrequently used gear.
- After visible damage or repairs – always retest before use.
Many lighting technicians align PAT testing with seasonal production schedules to ensure all equipment is safe before every show.
Is PAT Testing a Legal Requirement?
PAT testing itself is not legally mandated, but UK and European regulations require that all electrical equipment used at work or in public spaces be safe. PAT testing is the recognised method to demonstrate compliance, and most venues will request certificates before allowing equipment setup.
Final Thoughts
Lighting technicians create the magic behind every performance, and safety is key to keeping that magic uninterrupted. PAT testing ensures your equipment is safe, reliable, and professional, allowing you to focus on creating spectacular lighting effects without worrying about electrical hazards.
Because the only sparks at your show should be from the lights—not faulty equipment.
