Production designers are the creative visionaries behind the look and feel of films, TV shows, theatre productions, and commercials. From set construction and lighting rigs to props, monitors, and electronic devices, your work relies heavily on electrical equipment to bring ideas to life.
PAT testing (Portable Appliance Testing) ensures that all your gear is safe, reliable, and ready for use, protecting both your team and the production while maintaining a professional workflow.
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 – checking for frayed wires, damaged plugs, or signs of wear.
- Electrical testing – using specialist tools to detect hidden faults that could cause shocks or fires.
After testing, each item is labelled pass/fail, and a certificate is issued. This documentation demonstrates compliance with safety standards and helps maintain a professional production environment.
Why PAT Testing Matters for Production Designers
Electrical faults on a set can be dangerous and disruptive. PAT testing helps by:
- Protecting cast, crew, and audience – reducing the risk of electric shocks or fire hazards.
- Ensuring smooth production – preventing equipment failure that could halt filming or rehearsals.
- Meeting venue and industry standards – many studios and theatres require PAT certification.
- Maintaining professional credibility – showing that safety is a priority alongside creativity.
- Supporting insurance compliance – many production insurance policies require PAT-tested equipment.
What Equipment Should Production Designers Get PAT Tested?
Any portable or plug-in electrical device used on set or in the studio should be included:
- Lighting rigs, LED panels, and spotlights
- Monitors, cameras, and audio equipment
- Projectors, screens, and AV equipment
- Power tools used for set construction
- Extension leads, power strips, and adapters
- Small appliances used on set or in dressing rooms
Even equipment used infrequently should be tested to prevent unexpected hazards.
How Often Should PAT Testing Be Done?
Frequency depends on usage and mobility:
- Annually – for equipment regularly moved between sets or frequently used.
- Every 2 years – for stationary or low-use devices.
- After visible damage or repairs – always retest before use.
Many production designers schedule PAT testing alongside pre-production or set-up periods to ensure all equipment is safe before filming begins.
Is PAT Testing a Legal Requirement?
PAT testing itself is not explicitly required by law, but UK and European regulations mandate that all electrical equipment used at work must be safe. PAT testing is the recognised method to demonstrate compliance, and most studios, theatres, and insurance providers will expect proof.
Final Thoughts
As a production designer, your sets tell the story—but safety ensures that story is told without disruption. PAT testing ensures that your electrical equipment is reliable, safe, and professional, letting you focus on creating memorable visual experiences.
Because the only sparks on your set should come from your imagination—not faulty equipment.
