What is BS7909?
BS7909 is the British Standard for temporary electrical systems used in entertainment and related industries. It sets out best practice for design, installation, inspection, and testing — ensuring electrical safety in fast-paced, high-risk environments like:
- Theatres & performance venues
- Festivals & live events
- Television studios & OB setups
- Film productions & location shoots
Compliance isn’t just a box-ticking exercise — it protects your crew, cast, audience, equipment, and reputation.
