Commercial Electrical Safety: What “Safe” Actually Means for Your Business

Why commercial electrical safety matters

Electrical faults are one of the most common causes of workplace fires and serious injury. In the UK, the core legal duty is that electrical systems must be constructed and maintained so they don’t present danger under the Electricity at Work Regulations 1989. 

The most common commercial risks (and why they’re missed)

• Overloaded circuits (extra equipment added over time)

• Poor repairs or DIY modifications

• Loose connections causing heat build-up

• Damaged cables and unsuitable extension leads

• Ageing distribution boards and inadequate protection

• Unrecorded changes after refurbishments or tenancy changes

Your practical safety checklist (what good looks like)

1. Routine visual checks: plugs, sockets, distribution boards, signs of heat/discolouration

2. Correct protection devices: RCDs/appropriate protective devices as required for the installation design under BS 7671 principles 

3. Periodic inspection & testing (EICR): confirm your installation remains safe over time (frequency depends on risk/use) 

4. Control of “change”: any new equipment/layout changes should trigger a check of loading and distribution

5. Competent contractors: ensure works are designed, installed and verified properly

Quick wins that reduce risk fast

• Replace damaged accessories immediately

• Label circuits properly

• Keep distribution boards clear and accessible

• Document changes (it’s usually the paperwork gap that causes compliance headaches later)
