Electricity at Work Regulations 1989: What Employers Actually Need to Do

Most UK employers can name their fire safety duties and their COSHH obligations without much prompting, but ask what the Electricity at Work Regulations 1989 actually require and the answers get vaguer fast — often reduced to "get PAT testing done" and left at that. The regulations themselves don't mention PAT testing by name at all. They set a broader, ongoing duty that a once-a-year sticker doesn't fully discharge.

What the regulations actually require

The Electricity at Work Regulations 1989 place a duty on employers, the self-employed, and anyone with control over an electrical system to ensure that system is "constructed, maintained and used in such a way as to prevent danger, so far as is reasonably practicable." "Danger" is defined broadly — any risk of injury, covering electric shock, burns, and injury arising from fire or explosion caused by electricity. This is a maintenance duty, not a one-off compliance certificate: an electrical system that was safe when installed but has since degraded, been modified poorly, or is being used outside its design limits is no longer compliant, regardless of what any historical test result says.

Where PAT testing actually fits

Portable Appliance Testing (PAT) is a practical method many employers use to demonstrate that portable electrical equipment is being maintained, but it isn't named or mandated by the regulations themselves. The legal duty is the outcome — equipment maintained to prevent danger — not a specific testing regime with a specific name or a specific frequency. In practice, this means an employer can't treat an annual PAT test as automatically sufficient if equipment is heavily used, works in a harsh environment, or shows visible signs of wear between scheduled tests; equally, low-risk equipment in a low-risk office setting may reasonably need testing less often than a fixed annual assumption suggests. The right approach is a risk-based inspection and maintenance regime, not a blanket calendar rule applied without judgment.

Competent persons

Regulation 16 requires that anyone carrying out work on or near electrical equipment where technical knowledge is needed to avoid danger must possess that knowledge and experience, or work under the supervision of someone who does. This applies to installation, maintenance, and inspection work alike. An employer who allows untrained staff to carry out electrical repairs or fault-finding — even informally, even "just this once" — is exposed regardless of whether anything goes wrong on that particular occasion; the duty is about the competence of the person doing the work, not the outcome of any single job.

Fixed installations versus portable equipment

The regulations cover the full electrical system, not just plug-in appliances. Fixed wiring, distribution boards, and permanently installed equipment fall under the same maintenance duty as portable kit, and typically need periodic inspection and testing by a qualified electrician on a schedule appropriate to the building's use and electrical loading — commercial and industrial premises generally need more frequent fixed-wiring inspection than office environments with lighter, more predictable use. Treating "electrical safety" as synonymous with "PAT testing the kettle and the laptop chargers" misses the larger and often higher-risk part of the system.

Building this into a wider safety programme

Electrical safety duties sit most naturally alongside an organisation's wider work equipment and maintenance obligations rather than as an isolated annual task. A practical programme documents what's been inspected, by whom, against what standard, and what happened to anything that failed — the same documentation discipline that PUWER compliance requires for work equipment generally. Staff also need a clear, simple route to report a visibly damaged plug, cable, or socket rather than waiting for the next scheduled inspection to catch it.

FAQ

Is PAT testing a legal requirement under UK law?
Not by name. The Electricity at Work Regulations 1989 require electrical equipment to be maintained to prevent danger; PAT testing is a common and practical way many employers demonstrate that duty, but the regulations don't specify PAT testing itself or a fixed testing interval.

How often should electrical equipment be tested?
There's no single legally fixed interval. The right frequency depends on the type of equipment, how it's used, and the environment it's used in — a risk-based approach, rather than a blanket annual rule, is what the regulations actually call for.

Who can carry out electrical maintenance work?
Only someone with the technical knowledge and experience to do the work safely, or someone working under the supervision of a person who has that competence, per Regulation 16.

Do the regulations only cover portable appliances?
No. They cover the whole electrical system, including fixed wiring and installations, not just plug-in equipment.

Electrical safety compliance is an ongoing maintenance duty rather than an annual paperwork exercise, and understanding that distinction is what separates a genuinely compliant programme from one that just looks compliant on paper.
