Electricity at Work Regulations: The Duties You Can Never Argue With, and the Ones You Can

Most health and safety law is softened by one famous phrase: "so far as is reasonably practicable," the qualifier that lets cost and difficulty be weighed against risk. The Electricity at Work Regulations 1989 are unusual, and understanding them properly starts with noticing why: several of their duties carry no such softening. They are absolute. Electrical danger must be prevented, full stop, and the employer's protection is not "we did what was proportionate" but a separate defence of having taken all reasonable steps and exercised all due diligence.

That two-tier structure, the duties you can never argue with and the ones you can, is the clearest way to understand what the regulations demand, and it is how this guide is organised. Along the way it settles the most repeated myth in workplace electrical safety, the one about PAT testing being a legal requirement, because the truth is more interesting and more useful. The HSE's electrical safety guidance and its memorandum on the regulations, HSR25, stand behind everything here.

Who the regulations bind

The duties fall on employers, the self-employed, and, distinctively, on employees themselves in respect of matters within their control, which reflects electricity's nature: the person nearest the panel often holds the danger in their hands. The regulations apply wherever electricity is used at work, from the office full of desktop equipment to the plant room, and they cover systems, equipment and the work done on or near them.

The scope point worth underlining: this is not a set of rules for electricians. Every employer whose people so much as plug things in is inside it, and the office that has never read the regulations is bound by them exactly as firmly as the factory that has.

The absolute tier: duties that admit no argument

The heart of the regulations is a set of duties stated without qualification. Electrical systems must be constructed and maintained so as to prevent danger. Equipment must not be used where its strength and capability may be exceeded so as to give rise to danger. Conductors that could cause danger must be insulated or otherwise protected. Precautions must be taken against the risk of injury from charged equipment. Stated plainly: danger prevented, not danger reduced where convenient.

What stands behind an employer accused of breaching an absolute duty is the regulations' own defence: proof that all reasonable steps were taken and all due diligence exercised to avoid the offence. Read those two sentences together and the practical meaning appears: the absolute tier converts electrical safety from a cost-benefit conversation into an evidence question. The employer's position is only ever as good as what it can show it did, systematically and in advance, which is why maintenance regimes, inspection records and competence evidence are not administration in this area but the defence itself.

The qualified tier: where reasonableness returns

Other duties in the regulations carry the familiar qualifier, applying so far as is reasonably practicable: the adequacy of working space, access and lighting around electrical equipment, among others. Here the usual balancing returns, and proportionate judgement is the standard.

The two tiers are not a trivia point; they set your priorities. A business with limited attention should spend it first on the absolute tier, the condition of systems, the suitability of equipment, the protection of conductors, because that is where the law left itself no flexibility and left the employer only the diligence defence.

The live working rule: three conditions or no

One duty deserves its own section, because it is the sharpest in the regulations. Work on or near live conductors is prohibited unless three conditions are all met: it is unreasonable in all the circumstances for the equipment to be dead, it is reasonable for the work to happen live, and suitable precautions are in place to prevent injury. The default, in other words, is dead working, proved dead by proper isolation, not assumed dead by the switch position.

The rule exists because the alternative kills. "It will only take a second" is the sentence that precedes a striking share of electrical injuries, and a business's real position on the live working rule is visible not in its policy but in what its people do when isolation is inconvenient.

The PAT myth, settled

Now the question every office asks: is PAT testing a legal requirement? The precise answer: no law names PAT testing, and no law sets an annual frequency. What the regulations require, absolutely, is that equipment be maintained so as to prevent danger. Portable appliance testing is one well-established way of meeting that duty for plug-in equipment, alongside user checks and visual inspection, and the HSE says this in terms, including that the frequency of inspection and testing should follow the risk, the office laptop charger and the site extension lead are not the same case, and that blanket annual testing of everything is often more than the risk requires.

The myth matters in both directions. Businesses over-buy calendar-driven testing as a compliance ritual, and, more dangerously, treat the sticker as the discharge of the duty, when the duty is the ongoing condition of the equipment, which a user check catches the day the cable frays, eleven months before the next sticker. Maintenance is the requirement; PAT is a tool.

What a compliant electrical regime looks like

Assembled, the regime is recognisable: an inventory of your electrical systems and equipment; maintenance and inspection scheduled by risk, fixed installations periodically inspected by competent persons, portable equipment covered by the user-check, visual-inspection and testing mix the risk justifies; defect reporting people actually use, with faulty kit withdrawn rather than tolerated; competence established for anyone doing electrical work, matched to the work's nature; isolation and permit procedures where the live working rule could ever be tested; and records throughout, because on the absolute tier the records are the defence.

That word "records" is where scale enters. One office's regime fits in a folder; an estate's worth, every fixed installation date, every equipment class and its frequency, every defect and withdrawal, every competence check, current across sites and countries, is a system, and it is where consultants and software carry it together: qualified health and safety consultants setting the risk-based frequencies and competence standards, the platform keeping every record live and findable, and regular health and safety audits testing that the regime on paper is the regime on the wall. Internationally, the same current meets different rulebooks, and international health and safety consultants keep one world-class standard running through every local version, aligned with frameworks such as ISO 45001.

Where Arinite fits

Arinite has spent 15+ years building electrical safety regimes that stand on the tier where the law allows no argument.
