Is PAT Testing a Legal Requirement? 5 Things That Clears Up
Every office has a drawer of equipment with little coloured stickers on it, and somebody who books an annual visit because that is what happens.
The law does not require any of that. It requires something related but different, and the gap between the two costs organisations money, produces a false sense of compliance, and occasionally leaves genuinely dangerous equipment in service because the sticker was current.
This is not an argument against testing. It is an argument for doing the thing the law asks for, which is usually less expensive and more effective.
Five things.
1. The law says maintain, not test
Start with the provision, because it is short and it does not mention testing at all.
Regulation 4(2) of the Electricity at Work Regulations 1989 provides that, as may be necessary to prevent danger, all systems shall be maintained so as to prevent, so far as is reasonably practicable, such danger.
That is the duty. It requires maintenance sufficient to prevent danger, and it says nothing about how, by whom, how often, or with what equipment. Regulation 5 of the Provision and Use of Work Equipment Regulations 1998 adds a parallel duty to maintain work equipment in an efficient state, in efficient working order and in good repair.
Neither instrument contains the phrase "portable appliance testing". HSE addresses the question directly in its guidance on portable appliance testing, and the position is that the law sets a goal and leaves the method to the duty holder.
2. Where the annual sticker came from
Useful context, because it explains why the myth is so durable.
Portable appliance testing is a method, developed and marketed as a way of discharging the maintenance duty. It is a perfectly legitimate method. What happened is that a method became, in common understanding, the requirement itself, helped along by a service industry with an interest in annual visits.
The practical consequence is that organisations buy a schedule rather than an assessment. They test everything at the same interval regardless of risk, they record that testing happened, and they treat the resulting label as evidence of compliance with a duty expressed in entirely different terms.
3. What an office actually needs

The constructive part, and for most offices it is a three-tier arrangement.
User checks. The most effective single control available, and it is free. Anybody using equipment looks at it: damaged cable, cracked plug, scorch marks, loose connections, equipment that has got wet or been knocked about. Most faults that cause harm are visible, and the person using the item is the one most likely to see them.
Formal visual inspection. Someone competent, though not necessarily an electrician, carrying out a more deliberate check at intervals. This catches the majority of the remaining faults and requires no test equipment.
Combined inspection and testing. Instrument testing, where the risk justifies it. HSE's guidance on maintaining portable electrical equipment sets out the approach for lower-risk environments, and an office is a lower-risk environment.
Read those three together and the shape is clear. In an office, most of the work is looking, and the instrument testing is a smaller, targeted exercise rather than a blanket annual sweep.
4. Frequency is risk-based, and "annually" is not in the law
The question everybody asks, and the answer is unsatisfying in a useful way.
There is no legally prescribed interval. The appropriate frequency depends on the type of equipment, the environment it is used in, how it is handled and how it has performed.
That produces a sensible spread in an office. A desktop machine that sits on a desk and is never moved presents a different risk from an extension lead dragged around a meeting room, a kettle in a busy kitchen, or a power tool kept for maintenance. Applying one interval to all of them is either wasteful at one end or inadequate at the other.
Two practical points. Equipment brought in by employees is a category to have a position on, because it is used at work and nobody has assessed it. And new equipment does not need testing on arrival simply because it is new; what it needs is a check that it is suitable and undamaged.
5. Stickers are not the point, and records are
Two closing clarifications.
Nothing requires a label on an appliance. Labels are an administrative convenience, and their risk is that they become the evidence: an item with a current sticker and visible damage is more likely to stay in service than one with no sticker at all.
What is worth keeping is a record of what you decided and what you did: the equipment you hold, the regime you applied to each category, the reasoning, and the outcomes including faults found and items withdrawn. That record demonstrates maintenance under a duty expressed in terms of preventing danger, which a schedule of test dates does not by itself.
The broader electrical duties, including fixed installation testing, sit alongside this and are covered in our work on the Electricity at Work Regulations. HSE's overview of electrical safety covers the wider framework.
The five, in short
| Question | Common belief | Actual position |
|---|---|---|
| Is it required | PAT testing is the law | Maintenance is the law; PAT is one method |
| Why everyone does it | It has always been required | A method became the perceived requirement |
| What an office needs | Annual testing of everything | User checks, visual inspection, targeted testing |
| How often | Annually | Risk-based, by equipment type and use |
| Stickers | Evidence of compliance | Not required; the record is what matters |
The third row is where most organisations can save money and improve safety simultaneously, which is rare enough to be worth acting on.
For international groups
Two considerations.
The British position is unusually permissive and unusually misunderstood, which is a combination worth knowing. The duty sets an outcome and leaves the method open, and a great many British organisations have nonetheless converged on one method.
Elsewhere, examination is frequently prescribed. Several jurisdictions covered in this series require periodic testing of electrical installations and work equipment at set intervals, and in some cases by a person holding a specified qualification. Croatia and Slovenia both require prescribed examinations, and Latvia, Lithuania and Bulgaria operate their own regimes.
So a group standard saying "test annually" is over-specified for Britain and possibly under-specified elsewhere, which is the reverse of what most groups assume. Holding the equipment inventory, regime and records for every site in one register is where health and safety consultants and software are worth more together than either alone, and periodic health and safety audits establish whether a testing programme is doing anything beyond generating labels.
Where Arinite fits
Arinite works out what the duty actually requires for a particular workplace, which for electrical equipment in an office is usually less testing and better looking. We support 1,500+ businesses across 50+ countries and protect 100,000+ employees, with 95%+ client retention over 15+ years. Our health and safety consultants work extensively with legal, finance and banking and IT and software organisations, including those with laboratories and hardware environments where the answer is genuinely different.
Where sites span several countries, our global health and safety consultants establish what each jurisdiction prescribes and who may carry it out, and our international health and safety consultants keep that current.
If your organisation pays for annual testing of every appliance and has never assessed whether that is what the duty requires, a free gap analysis is the right place to start.
