There is no legally mandated PAT testing interval in Ireland. No twelve-month rule, no statutory frequency, nothing in legislation that says every appliance must be tested annually.
That surprises people, and it is often taken as good news. It should not be. A fixed interval would be simple to comply with. What the law actually asks for is a judgement — one you have to be able to defend.
What the regulations require
The obligation sits in the Safety, Health and Welfare at Work (General Application) Regulations 2007, S.I. No. 299, at Regulation 81, which deals with portable equipment. In summary, an employer must ensure that portable equipment is maintained in a manner fit for safe use, that equipment exposed to conditions causing deterioration liable to result in danger is periodically inspected by a competent person appropriate to the nature, location and use of the equipment, and that a competent person tests it and certifies whether it was safe on the day of the test.
Note the phrasing. Periodically, not annually. Appropriate to the nature, location and use — which is the legislation explicitly declining to give you a number, because a kettle in a quiet office and an angle grinder on a wet site are not the same risk.
The term “PAT testing” does not appear in Irish law at all. It is simply the recognised method by which employers meet the Regulation 81 duty.
Why “no fixed interval” is not a loophole
Flexibility cuts both ways. Because there is no prescribed frequency, you cannot point at a rule and say you followed it. You have to show that your interval was reasonable for the equipment and the environment — which means the interval needs to come out of a risk assessment rather than out of habit.
In practice, annual testing has become the accepted benchmark for general commercial premises, and insurers and enforcement bodies typically expect records no older than twelve months for standard portable appliances. But annual is a convention, not a requirement, and it is both too frequent for some equipment and nowhere near frequent enough for other equipment.
Setting intervals that make sense
The IET Code of Practice for In-Service Inspection and Testing of Electrical Equipment is the reference most competent testers work from, alongside HSA guidance. As a practical starting point:
- Stationary office equipment — desktop computers, monitors, printers that never move: every four to five years.
- Movable office equipment — fans, floor lamps, heaters: roughly every two years.
- IT equipment staff move regularly — laptops, chargers, docking stations: annually.
- Portable tools and extension leads — annually, or every six months in demanding environments.
- Kitchen and catering equipment — annually as a minimum, more often in heavy commercial use, which makes this a standing issue for hotels and hospitality.
- Site and workshop equipment — frequently much shorter intervals, driven by wear and exposure.
Two variables drive everything: how much the equipment gets handled and moved, and what conditions it operates in. Damp, dust, heat, vibration and being dragged across a floor all shorten the sensible interval.
The items that actually fail
Extension leads and multi-socket adaptors fail testing more often than almost anything else, and they are the items businesses overlook most consistently. They get daisy-chained, run under desks, trapped in doorways and pulled from the cable rather than the plug. Nobody records them on an asset list because nobody thinks of them as equipment.
If your office has a tangle of leads behind the desks, that tangle is in scope. So are kettles, microwaves, phone chargers, vacuum cleaners and anything else with a plug that staff use at work — a particular volume issue in schools and care homes.
The five-year record obligation
Testing without documentation does not demonstrate compliance. Records must be retained for five years, and an HSA inspector can request them at any time.
Practically, that means an appliance register — what was tested, when, by whom, with what result — rather than a stack of pass labels. Labels fall off, fade and get transferred between items. A written register is what survives.
Insurers also increasingly ask for this at renewal, and lapsed testing can affect a claim following an electrical fire.
What happens when something fails
This part is unambiguous. Where a competent person certifies that equipment was not safe on the day of the test, the employer must ensure it is not used until it has been made safe and certified.
Not set aside for later. Not used carefully in the meantime. Out of service. In reality, most failures are minor — a damaged lead, a poor termination inside a plug — and are repaired and retested on the spot by a tester carrying parts. But the equipment cannot go back into use on the strength of an intention to fix it.
A note on lower-voltage equipment
Regulation 81’s inspection requirement is framed around equipment supplied at a voltage exceeding 125V. Equipment running at 110V through a site transformer — common on construction work — is not specifically captured by that part of the regulation.
That does not put it outside the law. The general duty to maintain work equipment in a safe condition still applies, and 110V equipment on a site is typically in the harshest environment you will find. Excluding it from a testing programme on a technicality would be a difficult position to defend after an incident.
Where premises typically go wrong
- Testing everything on one date — convenient, but it means low-risk items are tested far more often than necessary while high-risk items wait too long.
- No asset register — new equipment bought during the year never joins the programme, so the register drifts out of date.
- Tenant and contractor equipment — in multi-tenant buildings and on serviced sites, nobody is clear who covers what.
- Relying on labels alone — no underlying record to produce when asked.
A defensible position
If an inspector asks why your interval is what it is, the answer that works is: we assessed the equipment, the way it is used and the environment it is used in, we set intervals accordingly, here is the register, and here are five years of records.
The answer that does not work is: we do it every year because that is what everyone does.
RFC carry out PAT testing for commercial premises across Dublin and Leinster, with a full written report and appliance register issued on completion. If you want your current intervals reviewed against the equipment you actually have, we can do that as part of a free site survey.
