PAT TESTING · COMPLIANCE

How often is PAT testing required in Ireland?

It is the first question most facilities and office managers ask, and the honest answer surprises people: Irish law does not set a fixed PAT testing interval. Instead it sets a duty, and leaves the frequency to be decided by risk. Here is what that means in practice, and the intervals most Irish businesses actually work to.

There is no legally fixed PAT testing interval in Ireland. The law requires employers to keep electrical equipment safe and maintained (Safety, Health and Welfare at Work Act 2005 and the General Application Regulations 2007). The testing frequency is set by risk - the environment, the type of equipment and how heavily it is used. High-risk settings such as construction sites are checked every few months, while low-risk office equipment may only need a formal inspection and test every one to two years, supported by regular user checks and visual inspections in between.

Why there is no single interval

The General Application Regulations 2007 require electrical equipment to be safe, suitable for use and maintained in a safe condition. They do not name Portable Appliance Testing, and they do not state a frequency. That is deliberate: a drill on a wet construction site and a monitor bolted to an office desk carry very different risks, so a single interval would be wrong for one of them. The employer, or a competent person on their behalf, decides how often to inspect and test based on a risk assessment.

Typical frequency guidance

The intervals below are widely used industry guidance, not statutory requirements. Use them as a starting point and adjust to your own risk assessment, equipment condition and manufacturer advice.

The checks between formal tests

Formal inspection and testing is only one of three layers, and the other two happen far more often:

• User checks: staff look for obvious damage - frayed leads, cracked plugs, scorching - before use, every day.
• Formal visual inspection: a more thorough look by a competent person at set intervals, catching most faults without instruments.
• Combined inspection and test: the full PAT, using a tester, at the risk-based interval above.

Most electrical faults are found by looking, not by the instrument, which is why the visual layers matter as much as the test itself.

Keep the records

Whatever interval you set, record it. A register of equipment, test dates, results and the next due date is what demonstrates the duty has been met - to an auditor, an insurer or the HSA. Arkomax carries out PAT testing for businesses across Ireland and provides the records to match; see our PAT testing service.

Frequently asked questions

• Is annual PAT testing a legal requirement in Ireland?

  No. Annual testing is a common convention for many workplaces, but it is not set in law. Irish law requires equipment to be safe and maintained; the interval is decided by risk, so some equipment is tested more often than yearly and some less.
• Who decides how often to PAT test?

  The employer or duty holder, informed by a risk assessment and, usually, a competent person. The decision considers the environment, the type and age of equipment and how heavily it is used.
• Do offices really need PAT testing less often than sites?

  Generally yes. Office equipment is low-risk and rarely moved, so formal testing every one to two years is common, whereas 110V construction tools are typically checked every three months. Daily user checks still apply everywhere.
