7 PAT Testing Myths UK Businesses Still Believe

PAT testing is one of the most misunderstood areas of UK workplace compliance. Walk into ten offices, restaurants or warehouses and you’ll hear ten different explanations of what’s required, who has to do it, and how often. Most of them are wrong — and the consequences of acting on the wrong information can be serious.

PAT testing myths don’t just create confusion. They create the conditions for invalid insurance claims, increased exposure during HSE inspections, and businesses paying for the wrong kind of testing on the wrong kind of schedule. Getting it right matters — and that starts with knowing what’s actually true.

Here are the seven PAT testing myths we hear most often from UK businesses, and why each one puts you at risk.

Myth 1: “PAT testing isn’t a legal requirement, so we don’t need to do it”

This is the most dangerous myth on the list — because the first half is technically true, and businesses use it to justify doing nothing.

It’s correct that no UK law names “PAT testing” as a mandatory activity. But that misses the point entirely. The Electricity at Work Regulations 1989, the Health and Safety at Work etc. Act 1974, and the Provision and Use of Work Equipment Regulations 1998 all place a hard legal duty on employers to ensure electrical equipment is maintained in a safe condition and doesn’t cause danger to anyone using it.

PAT testing is the industry-standard, HSE-recognised, court-recognised, insurer-recognised method of meeting that duty. If an accident happens and you can’t produce evidence of a competent inspection and testing regime, you won’t be able to demonstrate compliance with the regulations that do apply by name. The fines run into unlimited sums, the prosecutions are real, and insurers will refuse claims involving electrical fires or shocks where you can’t show evidence of maintenance.

“It’s not legally required” is the most expensive sentence in UK workplace compliance: fines under the Electricity at Work Regulations are unlimited, and the business liability when electrical incidents occur can run into six figures.

The duty is real. PAT testing is how you discharge it.

Myth 2: “We can just do it ourselves with a tester off Amazon”

You can buy a PAT tester online for under £200. That doesn’t mean you should be running your own programme with it.

HSE guidance requires testing to be carried out by a competent person — someone with sufficient knowledge, training, and experience to do the job correctly and interpret the results. That second part is where DIY programmes fall apart. A tester gives you readings; competence is knowing what those readings mean, what to do when they fall outside acceptable ranges, how to identify Class I versus Class II equipment, when to apply a flash test, and how to keep records that will stand up to scrutiny.

When something goes wrong — and the question is when, not if, across a whole equipment estate — “competent” is what gets tested in court. A facilities manager with a weekend’s training and a budget tester is a long way short of what an HSE inspector or an insurance loss adjuster will accept as evidence of competence. Accredited providers carry the qualifications, the calibrated equipment, the indemnity insurance, and the audit-ready documentation that turn a test into actual proof of compliance.

Myth 3: “If it has a sticker, it’s safe”

A PAT label tells you the appliance passed a test on a specific date. It does not tell you the appliance is safe today — and treating the sticker as a guarantee is how businesses get caught out.

Damage happens between tests. Cables get trapped under desk legs. Plugs get yanked from sockets. Kettles get dropped, extension leads get daisy-chained, chargers get coiled until the insulation fails. A label from twelve months ago is worth nothing if the cable failed yesterday.

This is exactly why a proper PAT regime isn’t just an annual visit — it’s a layered system. Formal inspection and testing by a competent provider sits alongside trained user checks, defined reporting routes for damaged equipment, and risk-based scheduling that targets higher-risk items more often. That layered approach is what HSE guidance actually expects. The sticker is one piece of evidence, not the whole answer.

Myth 4: “Everything has to be tested every 12 months”

The reality: There’s no legal requirement for universal annual testing — but for most office and commercial environments, annual testing is the sensible default, and here’s why.

HSE guidance is built around risk assessment, not fixed intervals. Technically, the right interval depends on equipment class, environment, and how often items are moved or handled. A desktop PC in a quiet office carries different risk than a power drill on a construction site.

But here’s what the “risk-based intervals” guidance doesn’t account for: equipment gets knocked, cables get damaged when furniture moves, plugs get cracked when items are relocated, and damage accumulates gradually throughout the year. In a typical office, you don’t know which kettle got dropped last month, which monitor cable got trapped behind a desk, or which extension lead has been moved three times since the last test.

Annual testing captures that real-world wear and tear. It’s not about ticking a regulatory box — it’s about catching the damage that happens during normal use before it becomes a safety issue. The alternative is trying to maintain visibility over hundreds of items in active use and reliably identifying when each one needs attention. Most businesses don’t have that level of operational oversight, which is why annual cycles work.

The actual myth is assuming annual testing is legally mandated. It isn’t. But it’s often the most defensible, practical approach — not because the regulations demand it, but because it creates a reliable safety net that catches gradual equipment deterioration before it becomes dangerous.

A competent PAT contractor will document why annual testing makes sense for your operation, which equipment types might justify shorter intervals (high-use or harsh-environment items), and which could safely extend longer (fixed, rarely-moved equipment). The schedule becomes defensible because it’s based on your actual risk profile, not just defaulting to 12 months because “that’s what everyone does.”

Myth 5: “Brand new equipment doesn’t need any attention”

It’s true that new electrical equipment from a reputable UK supplier is presumed safe and doesn’t need to be PAT tested before it’s put into service. But “presumed safe out of the box” isn’t the same as “out of scope forever.”

New items still need to be:

• Added to your asset register with purchase date and location

• Subject to user visual checks from day one

• Brought into your normal testing schedule based on a proper risk assessment of how and where they’re used

The myth gets businesses into trouble because new equipment quietly drifts off the radar. A laptop charger bought last March is no longer new by next March, but if it was never logged it won’t be in your testing cycle either. The same applies to anything that has been repaired — repaired equipment must be tested before it goes back into use, and a structured compliance programme is what catches it.

Many businesses simplify this by having their PAT provider test all new equipment at the point of first service visit. This ensures new items are immediately added to the asset register, formally documented from day one, and brought into the regular testing cycle without relying on internal tracking. For organisations that don’t have the capacity to run their own user visual checks or maintain detailed equipment logs, this approach removes the administrative burden while ensuring nothing falls through the gaps.

This is what good asset management looks like, and it’s a core part of what a professional PAT provider sets up for you. Without it, your compliance is only as good as the items someone happened to remember.

Myth 6: “Battery-powered and low-voltage items aren’t our problem”

Historically, PAT testing focused on mains-powered equipment, and battery-powered items were largely seen as out of scope. That position is no longer safe to take.

The 2024 amendments to IET guidance updated the position on lithium-ion battery equipment — e-bikes, e-scooters, large power-tool battery packs, and similar items — after a string of high-profile fires. The chargers for these items are mains-powered and have always been within PAT scope. The batteries themselves now need to form part of a broader electrical safety risk assessment, including safe charging locations, storage, and procedures for damaged or swollen units.

Most businesses haven’t caught up. Many don’t realise the guidance has moved at all. This is exactly the kind of regulatory shift where working with a provider that tracks IET and HSE updates pays for itself — because the first time a lithium-ion battery fire happens in a UK workplace and the insurer asks for evidence of a current risk assessment, the businesses without one will find out the hard way.

Myth 7: “Our landlord handles all of this”

A myth especially common in serviced offices, co-working spaces, and leased commercial premises — and one of the most expensive to discover the truth about.

Your landlord is responsible for the fixed electrical installation — the wiring, consumer unit, sockets, and fixed equipment that belongs to the building. That’s typically evidenced by an EICR (Electrical Installation Condition Report), which commercial premises generally need every five years.

What the landlord is not responsible for is your kettles, your monitors, your phone chargers, your printers, your extension leads, your fans, your microwaves, and every other appliance your business has brought onto the premises. Those are yours. They fall under your duties as an employer, and PAT testing is how you demonstrate you’ve kept them safe.

This is one of the most common compliance gaps we see — businesses that genuinely believed their tenancy covered everything, and find out it doesn’t only when their insurer asks for evidence after a claim, or when an HSE inspector turns up. The split between EICR (the building) and PAT testing (your equipment) is a fundamental one, and getting it wrong leaves you fully exposed for everything plugged into the wall.

In serviced offices and co-working spaces, arrangements vary. Some landlords include PAT testing of shared equipment (kitchen appliances, printers, meeting room tech) as part of the service package. Others don’t. The critical step is to get it in writing — which equipment is covered under your tenancy agreement and which falls under your responsibility as the occupier. Without that clarity, you can both assume the other party is handling it, and neither is.

The cost of getting it wrong

The thread running through all seven myths is the same: PAT testing isn’t optional, it isn’t a one-size-fits-all calendar exercise, and it isn’t something most businesses can credibly manage on their own.

The Electricity at Work Regulations 1989 don’t prescribe how you keep your appliances safe — they require that you do, that you can prove it, and that your approach is proportionate to the risk. In practice that means:

• A proper risk assessment that sets sensible, defensible testing intervals

• A competent provider with the qualifications, calibration, and accreditations to back up the work

• An asset register that tracks every item from purchase to disposal

• Records that will stand up to HSE, your insurer, and your auditors

• Ongoing oversight that adapts when your equipment, premises, or working patterns change

Get those things right and the myths stop mattering. Get them wrong and you’re relying on hope — which is what every prosecuted business was doing before the accident.
