Electrical equipment is part of everyday working life, but faulty or misused kit is also one of the most common causes of workplace fires. This guide walks you through the electrical safety checks every business should be doing, from the equipment you buy to the day-to-day habits that keep your team safe. It also answers the question we hear most often: is PAT testing a legal requirement, and how often do you really need to do it?

On our health and safety training courses, one question comes up again and again: what electrical safety checks should my business actually be doing? It is a fair thing to ask. Since 2009, fires caused by faulty or misused electrical equipment have risen by around a third, which is no great surprise when you think about how much we all rely on technology at work.

A serious fire can sink a business or, at the very least, cripple it for months. The good news is that preventing one is largely common sense, and putting the right measures in place rarely costs much at all.

It starts before you buy

Good electrical safety begins before you have spent a penny. Start by thinking about what the equipment is for and where it will be used.

An electrical kit carries more than one rating. You will know about power ratings, but there is also the IP, or ingress protection, rating, which tells you how well something keeps dust and moisture out. Match the IP rating to the environment. An IP67 item, for instance, is both dust-tight and safe to be submerged in water. Once you have found what you need, check that it carries a CE mark before you buy.

Sue recommends: Match the IP rating to the job before you look at the price. Kit used outdoors, or in a damp or dusty area, needs a higher rating than something that lives on an office desk. Get this right at the point of purchase and you save yourself both money and risk further down the line.

Always read the manufacturer’s instructions

When the equipment arrives, read the manufacturer’s instructions, keep them somewhere your team can find them, and then actually follow them. A surprising number of fires start simply because guidance on something like ventilation clearances or regular cleaning has been ignored.

It also pays to stick with the cables and chargers that came with the equipment. Cheaper replacements are tempting, but substandard alternatives usually cost you more in the long run.

Train your staff in electrical safety

Your team are your first line of defence, so arm them with a few simple rules:

  • Do not leave appliances charging unsupervised for long periods or for longer than the manufacturer specifies.
  • Do not try to charge a battery that looks damaged.
  • Do not cover items while they charge, as they give off heat. Keep them well away from anything flammable.
  • Do not leave large appliances running overnight or in an empty building unless they are designed for it, such as a fridge.
  • Do not overload sockets. Outlets, extension leads and adapters all have a limit to the number of amps they can handle.

Electrical safety is one of the topics covered on our Level 2 Health and Safety course, which is a good grounding for anyone responsible for a workplace.

It also pays to have everyone give equipment a quick once-over before they use it, watching out for:

  • burn marks or stains around plug sockets, which can point to overheating
  • frayed or worn cables and wires
  • flickering lights, blown fuses, or circuit breakers that trip for no obvious reason.

Anything that looks off should be reported, so a qualified electrician can take a proper look.

Keep up regular inspection and maintenance

Alongside those everyday checks, make sure regular inspection and maintenance schedules are followed. They should confirm that:

  • equipment used in hazardous conditions, such as extreme weather, temperatures or corrosive environments, is properly protected
  • Damaged sections of cable are replaced completely, rather than patched up with insulating tape
  • equipment is fitted with the correctly rated fuse
  • cables are joined with proper connectors, rather than connector blocks wrapped in tape or wires twisted together
  • Faulty equipment is taken out of use straight away, labelled so no one uses it, and inspected by a competent person.

Finally, fit RCDs between your electrical items and the supply, particularly on higher-risk kit, so that the instant a fault occurs, the supply is cut off from the equipment.

Is PAT testing a legal requirement?

This one comes up more than almost any other, so let us settle it. PAT testing is not a legal requirement. It can be a sensible way to show you are keeping on top of your electrical equipment, but no law forces you to do it. The HSE even reviewed its own PAT testing policy back in 2011 and decided some of its equipment did not need testing at all.

That is not a green light to cancel everything, though. You should only scale back your testing once a risk assessment says it is safe to. Look at the portable electrical equipment your business relies on, how it is used and where, and let that shape your inspection and testing regime.

So what actually is PAT testing?

Portable appliance testing, or PAT, simply means checking electrical appliances and equipment to make sure they are safe to use. A full test combines a visual inspection with a more detailed check using specialist equipment, covering earth continuity, lead polarity and insulation resistance.

The catch is that a PAT test only tells you the equipment was safe at the moment it was tested. Say a power drill passes in the morning, then gets dropped and damaged on a job that afternoon. The plug still wears an in-date sticker, but the tool is no longer safe, and if nobody flags the damage, the next person could pick up a faulty piece of kit. That is exactly why PAT testing works best as one part of a wider habit of inspection, testing and defect reporting.

Sue recommends: Do not rely on a PAT sticker alone. Build a simple defect reporting habit into your team’s day, so anything dropped, damaged or behaving oddly is taken out of use and flagged straight away. A quick visual check before use often catches the very problems a once-a-year test never would.

How often should you PAT test?

There is no one-size-fits-all answer, because three things decide how often testing is needed:

  • The risk level of the working environment
  • The electrical class of the appliance
  • The category of the appliance.

The HSE reviewed its own office testing for exactly this reason. A lot of its equipment, such as desktop computers, is class 1 but sits in a low-risk environment and rarely moves. That combination, alongside regular visual checks by the people using it, meant the gap between tests could safely be widened. A wall-mounted television used only to display information may not need PAT testing at all, as it is class 2, which is safer than class 1, and never moves.

At the other end of the scale, a power tool used in dusty conditions and thrown in the back of a van between jobs needs testing far more often, perhaps every six months.

What the law does require

PAT testing may be optional, but electrical safety is not. The Electricity at Work Regulations 1989 cover all electrical systems and equipment. In plain terms, you need to understand the fire and safety risks your electrical equipment carries and take sensible steps to keep them low. Regular checks, a well-trained team and proper maintenance are how you meet that duty day to day.

Need a hand?

Electrical safety does not have to be a headache. If you want your team to be confident around the equipment they use every day, our health and safety training covers the essentials, and a free health and safety review is a simple way to spot any gaps before they become a problem.
