Damaged Electrical Appliances at Work: When Should You Stop Using Them?
Damaged Electrical Appliances at Work: When Should You Stop Using Them?

Most electrical appliances in a workplace are used so often that they become part of the background.
A kettle in the staff room, a printer in the office, a lamp behind the counter, a charger near reception, a fan in a treatment room or a vacuum cleaner in a cupboard may all be used without much thought.
But if an appliance looks damaged, it should not simply stay in normal use until the next PAT testing visit.
For small businesses, landlords and letting agents, the sensible approach is simple: if something looks unsafe, stop using it, keep it away from normal use, and get advice before putting it back into service.
If you are unsure what might need checked across your premises, you can ask Wendy, Thorn PAT Testing’s online assistant, for a guide before requesting a confirmed quote.
Relevant for: small businesses, shops, cafés, offices, clinics, studios, landlords, letting agents, staff rooms, customer-facing premises and workplaces using everyday electrical equipment.
Do not wait if something looks unsafe
PAT testing is useful, but it should not be the only time anyone notices a problem.
If a member of staff spots damage to a plug, cable, casing or appliance, the item should be treated seriously straight away. It does not need to be dramatic. It simply means the appliance should be taken out of normal use until it can be checked properly.
That kind of common-sense response is part of keeping electrical equipment managed sensibly between formal checks.
Warning signs to look for
Some damage is easy to spot. Other problems are more subtle.
Things to take seriously include cracked casings, loose plugs, damaged cables, exposed inner wires, scorch marks, melted plastic, a burning smell, intermittent power, unusual heat, flickering, sparking, buzzing, or an appliance that has been dropped or knocked hard.
You do not need to diagnose the fault yourself. The important thing is to stop using the item if something does not look or feel right.
Staff should feel able to report problems
In a small business, electrical equipment may be used by several people during the week.
One person may notice a charger getting hot. Another may see a loose cable on a vacuum cleaner. Someone else may realise a kettle plug is cracked or a lamp flickers when moved.
Staff should feel able to mention these things rather than assuming someone else will deal with them. It is much easier to remove one suspect item from use than to ignore a visible warning sign.
Small appliances still matter
It is easy to take small items less seriously because they do not look like major equipment.
Phone chargers, laptop power supplies, desk lamps, fans, heaters, extension leads, speakers, card machine chargers and small kitchen appliances can all be used heavily in a workplace.
Our guide What Counts as an Appliance for PAT Testing? explains why everyday plug-in items should not be ignored just because they are small.
Staff rooms are a common risk area
Staff rooms and back rooms are often where damaged appliances go unnoticed.
A kettle may be used several times a day. A microwave may be old but still working. A portable heater may only come out in winter. A vacuum cleaner may have a worn cable but still be used because it is kept in a cupboard.
These items can be easy to overlook because they are away from customers, but they are still part of the electrical equipment being used in the workplace. I have covered this separately in PAT Testing for Staff Rooms: Kettles, Microwaves and Everyday Equipment.
Do not keep using an item just because it still works
One of the most common mistakes is assuming an appliance is safe because it still turns on.
An item can still work while having visible damage, a loose connection, a damaged plug, a strained cable or signs of overheating.
If the appliance looks damaged, smells unusual, gets hotter than expected or behaves inconsistently, it should be removed from normal use until it has been checked or replaced.
What should you do with a damaged appliance?
If you find a damaged electrical appliance, the first step is to stop using it.
Unplug it safely if it is safe to do so, keep it separate from equipment still in use, and make sure staff know not to plug it back in. If there is any immediate concern, do not continue using the item.
The appliance can then be repaired by a competent person, replaced, removed from the premises, or checked as part of a PAT testing visit if appropriate.
What if it fails during PAT testing?
If an appliance fails during PAT testing, it should not simply be put back into normal use.
The failed item should be clearly identified, recorded, and dealt with. In many cases, the practical options are repair, replacement or removal from service.
I have explained this in more detail in What Happens If an Appliance Fails a PAT Test?.
New appliances should still be checked visually
Damage is not only an issue with old equipment.
A new appliance may be damaged during delivery, storage, installation or setup. Packaging may be damaged, a cable may be trapped, or a plug may not look right.
New items should normally arrive in safe condition, but they should still be looked over before regular use. Our guide Do New Appliances Need PAT Testing Straight Away? covers this in more detail.
Landlords should check supplied appliances between visits
For landlords, the focus should stay on portable or movable electrical appliances supplied for tenant use.
That might include a fridge, washing machine, microwave, kettle, toaster, lamps, television, vacuum cleaner, portable heater or fan.
If a supplied appliance is reported as damaged, it should be dealt with before it continues to be used. Thorn PAT Testing has more information on landlord PAT testing and letting agent PAT testing.
Customer-facing businesses should act quickly
In customer-facing premises, damaged electrical equipment can be especially awkward because it may be visible or used during the working day.
A shop, café, clinic, barbershop, opticians, studio or small office may have equipment in areas used by staff and customers. If an item looks damaged, it is better to remove it from use than to leave it sitting in the normal working area.
Thorn PAT Testing provides business PAT testing for local workplaces, including shops and retail premises, cafés and restaurants, and other small business environments.
Keep a note of what has been removed
If you remove an appliance from use, it is worth keeping a simple note of what happened.
You do not need a complicated system. A basic note can show what the item was, where it was used, what the concern was, and whether it was repaired, replaced or removed.
This helps keep your appliance records clearer and makes the next PAT testing visit easier. Our guide Why Small Businesses Should Keep an Appliance List explains why even a simple appliance record can be useful.
Annual PAT testing helps keep records current
Appliances change over time. Items are added, moved, replaced, damaged, repaired or removed.
An annual PAT testing visit gives many small businesses, landlords and letting agents a simple routine. The equipment is checked, failed items are recorded, and the digital report gives a clearer picture of what is being used across the premises.
You can view Thorn’s PAT testing prices or ask Wendy for a guide price before requesting a confirmed quote.
Wendy can help you work out what might need checked
Wendy can help before booking by asking simple questions about your premises, appliance count and type of job.
She can give a guide and point you towards the right next step. The final confirmed quote, visit and report still come from Thorn PAT Testing.
If you have damaged items or are unsure what should be included, Wendy is a useful starting point before Nick confirms the booking details.
Thorn PAT Testing’s approach
