What Happens If an Appliance Fails a PAT Test?

One of the common worries with PAT testing is what happens if something fails.

For small businesses, landlords and local workplaces, a failed PAT test can sound more serious than it usually is. In most cases, it simply means an appliance has a safety concern that needs to be clearly identified, removed from use, repaired or replaced where appropriate, and recorded properly.

A fail does not mean panic. It means the issue has been found before it causes a bigger problem. That is one of the main reasons PAT testing is useful in the first place.

A failed PAT test is not the end of the world

If an appliance fails, the important thing is that it should not continue to be used until the problem has been dealt with.

The item should be clearly marked as failed, removed from service if necessary, and recorded on the PAT testing report. Depending on the fault, it may be possible to repair the appliance, replace a damaged lead, fit the correct fuse, or simply remove the item from use altogether.

The key point is that the failure is identified and documented, rather than being left unnoticed in the workplace.

Why appliances can fail PAT testing

Appliances can fail for a number of reasons. Some are obvious during the visual inspection, while others may only show up during electrical testing.

Common reasons can include:

• damaged plugs
• cracked or damaged appliance casings
• frayed, crushed or exposed cables
• loose cable grips
• incorrect fuse ratings
• signs of overheating or scorch marks
• failed earth continuity tests
• failed insulation resistance tests
• equipment being unsuitable for the environment it is used in

Some faults are simple to deal with. Others may mean the appliance should be replaced. Either way, the business now has a clear record of the issue.

Visual inspection failures

Not every failure comes from an electrical test reading. Many problems are found before the tester is even used.

A visual inspection may identify obvious damage such as a cracked plug, a loose cable grip, a damaged lead, exposed wiring, a broken casing or signs that an item has overheated.

In some cases, an appliance may fail at the visual inspection stage because it is clearly not safe to continue using. That is why the visual inspection is such an important part of the process.

Electrical test failures

Where electrical testing is required, the appliance may be checked using suitable test equipment. The type of test depends on the appliance and its construction.

For example, some appliances may need an earth continuity test, while others may require an insulation resistance test or other suitable checks. These tests help identify faults that may not be obvious just by looking at the item.

If the appliance does not meet the required result, it should be recorded as failed and dealt with appropriately.

What happens after an appliance fails?

If an appliance fails a PAT test, the usual steps are:

• the item is labelled or marked as failed
• the business is told what the issue is
• the appliance should be removed from use
• the failure is recorded on the report
• the item can then be repaired, replaced or disposed of where appropriate

This gives the business a clear and sensible way to manage the risk. The important thing is that failed equipment is not left in normal use without action being taken.

Can a failed appliance be repaired and retested?

Sometimes, yes.

A failure does not always mean the appliance has to be thrown away. If the problem is minor and can be repaired safely, the item may be repaired by a suitable person and then retested before being put back into use.

Other items may not be worth repairing, especially if they are old, damaged, low value or showing signs of repeated problems. In those cases, replacement may be the safer and more practical option.

Why clear records matter

Clear records are one of the most useful parts of PAT testing.

If an item fails, the report should show what appliance was checked, what result was recorded, and what issue was identified. This gives the business, landlord or workplace a clear record of the action needed.

For small businesses, landlords and letting agents, this helps show that electrical equipment is being managed properly rather than ignored.

Failed items should not be left in use

The most important point is simple: if an appliance has failed, it should not be used until the issue has been resolved.

It can be tempting to keep using something if it appears to work, but electrical safety is not just about whether an item switches on. Damage to a plug, cable, casing or internal insulation can still present a risk.

Removing failed equipment from use is a straightforward way to protect staff, customers, tenants and visitors.
