A green sticker on a kettle, monitor or extension lead can look like a small detail. For a facilities manager or duty holder, however, clear PAT labels for business equipment provide a visible record that electrical items have been checked, identified and brought into a managed inspection process.
A label is not a substitute for proper testing, maintenance or day-to-day visual checks. It does, though, help staff quickly understand whether equipment has been assessed, when it was tested and how it can be traced in the test records. When hundreds or thousands of appliances are spread across an office, school, care setting or managed property, that clarity matters.
What PAT labels for business equipment should show
The information shown varies according to the testing provider and the needs of the site. A clear, durable label will normally state whether an item has passed or failed, the test date, a retest or review date, and an appliance or asset identification number. Some labels also include the tester’s initials, company details or a barcode for quicker access to the corresponding record.
The asset number is particularly useful. It connects the physical appliance to the PAT report, where the full details should be held: appliance description, location, electrical class, test results, any observations and the action taken. If a member of staff reports a problem with a labelled item, the number helps the responsible person identify it without uncertainty.
Pass labels are commonly green, while failed equipment may receive a red label or a clear warning label. Colour is helpful, but the wording is more important. Staff should never be expected to rely on colour alone, especially where labels have faded, equipment is used in poor lighting, or colleagues have colour-vision deficiencies.
A label is useful evidence, not proof of compliance
Businesses sometimes assume that a current PAT label proves they have met every electrical safety obligation. That is not quite right. The legal duty is to maintain electrical equipment so that it does not create danger. PAT is one practical way to support that duty, combining user checks, formal visual inspections and electrical testing where appropriate.
A label records a point in time. It cannot show whether a cable was damaged after testing, whether a plug has been replaced incorrectly, or whether an appliance is being used in conditions it was not designed for. Staff still need to report frayed leads, cracked plugs, overheating, loose sockets and other visible signs of damage immediately.
This distinction is important during an audit, investigation or insurance query. A well-managed system includes accurate labels, detailed test records, sensible inspection intervals, prompt remedial action and clear responsibility for removing unsafe items from use. The label supports that system; it does not replace it.
Where labels should be placed
PAT labels should be visible enough to be checked without dismantling a workstation or moving heavy furniture, but they must not cover safety instructions, ventilation slots, manufacturer markings or controls. On laptops, monitors and desktop equipment, an accessible side or rear surface is often suitable. On extension leads, labels are normally placed on the lead body or plug end where they can be read easily.
Placement needs practical judgement. A label on a frequently cleaned item may need extra protection or a more suitable material. Equipment used outdoors, in kitchens, workshops or healthcare environments can need labels that tolerate moisture, cleaning products, heat and regular handling. For some small items, a numbered tag or an asset register may be more practical than a large sticker.
The aim is traceability without creating a new problem. Labels should not interfere with safe operation, cleaning routines or infection-control requirements.
Failed items need a clear process
When an appliance fails inspection or testing, it should be removed from use promptly. A failed label helps prevent someone plugging it back in, but it is not enough on its own. The item should be isolated where possible and recorded for repair, replacement or disposal.
This is where clear communication protects the business. Staff need to know that a failed label is not an inconvenience to work around. Using another extension lead or moving the appliance to a different room does not resolve an electrical fault. A simple escalation route for failed equipment keeps the response consistent across the site.
Getting dates right on PAT labels
The date displayed on a PAT label can cause avoidable confusion. Many labels show a suggested retest date, but there is no single legal rule requiring every appliance to be tested annually. Appropriate intervals depend on the type of equipment, its environment, how often it is moved or handled, who uses it and its previous condition.
For example, a desktop computer in a low-risk office may not need the same inspection frequency as a handheld tool in a maintenance area. A device used by the public, pupils, residents or patients may justify closer attention because of its use pattern and the consequences of a fault. Equipment exposed to damp, dust, impact or frequent transport also carries different risks.
A date should therefore reflect the site’s risk-based testing schedule, not a blanket assumption. If circumstances change – perhaps a room becomes a workshop, equipment is moved between sites, or an appliance is repaired – the inspection approach may need to change too.
Why consistent labelling makes site management easier
On a single small site, it may be possible to remember where key appliances are located. Across multiple floors, buildings or properties, memory is not a control measure. Consistent PAT labelling makes it easier to identify untested items, confirm assets included in a programme and spot equipment that has appeared on site without being added to the register.
It also reduces disruption during future visits. When appliances already carry clear asset numbers, engineers can work systematically, records can be updated efficiently and staff are less likely to be asked repeatedly whether an item has been tested. This is particularly valuable in schools, healthcare settings and busy offices where access must be planned around daily operations.
A well-organised label system can support wider asset management too. It can highlight duplicate equipment, old appliances nearing replacement, and items that have moved away from their recorded location. The benefit is not paperwork for its own sake. It is better visibility of equipment that people rely on every day.
Preparing your business for PAT testing
The best results come from planning before the engineer arrives. Identify the areas to be tested, agree access arrangements and let staff know what will happen to equipment during the visit. Where possible, make appliances accessible and ensure responsible contacts are available for rooms with restricted access.
It is also sensible to decide how new equipment will enter the system. A new appliance may be supplied with a manufacturer’s declaration and may not require immediate electrical testing, depending on the risk assessment. It should still be added to the asset register and subject to routine user checks. Second-hand items, donated equipment and appliances brought in by staff deserve more careful consideration before use on business premises.
A competent provider should discuss the site’s working pattern, equipment types and any higher-risk areas before testing begins. This allows labels, records and test intervals to reflect the real environment rather than a generic schedule.
Choosing labels that support reliable records
Cheap or poorly applied labels can peel away, become unreadable or leave staff unsure which record belongs to which item. For routine office equipment, a standard durable label may be sufficient. In more demanding environments, stronger materials and more detailed asset identification may be justified.
The more important question is whether the labels match the records. Each number should be unique, each result should be recorded accurately, and failed items should have a documented outcome. If a label is replaced because it is damaged or missing, the asset record should remain intact rather than creating a duplicate entry.
Janus Safety Solutions plans PAT testing around the needs of each site, helping businesses maintain clear records and minimise interruption to normal operations. Qualified engineers can identify equipment, apply suitable labels and provide the reporting needed for a practical electrical safety management process.
A label may be small, but it should make the next safe decision easier: staff can see the status of an appliance, managers can trace its record, and unsafe equipment can be taken out of service without delay.
