A missing label on a kettle is easy to overlook. A missing testing record for equipment used across several floors, departments or sites is harder to explain when an incident, audit or insurer asks for evidence. To manage PAT labels properly, businesses need a clear system that connects each label to an accurate record, a sensible retest programme and the item itself.
PAT labels are useful visual indicators, but they are not the compliance system on their own. Their value lies in helping staff identify equipment, understand its status and remove uncertainty during day-to-day use. When labels, records and site procedures agree, facilities teams can show that electrical equipment is being maintained in a safe condition without creating unnecessary disruption for staff.
What PAT labels should tell your team
A PAT label should provide enough information for a member of staff, manager or visiting engineer to identify the appliance and check its current status. Most labels show whether an item has passed or failed, the test date, the next review or retest date, and an asset or appliance reference number. Some also include the tester’s initials or company details.
The asset reference is particularly valuable on larger premises. A label that says only “Passed” may reassure somebody at the point of use, but it does not help a facilities manager find the corresponding result in a report containing hundreds of appliances. A unique reference links the physical item to its inspection and test history, location and observations.
Labels should be legible, securely attached and positioned where they can be seen without affecting safe operation. They should not cover ventilation slots, safety warnings, controls or manufacturer information. On equipment that gets hot, is frequently cleaned, is used outdoors or has an uneven surface, a conventional adhesive label may not last. In those cases, the appliance record, asset tag, cable marker or an alternative identification method may be more appropriate.
Labels support compliance, but they are not a legal certificate
Duty holders have responsibilities under the Electricity at Work Regulations 1989 to maintain electrical systems so far as is reasonably practicable to prevent danger. There is no general legal requirement to PAT test every appliance at a fixed annual interval, and there is no legal requirement for every item to carry a PAT label.
That distinction matters. A green label does not prove that an appliance is safe forever, while the absence of a label does not automatically mean it is unsafe. What matters is whether your organisation has a proportionate process for checking, maintaining and controlling electrical equipment, based on the environment and the way it is used.
Formal visual inspections, combined inspection and testing where appropriate, user checks and competent record keeping all form part of that process. PAT labels make the process visible, but they should never replace action when an item looks damaged. A frayed lead, cracked plug, loose casing or signs of overheating must be reported and removed from service, regardless of the date shown on a label.
How to manage PAT labels without losing control of your asset register
The simplest approach is to treat labels as a field tool and the test record as the source of truth. Before testing begins, decide how appliances will be identified, where results will be recorded and who will deal with failed items. This preparation avoids duplicate references, untraceable equipment and confusion once engineers are working around a busy site.
Start with a consistent numbering system
Each testable appliance should have a unique identifier. For a single office, a sequential number may be sufficient. For schools, care settings, multi-tenant buildings or organisations with several locations, a structured reference is usually easier to manage. It might identify the site, floor or department before the individual item number.
The system does not need to be complicated. It does need to be applied consistently. If an item is moved from reception to a meeting room, its unique reference should remain the same while its recorded location is updated. Reusing numbers for replacement items creates an unreliable history and can make failed equipment appear to have passed.
Record the detail that a label cannot carry
Your PAT report should include the asset number, appliance description, make or model where useful, location, test result, date, observations and next recommended inspection or test date. It should also identify appliances that were unavailable, inaccessible or not presented for testing.
This last point is often missed. An incomplete visit is not necessarily poor service – equipment may be in use, locked away, off site or unavailable because staff cannot interrupt critical work. However, those exceptions need to be recorded and followed up. Otherwise, a label programme can give a false impression that the whole premises has been covered.
Keep reports in a location that the responsible person can access after the engineer has left. A shared compliance folder or facilities management system is usually more reliable than a single employee’s inbox. Consider who will need the information during an audit, after a staff change or following an incident.
Apply labels at the point of testing
Labels should be applied, updated or removed as part of the testing activity, not added later from memory. This helps prevent a pass label being attached to the wrong item, particularly where several identical monitors, extension leads or chargers are located together.
For failed equipment, the priority is clear identification and control. The item should be marked as failed or taken out of service, and staff should know not to reconnect or use it. Depending on your arrangements, it may be isolated for repair, disposed of or replaced. Once repaired, it should be reassessed before returning to use.
Set review periods according to risk
A blanket annual retest can be convenient to schedule, but it is not always the most proportionate approach. Equipment used daily in a workshop, kitchen, school practical area or public-facing setting may justify more frequent checks than a double-insulated desk lamp in a low-risk office. Hand-held appliances and extension leads also tend to receive more wear than fixed, lightly used equipment.
Your inspection frequency should consider the environment, equipment class, user behaviour, previous faults, mobility of the appliance and manufacturer guidance. Higher-risk sites may need a closer programme, while low-risk office equipment may be managed through regular user checks and less frequent formal inspections. A competent PAT provider can help establish intervals that are defensible and practical for your premises.
Common label problems and how to deal with them
Labels fade, peel, get painted over or disappear when equipment is replaced. The answer is not always to retest immediately. First, check the asset record against the appliance’s serial number, make, model and location. If the item can be confidently identified and remains within its planned review period, a replacement label may be appropriate.
Where identification cannot be confirmed, treat the appliance as unverified. It should be inspected and, where required, tested before being relied upon. Guessing based on a similar-looking item is a poor control, especially when appliances have moved between rooms or departments.
New equipment also needs a clear process. Brand-new, reputable equipment will not usually require a full PAT test before first use, but it should be visually checked, entered onto the asset register and given an appropriate future review date. Second-hand, donated or staff-supplied equipment requires greater caution because its condition and history may be unknown.
For hired equipment, establish responsibility before it arrives on site. The hire company may provide evidence of maintenance, but the duty holder still needs assurance that the equipment is suitable and safe in the intended environment. Keep any relevant documentation with your site records.
Make labels useful for the people who use the building
Staff do not need a technical briefing on every test result, but they should understand the basics. They should know that a pass label is not permission to ignore visible damage, that failed items must not be used, and that personal or newly purchased electrical equipment should be declared before being brought into service.
Facilities teams can reduce avoidable problems by agreeing testing dates with department leads, identifying critical equipment in advance and arranging access to locked rooms, cupboards and server areas. Testing around care routines, teaching, customer appointments or manufacturing activity requires planning. A site-specific plan protects both safety standards and normal operations.
Where premises are large or operate extended hours, a phased programme may be preferable to a single intensive visit. It takes longer to coordinate, but it can reduce disruption and improve access to equipment that would otherwise be missed. The right approach depends on the type of site, the number of appliances and how easily equipment can be taken out of use.
When to ask for professional support to manage PAT labels
Outsourced support is particularly useful when an organisation has multiple sites, a high turnover of equipment, unclear historical records or a large number of appliances in varied environments. A qualified engineer can test equipment, apply and reconcile labels, identify failed items and provide records that are easier to manage at the next review.
Before booking, provide an estimated appliance count, site locations, access restrictions and any equipment that cannot be switched off during normal hours. This allows the work to be planned safely and helps avoid surprises on the day. A pre-job discussion and, where needed, a site survey can make a significant difference to the quality and efficiency of the visit.
Clear labels are helpful. Reliable records, sensible inspection intervals and prompt action on faults are what give them meaning. If your current labels no longer match your equipment or reports, addressing the gaps now is a practical way to strengthen electrical safety before they become an operational problem.
