PAT Testing Cardiff
Portable Appliance Testing for Businesses, Landlords and Events
Portable Appliance Testing (PAT) is essential for demonstrating that your electrical equipment is safe to use. Our PAT testing service covers all classes of portable appliances for businesses, landlords, schools, care homes, and events across Cardiff and South Wales. Every item is tested, labelled, and recorded on a detailed asset register.
Professional PAT Testing Service
While PAT testing is not a specific legal requirement, the Electricity at Work Regulations 1989 require that all electrical equipment be maintained in a safe condition. PAT testing is the most common and effective way businesses and landlords demonstrate compliance. Our service goes beyond basic pass/fail testing — we inspect each item thoroughly, test according to its class and risk level, and provide actionable recommendations.
We test Class I appliances (earthed equipment like kettles, computers, and printers), Class II appliances (double-insulated equipment like phone chargers and lamps), and Class III appliances (extra-low voltage equipment like laptop power supplies). Each class requires different test sequences using calibrated PAT testers that check earth continuity, insulation resistance, polarity, and functional operation.
For businesses, we work around your schedule to minimise disruption. For landlords, we coordinate with tenants for access. For events, we provide pre-event testing with rapid turnaround. Every tested item receives a pass or fail label, and you receive a comprehensive asset register showing test dates, results, next-test due dates, and any recommended actions.

What Happens If You Delay PAT Testing Cardiff?
Ignoring electrical issues is one of the most common — and dangerous — decisions property owners make. Here's what you risk by waiting.
Electric Shock to Staff
Untested appliances with damaged cables or failed insulation create shock hazards in the workplace.
Equipment Fire
Defective appliances with internal faults can overheat and ignite, particularly in offices with paper and furnishings.
Insurance Claim Rejection
If an untested appliance causes damage or injury, insurers may reject claims for lack of maintenance records.
HSE Enforcement
The Health and Safety Executive can prosecute employers who fail to maintain electrical equipment in safe condition.
Tenant Liability
Landlords providing appliances in rental properties have a duty of care. Untested equipment exposes you to personal injury claims.
Event Cancellation
Many venues and insurers require pre-event PAT certification. Missing documentation can force event cancellation.

PAT Testing Cardiff — In-Depth Technical Guide for Cardiff Properties
PAT Test Classes and Methods
Class I appliances rely on earthing for protection. Our PAT testers measure earth continuity (must be below 0.05Ω plus lead resistance) and insulation resistance (must be above 1 MΩ). Class II appliances have double insulation with no earth connection. We test insulation resistance at 500V DC, looking for readings above 2 MΩ. Class III appliances operate at extra-low voltage (below 50V AC or 120V DC) and are tested for polarity and functional operation. Each class requires different test voltages, pass thresholds, and inspection criteria.
Test Frequency Guidance
PAT testing frequency depends on equipment type, usage environment, and risk level. Construction site power tools need testing every 3 months. Office equipment typically needs annual testing. Hotel room appliances benefit from annual testing. Care home equipment requires 6-monthly testing due to vulnerable users. We assess your specific situation and recommend appropriate test intervals that balance safety and cost. For contract customers, we automatically schedule tests when due.
Calibrated Equipment and Traceability
All our PAT testers are calibrated annually by UKAS-accredited laboratories with certificates traceable to national standards. This ensures test results are legally defensible and accepted by insurers, HSE inspectors, and local authorities. We maintain calibration records for all equipment and can provide certificates on request. Test results are stored securely with full backup, ensuring your records are never lost.
