Professional PAT Testing Services

What Is PAT Testing and Why Does Your Business Need It?

Portable Appliance Testing — commonly known as PAT testing — is the process of systematically inspecting and testing portable electrical equipment to ensure it is safe for continued use. In Scotland, the Electricity at Work Regulations 1989 place a legal duty on employers and duty holders to maintain all electrical equipment in a safe condition. PAT testing is the recognised, industry-standard method of demonstrating compliance with these regulations.

At Arnold Pat Testing, we go beyond basic compliance. Using professional multi-parameter testing equipment — one of the most advanced portable appliance testers available in the UK — we deliver comprehensive testing that provides genuinely reliable results. Every appliance receives earth continuity testing at both 200mA and 25A, insulation resistance testing at 500V DC, earth leakage measurement, touch current measurement, lead polarity testing, and where applicable, RCD trip testing.

Why Professional-Grade Equipment Matters

Not all PAT testers are equal. Basic pass/fail testers — the kind some budget providers use — simply cannot deliver the accuracy, range of tests, or data management capabilities of a professional multi-parameter tester. When we tell you an appliance has passed, you can trust that result absolutely. When we recommend removal, there is a genuine, documented reason.

Our digital measurement systems deliver reliable, repeatable results across thousands of tests. Automated test sequences select the appropriate tests for each appliance class without manual intervention, reducing testing time while maintaining comprehensive coverage. Every test result is digitally logged with the appliance identification, test parameters, pass/fail status, and date — creating a complete digital audit trail for your compliance records. For full technical transparency, our primary instrument is the industry-trusted Seaward Apollo 500.

Our Testing Process

Every PAT testing visit from Arnold Pat Testing follows a structured, professional process. We begin with a thorough visual inspection of each appliance — checking for damage to cables, plugs, and casings; verifying correct fusing; and identifying any obvious safety concerns. According to the IET Code of Practice, visual inspection alone can identify up to 90% of electrical faults.

Following visual inspection, we connect each appliance to a professional multi-parameter tester for comprehensive electrical testing. The automated test sequences run the full suite of appropriate tests for each appliance class — Class I, Class II, and IT equipment are all tested to the correct parameters without manual configuration.

Every tested appliance receives a durable pass or fail label showing the test date, next test date, and our identification. You receive a comprehensive digital report listing every appliance tested, its unique identifier, all test results, and pass/fail status. This report serves as your documented proof of compliance for insurance audits, HSE inspections, and local authority checks.

Competitive, Transparent Pricing

We provide clear, written quotes based on your specific requirements — the number and type of appliances, your location, and any access considerations. There are no hidden charges, no pressure to condemn equipment unnecessarily, and no commissions on replacement sales. We are completely independent: we test, report, and advise.

Whether you're a small Edinburgh office with 30 appliances or a multi-site Glasgow operation with thousands, we can schedule your PAT testing at a time that minimises disruption to your business.
