Commercial PAT testing covers the inspection and testing of portable electrical appliances in business premises. Whether you run a small shop, a large office, or an industrial facility, understanding your obligations around electrical safety is essential for compliance, insurance, and the safety of your employees and visitors.
Your Legal Obligations as an Employer
The Electricity at Work Regulations 1989 require that all electrical systems and portable equipment in the workplace are maintained in a safe condition. The Management of Health and Safety at Work Regulations 1999 require employers to assess risks and implement control measures. PAT testing is the recognised method of maintaining and demonstrating the safety of portable electrical appliances in a commercial setting.

Planning Your Commercial PAT Testing
The key to successful commercial PAT testing is good planning. Start by taking an inventory of all portable electrical appliances in your premises. Work with your PAT testing provider to schedule testing at a time that minimises disruption — before business hours, during lunch, or over a weekend. Inform your staff in advance so they know what to expect.
What Happens During a Commercial PAT Test Visit?
Our certified engineers arrive at your premises and systematically work through each area, testing every portable electrical appliance they encounter. Each appliance receives a visual inspection first, followed by electrical testing where appropriate. Appliances receive a colour-coded pass or fail label showing the test date and the next retest date. The entire process typically takes 1–3 hours for a standard office, depending on the number of appliances.
Certificates and Documentation
After testing, you receive a comprehensive test report listing every appliance tested, its test results, and any recommendations. This documentation is essential for insurance purposes, HSE inspections, and demonstrating compliance. MES PAT Testing Ltd provides digital certificates emailed to you the same day, with secure online storage for easy retrieval.
Insurance Implications
Many commercial insurance policies now require evidence of regular PAT testing. If an electrical fire or injury occurs and you cannot demonstrate that appliances were regularly tested, your insurer may reject your claim or reduce your payout. Regular PAT testing with proper documentation protects your business's insurance position.
