If your Cheshire business uses portable electrical equipment — computers, monitors, kettles, extension leads, power tools, heaters, printers, chargers — then you have a legal duty to ensure those items are safe. That's where PAT testing comes in. This guide explains what it is, who needs it, and how often you need to do it.
What is PAT Testing?
PAT stands for Portable Appliance Testing. It's a process that checks the electrical safety of any portable equipment used in a workplace. The test involves a visual inspection for damage, a check of the plug and cable, and electronic testing using a PAT testing machine to confirm insulation resistance and earth continuity. Each item that passes receives a "Tested" sticker with the date and next test due.
Under the Electricity at Work Regulations 1989, employers and landlords have a legal responsibility to maintain electrical equipment in a safe condition. PAT testing is the most common method of meeting that obligation. Our PAT testing services cover all types of businesses across Cheshire — from small offices to large industrial units.
Which Businesses Need PAT Testing?
Any business that uses portable electrical equipment needs regular PAT testing. This includes:
- Offices, retail premises, warehouses
- Rental properties with provided appliances (fridges, microwaves, TVs)
- Construction sites and workshops
- Hotels, restaurants, nurseries, care homes
- Schools, colleges, leisure centres
Essentially, if you have employees or members of the public using your electrical equipment, you need to prove it's regularly inspected and safe.
How Often Should PAT Testing Be Carried Out?
There's no legal mandate for a specific frequency — it depends on the type of equipment and how it's used. HSE guidance suggests:
- Construction tools: Every 3 months
- IT equipment (office): Every 2–4 years
- Portable heaters, kettles: Every 6–12 months
- Handheld equipment (power drills, etc): Every 6 months
- Rental property appliances: Every 2 years or at tenancy change
The key is to carry out a risk assessment and create a testing schedule that suits your business. Our engineers will advise on the appropriate intervals for your situation.
How Much Does PAT Testing Cost?
PAT testing is typically charged per item or by the hour depending on the scale of the job. For a small office with 30–40 items, you'd be looking at £80–£150. For larger businesses, many providers offer fixed-fee contracts where we visit annually or bi-annually and test all your equipment. All tested items receive a label, and you'll get a full test report listing every item.
PAT Testing Across Cheshire
We provide PAT testing services across the full Cheshire and Greater Manchester area. If you operate a business in south Cheshire, we regularly visit commercial premises for PAT testing in Wilmslow and PAT testing in Knutsford. We also cover the Stockport and south Manchester areas, including PAT testing in Cheadle and PAT testing in Sale.
Can I Do PAT Testing Myself?
You don't legally need a qualified electrician to carry out PAT testing — any "competent person" can do it, as long as they're trained and have the right equipment. However, most businesses prefer to use a professional service for peace of mind and comprehensive documentation. In the event of an incident or insurance claim, having certified PAT records from an external provider adds credibility.
