Why Understanding PAT Testing Frequency Matters
If you own or manage a business, rental property, or public space in London, PAT testing isn’t just a best practice — it’s a smart risk management move.
Not testing regularly can increase the chance of electrical accidents, which could result in liability claims, failed inspections, or worse. That’s why understanding pat testing frequency is essential.
Factors That Affect PAT Testing Frequency
Appliance Type
Different appliances carry different risks. Handheld tools and portable heaters require more frequent testing than stationary or rarely moved items.
- High-risk: Kettles, extension leads, power tools – test every 6-12 months
- Medium-risk: Desktop computers, microwaves – test every 1-2 years
- Low-risk: Fixed equipment like built-in fridges – test every 2-4 years
Environment of Use
PAT testing frequency varies based on the environment.
- Construction sites: every 3 months
- Schools, offices: every 12-24 months
- Rental properties: every change of tenant or annually
At Budget PAT Testing, we tailor your testing schedule based on risk level and usage type.
Legal Guidelines on PAT Testing in the UK
UK legislation doesn’t provide a fixed schedule for PAT testing, but under the Electricity at Work Regulations 1989, all electrical devices must be kept in safe working condition through proper maintenance.
The HSE advises using a risk-based approach when planning your inspection and testing intervals.
How Often Should Landlords and Employers Test?
Landlords and employers must maintain a documented record of inspections.
- Landlords: Test all portable appliances at least once a year, especially before new tenants move in.
- Employers: Set a testing interval based on the type of workplace and equipment usage.
Budget PAT Testing helps with legally compliant logs and reports for any inspections or claims.
PAT Testing Frequency: DIY or Professional?
While you can perform visual inspections yourself, using a certified technician ensures detailed testing and documentation.
- DIY: Useful for quick checks but lacks legal weight
- Professional: Detailed testing, certified logs, and peace of mind
Budget PAT Testing offers quick, reliable service that meets UK compliance standards.
