How often does your business need PAT testing? Complete guide to testing frequencies, legal requirements, and recommendations for every business type.
PAT testing frequency depends on your type of business, the equipment being tested, and the environment it's used in. While there's no law specifying an exact interval, the Electricity at Work Regulations 1989 requires you to maintain electrical equipment to prevent danger. The Health and Safety Executive (HSE) recommends a risk-based approach.
The key factors that determine how often you need PAT testing are:
Here are the recommended PAT testing frequencies for different types of businesses in the UK:
| Business Type | Equipment Type | Recommended Frequency |
|---|---|---|
| Offices & Professional Services | IT equipment, kitchen appliances | Every 2-4 years |
| Restaurants, Cafes & Pubs | High-use kitchen equipment | Every 6-12 months |
| Retail Shops & Stores | Display equipment, general appliances | Every 1-2 years |
| Gyms & Fitness Centres | Exercise equipment, audio systems | Every 1-2 years |
| Schools, Colleges & Nurseries | Classroom equipment, IT suites | Every 1-2 years |
| Hotels, B&Bs & Guest Houses | Portable appliances in guest rooms | Every 1-2 years |
| Hair & Beauty Salons | Electrical styling equipment | Every 1-2 years |
| Construction Sites | Power tools, site equipment | Every 3 months |
| Industrial & Manufacturing | Heavy equipment, machinery | Every 6-12 months |
A PAT test certificate is typically valid for 12 months for most workplaces. However, low-risk environments like offices with mainly IT equipment may extend to 24-48 months. Your PAT tester will advise on the appropriate frequency based on your specific premises and equipment types.
It's important to note that there is no legal expiry date on a PAT certificate — the recommended retest date is based on risk assessment. However, most insurance policies and industry standards expect annual testing for most business types.
Landlords with Houses in Multiple Occupation (HMOs) are required by law to have annual PAT testing. For other rental properties, regular inspection is recommended every 1-2 years to meet your legal duty of care under the Housing Act 2004.

We'll consider your business type, equipment inventory, and operational environment.
New equipment isn't legally required to be PAT tested before first use — it comes with its own safety certification from the manufacturer. However, many businesses include new items in their testing schedule for documentation purposes. Once the item has been in use, it follows your regular testing frequency.
