Ensuring the electrical safety of your UK business is not just best practice – it’s the law. Whilst portable appliance testing (PAT) itself is not a legal requirement, under the Electricity at Work Regulations 1989, employers must maintain electrical equipment to prevent danger. This is where PAT testing comes in.
But how do you determine what needs testing in your unique business environment and how often? This is where a proper risk assessment is key.
At DH Electrical Services, our expert electricians don’t just conduct professional PAT testing, we can also work with you to fully assess your electrical risks and create tailored PAT testing plans.

Why Bother With a PAT Testing Risk Assessment?
Conducting a thorough risk assessment before embarking on any PAT testing has four clear benefits:
1. It meets your legal responsibilities. The Health and Safety Executive (HSE) requires you to properly evaluate workplace risks including from electrical faults.
2. It keeps you compliant. By ensuring you PAT test where necessary, you comply with regulations like PUWER that govern electrical safety.
3. It saves you money. Identifying what needs testing and when prevents over-testing and wasted expenditure.
4. It protects your business. Faulty electronics are the cause of 25% of workplace fires. And while rare, electrocutions can and do occur.
Creating Your PAT Testing Risk Assessment
While there’s no single format, the HSE provides a straightforward risk assessment framework. Here’s how it can be applied to determine your PAT testing requirements:
Step 1: Identify the Electrical Hazards
Consider the types of appliances and equipment in use along with any environmental factors that could contribute to faults. Make a list.
Step 2: Analyse the Risks
For each item, analyse associated risks considering who uses it, how often and past inspection records. Calculate overall risk levels.
Step 3: Decide on Control Measures
Using your risk analysis, determine appropriate control measures such as user checks, training or PAT testing frequencies for each appliance or area.
Step 4: Record Your Plan
Document your PAT testing plan including appliances to be tested, intervals and person responsible. Review it annually.
Using Your Findings to Implement PAT Testing
Refer to HSE guidelines on suggested initial PAT testing intervals for low through high risk appliances. For example, hand-held construction equipment should be tested every 1-3 months.
Balance testing requirements with practical factors like appliance lifespan. There’s no value in 6-monthly tests for a microwave replaced every 5 years for instance.

What this guide is based on
The standards, rules and job records behind the figures above.
- The IET Code of Practice for In-service Inspection and Testing of Electrical Equipment. What actually has to be checked on an appliance, and how often, rather than a date plucked out of the air.
- NAPIT scheme rules. What an approved contractor has to hold, record and report, including the certification we issue after every job.
- Our own job records across Liverpool and Merseyside. The figures above come from work we have actually priced and carried out, not from a national average.
