There is no UK law that specifically says businesses must carry out PAT Testing.

What the law requires is that electrical equipment is maintained in a safe condition.

The main legislation is:

Health and Safety Executive Guidance

The HSE states that PAT testing is one way of helping demonstrate compliance, but it is not a legal requirement in itself.

Electricity at Work Regulations 1989

The key regulation is Regulation 4(2):

Electrical systems shall be maintained so as to prevent danger.

This is the legislation most commonly cited.

Health and Safety at Work etc. Act 1974

Employers have a duty to protect employees and others from risks, including electrical risks.

What PAT Testing Helps Demonstrate

PAT Testing provides evidence that you are:

• Inspecting equipment
• Identifying faults
• Taking reasonable steps to maintain safety
• Managing risk

This can be very useful if:

• an accident occurs,
• an insurance claim arises,
• or the HSE investigates an incident.

PAT Testing covers equipment such as:

💻 Computers and monitors

🖨️ Printers

🔌 Chargers and power supplies

☕ Kitchen appliances

📱 Office equipment
