If you run a business, you’ve probably heard of PAT Testing. But there’s a newer, broader term you should be aware of: Electrical Equipment Testing (EET).
EET is a more modern term that includes Portable Appliance Testing and covers a wider range of equipment. It’s essential for workplace safety and required by law.
In this guide, we’ll explain what EET involves, why it matters, and which UK standards and regulations apply. We’ve also included useful links for reference — perfect for compliance officers, landlords, or business owners needing a quick resource.
What is Electrical Equipment Testing (EET)?
Electrical Equipment Testing (EET) is the inspection and testing of electrical items to ensure they’re safe to use. It includes both visual checks and electrical measurements. The aim is to prevent electric shock, fire, or equipment failure.
The testing can be applied to:
Portable appliances (e.g. kettles, laptops)
Fixed equipment (e.g. hand dryers, integrated cookers)
Extension leads and adaptors
While "PAT Testing" traditionally focuses on portable items, EET refers to the broader responsibility of testing all electrical devices in a workplace.
Legal Requirements for EET in the UK
UK law requires that all electrical equipment used in the workplace is safe. While no law directly mentions "PAT Testing" or "EET", several key regulations create the duty to test:
This is the main law requiring that electrical systems are maintained in a condition that prevents danger. Regulation 4 specifically covers system safety and maintenance.
Employers must ensure the safety of employees and the public. Regular testing of equipment is one way to meet this duty.
PUWER states that work equipment must be suitable for use and properly maintained.
Relevant Standards for EET
When conducting EET, engineers should follow British Standards to ensure best practice. Here are the most relevant ones:
BS 7671 – IET Wiring Regulations
Also known as the 18th Edition, this standard governs how electrical installations should be designed and tested.
IET Code of Practice for In-service Inspection and Testing of Electrical Equipment
Often used as the guide for EET. It outlines how often equipment should be tested, and what tests to perform.
BS EN 50699:2020
Covers the maintenance and retesting of in-service equipment.
BS EN 61010-1
Relates to the safety of test equipment used during EET.
Why Your Liverpool Business Needs EET
Failure to test equipment can result in serious accidents, legal action, or invalidated insurance. Businesses in Liverpool can’t afford to ignore this.
Here’s why EET matters:
Protects people from electrical shock and fire.
Ensures compliance with national safety laws.
Satisfies insurers that you’re mitigating risks.
Reduces downtime from equipment failure.
Improves audit readiness, especially in regulated industries.
How Often Should Equipment Be Tested?
There’s no fixed legal frequency, but the IET Code of Practice provides guidance:
Office equipment (low-risk): every 1–4 years depending on item type.
Construction sites (high-risk): every 3 months.
Hotels and schools: annually for most items.
The frequency depends on:
Type of equipment
Environment it's used in
How often it's moved or used
