PAT Testing in the UK: What It Is, Why It Matters, and How to Stay Compliant

Introduction

PAT testing (Portable Appliance Testing) is a vital part of maintaining electrical safety in homes, workplaces, and rental properties across the UK. While it isn’t always a legal requirement, failing to properly test and maintain your electrical equipment could lead to serious safety risks, insurance issues, or even legal consequences.

In this guide, we’ll cover everything you need to know about PAT testing in the UK — including what it is, who needs it, how often it should be done, and how much it costs.
