Complaints: 0844 220 4020

With British Telecom being one of the UK’s largest Phone Service Providers (also now broadband, video on demand etc), and being based out of London, you’d think following their complaints procedure would be pretty straight forward. This isn’t always the case however, so we’ve put together a step-by-step guide to get you through the process smoothly.


What You’ll Need

Before we show you how to make a complaint, here are a few things it’s recommended you have prepared before you do:

  • A brief description of your complaint
  • Your desired outcome
  • Relevant personal information
  • Account numbers and reference codes (these can be found on your latest bill, or previous BT paperwork)

To Complain Online
