Data protection complaints
Last updated: August 2026
If you are unhappy with how Byter Ltd has handled your personal information, this page tells you how to say so and what we will do about it.
What counts as a complaint
Any expression of dissatisfaction about how we have handled someone’s personal information. It does not have to use the word “complaint”, cite a regulation, or arrive in any particular format. Replying to one of our emails to ask how we got your address and why we are contacting you is a complaint, and we treat it as one.
How to complain
Email info@byter.com with what happened and what you would like done. If you would rather write to us: Byter Ltd, 33 Cavendish Square, London W1G 0PW.
You do not have to come to us first.You can complain to the Information Commissioner’s Office instead, or at the same time. We will never ask you to exhaust our process before going to them.
What we will do
- We acknowledge in writing within one working day.
- If it concerns marketing, we stop contacting you the same day and add you to a permanent suppression list — before we investigate anything. An objection to marketing is absolute, so there is nothing for us to weigh up and no reason to make you wait for the outcome.
- We investigate what we hold, where it came from, what our basis was, and what was sent.
- We respond in writing within one calendar month — what we found, what we did, and what happens next. If we cannot resolve it in that time we will tell you why and give you a new date before the month is up.
- Our response always tells you how to escalate to the ICO, whether or not we think we have resolved it.
Taking it to the regulator
You can complain to the Information Commissioner’s Office at any point:
