How this is calculated
If you complain to a data controller about how your personal data was handled, they should give you a final response. You then have 3 months from receipt of that response to refer the matter to the Information Commissioner's Office.
If the controller fails to respond within 3 months of your initial complaint, you can also take the matter directly to the ICO at that point.
