Making a Subject Access Request

You have the right to request access to your personal information, this is commonly known as a Subject Access Request.

A Subject Access Request enables you to receive a copy of the personal information we hold about you and to check that we are lawfully processing it.

You will not have to pay a fee to access your personal information. However, we’re allowed under the law to charge a reasonable fee if your request for access is manifestly unfounded or excessive. Alternatively, we can refuse to comply with the request in such circumstances.

We’ll act upon the request without undue delay and at the latest within one month of receipt. We may extend the time to respond by a further 2 months if the request is complex or we have received a number of requests from the same person.
