Trosolwg

Under Article 15 of the UK GDPR, you have the right to obtain confirmation of whether an organisation is processing your personal data and, if so, to receive a copy of that data. This is known as a Subject Access Request (SAR) or Data Subject Access Request (DSAR). Organisations must respond within one calendar month. The request is free.

Identify the Organisation

Determine which organisation holds your data. This could be your employer, bank, GP, school, social media platform, or any organisation that processes your personal data.

2

Write Your Request

Send a written request (email or letter) asking for a copy of all personal data held about you. You do not need to use any specific form or mention the UK GDPR, but it helps to be clear. Include enough information to identify yourself (name, account number, etc.).
