Data protection

Data Protection law in the UK is governed by the ‘General Data Protection Regulation’ or ‘GDPR’ (EU Regulation 2016/679) and the Data Protection Act 2018. These pieces of legislation give individuals rights and requires those who record and use personal information to be open about the information they hold.

GDPR sets out six basic principles of good information handling.


Anyone processing data must comply with the following principles, which are enforceable. The data must be:

  • processed fairly and lawfully
  • collected and processed for specified, explicit and legitimate purposes
  • adequate, relevant and not excessive
  • accurate and up-to-date
  • not kept longer than necessary in a form which permits identification of data subjects
  • kept securely and protected against unauthorised processing, loss , destruction or damage

Right to data portability
Right to object to processing
Rights regarding automated decision-making

Some of these rights may only apply in certain circumstances.

Road Traffic Collision requests

Where an incident has occurred within British Transport Police's jurisdiction, insurance companies can request third party details and copies of incident reports under the Road Traffic Act.

Information held in relation to a collision will most likely be held in an incident report, crime report or in an Officer's Pocket Note Book.

British Transport Police has a duty under Data Protection legislation to protect personal information. We must be satisfied that you have a legitimate interest in obtaining the requested information and that disclosure is necessary for that purpose.

Information will be considered on a case by case basis.

We must be satisfied that the intended use is for the purpose of, or in connection with, any legal proceedings (including prospective legal proceedings), or is necessary for the purposes of establishing, exercising or defending legal rights.
