The Information Commission has contacted you

Receiving contact from the Commission means they are looking into your organisation's handling of personal data. This could be because of a complaint from an individual, concerns arising from a data breach you reported, or a proactive audit.

The Commission is the UK's data protection regulator. They have significant powers to investigate organisations and take enforcement action. How you respond matters.

Types of Information Commission investigation

The Commission may contact you for several reasons:

  • Complaint investigation: An individual has complained about how you handle their data
  • Breach investigation: Follow-up to a data breach you reported
  • Compulsory audit: The Commission requires you to allow them to audit your practices
  • Enforcement investigation: The Commission has identified potential serious breaches (most serious)

Immediate steps

  • Note the deadline: Commission letters specify response deadlines. Request an extension before the deadline if needed.
  • Gather documents: Collect processing records, policies, breach logs, and relevant correspondence.
  • Involve the right people: Your DPO if you have one. Consider legal advice for serious investigations.
  • Preserve records: Destroying or concealing documents is a criminal offence.

Your duty to cooperate

UK GDPR requires data controllers to cooperate with the Commission. This is not optional. The Commission has statutory powers to compel cooperation.

Information Commission powers

The Commission can:

  • Require you to provide information and documents
  • Enter and inspect your premises (with a warrant if necessary)
  • Interview staff and officers
  • Examine equipment and materials
  • Access and copy records

Consequences of non-cooperation

Failing to cooperate can result in:

  • Additional enforcement notices requiring cooperation
  • Higher penalties if non-cooperation is treated as an aggravating factor
  • Criminal prosecution for obstruction in serious cases
  • Adverse inferences drawn from your failure to explain

What the Information Commission may ask for

The Commission may request: processing records, policies, privacy notices, processor contracts, breach logs, SAR logs, consent records, DPIAs, and training records.

For audits and serious investigations, Commission officers may visit your premises and interview staff. You may have legal representation present.

Possible outcomes

After investigation, the Commission may:

  • Take no further action if there was no breach or a minor breach you addressed
  • Make recommendations without formal enforcement
  • Issue a reprimand (public record of infringement)
  • Issue an enforcement notice requiring specific compliance steps (non-compliance is criminal)
  • Issue a monetary penalty for serious infringements

Your rights during an investigation

While you must cooperate, you have procedural rights:

  • Representations: Before enforcement, the Commission must issue a notice of intent allowing you to respond
  • Appeal: You can appeal to the First-tier Tribunal within 28 days of a decision
  • Legal advice: You can seek legal advice at any stage (strongly recommended for serious cases)
  • Privilege: Communications with legal advisers may be protected, but routine business documents are not

After the investigation

Whether or not the Commission takes formal action, use the investigation as an opportunity to strengthen your data protection practices.
