Overview: If you are unhappy with any aspect of the National Lottery you should complain directly to Allwyn, the company which runs the National Lottery.

The National Lottery complaints process

  1. 1. Follow Allwyn’s complaint procedure

    Read the complaints information on the National Lottery’s website (opens in new tab).

  2. 2. Contact Allwyn

    You can submit your complaint by phone, email or in writing.

    By phone

    0370 737 3983

    0370 737 8249 if you're deaf or have a hearing impairment and are using Minicom equipment.

    By email

    In writing

  3. 3. Wait for the response

    Allwyn aims to respond to complaints by email within 24 hours and complaints by post within 5 working days.

    When the investigation is complete, Allwyn will tell you the result of your complaint and what happens next.

  4. 4. If you're not happy with the outcome

    If you are not satisfied with the result, you can escalate your complaint to Allwyn’s managers or senior managers.

  5. 5. If you’ve escalated your complaint and are still not happy

    If you have been through the full complaints procedure with Allwyn, you can complain to the National Lottery’s Alternative dispute resolution (ADR).

    You will need to contact the Centre for Effective Dispute Resolution (CEDR). This free service is the ADR for the National Lottery.

    Once you've referred your dispute to CEDR, Allwyn will no longer be able to speak to you about your complaint.

    Use CEDR to refer a dispute

    You have up to 12 months from finishing Allwyn’s complaints process to take your dispute to CEDR.
