In the unlikely event that you remain dissatisfied, you may refer your complaint to the regulator of The National Lottery, or The National Lottery’s alternative dispute resolution provider, as outlined below:

Alternative dispute resolution (ADR)

This provides an independent and impartial review of transaction related disputes that remain unresolved after our complaints process is complete. For The National Lottery, alternative dispute resolution is provided by the Centre for Effective Dispute Resolution (CEDR).

A dispute can only be referred to CEDR for review if it relates to a Player’s claim of financial entitlement as a result of participation in one of The National Lottery’s constituent lotteries. The dispute must have already concluded our complaints process and received a ‘Senior Manager Response’ as a result.

You have up to 12 months from concluding our complaints process within which to refer your dispute to CEDR. We ensure that this is free of charge for National Lottery players.

Any decision made by CEDR will be informed by the relevant Games Rules, Procedures, and/or Account Terms. CEDR cannot review service related complaints regarding how the National Lottery is operated or our licensing requirements. Full information regarding the service CEDR provide can be found at

Please note that once you have made an application to CEDR, we will not be able to enter into any further correspondence with you in respect of your dispute.
