The National Lottery is set to pause sales and prize claims for about 36 hours starting at 11 PM on Saturday, August 2, 2025, to facilitate a significant technology upgrade, marking the most substantial change in its 31-year history.

Approximately 8,000 retailers will receive new Wave terminals to improve transaction speed and functionality, while others will update their existing terminals with new software.

Allwyn, the operator of The National Lottery, is preparing for this upgrade by conducting testing and providing retailers with guidance and support materials to ensure a smooth transition.

Allwyn has expressed gratitude to its 43,500 retail partners for their support during this significant technology upgrade scheduled from August 2-4, 2025.

Jenny Blogg, Allwyn's director of operations, noted that the last major refresh occurred in 2009, highlighting the necessity for modernization.

Importantly, the EuroMillions draw on Friday, August 1, 2025, will proceed as scheduled, allowing players to participate in the potential jackpot.

Post-upgrade, winners will need to complete an online claim form and upload a photo of their winning ticket to claim their prizes.

Retailers are advised to keep their terminals powered on, maintain sufficient Scratchcard stock, and prepare for a new sign-on process beginning on August 4.

Despite facing delays due to legal challenges from the previous operator, International Games Technology (IGT), Allwyn remains focused on its long-term goals, including doubling funds for good causes.

Although the transition has impacted the launch of new draw-based games and early financial targets, Allwyn is committed to enhancing player experience and increasing contributions to good causes.

During this downtime, players can still check results and purchase Scratchcards, with draw results available on the National Lottery’s YouTube channel.

This upgrade will bring several enhancements, including a refreshed design for The National Lottery in over 43,500 shops, direct payment of retail prizes into players' bank accounts, and new participation methods like home delivery and Aldi self-checkouts.
