Allwyn prepares for imminent UK National Lottery software upgrade

 

Allwyn is making final preparations for its UK National Lottery systems to be updated next weekend.

The company said that on Monday, August 4, around 8,000 retailers will switch over to Wave terminals.

Other retailers will use Allwyn’s updated lottery software on existing equipment until they receive a Wave terminal.

Allwyn said a “small proportion” of legacy in-store terminals “may experience delays” returning to normal operation on August 4.

Allwyn’s director of operations, Jenny Blogg, said: “These critical tech upgrades follow on from our continuous progress in modernising The National Lottery, which hasn’t had a major refresh since 2009.

“This includes introducing a fresh new look in our 43,500 retail partners with new stands, dispensers and signage, as well as rolling out state-of-the-art lottery terminals and a new in-store network provided by Vodafone.”

The software update means National Lottery services will become unavailable from 11pm on Saturday, August 2 until “late Monday morning” on August 4.

After the Lotto and Thunderball draws on August 2, the National Lottery website/app and retail lottery terminals will shut down at 11pm. Players will be unable to log into online accounts, buy tickets or claim prizes.

However, Allwyn said players will still be able to check results and buy scratchcards until the shutdown.

“While these significant updates will mean short-term disruption for players and our retail partners, they will allow us to deliver on our promise to bring new, exciting games to The National Lottery; a better player experience; and our commitment to double returns to Good Causes from £30m to £60m every week by the end of the 10-year licence,” Blogg added.
