About us

At Allwyn, we are dedicated to changing lives and growing the National Lottery responsibly, championing its positive impact on people, places, and the planet.

Innovation - We pride ourselves on it! We’re constantly looking for new ways to excite our customers, bringing new products to market to enjoy which is all supported by our responsible play values and making them accessible to all.

Giving back – Did you know that playing the lottery generates around £30m a week for charities and good causes in the UK? Our aim is to have doubled this number by the end of the first 10-year license.

Sustainability – Our aim is to become a net zero national lottery. We have 2030 targets to decarbonise our operations and energy. We’ve already transitioned to renewable energy providers, made our London and Watford offices zero gas, and ensured our fleet consists of low-emission vehicles. In addition, we’re working with our value chain partners to develop a net zero target date.

Empowering every voice – We believe in creating a culture where everyone feels they belong, can be themselves, has access to opportunities and can thrive for the benefit of good causes. Our diverse teams are working hard to make all parts of The National Lottery inclusive – whether people play a game in a store or online, because when everyone can play, everyone wins..
