Lizzie founded Pupils Profit in 2014, initially combining enterprise education with a healthy school tuck shop model. The aim was to help children develop transferable skills and aspirations, while also encouraging their peers to make healthier food choices. Just before the COVID-19 lockdowns, Lizzie saw an opportunity to adapt the tuck shop into a school-based refill shop, helping families reduce single-use plastic while removing the barrier of convenience for busy parents.

With seed funding from Designing London’s Recovery Green New Deal, Lizzie piloted the concept in 12 London schools. Her work caught the attention of ReLondon’s Heston in the Loop project, and a collaborating began with several London borough councils. Additional funding allowed Pupils Profit to expand the model to schools outside of London, and it is now accessible to schools across the UK.

In September 2024, Pupils Profit successfully entered the EdTech space with the launch of its platform, ecorefillshop.com. Today, Pupils Profit supports more children than ever before, empowering them to develop real-world skills while making it easier for their communities to refill via their school refill shops.
