About us Our funders Corporate support Jepson Jepson & Co Ltd, the oldest number plate manufacturer in the UK, have organised some very successful fundraising events for Sheffield Mind. They held a 'Tea & Talk' event, where their staff got together, chatted, drank tea, ate cake and raised awareness of mental health in the workplace. They also raised funds for us through their association with a car dealership in the West Country - and made us our very own number plate, which takes pride of place in reception!
