About LloydsDirect
NHS prescriptions are complicated. And we want to change that. Driven by an innovative spirit and strong moral compass, weâre on a mission to make NHS prescriptions simple for everyone.
Since 2015 weâve grown from a plucky start-up to a team of over 200 people â and become the fastest growing pharmacy in the UK. Today, over half a million people use our apps to manage their NHS prescriptions, and our patients rate us as âExcellentâ on Trustpilot.
But thereâs so much more to do. Because while 1 in 2 adults in the UK has a repeat prescription, only 3.2% of them use an online pharmacy. And we need bright minds to help us change how people manage their medicine for good.
True to our start-up roots, LloydsDirect has a supportive, entrepreneurial culture. We move fast, challenge the status quo, and always try to do the right thing. Sound good? Then weâd love to hear from you.
