The award-winning SHL.UK is the largest digital sexual health service in Europe.

“SHL was introduced to help local authorities to manage increased demand for sexual health testing. It has enabled us to provide more care with the precious resources that we have. The dedicated laboratory meant we could increase the service to support people with mild symptoms. Everything we asked for that was possible, was done without hesitation.”  

Adrian Kelly, Lead Commissioner Sexual Health London, City of London Corporation
