HealthExpress was the first legal online clinic to operate in the UK and first opened it doors in 2002. With a huge marketing budget many Londoners are familiar with their marketing campaigns. HealthExpress is different from other online healthcare providers because it more closely replicates the experience of seeing a doctor in the real world. Patients complete a consultation, which is reviewed by a doctor, before treatment is offered. This is a highly successful model which adds an extra element of trust for patients.
