# On the Register > On the Register checks UK weight loss clinics and online pharmacies against the official regulator registers. On the Register is an independent UK directory that checks weight loss clinics and online pharmacies against the public regulator registers (CQC, GPhC, HIS and HIW). Each listing shows the registration number, the regulator and the date we checked.
