The trades, and who holds them

A registration carries exactly one specialty. 85 appear in the file; 68 of them have a page here.

One licence, one specialty

Unlike some registers, this one records a single specialty per registration — so these pages do not overlap, and their totals add up. A business that does two trades holds two registrations, which is why 161,230 registrations belong to 149,441 businesses.
