Water and sewerage regulator Ofwat has finalised its first-ever external legal panel, appointing three firms to the roster.

Addleshaw Goddard, Norton Rose and Wragge & Co have all won spots on the panel, with the trio appointed following a tender process that kicked off in November last year.

The panel appointments, which will run for four years from 1 March, will see the three firms work closely with the body's own in-house legal team.
