Bosses at six water firms had £4m in bonuses blocked under new rules, Ofwat says

Regulator also considers forcing companies to report pay received from parent firms after Guardian investigation

Water company bosses were blocked from receiving 4m in bonuses for the last financial year - and the industry regulator is considering forcing companies to report pay received from parent companies after a Guardian investigation.

Ofwat, the regulator for English and Welsh water firms, said six companies had complied with the new rules governing the sector and did not pay out bonuses to bosses. However, it is consulting on further rules to force the disclosure of payments by other companies after the revelation that Yorkshire Water's chief executive, Nicola Shaw, had received 1.3m in secret payments via an offshore parent company.
