The Water Industry (Charges) (Vulnerable Groups) Regulations 1999 apply for metered customers who meet certain criteria to protect them from paying large water bills.
Ofwat, the economic regulator of the water and sewerage industry in England and Wales, collects data on the number of households receiving assistance under the Vulnerable Groups Regulations in the water companies’ annual June returns. The latest figures on the number of households that have been granted assistance in paying their water bills are from 2005-06 and are reported by water company rather than local authority area, and are set out in the following table.
Water company Number of households Anglian 719 Dwr Cymru 426 Northumbrian (North East and Essex and Suffolk) 672 Severn Trent 1,223 South West 2,962 Southern 324 Thames 1,780 United Utilities 1,447 Wessex 622 Yorkshire 1,308 Bournemouth and W Hampshire 96 Bristol 391 Cambridge 97 Dee Valley 16 Folkestone and Dover 42 Mid Kent 103 Portsmouth 30 South East Water 114 South Staffordshire 139 Sutton and East Surrey 64 Tendring Hundred 328 Three Valleys 284 Total 13,187
