Not really the water company's responsibility. Use of water main for main earth hasn't been allowed in the UK for very many years (one reference I've seen says 1966). Equipotential bonding is on the customer side of the main stop valve to ensure that there is no potential difference between electrical earth and water pipes. Customer is responsible for providing earth (TT, aka earth rod) if the leccy company doesn't fit a main earth terminal (TNS, TNC-S = PME)
