Information about Welsh Water

Welsh Water is owned by Glas Cymru a single purpose company with no shareholders and is run solely for the benefit of customers.

The Glas Cymru business model aims to reduce Welsh Water’s asset financing cost, the water industry’s single biggest cost.

Under Glas Cymru’s ownership, Welsh Water’s assets and capital investment are financed by bonds and retained financial surpluses.

Financing efficiency savings to date have largely been used to build up reserves to insulate Welsh Water and its customers from any unexpected costs and also to improve credit quality so that Welsh Water’s cost of finance can be kept as low as possible in the years ahead.
