Ascendancy Water has announced it will become the billing software provider for Castle Waters customers, after it successfully completed MOSL’s market entry acceptance testing.

Equivalent testing on Ascendancy’s Edge software has already been completed with the Central Market Agency – MOSL’s equivalent in Scotland – to allow the company to bill Castle’s existing Scottish customers.

The consultancy and software provider, which focuses entirely on the competitive water market, started billing all Portsmouth region non-household customers earlier this year. It will soon start billing for all Thames region business customers as well.

Ascendancy provides billing and pricing software for a number of retailers in Scotland. The new version of its software has now been proven to integrate with both English and Scottish markets, allowing for customers to be provided with consolidated billing across the Anglo-Scottish area.

Ascendancy Water managing director Charles Vincent said: “We are really proud to have successfully completed market entry testing with our Edge product.

“A huge amount of work has gone into developing a billing solution for Castle that is specific to the water industry and overcomes some of the historical billing issues that customers have experienced in the past.”
