Overview
Water Plus is a British business water retail services provider headquartered in Stoke-on-Trent. The company was created as a 50/50 joint venture between United Utilities and Severn Trent after the Competition and Markets Authority approved the arrangement in May 2016. It received an Ofwat licence in September 2016 to provide water supply and sewerage retail services. The business was established to operate in the deregulated non-household water markets of Great Britain. England’s business water market opened to competition on 1 April 2017, allowing eligible commercial customers to choose their water and wastewater retailer rather than relying on a regional incumbent for retail services. Scotland’s business water market had already been opened to competition on 1 April 2008, providing an earlier operating environment for comparable commercial water retail activity. Water Plus focuses on business customers rather than household consumers. Its role is principally retail and customer-facing: supplying and billing commercial users for water and wastewater services, managing accounts, and supporting customers with service and consumption-related matters. The underlying physical water and sewerage networks remain associated with regional infrastructure operators, while Water Plus competes in the retail relationship with other licensed providers. The company became one of the largest business water retailers in England. The available reference material states that it employs approximately 500 people and serves more than 366,000 business customers. Those figures describe the scale reported in the source material and are not treated here as a current independently verified total. Water Plus’s corporate identity is closely linked to the two large UK water companies that established it. United Utilities operates principally in the North West of England, while Severn Trent operates across parts of central England and Wales. Their joint venture gave Water Plus access to sector expertise and a platform from which to compete nationally in the newly liberalised business market. The company’s principal strategic challenge is typical of regulated utility retail businesses: maintaining reliable customer service, managing billing and account complexity, and demonstrating value to commercial customers in a market where switching is possible. Leadership changed in 2018. Sue Amies-King, who had served as the company’s first chief executive from March 2016, was replaced by Andy Hughes, formerly of Severn Trent Water. This change represented an early transition from the company’s formation and market-launch phase to its next stage of operation. Public reference material supplied for this entry does not provide enough information to establish later leadership, ownership, financial performance, product-level branding, or a current official website with certainty.
History
Water Plus was formed during the expansion of competition in the United Kingdom’s business water sector. Its immediate corporate origins lie in a 50/50 joint venture between United Utilities and Severn Trent. The Competition and Markets Authority approved the venture in May 2016, after which the company proceeded toward regulatory authorisation and commercial operation. The business received an Ofwat licence in September 2016 covering water supply and sewerage retail services. This regulatory approval was important because Water Plus was not established as a conventional regional water infrastructure monopoly. Instead, it was designed as a retailer serving non-household customers in markets where businesses could choose among licensed suppliers. The physical delivery of water and removal of wastewater continued to depend on the wider regulated network system, while Water Plus managed the commercial relationship with its customers. Water Plus was established in preparation for the opening of England’s business water market on 1 April 2017. The reform allowed eligible commercial users in England to select their water and wastewater retailer. Scotland had opened its business water market earlier, on 1 April 2008, so Water Plus was also positioned to participate in that more mature competitive environment. Its scope therefore extended beyond the geographic territories traditionally associated with its two parent companies. The company’s headquarters are in Stoke-on-Trent. Reference material describes a workforce of about 500 employees and a customer base exceeding 366,000 businesses, making Water Plus the largest business water retailer in England at the time described. These figures indicate a substantial national retail operation, although the supplied sources do not establish the date or continuing accuracy of each figure. Leadership during the formation and launch period was provided by Sue Amies-King, who became the company’s first chief executive in March 2016. In June 2018, Water Plus announced that Andy Hughes would replace her. Hughes had previously worked for Severn Trent Water, linking the new leadership to one of the venture’s founding shareholders and to established expertise in the water sector. The available reference material provides limited detail about later developments, financial results, consumer or regulatory disputes, product innovations, and subsequent corporate ownership. Accordingly, the documented history is strongest for the company’s creation, regulatory licensing, entry into competitive business water markets, operating scale, and early leadership transition.
