Retail deregulation: value-chain strategy for a major water utility
ENERGY AND UTILITIES · STRATEGY · OPERATING MODEL
The situation
TA regulated water utility with about a sixteen per cent share of a national market faced retail deregulation: the regulator was lowering the threshold for competition, replacing a single price with separate wholesale and retail controls, and shifting the competitive measure from asset ownership to operating efficiency. Built for a geographic monopoly, the utility lacked commercial sales, modern metering, and flexible service, and its retail cost to serve sat well above the industry curve, exposing it to lower-cost entrants.
The work
We built a commercial roadmap across segmentation, capability gaps, and three board-level structural options.
Segmented the commercial base into five tiers, from large industrial through multi-site to small business, sized by accounts and revenue, and ran face-to-face research with major buyers to set a service baseline.
Engineered three options for the board: grow retail and use scale to compress unit cost; exit retail by selling the retail arms; or retain the back office and provide outsourced servicing to competing retailers.
Benchmarked cost to serve against industry leaders, isolating a roughly £18.8 million household and £4.7 million non-household savings pool, against a target to cut retail cost to serve by about nine per cent, or £12.1 million.
Set a four-pillar delivery programme across channels and self-service, end-to-end process, financial analytics, and a single customer billing view.
The outcome
A clear framework for the board to weigh growth, divestment, or an outsourcing pivot on long-term asset returns.
Customer-retention models, including consumption-reduction offers, to blunt price competition from new entrants.
A quantified path to bring retail cost to serve toward best-in-class.
