Water Companies

Built for water companies. Designed around your outcomes.

SMS Water helps UK water companies deliver complex, data-led infrastructure with greater certainty. We bring programme design, leadership, technology, funding, delivery and long-term operational support together through one accountable model — all shaped around the outcomes your company needs to achieve.

Designed for the realities of water

Water companies are being tasked with delivering more than ever before.

Reduction in leakages, demand management, improved customer outcomes, strengthened resilience and meeting growing environmental expectations have all been added to their list.

At the same time, programmes must operate within regulated price controls, fixed Asset Management Plan (AMP) period capital envelopes, constrained borrowing capacity and an intense scrutiny of their performance.

These are not isolated challenges. Capital decisions affect mobilisation. Performance for years afterwards is shaped by technology decisions. Delivery choices influence operational adoption, customer experience and regulatory outcomes. When those decisions are managed in silos, they are inevitably followed by complexity, delay and avoidable risk.

SMS Water is designed to specifically address this reality. We work alongside water companies to integrate the commercial, technical, operational and delivery decisions that determines the success of infrastructure programmes.

A partner that understands the definition of success

For water companies, success is not simply the installation of assets or reaching a rollout milestone. Instead, it is defined by long-term performance, operational insight and the creation of reliable data that supports regulated, customer and environmental outcomes across AMP8, AMP9 and beyond.

That is why we design programmes starting with the outcome. We align governance, capital structure, technology, supply chain, customer engagement, data and operations from the start, which reduces interfaces and creates a single, clear line of accountability:

SMS Water brings you:

·  Delivery certainty, with governance and performance management built in from mobilisation

·  Capital productivity, with delivery structured around the investment approach and regulatory context

·  Operational value, by turning trusted data into action rather than treating installation as the finish line

·  Long-term adaptability, so that technology, partners and scope can evolve as requirements change

·  Clear accountability, through an integrated model that is led by one delivery partner

Built around your programme, not a predetermined product

Every water company has a different estate, operating environment, investment position and set of performance commitments. That’s why SMS Water’s process does not begin with a fixed technology or supplier answer.

We begin with the specific outcomes, constraints and capabilities that matter to you. We then shape the right commercial and delivery structure, coordinate specialist partners and retain the flexibility, so the programme can be adapted over time.

Proven in partnership with Southern Water

Southern Water appointed our business in 2025 as prime contractor for its smart water meter upgrade programme, covering one million meter replacements over five years.

Delivered through an Alliance with Southern Water, SUEZ and M Group Water, the programme shows how the principles behind SMS Water work in practice. Funding, programme leadership, technology, installation, connectivity, data and long-term performance are all brought together within one accountable delivery ecosystem.

This is more than a deployment programme. It is designed to generate trusted operational insight that supports earlier leak detection, improved demand management, more accurate billing, customer engagement and long-term network resilience.

Southern Water: contract award

Southern Water appointed SMS to lead an industry-leading programme to replace one million water meters over five years.

Southern Water: delivery case study

See how the Alliance delivered more than 150,000 live smart meters within eight months of mobilisation, with published evidence of delivery pace, connectivity and operational insight.
