Accurate billing and reliable data giving organisations clarity, control and confidence.
Managing water, wastewater and trade effluent charges across multiple sites can quickly become complex and resource-intensive. Variations in wholesaler tariffs, inconsistent meter reads and fragmented invoicing introduce risk, reduce visibility and make it difficult to verify whether charges are accurate. Without dependable data, organisations cannot track usage trends, challenge errors or identify inefficiencies that drive unnecessary cost.
A consolidated billing and data service provides the assurance that financial and operational decisions are based on verified, accurate information. It simplifies reconciliation for finance teams, strengthens commercial governance and helps operational teams understand where consumption is increasing, where anomalies exist and where corrective action is required. Reliable billing and data is essential for cost control, compliance confidence and long-term resilience.

We provide a single, accurate and fully validated billing solution across your entire estate. Every invoice is checked against wholesaler data, meter readings and consumption profiles to ensure you only pay for what you use. Our team resolves discrepancies directly with wholesalers, removing administrative burden and improving financial certainty.
Through detailed reporting and portfolio-wide analytics, we give you complete visibility of consumption patterns, costs and performance indicators. This insight supports better budgeting, early identification of risks and targeted efficiency activity.
Integrated with Mitie’s Plan Zero approach, we also use your data to highlight opportunities for water reduction, carbon savings and operational improvements. The result is a clear, controlled and insight-driven billing service that enhances financial accuracy and strengthens organisational resilience.
