The problem
Your water bill may be costing more than it should
- Incorrect meter readings
- Estimated bills
- Hidden leaks
- Continuous overnight consumption
- Incorrect tariff classification
- Duplicate charges
- Wastewater charges based on inaccurate assumptions
- Surface-water drainage charges
- Vacant-site consumption
- Unused or redundant meters
- Inefficient washrooms, kitchens & cooling systems
- Poor visibility across multiple sites
- Lack of invoice validation
- Gradual usage increases that go unnoticed

What we do
Services built around commercial water cost
Water Bill Audit
Review invoices, tariffs, meter information, wastewater charges, historical billing, and account structure.
On-Site Water Audit
Inspect water-consuming equipment, processes, meters, operational practices, and potential sources of waste.
Leak & Abnormal Usage Investigation
Analyse consumption patterns and investigate continuous, unexplained, or excessive usage.
Water Cost Recovery
Identify potential billing errors, overpayments, duplicate charges, and incorrect account information.
Water Efficiency Planning
Practical recommendations ranked by savings, cost, payback period, complexity, and operational impact.
Multi-Site Water Management
Benchmark locations, identify high-use sites, consolidate data, and prioritise action across an estate.
Ongoing Monitoring & Validation
Track consumption, validate future bills, identify anomalies, and prevent savings from disappearing.
Our process
A clear, five-stage process
Initial review
You provide recent bills, meter details, site information, and relevant consumption data.
Data & billing analysis
We review charges, tariffs, meter readings, consumption history, wastewater calculations, and unusual patterns.
Site investigation
Where required, we inspect meters, equipment, processes, operating hours, and potential leaks.
Findings & recommendations
A clear report setting out identified issues, estimated savings, priorities, costs, and payback periods.
Implementation & monitoring
We support corrective actions, supplier queries, efficiency projects, invoice checks, and ongoing performance tracking.

Illustrative case study
Multi-site retail estate
A retail group with 24 sites had no central view of water consumption. Invoices were paid without validation, and three sites were billed on estimated readings for over two years.
A billing audit and consumption review identified tariff misclassification at four locations, a continuous overnight flow at a distribution centre, and duplicate standing charges on two closed units.

Common questions
Frequently asked questions
How long does a water audit take?
A billing and consumption review is typically completed within two to three weeks of receiving your data. On-site audits are scheduled around your operations and usually take one day per site, though larger or more water-intensive locations can take longer.
Do we need to change water supplier?
No. An audit is entirely independent of your supplier arrangements. Many of the savings we identify — billing errors, tariff misclassification, leaks, and inefficient equipment — exist regardless of who supplies your water.
What information do you need from us?
Typically 12–24 months of water and wastewater invoices, meter numbers and locations, a list of sites, and basic information about operating hours and water-using equipment.
What if you don’t find any savings?
That is a legitimate outcome, and we will say so plainly. A clean audit still gives you a documented baseline, validated invoices, and confidence that your water spend is correct.
