Water deregulation in 2017 gave the opportunity for businesses in England to source the best water tariffs. Businesses in Scotland have been able to source tariffs since 2008 but those in Wales continue with Welsh Water. Before deregulation retailers weren’t much challenged but like energy, the market is complex requiring professional investigation and advice. We have found evidence of historical and metering issues, poor tariff selection and the implementation of unwarranted charges.

Analysis and Insight

Our philosophy is to conserve resources by reducing waste, however and whenever it occurs. So, our first step investigates your billing. As fiercely independent consultants we analyse your water billing to understand your consumption patterns as well as examining current tariffs and associated costs. There is little point in continuing a tariff or billing structure which is fundamentally unfit for purpose.

Refunds and Disputes

Overpayments occur for many reasons. If our investigations prove that refunds are appropriate, we pursue the retailer to make repayments direct to you. Similarly, if you have a dispute with your retailer, we are happy to investigate and intervene. Finally, if we believe reduced tariffs are applicable in the future, we will seek implementation. We don’t charge upfront fees, but we ask for a share of any refund or savings you may receive.

Our highly developed investigative and analytical skills have achieved outstanding successes. To date we have succeeded with every claim made to water retailers on our clients’ behalf.



Following appraisals, we seek from a panel of retailers the most appropriate and most cost-effective tariffs and charges. Our panel means we can find one of the best tariffs available. We challenge and manage water retailers to ensure that going forward they provide comprehensive, transparent and supportive services.
