Ready-reckoner

The impact of new improvements on water and sewerage bills

We have developed the ready-reckoner so that customers and other stakeholders can work out the impacts on future bills of spending on new improvements.

The ready-reckoner allows a simple, quick conversion from new costs in millions of pounds to the effect on bills. It is based on the more complicated calculations that we carry out when we set prices.

More detailed information about the ready-reckoner, and about how we pay for the water and sewerage services we currently receive, is available in our ready-reckoner leaflet.
