Stepped tariff for Southeast region customers

Stepped tariff information

We are currently trialling an alternative measured tariff in the town of Lydd.  Approximately two thirds of customers there are on a stepped tariff designed to promote a reduction in water consumption.

There are two parts to the tariff, an essential use allowance of 80 cubic metres per property each year, (219 litres per day) designed to cover all essential household needs including cooking, washing and laundry requirements.  This is charged at about ¾ of the standard measured tariff.

All water used in excess of the essential use amount is charged for at approximately double the standard measured tariff. Customers with larger families are able to claim an increased volume of water for essential use as are those with special medical needs.

If the trial proves to be successful the Company will seek to introduce a similar form of tariff across it’s entire customer base in 2013.

Bishop Stortford Seasonal Tariff Trial Project Summary

The Seasonal Tariff Trial has enabled Affinity Water Ltd to be among the first water companies in the country to implement a forward thinking and environmentally sensitive approach to water resource management.

For a detailed summary of this project please click here.


What was the seasonal tariff?

From 1st April 2009 we were piloting a new charging scheme within the Bishops Stortford area to encourage more efficient water use in the summer months when the environment is most vulnerable. Customers within the pilot area paid a lower rate for water for eight months of the year and a higher rate from May to August.

From April 1st 2013 the trial ceased. If you were covered by the scheme, from April 1st you will be charged on the standard metered tariff. There will be no other changes and meters currently in place will remain.

We would like to thank customers for their support during the trial and we will be reporting the results of the trial, on these pages, later in the spring.

Other questions

Why not fix more leaks instead?

We invest around £18 million each year finding and fixing leaks and over the five years 2005-2010 we will spent £140 million replacing 640 kilometres of water pipes. With 14,000 kilometres of pipe work this is just the tip of the iceberg in ensuring that our infrastructure can meet the demands of all of the customers that we serve.

We would like to renew every pipe before it’s likely to burst but this would mean much higher bills than at present. When planning for the future we work out where to spend money and in reality we will invest in a range of steps to improve the availability of water, such as pipe replacement, metering, preventing pollution of water, and promoting water efficiency.

Is there any financial assistance available?

We operate a scheme called WaterSure which will cap bills at a certain limit. To qualify you must be receiving one of the qualifying benefits and either have a medical condition requiring high water use or, have three children under the age of 19 living with you.
