Our services

There are a wide variety of water services we feel you could benefit from, including:

Consolidated billing

Consolidated billing provides a convenient way in which to receive and manage your multi-site costs in one simple invoice. For multi-site customers we can also offer billing options that may be more preferential. If you wish to discuss this format of billing, for example you want to add supply points to a consolidated bill or receive all your bills at the same time each month, please contact us to discuss your billing preferences. For more information on this please email marked for the attention of Jacqui Thom.

Direct Debit

Monthly Direct Debit is the easiest way to pay your bills and allows you to spread your water costs evenly over the year. Many customers choose to pay by monthly Direct Debit, just follow the quick and simple process here.

Paying VAT on your water services?

It is possible that we will not have to charge VAT on your water services, but we are unable to assess your position without your completed SIC form. Simply complete and return the SIC form.

Meter reads

We take meter readings twice a year, or monthly if you are a large site or have a contract stipulating monthly reads. However, you can also provide additional meter reads yourself via our website (here) at any time.
