First, do not cancel any direct debits and ensure you have let the retailer know if you are struggling to make payment. Failure to pay can lead to interest build-up and affect your credit.

Next – submit a new meter read. This will recalculate your usage on your next billing period and generate an accurate bill. From here you can clear down the balance or set up a payment plan.

The most common cause of bills being inaccurate is estimated reads: submitting regular reads is vital.

If you believe you have a leak: contact your retailer and request their support.

  • Take regular meter readings and cross check with your water bill
