The system that we use to review accounts and generate monthly direct debit payments works well and is one of the most robust in the industry according to the findings of an independent OFGEM report.
You can help to make your payments as accurate as possible by taking meter readings at regular intervals and sending them to our customer services area. If we are relying on estimated bills it will take longer for us to identify a problem.
We bill people on a six monthly cycle as this is more cost effective and enables us to make savings that we can pass on to our customers.
