This could be a problem with your ‘change of supply’ reading.  Please send us your up-to-date meter reading and any other historic readings you may have to

We will then contact your previous supplier and agree a new ‘change of supply reading’ based on your readings.  As we have to rely on your previous supplier responding to us we cannot give exact timescales as to when this will be resolved; however, we will do our best to complete it as quickly as possible for you.

You can make estimated bills a thing of the past by giving us your meter reading between the 25th of the month and the 1st of the following month.

It is possible that a meter exchange has taken place and the National Grid has not been updated with the new details.  Please check if there is a yellow sticker on your meter, as this will have details of the exchange.  Please contact us and we will be happy to check this for you, send us an email to or call us on 01423 502 554.
