Our complaints procedure

Step 1

We will always look to resolve your complaint at the first point of contact. The person answering your call will attempt to resolve matters with you whilst you are on the phone. However, if necessary, your complaint will be escalated to a manager. If a letter, email or customer contact form via our website is sent to our head office or a sales depot, the relevant staff member will aim to acknowledge receipt within two working days and aim to resolve your complaint within five working days.

Step 2

We would like to resolve your complaint at Step 1. However, if you do not receive a satisfactory response then you can raise the issue with our Senior Customer Relations Manager, who can be reached Via post: Aileen Till Certas Energy UK Ltd, First Floor, Allday House, Warrington WA3 6XG

Via email: A response will be sent in writing via letter or email to acknowledge the complaint and indicate when you can expect a reply. An internal review team will aim to reach a resolution on the complaint within 15 working days.
