We want to develop open and honest relationships with you. We have a unique role within the UK energy sector and often have to balance many competing priorities. Sometimes, unfortunately, we are not in a position to say 'yes' to a request. So, if we say 'no', we will take the time to explain our business decisions to you.

If you are not happy with something, we will give the relevant part of the business the opportunity to put it right.

If you remain dissatisfied you will be able to contact us by phone, by email or in writing through our complaint process.
