So many contacts and emails with First Utility - I just could not go through it all. Nightmare.
They offer no customer service. Constantly over estimating and over charging my bills. You provide meter reading, ignore them, and then over estimate it further. They ignore your readings - asking for another reading. Customer service via email - waste of time, they ignore what you say.
I tried to move to another supplier and they blocked my move! Why? Because I had not paid their over estimated bill!
I have just paid a bill and probably lost a load of money along the way - I just to get away from these lot.
(Be careful using money comparison sites.)
Much better to go for someone who can offer some kind of customer service. Someone who will provide honest bills.
