Had my present firm not held on to £250 of my money I might not have changed. However they did and I found a supplier that needs £10 a month less and with a saving of £105 per year. So I changed, the readings have now gone in to finalise the change.
I can't say this enough.....Loyalty DOES NOT BENEFIT THE CONSUMER.......CHANGE NOW! U Switch will do it for you, it is seamless and not a bit painful.
