The previous owner was with E-on and I've just been on compare the market. They are going by the address so saying it's based on my current usage - which is obviously hers - at £163 a month. That feels a lot but I just don't know.
If I was to change suppliers would it be a big job as I'm assuming they'd have to change the meters etc?
I've not heard of the company CTM is suggesting and say annual cost is £1685.
