Thanks i.m curremtly looking on their site now.

Try ebico. I believe they charge the same whatever meter or payment method you adopt.

I.am currently paying £30 per week for gas and £20 per week for electricity on pre-payment meters, can anyone give me advice on switching. I believe it is cheaper not to have pre-payment. I.ve trawled through the energy saving companies but can't find anyone that will exchange the meters. Regards Angela
