Just doing some comparisons my self. 104 year old 3 bed mid terrace, £69 month dual fuel. Current deal has come to an end and i’m getting a refund of £220… Cheers Scottish power.
About a year ago i had a lot of work done on the house, new boiler and loads of insulation included. Its a remarkable difference, it really is. Before with my old un-economical boiler, payments went to £137 a month (jan 2013)
I also give monthly meter readings so its always accurate
