Decided to switch suppliers for gas and electric. Check a few comparison sites and then go through quidco for cash back.
All gave me about a £150-£200 better off scenario except one.
Confused.com on 3 separate occasions now ( just in case a one off) have said I would be about £734 worse off at the very best. whomever I switch to.
This was all very amusing considering they are called Confused and that's exactly what I got.
Anyway I ended up switching from Npower to E'On £60 cashback and alls well in the world.
