Been ok 1st 12 months ...my renewal is up price is now slightly more expensive than some .. 1 of the big 6 is slightly cheaper on units on both gas and elecy ... was going to stay with them so went on online chat .. as they want their payments heavy 1st 6 months then drop by 100 quid a month ..asked them if they can even out the the DD over 12 months so we can budget for the year ....operator on chat got all shirty nope and BTW you owe us make sure you get your account in order to £40 otherwise it will be queried and you be blocked from leaving ... Bearing in mind the DD that goes out end of month hasn't been processed yet ...when i have gone over i have always rung in and paid off the excess... ...Dont you worry pal....account will be squared up oh right .... ... as others have reported ..my experience is of there service is good until your leaving ...if your looking else where check all the comparison sites against their offer on gas and electricity per unit better deals out there in my region and that is based on my evidence doing my own research
