npower go fix 6 v edf fix v2

big-azza

Im currently on edf online saver v6 and im paying £24 gas and £30 electric. Checked the comparison sites and both npower and edf are very similarly priced (£4 difference). If i go with npower through tcb i can get £80 cashback and because my brother works there he'll get £100 vouchers end of year. im sure i read on the t&c's of my online v6 tariff that if im a duel fuel customer with edf after a year il get a £100 credit. do i still get that if i switch to a different tariff and which one would you choose. tried ringing edf to find out but been on hold for 1hr

thanks
