Fixed Term normally means that the price (e.g. standing charge and per unit) are fixed for the duration of the contract (e.g. 12 months). OVO can't put your prices up until that 12 months is over. Your Direct Debit amount may go up or down depending on how much energy you are using, but the price you pay per unit for that energy, won't change during your contract. It also normally means that there are exit fees if you wish to leave early and transfer to another supplier.
