I have been with Opus energy for the last four months, they cold called us, told us that their energy rates are the best in the country and as long as consumption remained the same we'd be charged less than our current provider, so we decided to switch. So the first three months the bill was lower by a few pounds, this months the price has shot up to OVER 10 TIMES HIGHER with the same or less consumption of energy. This company will *** you, you're better off sticking to a well known reputable company like BRITISH GAS!
