In the short time I have been with Bulb, they have increased the price of fuel twice. While they did not sign a guarantee the price would stay the same for a year, the increases came thick and fast, within a couple of weeks of me signing up. Then a couple of months later. Having smiling people as logos and art work does not detract from the fact that this is a sting in the tail. I am now tied into the contract for a year. I will not renew and I would not recommend them.
