I was with HUB Energy so am in the process of being switched onto an E-on Next tariff. However, I like the look of the Sainsbury's Energy tariff as it's identical to E-on except that you get Nectar points with it.
As they are one and the same company in terms of supplying electricity & gas, is switching between the two quick or do you have to go through the same long process that you would do when switching to another provider? How would I go about doing this?
Thanks
