Our energy fix ends this month and I am looking for a new supplier, or at least new price plan. I've looked on a comparison website. The suppliers that seem to offer the biggest advantage over my current supplier are companies I haven't heard of. Would I be stupid to stick with my current supplier (they have a tariff which is now cheaper than the one I am on but it's about 4th in the list) just because they are a fairly well known company (edf) and I am used to their online system?
