Just like to add my appreciation too. It really a is great to have all this info in one place. We have been with EDF for about three years and am pleased to see that, although it’s variable, they do try to stay competitive it seems. I have no reason to switch just now (which is a relief bearing in mind the hassle of doing so). We have an electric aga so it works well with that and if you run all your main appliances at off peak times I think that makes it preferable to other tariffs.
Keep up the good work.
