Report Ios Investigation: The Great British Energy Rip-Off in House prices and the economy Posted October 21, 2012 The article doesn't give the reason, but from the figures, it's quite obvious why so there is this perceived monopoly. The overwhelming majority of households are still with their "default" provider that took over their supply at privatisation, and have never changed. Perhaps this is because changing is not perceived as useful, pricing is too opaque, or that people are too lazy (or too uniformed) to change to get a better deal. its almost impossible to see if u will save anything! I have tried to see if you can work this out and when I compared tariffs between companies, almost none of them were exactly the same, so you could NOT tell who would be cheapest for you atall. The way to deal with this is actually very easy. The Companies must be forced to provide say 4 tariffs that are exactly the same - ie amount per unit at a level amount whatever you use; a low user tariff with cheaper units to start then more expensive units; a high user tariff with tapering lower price per unit after so many are used etc. But all companies would provide the same formula. At present they are not reconcileable. If they have to do as I say then the first 4 tariffs presented MUST be the comparable ones. They can then offer any others they like. What's so difficult about that??!! I suppose David Cameron just shot his mouth off before anything had been thought through and now thee's a silly furore - that's UK idiot govts for you.
