What is the lowest bill guarantee?

Our lowest bill guarantee is our promise that you'll always pay the lowest bill when you switch to a meter. It works like this: every time we send you a bill, we'll compare your meter charges against what you would have paid on your old rateable value bill and always charge you the lower amount. Our lowest bill guarantee lasts for two years and if you've not made a saving in that time you can switch back to your old fixed bill. So you've got nothing to lose! Visit our meter section for further details on how to apply.
