It compares your actually cost (based on the tariff you were on at the time) with the current version(s) of tariffs, or it can compare two (current) tariffs based on your actual usage. You cannot compare any two tariffs that have ever existed, if that's what your are trying to do. Octopus Compare is they only thing I know that can do that, I dont know why you think £2 a year "is a joke" (or where you get that from, its 0.49p per month, or £5 per year). The subscription gives you more views (like year, or custom).
