I bought a property where its already have octopus as a supplier. I had worse experience with them before so i switch to my previous supplier after 20 days. My gas boiler was never working as house left empty for long time before i buy and i sent them gas meter readings before and after with no usage and no change in numbers but they magically sent false, wrong reading number and tried charge me £97 for gas, they did not know the old gas boiler completely broken. Every one make sure you check your bill and track it down before you pay your hard earn money as this is fraud
