I changed over to Octopus just over a months ago, transferring easily and smoothly and it is the best thing I have done. I can't believe how good they are, their customer service is exceptional, via email, I no longer have to hang on the phone for hours ending up stressed and frustrated. Their administration via email is absolutely spot on. I gave my meter readings yesterday afternoon and straight away I had my bill - it was laid out simply and easy to understand, showing my readings, how much Gas and Electricity I had used etc. I am really happy with the price. Have not had any reason to contact them as all so far has been fine.
