Absolutely awful, I wouldn't set up DD as I didn't have one with SSE, the same reason for not setting up an email account. Kept trying to sell me smart meters, told them no. They then asked for photographs of my electric and gas meters. I told them they were welcome to come and see them, nobody bothered to turn up. I didn't pay them for 3 months due to their figures( wildly inaccurate estimates!) Not agreeing with the figures I sent in by phone. I would not ring them to sort out the problem, they sent me a debt collectors letter and added a £10.00 late payment to my bill. My cousin who is a barrister wrote and informed them that I was willing to pay but the figures had to reflect my usage and that I would not pay the late fees. The next bill arrived, it was £ 450.00 less than their last bill and the late payment fee had been removed as a 'good will payment'. This bill agreed with my figures, I paid it and told them I was leaving. I am now happily with Octopus, cheaper gas and electric, cheaper standing charge and great people to deal with.
