I used ORG600 to change a combined tariff I already had with British Gas, with British Gas! The lowest rate offered direct with British Gas was more than going through ORG600 which seems ridiculous. Having completed the change, British Gas changed my electricity but left me on standard for Gas, I phoned them to highlight their mistake at which point they blamed ORG600 but had no answer when I pointed out that I had moved to a combined tariff so it must be their fault. They refused to do anything about it but fortunately Samir Hosenally from ORG600 sorted things for me within a couple of emails. Happy to recommend ORG600.
