Just sharing my code if anyone is looking to switch and wants a free £50 credit - I get £50 credit too so it would be a huge help towards bills!

I like Octopus because I can change my own direct debit in the app. They have a 'crystal ball' prediction tool so I can see what it's likely to cost over the next year and adjust my payments accordingly. I've heard horror stories about other suppliers setting ridiculous direct debits and people having to argue on the phone to try to change them!
