I've just switched over to Octopus energy as I wanted to switch over to reusable energy (and to get a fixed tariff given the uncertain times).
I used a referral link shared with me by another MNetter to get £50 off my bill.
If anyone here is thinking of switching, feel free to use my link below and we will both get £50 off:
