Get £50 for free when you join Octopus Energy (the referee also gets £50). Plus £50 each time you refer a friend. I’ve been with a few energy providers, but have found Octopus Energy's website, customer service and prices to be great. Steps: Use this link - we get £50 each which will be credited towards our Gas/Electric future bill. Complete the quote and switch to Octopus Energy. You'll get £50 credited to your account once your switch is finalised and the first Direct Debit payment has gone through. If you're switching your company's energy, then the offer gets boosted to £100 each
