Octopus Energy Offer Summary
How to get the best from Octopus
Sign up to a Flexible or Fixed tariff. Once you're switched and your first Direct Debit has been paid, you'll receive a £50 credit (T&Cs apply). If you want a smart tariff like Tracker, you can switch to it once you're set up — you'll need a working smart meter. Once you're a customer, you can also join Octoplus — Octopus Energy's free rewards programme. Octoplus Perks currently include (April 2026) a free weekly drink at Caffe Nero or Greggs and 2 Vue cinema tickets for £8 (codes subject to availability).
