Octopus Energy stands apart from traditional suppliers by offering a range of innovative tariffs designed around how people actually use energy. While the Big Six typically offer just fixed or variable rates, Octopus gives you eleven distinct tariff options — each targeting a specific use case. With the Ofgem price cap at £1,663/year for a typical household and baseline rates of approximately 26.11p/kWh for electricity and 7.33p/kWh for gas, many of these smart tariffs can significantly undercut standard pricing.
One thing that applies across all of them: Octopus charges no exit fees on any domestic tariff, fixed deals included. That matters more than it sounds — it means picking a tariff isn't a commitment, so you can switch now, take the £50 credit, and change your mind once Ofgem confirms the October price cap on 26 August. If you're weighing certainty against flexibility, start with should you fix your tariff.
Below you'll find a complete comparison of every tariff, followed by a decision guide to help you pick the best one for your situation. Whichever you choose, you can switch in about 5 minutes and get £50 free credit with our referral link.
