The verdict
EDF is a serious, financially solid supplier with genuinely low-carbon electricity and some sharp fixed deals, so it's far from a bad choice. But for most households weighing the two today, Octopus edges ahead on customer satisfaction, the breadth of smart tariffs and app experience — and uniquely, you can pick up £50 of welcome credit on the way in.
EDF Energy is the UK arm of France's state-owned Électricité de France and the country's biggest generator of low-carbon electricity, running Britain's nuclear fleet and building the new Hinkley Point C and Sizewell C plants. Tellingly, EDF has migrated its millions of UK accounts onto Kraken — the very customer platform built and licensed by Octopus Energy Group.
Where Octopus tends to win
- Consistently higher independent satisfaction scores — Octopus is a long-running Which? Recommended Provider with an 'Excellent' ~4.8/5 Trustpilot rating, while EDF's customer ratings tend to sit lower
- A far wider range of smart and dynamic tariffs — Agile (half-hourly wholesale pricing), Tracker (daily wholesale rate), Intelligent Octopus Go for EVs and Cosy Octopus for heat pumps go well beyond EDF's more conventional fixed and Economy 7 line-up
- All Octopus electricity is 100% renewable as standard, whereas EDF's domestic supply varies by tariff rather than being green by default
- Octoplus rewards plus Saving Sessions give Octopus customers free monthly prize spins and the chance to earn money for shifting usage — EDF has no direct equivalent
- A £50 welcome credit is available through a referral link when you join Octopus; EDF has no comparable joining bonus
Where EDF Energy still has a case
- EDF's electricity is genuinely one of the lowest-carbon in the UK because it generates so much from nuclear — a real plus if reliable low-carbon power matters more to you than the '100% renewable' label
- EDF is one of the largest and most financially stable suppliers, backed by the French state, and routinely offers competitive longer fixed-rate deals for households who want price certainty
- EDF caters well to EV and solar owners with dedicated tariffs and bundled home-charger deals, so it can suit specific setups nicely

Is EDF Energy cheaper than Octopus Energy?
EDF sometimes has sharp fixed deals, so on a fixed-vs-fixed basis it can occasionally undercut Octopus — but on standard variable rates they're similar, and Octopus's smart tariffs give more room to save if you can shift usage. Factor in the £50 Octopus credit, which EDF has no match for. Always compare live rates for your postcode on octopus.energy.
How to switch from EDF Energy to Octopus
Switching from EDF to Octopus is quick and completely safe: tap a referral link (the kind that looks like share.octopus.energy/word-word-number, which applies the £50 automatically), pop in your address and a recent meter reading, and Octopus handles the rest with EDF for you. It's all protected by the Energy Switch Guarantee, so there's no break in supply — same gas pipes, same wires, same meter — and most switches complete in about five working days. You don't claim the credit manually: roughly two to four weeks after your switch completes and your first monthly Direct Debit is taken, £50 lands in your account automatically.
