Octopus Energy vs EDF Energy (2026)

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.

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 new-joiner 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

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 Ofgem and 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 (and the friend who shared the link gets £50 too).
