Comparing Octopus Energy and EDF Energy? Here’s an honest breakdown — covering pricing, customer service, smart tariffs, EV charging, and the £50 referral credit you get when you switch to Octopus.
Switch from EDF – Get £50 Free →EDF Energy is one of the UK’s largest electricity suppliers, backed by the French state-owned EDF group. It’s a stable, established supplier — but stability and satisfaction are not the same thing. EDF’s Trustpilot scores and customer satisfaction data consistently trail Octopus by a wide margin.
For most UK households in 2026, Octopus Energy is the better choice: better customer service, better smart tariff options (especially for EV and heat pump owners), 100% renewable electricity as standard, and a permanent £50 referral scheme.
The only meaningful reason to stay with EDF is if you’re mid-way through a fixed-rate deal with significant exit fees that make switching uneconomic in the short term. Once that deal ends, the data clearly points to Octopus.
| Factor | Octopus Energy | EDF Energy |
|---|---|---|
| Trustpilot rating | 4.8★ Excellent (800,000+ reviews) | ~2.5–3★ (significantly lower) |
| Which? Best Buy | 7 times (2018–2025) | Not awarded in recent years |
| Pricing vs Ofgem cap | Always at or below cap since launch | Typically at or near cap |
| Renewable electricity | 100% as standard, all tariffs | Optional — not standard on all tariffs |
| EV tariff | Intelligent Octopus Go: 8p/kWh overnight | EDF EV tariff: higher overnight rates |
| Heat pump tariff | Cosy Octopus — save up to £389/yr | No dedicated heat pump tariff |
| Solar + battery | Octopus Flux / Agile Octopus | Limited smart tariff range |
| Referral scheme | £50 each (£100 split) — permanent | No permanent referral scheme |
| Exit fees (variable tariff) | No exit fees | No exit fees on variable tariffs |
| Ownership | UK-founded, independent | French state-owned EDF group |
EDF Energy’s Trustpilot score has historically sat in the 2.5–3★ range — which is typical for traditional big-six suppliers where billing disputes, long hold times, and complex complaint processes are common sources of frustration.
Octopus Energy’s 4.8★ Excellent from over 800,000 reviews is not just better — it’s in a completely different tier. Seven Which? Best Buy awards across 2018–2025 reflect sustained, consistent outperformance on billing accuracy, problem resolution speed, and overall satisfaction.
Octopus uses a team-based customer service model where a small group of agents handle your account throughout — meaning you deal with people who know your situation rather than repeating yourself to a new call-centre agent each time.
This is where the gap widens most significantly. Octopus has built its business around smart tariffs for low-carbon homes. EDF’s smart tariff range is more limited.
Under the October 2026 price cap of £1,723/yr, the value of a smart tariff that undercuts the standard rate is greater than ever. Octopus customers on Intelligent Octopus Go at 8p/kWh are paying around a third of the standard variable rate on their overnight usage.

For most customers in 2026, yes. Octopus holds Trustpilot 4.8★ vs EDF’s ~2.5–3★, has won Which? Best Buy seven times, and offers smart tariffs (IOG for EVs, Cosy Octopus for heat pumps) that EDF cannot match. EDF is a stable supplier but its customer satisfaction scores and smart tariff range lag significantly.

EDF has run occasional promotions but has no permanent refer-a-friend scheme. Switching to Octopus via a referral link earns both you and the referrer £50 credit each — consistently, year-round.
On standard variable tariffs, both track the Ofgem cap so headline rates are similar. Octopus is cheaper if you have an EV (IOG at 8p/kWh) or heat pump (Cosy Octopus, saving £389/yr). EDF’s EV tariff rates are higher than IOG’s overnight rate.
