Octopus Energy vs Ecotricity (2026)
If your priority is putting every penny toward building new renewable infrastructure, Ecotricity is a genuinely principled choice with a long pedigree. But for most households, Octopus matches the 100% renewable electricity while adding far more competitive everyday pricing, a much wider range of smart tariffs, a stronger app and top independent satisfaction scores. For the typical bill-payer comparing the two, Octopus is the more practical pick - and you can pick up £50 of welcome credit on the way in.
Switching from Ecotricity takes ~5 working days with no break in supply — and my link gets you £50.

The verdict
If your priority is putting every penny toward building new renewable infrastructure, Ecotricity is a genuinely principled choice with a long pedigree. But for most households, Octopus matches the 100% renewable electricity while adding far more competitive everyday pricing, a much wider range of smart tariffs, a stronger app and top independent satisfaction scores.

Ecotricity was founded by Dale Vince in 1995 and sold its first green electricity to Cheltenham and Gloucester College in 1996, making it the world's first green energy company; it remains a small, independent supplier with around 167,000 customers and is the only vegan-certified energy company in the world.
Where Octopus tends to win
- Pricing: Ecotricity's Green Variable tariff holds a permanent derogation from the energy price cap, so it sets its own prices and is rarely the cheapest. Octopus tariffs track the cap and are consistently competitive - check current rates on octopus.energy as they vary by region.
- Tariff choice: Octopus offers a genuinely deep smart-tariff range - Agile (half-hourly wholesale pricing), Tracker (daily wholesale rate), Intelligent Octopus Go for EV charging, Cosy for heat pumps and Outgoing for solar export. Ecotricity's line-up is far narrower.
- Independent track record at scale: Octopus is the UK's largest electricity supplier (around 1 in 4 households), a multi-year Which? Recommended Provider with an Excellent ~4.8/5 Trustpilot rating across a vast review base.
- Rewards: Octoplus gives free monthly Wheel of Fortune spins and paid Saving Sessions - everyday perks Ecotricity simply doesn't run.
- A £50 welcome credit for switching via a referral link, paid automatically - Ecotricity has no comparable joining bonus.
Where Ecotricity still has a case
- Ecotricity has arguably the deepest green pedigree of any UK supplier - founded in 1995 as the world's first green energy company, it reinvests its margin into building new wind and sun parks (its 'bills into mills' model) rather than just buying renewable certificates.
- Its customer service is genuinely well regarded, topping Citizens Advice's supplier rankings and holding a solid Trustpilot rating in the low 4s.
- For ethically-motivated customers it offers things Octopus doesn't, including being the world's only vegan-certified energy supplier.

How to switch from Ecotricity to Octopus
Switching from Ecotricity to Octopus is quick and completely safe. Tap a referral link (it looks like share.octopus.energy/word-word-number and applies the £50 code automatically), enter your address and a meter reading, and Octopus arranges everything with Ecotricity for you - there's no need to contact them yourself. Your gas and electricity supply is never interrupted because it's the same pipes, wires and meter; the switch is protected by the Energy Switch Guarantee and usually completes in about 5 working days. Around 2 to 4 weeks after your switch completes and your first monthly Direct Debit is taken, £50 of credit lands on your account automatically - no claim form needed. Just make sure you use the referral link directly: signing up through a price-comparison site, a shortened URL or by typing the Octopus address yourself usually means the bonus won't apply.
