Octopus Energy Referral Code 2026: €20 Off Your Bill

Signing up with Octopus Energy takes less than 10 minutes online: your meter point number (PDL), estimated annual consumption, contact details, bank details. The journey is designed to be simple and clear, in the tradition of the British group that built its brand on transparency and customer experience.

Octopus Energy has been present in France since January 2022, following the acquisition of Plüm Énergie, a French green supplier founded in 2016. Former Plüm customers were migrated automatically to Octopus. The switch is handled by the grid operator Enedis, with no power cut, in 2 to 4 weeks after signing.

The Octopus referral (€20 referee + €40 referrer) is activated via our link from your first bill after the contract goes live.

Octopus Energy's flagship offer in France is Eco-conso Fixe, available in juin 2026 at €0.1909/kWh incl. tax (Base option, 6 kVA), about -6% versus EDF's regulated Blue tariff. All Octopus electricity offers are 100% green and VertVolt-labelled — Guarantees of Origin certify local French renewable generation.

Octopus Energy also offers an Agile option (a dynamic hourly tariff based on market prices), hugely popular in the UK, which lets homes with a Linky smart meter consume during off-peak hours and save on their bill. This innovative model sets Octopus apart from traditional suppliers.

The offer is commitment-free, cancellable at any time without charge.

Octopus Energy handles the cancellation of your old contract when you sign up — no steps to take with your current supplier. Enedis manages the technical switch with no power cut, in 2 to 4 weeks. Activation is confirmed by email.

The Eco-conso Fixe offer locks in your kWh price for the contract's duration, with no unilateral revision. This is a significant advantage in a market where tariffs can fluctuate. At any time, you can switch to the Agile offer (dynamic tariff) if you want to optimise consumption during off-peak hours.

Octopus Energy commits to total pricing transparency: all charges are shown, with no hidden costs. Customer service is quick to reach, which is reflected in its very low dispute rate (13/100,000 contracts, versus a national average of 50+).

Searching for "Octopus Energy promo code" actually corresponds to the referral programme: Octopus does not hand out a public alphanumeric code, but offers a personal referral link to share. Our page automatically encodes the welcome benefit (€20 referee) into your sign-up.

The terms "Octopus Energy promo code", "Octopus voucher" and "Octopus Energy referral" therefore all mean the same thing. The benefit is among the best on the market: €40 for the referrer and €20 for the referee.

To compare with suppliers offering an even more generous referrer bonus, Plenitude gives €50 per referee. For households that prioritise customer service, Octopus (4.8/5 Trustpilot) is the undisputed market reference.

The Octopus Energy referral applies to all new subscriptions to electricity offers (Eco-conso Fixe, the Agile offer and others). Octopus also offers a gas option, which is also eligible for the referral.

The Octopus wallet is an internal credit system where referral rewards (€40 referrer) can be accumulated and used to reduce future bills or paid out directly. This wallet system is more flexible than a one-off discount on the next bill.

Octopus Energy also offers a plan dedicated to customers with an electric vehicle (pricing optimised for night-time charging), in the spirit of the Agile offer — innovative offers not yet found with every competitor.

Octopus Energy is not the cheapest supplier on the market, but it is the undisputed leader on service quality: 4.8/5 Trustpilot and only 13 complaints per 100,000 contracts. A decisive criterion for households that value service as much as price. By contrast, a large national supplier like TotalEnergies attracts mainly through its referral (€20 per referee) and its -10% Access offer, a positioning geared more to price and brand awareness than service quality.

Octopus Energy is the French subsidiary of the British Octopus Energy Group, founded in 2015 in London by Greg Jackson. The group is now present in more than 15 countries (UK, Germany, Spain, Japan, Australia and more) and supplies millions of customers worldwide.

In France, Octopus established itself by acquiring Plüm Énergie in January 2022 and kept the reputation for service quality that defines the brand in all its markets. Its 4.8/5 Trustpilot rating (with thousands of reviews) makes it one of the best-rated energy suppliers in France.

Our verdict: Octopus Energy is the obvious choice for households who never want to have to fight their supplier — responsive customer service, transparent billing, a near-zero dispute rate. The price gap with the cheapest green suppliers is real, but Octopus's customer service has a value that is hard to put a figure on.

The Octopus Energy referral is reserved for new customers who have never had a contract with the supplier. The referrer credit (€40) is paid to the Octopus wallet or the bill, at the referrer's choice; the referee credit (€20) is applied to the first bill.

Octopus Energy serves mainland France via the Enedis network for electricity and GrDF for gas. The Agile offer (dynamic hourly tariff) requires an activated Linky smart meter in remote-reading mode — check your eligibility before subscribing to that offer.

The Eco-conso Fixe and standard offers are available to all households in mainland France, with or without Linky. We check the conditions and tariffs regularly to give you the most up-to-date information.

Plüm Énergie was founded in France in 2016 as an independent green electricity supplier, before being acquired by the British Octopus Energy Group in January 2022. This acquisition let Octopus enter the French market with an existing customer base and operational infrastructure, without having to build a presence from scratch.

Since 2022, Octopus Energy France has continued to develop its offers, notably by adapting its innovative products to the French market, such as the Agile offer (dynamic tariff), much appreciated by tech-savvy customers in the UK.

Octopus Energy Group is also the owner of an energy technology studio (Kraken Technologies) that builds the energy-management platforms used in several countries. This tech dimension is a durable differentiator. We update this page regularly.
