Iberdrola Referral 2026: €25–€40 Credit Each for Bringing a Friend

Iberdrola is a Spanish electricity and gas supplier. Mi Iberdrola is its free loyalty programme for qualifying household energy customers, offering credit, partner discounts and other benefits. Its bring-a-friend offer is a specific promotion inside that programme, not a universal coupon. A referral must lead to a new eligible contract and the invited customer must also register for Mi Iberdrola through the invitation. The terms say this benefit applies when the referral promotion is active; check the current invitation screen before promising a reward.

Both parties earn the same tier-dependent monthly credit for twelve months: €2.09 for basic Mi Iberdrola (approximately €25.08 total), €2.50 for Plata (€30), €2.92 for Oro (€35.04), and €3.34 for Plus (€40.08). Iberdrola's public table rounds these to €25, €30, €35 and €40. The tier is the inviter's tier at the moment the friend signs up, not the friend's tier. Do not confuse these referral credits with the separate one-time €5 loyalty joining credit.

1. 1

   Check your loyalty account

   Sign in to Mi Iberdrola and confirm that the bring-a-friend promotion is available for your tier.

2. 2

   Copy your own invitation link

   Use the official invitation or contracting link shown in your account; a generic homepage visit is not equivalent.

3. 3

   Let the friend contract as a new customer

   The friend opens that link and signs up for an eligible household electricity contract.

4. 4

   Join Mi Iberdrola

   The invited person must register for the loyalty programme through the referred flow.

5. 5

   Keep contracts active and check credit

   Both people monitor monthly credit over twelve months; conditions must remain satisfied for each instalment.

The inviter must be registered in Mi Iberdrola and keep at least one active electricity contract to receive monthly credit. The invited person must be a new customer, contract through the personal link, qualify for and join Mi Iberdrola, and keep the referred contract active on each payment date. Eligible residential products include electricity 2.0TD and, for natural persons, 3.0TD; the wider loyalty programme also covers household gas RL1–RL3. However, the referral-payment rule specifically requires the inviter's active electricity supply. Public bodies are excluded from Mi Iberdrola, and overdue debts can prevent registration or redemption. A mobility-only Mi Iberdrola GO user is not automatically eligible for the referral credit.

• No generic code: the personal contracting link is essential.
• The friend must be a new qualifying customer and join Mi Iberdrola.
• Inviter needs an active electricity contract for their own monthly reward.
• An invited contract that becomes inactive can stop future credit.
• Up to ten invitees; no repeated referral between the same two people.
• Debt can block use of credit while the expiry clock continues.
• Credit expires after twelve months; it is not withdrawable cash.
• The offer is conditional on an active campaign and current terms.

The official conditions describe twelve monthly credit instalments, rather than one immediate €40 payment. Each payment depends on active contracts on that date. If the inviter has no active electricity contract, they lose their own referral credit, while the friend can continue to receive theirs if their qualifying contract remains active. If the friend cancels the referred contract, future instalments are at risk. Keep contract confirmation and screenshots of the invitation; contact Iberdrola if an expected instalment does not appear.

Mi Iberdrola credit can be redeemed through the customer app for electricity or gas bill discounts, eligible gift cards and products, or public EV charging; available options depend on the account. It cannot be withdrawn as cash. Each amount of available credit expires twelve months after it is earned. Unpaid bills can block redemption without pausing expiry. Cancelling all eligible contracts can mean losing available or pending credit. Review the app balance regularly instead of treating the headline €40 as cash in your pocket.

A customer can have at most ten invited friends. A person can be an invitee only once per calendar year, and the same pair cannot repeat the referral relationship in either direction. The published conditions also state that Iberdrola promotions for the same concept generally cannot be combined. The October conditions were published for 1 October through 1 November 2026 and provide for automatic renewal if no replacement terms are published; check the current document and the active campaign before contracting.

Compare the annual electricity price, standing charges, consumption rates, taxes and any optional services before switching. A €25–€40 loyalty credit spread over a year may be outweighed by higher bills. Make sure the friend genuinely needs a new qualifying Iberdrola contract and can keep it active. ReferTree is independent of Iberdrola and does not provide a generic code or guarantee that a referral will be approved.
