What is the Endesa ‘Refer a Friend’ promotion?

The promotion is based on a simple process: recommend a friend to sign up for an energy supply and receive a financial reward in turn.

Understanding your referral: what it is and how to use it

The process is straightforward: an existing customer recommends a friend or acquaintance who doesn't yet have a contract. As soon as they complete a valid sign-up, both of you receive a financial reward.

Official validity period of the promotion

This is not a year-round campaign but is scheduled for specific dates as part of a wider strategy. On this occasion, the promotion will be active from 16 March to 16 April.

Customer rewards: €50 for every referral

The incentive is clear: a €50 discount on the bill for the referring customer. This is one of the most compelling energy promotions available, as the benefit is direct, measurable and straightforward. Better yet, you can maximise your savings by making multiple referrals.

Rewards for your friend: what’s in it for them?

It’s a win-win: new customers also receive a €50 discount on their bill. This helps drive conversions by offering the referred friend an immediate financial gain upon signing up.

Can I refer more than one friend? Limits and rewards

The scheme sets a clear limit of up to 10 rewarded referrals per customer. This means you can earn up to €500 in total discounts —a fantastic way to achieve real savings. Once this limit is reached, the original referrer will no longer qualify for additional rewards; however, any further new customers you refer will still receive their own discount.

Endesa products covered by this promotion

The promotion applies to electricity and gas contracts, as well as dual energy plans. This flexibility ensures the refer-a-friend model can be tailored to the new customer’s specific needs, significantly increasing the reach of the offer.

How to claim your €50 off: a step-by-step guide

The reason these promotions work so well is their simplicity. You won’t find any complex red tape or long-winded processes involved.

1. Send your referral link or code to a friend

The first step is to share your referral access, either via a link or a personal code. It’s essential that your friend uses this specific link when signing up to ensure the referral is correctly tracked and recorded.

2. Your friend signs up for electricity, gas or both

Next, your friend needs to complete their energy contract. They can choose electricity only, gas only or a combined dual energy plan.

3. Your referral is verified automatically

Once the sign-up is complete, the system automatically validates the referral. As this process requires no manual intervention, it provides a seamless experience for both you and your friend.

4. Discount applied to your bill

Finally, the €50 discount is applied directly to your next bill. There are no fine print or prize draws involved —it’s a real, tangible saving that directly reduces the amount you pay.

Eligibility criteria for your discount

While the process is straightforward, there are certain conditions that must be met to ensure your referral discount is valid.

Your friend must successfully complete their sign-up

The most important requirement is that your referred friend completes the entire contracting process correctly. The energy agreement must be fully finalised and meet all supply conditions; if this step isn't finished, the system won't be able to apply the discount.

The benefits of our refer-a-friend discount

The advantages of refer-a-friend promotion go beyond ease of use; it’s about the genuine value they provide over the medium and long term.

Immediate savings with no strings attached

One of the main benefits is that the discount is applied directly to your bill without any additional lock-in periods or hidden catches. It’s an immediate saving that reduces your energy costs with no extra commitment required.

Compatible with other benefits (e.g., PARA TI)

This promotion can be combined with other perks within the loyalty ecosystem, such as point-based reward programmes, additional discounts or complementary promotions. This allows you to maximise your savings by stacking different incentives together.

No limits on your referrals

Unlike other promotions that are limited to a single use, this scheme allows you to repeat the process and refer multiple contacts. This multiplies your rewards, turning a one-off saving into a long-term strategy for accumulating discounts.

Offsetting the impact of energy costs

Direct discounts are an effective way to shield yourself from fluctuating energy prices. These promotions act as a practical tool to help you stay in control of your  spending.

Maximising your referral rewards

Knowing the discount exists is only the first step; the real difference lies in the way you use it to your advantage.

Share your link with your trusted networks

Referrals work best within your inner circle —think family, close friends or colleagues. These trusted connections have a higher success rate for completing their sign-up.

Review your tariff to optimise your usage

Benefiting from energy promotions is a great first step, but understanding your own energy usage is essential. Periodically checking your tariff helps you spot potential improvements, adjust your spending and complement your savings with the discount.

Combine your discount with energy-efficient habits

While a referral discount directly lowers your bill, the impact is even greater when paired with energy-saving habits. Simple changes —like using energy responsibly and optimising your home’s consumption— will help you lock in those savings.
