Best referral codes May 2026: finance, energy and SaaS archive

Finance: the month's highest bonuses

Finance remains the leading category for bonus amounts. Here are the five most appealing programmes in May.

BoursoBank, up to €130 for the referred person in May 2026. The programme was relaunched in April 2026 after being suspended in 2024 and was active that month. The referrer received €30, while the referred person could accumulate up to €130 (€20 welcome bonus, €30 referral bonus, €30 option, €50 EasyMove). This was one of the best referred-person bonuses in the banking market at the time of this report. Conditions: new customer, depending on the offers taken out. Current details are available in the BoursoBank guide.

Fortuneo, up to €150 for the referrer in May 2026. In this historical report, Fortuneo was the most generous for referrers: up to €150 per referred person for a PEA or a Gold card, €80 for a Fosfo card, with the referred person receiving between €80 and €100 depending on the product. The current rate has changed: do not rely on this historical report without consulting the up-to-date Fortuneo guide.

Revolut, variable campaign. As early as May 2026, the amount and conditions depended on the campaign displayed in the referrer's app. No single public amount should be inferred from this historical article: the offer visible in the app when the code is shared is the one that applies.

Trade Republic, one randomly selected share. One free share of random value (€5 to €200) for the referred person once their account has been opened and verified and the bonus conditions have been met. An ideally regulated broker for beginning investors.

N26, €15 for the referrer. The programme remained at €15 per referred person. A modest bonus, but an extremely simple process: the referred person opens a fee-free current account and the referrer receives their €15. Reliable and free from complex conditions.

Energy: the right time to switch supplier

Energy referrals are particularly attractive when someone close to you is considering switching supplier. The switch takes around 14 days, with no interruption: only the commercial contract changes, while the distribution network remains the same.

Engie, €45 for the referrer and €45 for the referred person. The sector's best-documented programme: €45 on each side, for up to 10 referred people per year, making a maximum annual total of €450. The market's most transparent energy bonus. Details are available in the Engie guide.

TotalEnergies, Octopus Energy, EDF. These three suppliers also offer programmes, but their amounts change frequently and may differ from third-party sources. Check directly on totalenergies.fr, octopus.energy/fr and edf.fr before sharing anything.

SaaS: free credits and months

For software, the reward rarely takes the form of euros. It is usually credits or free months, whose value depends on how you use the tool.

Lovable, 10 credits on each side. The AI-assisted application development platform gives 10 credits to the referrer and the referred person, which can be used to generate features and code (source: lovable.dev/faq/referral). Relevant for developers and creators already in the ecosystem.

Dougs, 1 to 2 months free. The accounting software for freelancers and small businesses offers 1 to 2 months of subscription for each party (source: dougs.fr), representing a genuine saving depending on the plan. Worth considering if you are a freelancer or run a small organisation.

Proton, $20 in credits. The privacy-first suite of tools offers the referrer $20 in credits if the referred person subscribes, plus a 2-week trial and $20 for the referred person (source: proton.me/support/referral-program). Ideal for people concerned about their digital privacy.

What changed this month

Two developments were worth noting in May. BoursoBank confirmed its April relaunch: after suspending its referral programme in 2024, the programme returned with its multi-tier offer of up to €130 for the referred person. This was the most notable development in online banking during the first half of 2026. Revolut, meanwhile, was already regularly adjusting its amounts according to markets and periods: the campaign remained active in May, with amounts to be confirmed in the app.

Good to know before using a code

A few simple rules help avoid disappointment. One code per registration: you choose one referrer per service, but there is nothing to stop you using a different code for each separate service, one for BoursoBank and one for Engie. The code is entered during registration, not afterwards, so prepare it in advance. Above all, using a code is always free for the referred person: beware of any website that asks for payment to access a code, as it is a scam.

Check before taking action: amounts and conditions checked on 23/04/2026 and may have changed since then. BoursoBank and Fortuneo did in fact change their rates after this archive. Always consult each brand's official referral page before registering. Some offers are subject to conditions, such as a minimum deposit, a specific product or new-customer status. PlanParrainPromo.fr is not a partner of any of the brands mentioned.

In summary

May 2026 was an active month: BoursoBank continued its post-relaunch momentum with a highly competitive referred-person offer, Fortuneo maintained a high bar for referrers, and Engie retained its position as the benchmark in energy. Since then, BoursoBank and Fortuneo's rates have changed. On the SaaS side, Lovable, Dougs and Proton offered genuine value to their users. In every case, check the official conditions before registering.
