How to set up Mint Energie energy for your home in France

The process is completely different depending on your situation — choose yours below.

If there is no active contract at your new address, the electricity will be off when you arrive.

This is very common in France. Always call your supplier before your move-in date — activation by ENEDIS takes 1–5 business days. A same-day emergency connection is possible but costs extra.

How it works

1
Find your PDL number
Your PDL (Point de Livraison) is a 14-digit meter reference unique to your address. Find it on a previous occupant's bill, on the meter itself, or ask your landlord. Without it, your supplier cannot open a contract.
2
Call before you move in
Contact Mint Energie (or Selectra in English) with your PDL, move-in date, ID, and French bank details. The whole process takes under 10 minutes by phone.
3
ENEDIS activates your meter
The grid operator ENEDIS (not your supplier) physically activates the line. Standard activation: 1–5 business days. Emergency same-day activation: possible but chargeable.
4
You receive a welcome letter
It arrives by post in French. It confirms your contract details, tariff, and PDL. Selectra can help you understand it if needed.

What you'll need

  • PDL number — 14-digit meter reference. On your Linky meter, on a previous bill left at the address, or via your landlord. This is mandatory.
  • French bank account (RIB) — Most French suppliers require direct debit (prélèvement automatique). If you don't have a French account yet, call Selectra — some suppliers accept foreign IBANs.
  • Passport or EU ID — For identity verification. A copy is sometimes requested by post after sign-up.
  • PCE number — Gas meter reference, equivalent of the PDL for natural gas. On your last gas bill or on the meter.
  • Move-in date — Needed to schedule activation. Give as much notice as possible.

Your electricity will not be cut off during the switch.

Switching supplier in France is handled entirely by ENEDIS in the background. Your current supplier is notified automatically — you do not need to cancel anything yourself.

How it works

1
Compare offers
Use the price grid above to compare Mint Energie tariffs against the market. Savings vs. the regulated tariff are common with alternative suppliers.
2
Subscribe
Call Mint Energie directly, or use Selectra's free English-language service. You'll need your PDL (on your current bill), RIB, and ID. Takes under 10 minutes.
3
Your old supplier is notified automatically
You do not need to contact your current supplier. The switch is handled by ENEDIS under French energy regulations. Processing takes 2–3 weeks.
4
Final bill and welcome letter
Your old supplier sends a final bill (in French). Mint Energie sends a welcome letter confirming your new tariff. Selectra can help you read both.

Key facts

  • No termination fee — French law prohibits exit fees on residential energy contracts. You can switch at any time, even mid-contract.
  • Timeline: 2–3 weeks — From sign-up to your first bill with the new supplier. Your meter reading is synced automatically.
  • You need your PDL — Find it on your current electricity bill (14-digit number labelled "PDL" or "Référence PDL").
  • Regulated tariff: you can always return — If you switch away from the regulated tariff (Tarif Bleu), you can come back to EDF at any time at the current regulated rate.

Mint Energie customer reviews: what to expect as an expat

Overall customer score

4.4 /5 Highly rated
PoorAverageExcellent

Average across 4 review platforms · 15,155 total reviews

What this means for you

Mint Energie consistently earns strong customer ratings — one of the better-reviewed suppliers on the French market. Most reviews praise pricing and contract clarity. Note that all reviews come from French-speaking customers; the experience for expats mainly depends on how you manage French-language correspondence.

Note for expats

All reviews are from French-speaking customers. Language barriers with customer service affect every supplier equally — Selectra's English service acts as your intermediary at no cost.

How the overall score of 4.4/5 is calculated

The overall score is a weighted average, not a simple average of the 4 platform scores. Each platform counts in proportion to its number of reviews, so a platform with thousands of reviews weighs more than one with a few dozen. For each platform, the score is multiplied by its number of reviews; the results are added up, then divided by the total number of reviews.

Ombudsman complaint rate

36 per 100,000 contracts

High complaint rate

Every year, France's Médiateur national de l'énergie — the independent national energy ombudsman — publishes how many residential customers filed a formal dispute against each supplier, per 100,000 contracts. A high rate means more customers had complaints that their supplier failed to resolve directly. Only large suppliers with over 50,000 residential contracts are included.

Mint Energie's rate of 36 ranks 15th out of 16 ranked suppliers (lower is better). The market average is 23.8 per 100,000 contracts. Mint Energie sits above the market average. This does not necessarily mean bad service, but it is worth bearing in mind — especially if you are not fluent in French and a billing dispute becomes harder to resolve.

About Mint Energie

Mint Énergie is a French supplier of renewable electricity and gas, known for pairing competitive prices with green energy. It always keeps one low-cost, more-or-less green offer on the market, alongside greener electricity and gas offers that come with stricter environmental guarantees at a higher price.

Our review of Mint Energie

Mint Énergie positions itself as a renewable energy supplier with very competitive prices — a combination that can seem paradoxical. That is why the supplier permanently keeps one more-or-less green offer at a very competitive price, while at the same time marketing electricity and gas offers with stricter environmental guarantees that are also more expensive. This strategy has paid off for Mint Énergie, which is seeing strong growth in its customer base.

As for customer service quality, Mint Énergie has come a long way and shows a particularly impressive improvement trend. In 2023, the supplier was going through a very difficult period, marked by a critical rate of 233 disputes per 100,000 contracts according to figures from the National Energy Ombudsman (Médiateur national de l'énergie).

Since then, the company has invested heavily to turn things around and restructure its services, managing to divide that figure by almost eight. With a rate now down to 30 complaints at the institution's latest assessment, Mint Énergie has moved considerably closer to the national average (set at 25).

While it still has one last effort to make to join the front-runners, this rapid progress reflects a genuine commitment to making its customer support more reliable and regaining its subscribers' trust.

Awards and rankings

Mint Énergie has received the following awards, trophies and labels:

  • Service France Garanti certification: First obtained in 2021, Mint renewed its "Service France Garanti" certification in July 2023. This label recognises its 100% French expertise and its local roots, both in its services and in its choice of partners.

  • "Engagé RSE niveau confirmé" label: Mint holds the "Engagé RSE niveau confirmé" label, reflecting its commitment since day one to a corporate social responsibility (CSR) approach for structural sustainable development, both social and environmental.

  • ADEME's VertVolt label: Mint Énergie's green electricity offer "Smart & Green PREMIUM" carries the "VertVolt, choix engagé" label from ADEME (France's ecological transition agency). This label guarantees greater transparency on green electricity offers and commits the supplier to buying both the electricity and the guarantees of origin from the same French green energy producer.

In the past, Mint Énergie won the 2019 Selectra Prize for Best New Supplier, a distinction awarded to an energy supplier with a portfolio of fewer than 100,000 customers.
