In France, bank fees remain a source of friction between financial institutions and their customers. Regulations cap certain types of fees, such as intervention fees (€8 per transaction and €80 per month in general), but other charges are not subject to strict limits. Identifying the most expensive banks or those with the least reliable service means looking beyond the annual total shown on comparison sites.
Hidden bank fees: charges that comparison sites don’t show
Annual rankings of the cheapest banks are based on standard profiles: an average consumer, a basic bank card and a set number of transactions. This standardised approach leaves out several charges that can add up for some customers.
Direct debit rejection fees are a good example. Regulations cap these fees at the amount of the rejected transaction, up to a maximum of €20 per rejection. If several direct debits are rejected in the same month, the bill can quickly mount up without the customer necessarily realising how much the fees total.
A report by CLCV highlights that customers with few banking needs—those who use few services but occasionally incur payment incidents—are hit hardest. Incident fees make up a disproportionate share of their total banking costs, something standard fee schedules don’t help them anticipate. To get a clearer picture of the worst banks in France, compare these incident fees rather than looking only at the cost of a bank card.

Financially vulnerable customers and the dedicated offer: a safety net that isn’t always applied
Regulations provide for a dedicated offer for customers in financially vulnerable circumstances, capped at €3 per month. For these customers, intervention fees are reduced to €4 per transaction and €20 per month. On paper, the protection is there.
The problem lies in identifying these customers. Banks assess financial vulnerability using their own criteria, including repeated payment incidents and the level of funds paid into the account. Five or more incidents in a single month trigger recognition of financial vulnerability for at least three months.
Why some eligible customers don’t receive the offer
Several factors explain the gap between the rules and what happens in practice. Banks don’t all use the same detection thresholds. A customer with four incidents in one month may go unnoticed by one bank, even though another would have identified them.
The dedicated offer isn’t always proactively offered. Some customers don’t know it exists, and banks may have little incentive to promote it, since it automatically reduces the revenue they earn from incident fees. The most reliable approach is to check your eligibility directly with your adviser or through the complaints department.
Bank customer service: what complaints reveal
Beyond fees, the quality of customer service is a key factor. Feedback on forums and from consumer associations points to recurring problems at some traditional banks.
- Complaints regularly take longer to process than the stated timeframes, with cases passed between several representatives without being resolved
- Phone support teams routinely direct customers to their branch, even for transactions that can be completed remotely, delaying matters for customers who live far from their branch
- Customers continue to face difficulties closing accounts or transferring products, despite the bank switching service designed to simplify the process
The annual fee statement, sent every January, is an underused tool. It lists every fee charged over the previous year, item by item. Comparing it with the bank’s fee schedule can reveal charges the customer didn’t know about.
Online bank or traditional bank: the pitfalls of a partial switch
Given the high fees charged by some banks, switching to an online bank may seem like an obvious choice. Fees are generally lower and may even be zero for account maintenance and bank cards. But other services may be limited.
Online banks don’t all offer the same services as a branch-based bank. Mortgages, cash and cheque deposits, and access to a dedicated adviser are common weak points. Customers who keep an account with their traditional bank for these services end up with two banks—and sometimes two sets of fees.
Before switching, check these key points
- Free card conditions (such as a minimum income paid into the account or a minimum number of monthly transactions) can lead to fees if they aren’t met
- Fees for maintaining an inactive account at your old bank can add up if you don’t formally close it
- Direct debits not transferred through the bank switching service can be rejected, resulting in incident fees at both banks
Choosing a bank isn’t just about comparing fee schedules. Incident fees and how quickly customer service responds matter more than the headline cost of a card for customers who occasionally go overdrawn or have payments rejected. Reviewing your annual fee statement, checking whether you qualify for the offer for financially vulnerable customers, and comparing the actual terms for leaving before switching banks are the three most useful ways to keep costs down.
