How do you switch gas supplier without risking a cut-off? It is the first fear of most households, and it is unfounded: the process is free, framed by law, and your gas supply is never interrupted. Here, step by step, is what you need to know before taking the plunge.
Why there is never a cut-off
The most important point: switching supplier causes no gas cut-off and no meter replacement. In France, supply (the commercial contract) is separate from distribution (the physical delivery of gas). The latter is handled by the network operator, GRDF, whatever your supplier.
In other words, when you switch supplier, the gas keeps arriving through the same pipes and the same meter. Only the company that bills you changes. This is why no technical intervention is needed at your home.
The steps, reduced to a minimum
The good news is that cancelling your old contract happens automatically. When you subscribe with a new supplier for the same home, it handles cancelling the old one on your behalf. You therefore have no cancellation letter to send.
To subscribe, keep to hand:
- a recent invoice from your current supplier (it contains your meter number, the PCE, the metering and estimation point);
- a meter reading at the time of the switch;
- your bank details for the direct debit.
Subscribing takes a few minutes online. The effective time is generally about twenty calendar days.
A free switch with no commitment
Switching gas supplier is totally free. Article L. 224-14 of the French Consumer Code prohibits imposing on individuals any cancellation fee, penalty or indemnity of any kind. As gas contracts for individuals have no commitment period, you can leave at any time.
In concrete terms, you can therefore try an offer, then switch again if a better proposal appears, without ever paying anything to leave.
The special case of moving house
Be careful not to confuse switching supplier and moving house. If you move, automatic cancellation does not apply: you must take out a new contract for your future home and cancel the contract for the old home yourself. Plan these steps a few days before your arrival so the gas is active as soon as you move in.
How to choose your new offer wisely
Once you understand the mechanics, everything comes down to the choice of offer. The criteria to compare:
- The type of price: fixed-price offer (protected from increases for a given period) or indexed price (which follows the market).
- The level of discount on the kWh price and the standing charge.
- The quality of customer service and the options (electricity and gas bundled, “green” energy, etc.).

In summary
Switching gas supplier is a simple, free process with no risk of cut-off. The only real decision is the offer. Take the time to compare several proposals and always check the pricing terms before subscribing.
