Purchase of a product: commercial or contractual guarantee

Verified 04 May 2022 - Directorate for Legal and Administrative Information (Prime Minister)

The commercial or contractual guarantee allows you to get a refund, to replace or repair a purchased product (household appliance, car, armchair...). It is proposed freely by the vendor or manufacturer. It can be free or paid for. It is optional and of variable duration.

The commercial or contractual guarantee is different from the guarantees legal compliance and hidden defects. It adds to them and can extend them, but does not replace them.

The commercial or contractual guarantee is defined by the seller. It is the government that freely determines its content in a contract.

The commercial guarantee may cover one or more of the following situations:

  • Refund your purchase,
  • Repair of your property (computer, washing machine...)
  • Replacement of your failed property.
  • Provision of any other services related to the property

This warranty may take different names: conventional warranty, contract warranty, manufacturer warranty, manufacturer warranty, warranty extension, refurbished exchange...

Commercial or contractual guarantees are distinct from guarantees legal compliance and hidden defects.

The commercial guarantee is not mandatory : each seller or manufacturer is free to offer it (or not) for the duration they want.

If you purchase a commercial guarantee, you can always implement the legal guarantees in case of a problem.


Telcos or sellers can offer to pay a premium to have your phone replaced in case of a breakdown or theft. This device is an insurance and not a commercial guarantee.

The seller or manufacturer is free to define the conditions under which his commercial guarantee will work.

Example :

The warranty may cover the cost of the parts, but not the cost of labor or the cost of moving the repairman. It can also exclude certain parts (for example, a phone battery) or certain failures.

All these conditions must obligatory be included in a warranty contract provided by the seller (or manufacturer) and signed by the customer.

The contract shall contain the following information:

  • Warranty content (which parts are covered,...) and excludes breakdowns or services
  • Information necessary for its implementation (place and conditions of repair of the defective product,...)
  • Price
  • Duration, geographical area covered (store where the product can be delivered abroad for repair or replacement)
  • Name and address of the seller or manufacturer
  • Reminder of seller's (or manufacturer's) obligation to comply with legal warranties (conformity and hidden defects) in addition to the commercial guarantee

If the trader does not comply with these provisions, the guarantee shall remain valid. Likewise, if any of this information is not present in the contract, the buyer can always implement these guarantees.

The duration of the commercial guarantee is freely fixed by the seller or the manufacturer.

It must be mentioned in the contract.

It can be free or paid for.

Free warranty

She can name herself manufacturer's warranty or manufacturer's warranty.

Guaranteed for a fee

She can name herself extension of warranty or else refurbished exchange guarantee.

This is a guarantee that is offered with the payment of a fee, and for which you must give your consent.

The seller may not consider that you accept certain options because you have not explicitly opposed them (for example, if the contract contains pre-ticked boxes). Thus, the seller cannot impose the mandatory subscription of an extension of warranty.

If you find that the contract contains terms that you did not subscribe to, you can ask the seller or manufacturer to refund you.

Proof of failure

You can have the purchased good repaired under the terms of the contract as long as the fault is defined in it.

Most of the time, you have to make a simple statement.

Purchase Entitlement

To qualify for the warranty, you must provide the seller or manufacturer with the (original) proof of the dated purchase.

This proof must prove that you have indeed purchased this property on such a date: delivery note, receipt, invoice,...

The seller or manufacturer may also provide you with a specific document to be used.

During repairs

In the case of repair of goods under commercial guarantee, any period of immobilization of the goods of at least 7 calendar days is in addition to the remaining term of the warranty.

Example :

If the seller keeps your TV for 8 days, your warranty that was due to end on September 6, 2021 will end on September 14, 2021.

Please note

the commercial guarantee contract sometimes provides for the provision of replacement goods during the period of detention of the goods (for example, a courtesy vehicle). However, this is not an obligation for the professional, you can not require this loan.

Formal notice

If the seller or manufacturer refuses to apply the terms of their warranty (repair or refund), you can issue a formal notice, that is, give them a period of time to comply with their obligations.

To do this, you must send a letter by registered mail with acknowledgement of receipt.

You can use the following letter template:

Instruct the seller to apply the commercial warranty for a device that often fails

Mediation or conciliation

If the dispute persists, you can choose to:

Seek justice

If mediation or conciliation has failed, you can go to court.

You can also ask for damages damage sustained as a result of the immobilization of the goods or damage to the product during repairs.

The competent court depends on the sums involved in the dispute.

  • For a case less than or equal to €10,000, it is the local court or the judicial court.
  • For a case greater than €10,000No, it's the court.

The commercial warranty has expired

You can always use legal warranties (conformity and hidden defects).

The commercial warranty has expired and legal warranties no longer apply

You can use the after sales service (after-sales service).

The VAS will repair the product without you being able to benefit from the rights related to the warranty in return for the payment of the service. The repair will therefore be paid for. You can ask for a quote.

The seller must provide you with the following information beforehand:

  • Contact details (name, address)
  • Description of service
  • Indicative schedule of the amounts of services invoiced and time limit for carrying out repairs

After-sales services must be the subject of a written contract given to the buyer.

When repair services are billed on a flat-rate basis, you must be notified in writing:

  • the origin of the failure,
  • the nature of the intervention,
  • and replaced parts and supplies.
