Is an A1 FDES published in 2022 still valid in 2026?

421 questions from 58 articles available in English.

No, not since 1 July 2026. Since 1 November 2022, only the EN 15804+A2 version has been accepted for a new or renewed sheet. At the request of the DHUP (the French housing, urban planning and landscapes directorate), INIES postponed the withdrawal of A1 sheets verified in 2021 and 2022 to that date (those verified in 2020 were withdrawn on 1 January 2026). As a result, renewing A1 sheets as A2 is a catalogue priority for any manufacturer that wants to stay competitive on tenders after 2025.
