For all matches of the qualifying phase and the play-offs, balls must comply with the IFAB Laws of the Game as well as with the UEFA Equipment Regulations. The home club must provide the visiting club with match balls of excellent quality for its training session on the day before the match as well as for warming up before the match. These match balls must be the same as those used for the match.
The applicable official UEFA Europa Conference League match ball determined by the UEFA administration must be used for all matches from the group stage and for the official training sessions before these matches.
The use of two-sided substitution boards (preferably electronic) is compulsory.
For each match in the qualifying phase and play-offs, the home club must ensure that two substitution boards are available.
Goal-line technology (GLT) may be used in accordance with the IFAB Laws of the Game and the FIFA Quality Programme for GLT Testing Manual for the purpose of verifying whether a goal has been scored to support the referee’s decision. That decision remains under the sole discretion of the referee and is final. UEFA may decide to use GLT in selected matches.
A failure of the GLT system may in no way prejudice the decision of the referee. If necessary, for example in case of a system failure, matches will take place or continue without the use of GLT.
Pre-installed and certified GLT systems may be used in the qualifying phase and play-offs, subject to UEFA’s approval and the visiting club’s consent. The host club remains fully responsible for the operation of the system and bears all the associated costs.
As of the group stage, pre-installed and certified GLT systems may be used, subject to UEFA's approval. If such a system is used, it needs to be used for all matches played by the club in the competition. The host club remains fully responsible for the operation of the system and bears all the associated costs.
