Will an ATA Carnet remove the need to complete customs declarations for temporary exports?

The ATA Carnet system is operated by HMRC. This is a process that allows you to complete your customs declarations a single time and then can use the Carnet as confirmation that your movements will be temporary and therefore not incur the potential for a tariff when you go to the EU. This will remove the need for customs declarations for as long as the Carnet is valid. You are advised to check with HMRC on the precise details that accompany the Carnet.
