HMRC opened the consultation in June 2026. It proposes that agents, brokers, freight forwarders and express operators who submit customs declarations for traders must register. Registration would apply across the UK, to imports and exports.
The proposed minimum standards mirror those for tax advisers. They include up-to-date tax affairs, no relevant unspent convictions, no disqualification as a company director and no history of serious customs non-compliance. HMRC would run automated checks at registration and afterwards.
Enforcement would start with guidance and warnings, and could escalate to suspension, financial penalties and, as a last resort, removal of the ability to submit declarations. HMRC says 99% of traders rely solely on an intermediary to declare their trade. The policy is not final.
