The National Audit Office’s 2019 modelling illustrated the enormity of the task and triggered a scramble for customs capacity that simply didn’t exist at the time.
Before Brexit, the customs intermediary market had been flat for years, offering little incentive for brokers to invest in staff or systems, especially as Brexit deadlines repeatedly shifted and political uncertainty persisted. As 2020 progressed and freight forwarders were unable to secure reliable customs support, many began building their own in‑house solutions. Salaries for staff with even modest customs experience surged, and companies repurposed workers from entirely unrelated professions, hairdressers, bar staff, warehouse operatives, accountants, putting them through accelerated customs training programmes in preparation for “day one,” whenever it might arrive.
When Brexit finally took effect, HMRC initially adopted a “flow over control” approach, prioritising the uninterrupted movement of goods over strict compliance. Freight moved, mistakes were tolerated, and freight forwarders’ new customs operations reaped significant financial rewards. An additional £40–£50 per consignment transformed their margins, turning customs services into a lucrative, if risky, revenue stream during 2021.
However, the boom quickly stabilised. Forwarders largely chose to process customs only for the shipments they handled themselves rather than pursuing standalone customs agency models. Meanwhile, established customs brokers, who had survived the chaotic early phase began reclaiming market share, targeting traders that had initially dispersed their declarations across multiple forwarders simply to keep goods flowing.
As a result, many forwarders face shrinking customs revenue and are shifting from growth to cost control, with some even offshoring their customs functions. Yet liabilities have hardened: the era of “just file the form” is over, and significant penalties have exposed weak practices and inexperienced staff.
Many customs clerks who were once in short supply are now openly seeking work.
For GB exports, forwarders are encouraged to retain control: the process is simpler, lower‑risk and operationally efficient. But for GB imports, where risk and complexity are higher, the message is clear: stop tying up resources on low‑value transactional work. Instead, collaborate with specialists and focus on value creation.
Finally, many multinational forwarders still rely on maritime‑style processes for EU–GB ro‑ro cargo. This, critics argue, is a fundamental mismatch: these fast‑moving, low‑duty flows more closely resemble parcel/e‑commerce traffic. Recasting them accordingly could reduce friction and prevent Brexit from being more cumbersome than necessary.
Five years after Brexit, the customs landscape continues to evolve. The companies that succeed may not be those doing the most declarations, but those redefining where the real value in customs expertise lies.
