The Home Office has set 20 March 2026 for the next stage of carrier liability: fines will extend to passengers who arrive without a required Electronic Travel Authorisation (ETA). For airlines and ferry operators, this moves the ETA regime from policy to balance sheet, with penalties landing where pre‑departure checks fail.

Section 76 of the Nationality and Borders Act 2022 amends section 40 of the Immigration and Asylum Act 1999 so that carrier charges also apply where a traveller lacks the appropriate digital permission to travel, including an ETA. The Explanatory Notes are explicit that carriers are expected to confirm permission to travel before boarding or risk a civil penalty. (legislation.gov.uk)

This sits alongside the wider rollout of ETAs. Ministers say the scheme is now universal for eligible non‑visa nationals, with more than 19.6 million ETAs granted up to September 2025, and they have told carriers to check permissions before travel. Enforcement messaging to operators stepped up from 25 February 2026. (questions-statements.parliament.uk)

Financially, the reference point remains the section 40 charge: £2,000 per passenger carried without the right documents or permission. The latest Border Force guidance confirms the amount and clarifies that liability covers owners, agents or operators of a ship or aircraft. It also reminds operators that ‘no document’ cases can be raised via CCTV linkage. (gov.uk)

Operationally, this becomes a digital check as much as a document check. Where permission is held only in digital form, carriers should rely on interactive Home Office messaging: a ‘0A’ board response is acceptable evidence to carry; ‘0B/0Z’ indicate further checks. Where a passenger presents online immigration status via ‘View and Prove’, staff should verify using the GOV.UK checker. Build these steps into DCS and kiosk flows to avoid manual workarounds. (gov.uk)

Front‑line runbooks need tightening before go‑live. Gate and port teams should have clear escalation to the 24/7 Carrier Support Hub, plus a fallback when interactive messaging times out. Carriers should also refresh customer‑handling scripts for refusals to board where no valid ETA or other permission is evident, to reduce on‑stand disruption. The guidance confirms the Hub’s remit and that Border Force will raise a charge if advice is ignored and the passenger is inadmissible. (gov.uk)

There is some relief for operators that invest in controls. Approved Gate Check (AGC) status means Border Force will normally waive charges for ‘no document’ or certain mutilated‑document arrivals from accredited ports and grant up to two ‘technical’ waivers per route per quarter. For finance teams, that can blunt tail‑risk. For example, three chargeable misses a month equates to £72,000 a year before disruption costs; AGC waivers can materially offset that exposure if standards are maintained. (gov.uk)

Ferry operators face practical challenges where foot passengers board close to departure and connectivity is variable. The priority is to shift checks upstream into booking and pre‑check‑in, then re‑validate at the gate using the same interactive permission messages. For rail, while section 40 charges focus on ships and aircraft, cross‑border train operators remain bound by the Authority to Carry regime and the ETA requirement, so airline‑grade pre‑departure controls still apply in practice. (gov.uk)

Disputes and cash‑flow matter too. Border Force sets out a formal path for representations and objections to the Carriers Liaison Section, with a defined window to contest a demand. Charges are recoverable in court as a civil debt, and monthly statements reconcile credits where waivers or errors arise. Build these time limits into finance controls so objections aren’t missed. (gov.uk)

The window is short. With 20 March 2026 approaching, carriers should complete DCS changes, test interactive messaging at scale, retrain third‑party handlers, and audit high‑risk routes. The policy intent is clear: UK permission to travel must be checked before boarding, and if that check fails, the bill moves from the passenger to the operator. (legislation.gov.uk)
