UK ETA: carrier liability begins 20 March 2026

Mark the calendar: on Friday 20 March 2026, a new rule switches on. Airlines, ferries and other transport operators will be legally responsible if they carry passengers to the UK who should have an Electronic Travel Authorisation (ETA) but don’t. The change is set out in the Nationality and Borders Act 2022 (Commencement No. 9) Regulations 2026 (SI 2026/165), published on legislation.gov.uk after being made on 25 February 2026.

If you’re hearing about ETAs for the first time, here’s the key timing. The Home Office has said the UK’s ‘permission to travel’ rule is being actively enforced from 25 February 2026: visitors from 85 visa‑free countries must hold an ETA before they board. Carriers are expected to check this status before departure. (gov.uk)

Today’s commencement flips on Section 76 of the Nationality and Borders Act 2022. That section extends the long‑standing carriers’ liability scheme so it also covers ETAs. In plain English: if a required ETA isn’t in place and a passenger is still carried to the UK, a civil penalty can follow. (legislation.gov.uk)

Section 76 works by amending section 40 of the Immigration and Asylum Act 1999, the law that already allowed charges when a passenger arrived without proper documents like a visa. It updates the test so ‘permission to travel’ can be digital and includes a built‑in ‘statutory excuse’ when a carrier genuinely can’t access Home Office systems to verify permission despite doing the right checks. (legislation.gov.uk)

What counts as a ‘carrier’? In practice we’re talking about airlines and ferry operators bringing people to the UK. Many already collect Advance Passenger Information and run document checks at check‑in and the gate, but the legal onus after 20 March is clearer: the ETA, where required, needs to be in place before travel. The Home Office has been explicit that carriers will be checking people before they travel. (gov.uk)

Who actually needs an ETA? Not British or Irish citizens. But if you hold dual nationality, the government advises you travel on a British or Irish passport (or hold a certificate of entitlement) from 25 February 2026. ETAs are not issued to British citizens. If you’re visiting on a non‑British, non‑Irish passport from a visa‑free country, apply via the official app; it costs £16 and most decisions are quick, though you should allow up to three working days. (gov.uk)

Why are there two dates? Acts of Parliament don’t usually start all at once. Ministers make separate ‘commencement regulations’ that switch on specific sections on specific days. The 25 February date marked the traveller‑side rule being enforced at the border. The 20 March date switches on the penalty lever that formalises carriers’ responsibility. That short gap gives operators time to finish updates to digital check‑in and staff training.

If you work for an airline or ferry, treat this like a safety drill. Build ETA prompts into booking and check‑in, make the messaging clear for passengers who think ‘visa‑free’ means ‘no action’, and log your checks. That audit trail matters if you need to rely on the statutory excuse because a Home Office system was unavailable and you acted reasonably. (legislation.gov.uk)

For travellers and families, the lesson is simple. Think of the ETA like the UK’s version of other countries’ pre‑travel authorisations. Plan ahead, use the official app, and don’t leave it to the airport queue. If you have dual nationality, renew the right passport in good time or carry the correct proof, because carriers will refuse boarding without permission to travel. (gov.uk)

One last civics note. The regulation is signed by Mike Tapp, the Minister for Migration and Citizenship at the Home Office, and applies across England, Wales, Scotland and Northern Ireland. Keeping an eye on who signs, what gets switched on, and when, helps us all understand how policy becomes practice at the border. (gov.uk)
