An ETA is not a visa. It lets the holder travel to the UK, Jersey, Guernsey or the Isle of Man for visits of up to six months, as often as they like while it is valid, but it does not guarantee entry. Similar schemes include the US ESTA and the EU’s planned ETIAS.

How it came in

• ETAs were introduced in October 2023 and extended in stages. Eligible non-European visitors have needed one since 8 January 2025 and eligible Europeans since 2 April 2025.

• The rule was not strictly enforced during the roll-out. Since 25 February 2026 airlines have prevented passengers from boarding without an ETA, an eVisa or other valid documentation.

• The fee rose from £16 to £20 on 8 April 2026. There is no refund once someone has applied.

Who needs one

• Visitors of the 83 nationalities on the Home Office ETA list, including babies and children. One person can apply for others.

• Passengers changing planes who pass through UK border control. Those who stay airside do not need one.

• British and Irish citizens do not need one. Dual citizens who are British or Irish cannot get one and must prove their citizenship instead, for example with a British or Irish passport. People with a UK visa or permission to live, work or study in the UK do not need one either.

Why it matters for travel businesses

It matters to businesses that bring overseas visitors to the UK, such as a receptive tour operator. GOV.UK says most decisions arrive within a day but can take up to three working days. The Home Office recommends applying at least three working days before travel. GOV.UK also warns that other websites may charge more than the official service.
