Brexit changed the paperwork for British travellers, and years on, people are still getting caught out. If you’re asking what documents you need to travel to Europe after Brexit, the short answer is: a passport with enough validity, the right to enter under visa-free rules, travel insurance with health cover, and — from 2026 — a new ETIAS authorisation. Here’s the full checklist, explained properly.

Your passport: the validity rules that catch people out

This is the big one. Your passport must now meet two conditions for most EU countries (plus Iceland, Norway, Switzerland and Liechtenstein):

• Issued less than 10 years before your date of entry. Not the expiry date — the issue date. Older UK passports sometimes had up to 9 months of extra validity added, which the EU no longer recognises.
• Valid for at least 3 months after the day you plan to leave.

Example: if you enter France on 1 July 2026 and leave on 14 July, your passport must have been issued after 1 July 2016 and expire after 14 October 2026. Check both dates now — thousands of Brits have been turned away at airports over this. If yours doesn’t comply, see our guide to applying for a passport renewal in the UK.

Children need their own passports too, and the same rules apply — child passports are only valid for five years, so check the issue date carefully.

ETIAS: the new travel authorisation

The EU’s European Travel Information and Authorisation System (ETIAS) is now required for visa-exempt visitors including Brits. It’s not a visa — it’s a pre-travel authorisation similar to America’s ESTA:

• Apply online before you travel (approval is usually quick but can take longer)
• It costs a small fee (around €20) for adults; free for under-18s and over-70s
• It’s valid for three years or until your passport expires
• You need it for every trip — but one authorisation covers multiple trips

Apply at least a few weeks before departure. Airlines can deny boarding if you don’t have it, and “I didn’t know” won’t help at the gate. Check the current status on the official EU ETIAS site — rules and timelines have shifted, so verify before every trip.

How long you can stay: the 90/180 rule

As a UK citizen you can stay in the Schengen area visa-free for 90 days in any 180-day period. This is cumulative across all Schengen countries — 30 days in Spain plus 30 in France plus 30 in Italy uses your full allowance. Overstay and you risk fines, deportation and future entry bans. If you’re planning a longer stay (a sabbatical, a second home), you’ll need a proper visa from the relevant country.

Health cover: your EHIC is (mostly) history

The old EHIC has been replaced by the UK Global Health Insurance Card (GHIC) for most people. It’s free from the NHS website — never pay a third-party site for one. The GHIC gives you access to state healthcare in EU countries at the same cost as locals.

But — and this is important — the GHIC is not a substitute for travel insurance. It doesn’t cover mountain rescue, repatriation, or private treatment, and some countries’ state systems still charge. Proper travel insurance remains essential. Declare any medical conditions honestly; an undeclared condition can void the whole policy.

Driving in Europe after Brexit

Taking your car or hiring one? You’ll need:

• A UK driving licence — the photocard is enough for most EU countries for short visits
• A UK sticker on your car (the old GB sticker is no longer valid)
• Your V5C logbook if taking your own car
• A green card from your insurer as proof of insurance — check whether your insurer still issues them; many now cover EU driving automatically for a set number of days
• Country-specific kit — France requires a breathalyser (rarely enforced but technically required), high-vis jackets and a warning triangle; Spain requires two triangles

Taking pets to Europe

Pet passports issued in the UK are no longer valid in the EU. Dogs, cats and ferrets now need an Animal Health Certificate from your vet, issued no more than 10 days before travel, for each trip. They must be microchipped and vaccinated against rabies. The certificate costs £100–£200 from most vets, so factor it into your holiday spending money. Plan ahead — vets get booked up in summer.

Other documents worth carrying

• Travel insurance policy details — on your phone and a printed copy
• Accommodation confirmations — border officers occasionally ask for proof of where you’re staying
• Return travel booking — proof you intend to leave within 90 days
• European breakdown cover if driving
• Copies of everything — photograph every document and store the photos securely online. If you lose your passport abroad, having copies massively speeds up the replacement process

Special cases

Ireland is different — the Common Travel Area means no passport is technically required for British citizens, though airlines and ferry companies will still ask for photo ID. Cruises stopping at multiple EU ports still count towards your 90 days. And if you have an EU passport through dual nationality, use it — it bypasses all of this.

Ireland and non-EU Europe: the exceptions

Ireland is the big exception. Under the Common Travel Area, British citizens can travel to Ireland without a passport — though in practice airlines and ferry operators require photo ID, and carrying your passport is strongly recommended. The ETIAS, 90/180 rule and Schengen requirements don’t apply.

For non-EU European countries, check individually: Norway, Iceland and Switzerland follow Schengen-style rules (90/180, ETIAS when it applies). Turkey requires no visa for short tourist visits but has its own entry rules. Always check the GOV.UK foreign travel advice for your specific destination — “Europe” isn’t one set of rules anymore, and assuming otherwise is how people get turned away at borders.

The takeaway

The documents you need for Europe after Brexit are: a passport meeting the 10-year/3-month rules, ETIAS authorisation, a GHIC plus proper travel insurance, and the right extras if you’re driving or taking pets. Check everything at least a month before you fly — border control has no sense of humour about paperwork, and the queue behind you certainly won’t.
