What is UK261 — the UK’s retained flight-compensation framework after Brexit, how it mirrors and differs from EU261, and when to check CAA guidance for your route.

Key takeaways

What is UK261?

Link to this answer

UK261 is the informal name for the United Kingdom’s retained passenger-rights rules that mirror much of EU261 — care during long disruptions and standardised compensation for certain delays, cancellations and denied boarding on qualifying UK-related flights.Keep reading: What Is EU261? · EU261 Compensation Complete Rules 2026: Delays, Cancellations & Care

After Brexit the UK kept a parallel framework rather than leaving passengers without delay rights. Eligibility still turns on route, operating carrier and delay at final arrival. Many travellers shorthand both regimes as “261”; the governing text and enforcement body (CAA versus EU national bodies) differ. CAA guidance for your exact airport pair and airline.

If your itinerary mixes UK and EU sectors, you may need to decide which frame fits each claim. Start with what is EU261 and the long-form EU261 complete rules for mechanics that still rhyme with UK practice, then confirm UK-specific notes on the CAA site.

UK enforcement language and complaint routes differ from EU national bodies even when the cash bands look familiar. If an airline replies with an EU261 template on a UK-departure claim, answer with the UK frame and your booking facts. Keep pounds-and-pence receipts for meals and hotels; care reimbursement is easier to evidence than a disputed extraordinary-circumstances email thread.

When should you think UK261 instead of EU261?

When your claim centres on a UK departure or a UK-enforcement path — for example a delayed flight leaving Heathrow — even if the airline also operates in the EU.

Example: Manchester–Dubai on a non-EU carrier departs the UK and is delayed into the compensation territory under UK rules; you document times and file with the airline, escalating via UK processes if needed. An EU carrier flight Paris–Manchester may point back to EU261 instead. Codeshare operating-carrier checks still apply — codeshare.

Denied boarding and oversales: denied boarding compensation, overbooking.

How do you file a UK261 claim?

Write to the operating airline citing UK261, state your flight, arrival delay and the fixed amount owed (GBP 220–520), attach boarding passes, and escalate to the CAA-approved dispute scheme or small-claims court if the airline refuses or stalls.

UK261 is Britain’s post-Brexit copy of EU261: compensation of GBP 220, 350 or 520 by distance and delay length for UK departures on any carrier, and arrivals on UK or EU carriers. The thresholds mirror the European original — three hours’ arrival delay, short-notice cancellation, or denied boarding — and the same “extraordinary circumstances” defence applies to weather and air-traffic control, but not routine technical problems or crew shortages.

The process is identical in spirit to the EU version: claim in writing to the operating carrier with evidence, request the statutory amount in pounds, and refuse vouchers unless they suit you. UK airlines must belong to an alternative dispute resolution scheme or answer to the Civil Aviation Authority, and both routes are free to passengers. Small-claims court in England and Wales handles these cases efficiently, with a limitation period of six years.

Travellers on itineraries touching both systems should check which regime pays more for their disruption — the rules overlap on some routings but you claim once. Our UK261 vs EU261 answer page maps the borderline cases, and EU261 complete rules covers the continental mirror.
