What Is UK261 and How Does It Work After Brexit?

UK261 is the law that protects your rights as an air passenger when something goes wrong with your flight. Whether your departure is delayed for hours, your flight is cancelled at short notice, or you're turned away at the gate on an overbooked aircraft, UK261 sets out exactly what you're owed and what the airline must do.

Before Brexit, British travellers were protected by EU Regulation 261/2004 — a European law that gave passengers across the continent the right to claim financial compensation and practical support during flight disruptions. When the UK left the EU, that protection did not disappear. Instead, the UK Government incorporated the regulation into domestic law, creating what is now known as UK261.

This guide explains clearly what UK261 covers, how it differs from its EU equivalent, what compensation you're entitled to, and how to start a claim if your flight is affected.

What Is UK261?

UK261 is the commonly used name for the Air Passenger Rights and Air Travel Organisers' Licensing (Amendment) (EU Exit) Regulations 2019. It became part of UK domestic law at the end of the Brexit transition period on 1 January 2021.

In practical terms, UK261 mirrors EU Regulation 261/2004 almost identically. The rights passengers had before Brexit — to compensation, to care and assistance, to a refund or rebooking — remain in place. The most visible change is that compensation is now paid in pounds sterling rather than euros.

UK261 is enforced in the UK by the Civil Aviation Authority (CAA), which acts as the regulatory body responsible for ensuring airlines comply with the law. If an airline refuses to pay a valid claim, passengers can escalate to the CAA or pursue the matter through UK courts.

Which flights does UK261 cover?

UK261 does not cover every flight taken by a British traveller. Coverage depends on the direction of travel and the airline operating the flight. Here's a straightforward breakdown:

The key principle is this: if your flight departs from the UK, you are protected regardless of which airline you're flying with. If you're flying into the UK, coverage depends on whether the carrier is based in the UK or the EU.

It's also worth noting that UK261 can sometimes apply alongside EU261 on the same journey — for example, on a flight between a UK airport and an EU destination operated by a UK carrier. In that scenario, you cannot claim twice, but you can choose whichever regulation is more favourable to your situation.

What are you entitled to under UK261?

Air passenger rights under UK261 fall into three main categories: financial compensation, the right to care and assistance, and the right to a refund or rebooking. Each applies in different circumstances.

Financial compensation for flight delays

Under UK261, you are entitled to flight delay compensation when your flight arrives at its destination three or more hours later than scheduled — and when the delay was the airline's responsibility. The amount you can claim is fixed by law and based on the distance of the flight:

These amounts apply per passenger, so families travelling together can multiply the figures accordingly. The compensation is not linked to how much you paid for your ticket — a passenger in economy class has exactly the same entitlement as one in business class.

Right to care and assistance

Even before the three-hour mark, UK261 gives you the right to care and assistance from the airline while you wait. This is separate from and in addition to any financial compensation you may be entitled to.

The airline must provide you with:

•        Meals and refreshments reasonable for the length of your wait

•        Hotel accommodation if an overnight stay becomes necessary

•        Transport between the airport and your hotel

•        Access to communication — either phone calls or reimbursement for reasonable communication costs

These entitlements kick in after two hours for short-haul flights (under 1,500 km), three hours for medium-haul (1,500–3,500 km), and four hours for long-haul flights (over 3,500 km). Importantly, this right to care applies regardless of the cause of the delay — even if the disruption is down to extraordinary circumstances, the airline must still look after you at the airport.

Refund or rebooking for cancellations and denied boarding

If your flight is cancelled with less than 14 days' notice, or you are denied boarding because the flight is overbooked, you are entitled to choose between:

•        A full refund of your ticket cost

•        An alternative flight to your destination at the earliest possible opportunity

•        Rebooking on a later flight at a date and time of your choice

Choosing one of these options does not remove your right to claim financial compensation. The two entitlements are separate — if you accept a replacement flight but still arrive three or more hours late, you can still claim the appropriate compensation amount on top.

What are extraordinary circumstances under UK261?

Airlines are not required to pay financial compensation if they can demonstrate that the disruption was caused by an "extraordinary circumstance" — an event outside their control that could not have been avoided even if all reasonable measures had been taken.

Common examples of extraordinary circumstances include:

•        Severe and unexpected weather conditions such as storms or blizzards

•        Air traffic control restrictions or industrial action by ATC staff

•        Security threats or acts of terrorism

•        Political instability or restrictions imposed by government authorities

However, it's important to understand what does not qualify as an extraordinary circumstance. These situations are within the airline's control and give you a valid right to compensation:

•        Technical faults with the aircraft, unless caused by a hidden manufacturing defect

•        Airline staff sickness, including pilots and cabin crew

•        Industrial action by the airline's own employees

•        Overbooking and resulting denied boarding

Airlines sometimes attempt to use extraordinary circumstances as a blanket defence when the real cause of a disruption is something they could and should have managed. If your claim has been rejected on these grounds, it is worth getting a professional assessment before accepting the decision.

UK261 vs EU261: what changed after Brexit?

For most passengers, the practical difference between UK261 and EU261 is minimal. The rights are equivalent, and the situations in which they apply are broadly the same. The main changes are:

•        Currency: Compensation under UK261 is paid in pounds sterling (£220, £350, or £520). EU261 amounts are in euros (€250, €400, or €600). Due to exchange rate fluctuations, the pound amounts are sometimes slightly lower in value.

•        Jurisdiction: UK261 claims are handled by UK courts and the Civil Aviation Authority. EU261 claims fall under the jurisdiction of EU member states and their designated enforcement bodies.

•        Which law applies: On routes between the UK and EU, both regulations may technically apply. Passengers can choose the more advantageous regulation, but cannot claim under both simultaneously.

The underlying protections — compensation levels by distance, the right to care, the 14-day cancellation rule, the six-year claim window — are all consistent between the two regimes. For the vast majority of UK passengers travelling to and from European destinations, air passenger rights UK travellers enjoy remain as robust as they were before Brexit.

How to make a UK261 claim

Making a claim under UK261 is a straightforward process, though airlines do not always make it easy. Here's the typical path:

Step 1 – Check your eligibility

Before you do anything, confirm that your flight and the circumstances of your disruption are covered by UK261. You need to verify: the route and airline, the length of your delay (at arrival, not departure), and whether the cause of the disruption rules out compensation.

Step 2 – Submit a claim to the airline

Contact the airline's customer service department in writing, stating your flight details, the nature of the disruption, and the amount of compensation you believe you are owed. Keep a record of all correspondence.

Airlines must respond, though there is no fixed statutory deadline for them to do so. Many will come back within 30 days. Others will delay, deny, or offer a lower settlement than you're entitled to.

Step 3 – Escalate if necessary

If your claim is rejected or ignored, you can report it to the Civil Aviation Authority (CAA) or take the matter to a UK court. Many passengers at this stage choose to use a specialist claims service to take over the process.

At Flight Delay Claim, we handle the entire process on your behalf. You can start your flight delay claim online in a matter of minutes, and we work on a no-win, no-fee basis — so there's no financial risk to you.

Time limits for UK261 claims

In England, Wales, and Northern Ireland, you have six years from the date of your disrupted flight to make a claim. In Scotland, the limit is five years. This is one of the most generous claim windows in the world, meaning you may still be able to pursue compensation for flights that were disrupted several years ago.

Which UK airports see the most delays?

Delays and cancellations are not evenly distributed across UK airports. Some airports — and certain routes — consistently see higher rates of disruption than others, for a range of reasons including congestion, infrastructure, and the airlines that operate there.

Understanding which airports are most affected can help travellers plan ahead and know when they're more likely to need to exercise their air passenger rights UK law provides. Our guide to the worst UK airports for flight delays breaks down the data in full and explains what it means for your chances of a smooth departure.

Summary: your UK261 rights at a glance

UK261 ensures that British air passengers retain the same protections they had before Brexit. Whether your flight is delayed, cancelled, or you're refused boarding, the law sets clear entitlements:

•        Up to £520 compensation per passenger for significant delays and cancellations

•        Food, refreshments, and accommodation while you wait at the airport

•        A full refund or alternative flight if your journey is cancelled

•        A six-year window to make a claim (five years in Scotland)

The regulation applies to all flights departing from UK airports, and to flights arriving in the UK on UK or EU carriers. The compensation amount is fixed by law and has nothing to do with the price you paid for your ticket.

Airlines are not always quick to pay out valid claims, but the law is firmly on your side. If you've experienced a disrupted flight and haven't yet claimed, the chances are you're owed money — and the process of recovering it is simpler than many people think.

Find out how much you're owed

If your flight was delayed, cancelled, or overbooked, UK261 may entitle you to compensation of up to £520 per person. The best first step is to check your specific flight.
