UK Transit Visa: Airside, Landside and Transit Without a Visa

A UK layover can be airside, where the traveller does not pass UK border control, or landside, where the traveller enters the UK briefly to continue the journey. The required permission depends on the passport, the transfer and whether the traveller crosses the border. A Direct Airside Transit visa (DATV), a Visitor in Transit visa and transit without a visa are different routes. This guide summarizes GOV.UK and Home Office guidance checked on 28 October 2026.

Decide whether the connection is airside or landside

GOV.UK defines airside transit as leaving the UK without passing through border control. Landside transit means passing UK border control to enter the UK and leaving again within a short period. A traveller may need to collect baggage, change airports, check in again or use a terminal transfer that requires border control. Ask the airline whether the complete itinerary stays airside; a ticket itinerary alone may not show how the airport transfer works.

Check the current GOV.UK transit visa overview for the traveller’s nationality and circumstances. The Home Office carrier list identifies nationals subject to transit requirements and certain exemptions, but the live rules and case-specific facts control. The traveller also needs permission to enter the onward destination and any other country in the route.

For a temporary visit to see family or friends in the UK, see the separate UK Standard Visitor family-visit guide. Transit permission is for the journey onward, not for a family visit.

If the traveller stays airside: Direct Airside Transit visa

A visa national who changes flights in the UK without passing border control may need a Direct Airside Transit visa. GOV.UK lists exemptions, including a valid ETA, an EU Settlement Scheme family permit, a Home Office travel document, or a Standard or Marriage Visitor visa. Check the current exemption and carrier list for the exact traveller; do not infer that every visa or residence permit issued by another country is accepted.

GOV.UK says a traveller going to or from Ireland, the Channel Islands or the Isle of Man must apply for another type of visitor visa rather than relying on a DATV. An airside traveller does not need an ETA solely for transiting without passing UK border control, but the airline and destination’s document rules still apply.

The published DATV fee is £41.50 (the amount can vary slightly by application country). Apply online and follow the appointment instructions. GOV.UK says a decision usually takes three weeks, but this is an estimate rather than a guaranteed travel date.

If the traveller passes border control: Visitor in Transit

A Visitor in Transit visa may be needed when the traveller passes UK border control to continue to another country and will leave the UK within 48 hours. The applicant must genuinely be in transit to a destination outside the Common Travel Area, take a reasonable route, be able to leave within the permitted time and be assured entry to the destination. Work, study, medical treatment and public-fund access are not permitted under this transit route.

If the stay is longer than 48 hours, GOV.UK directs the traveller to check the Standard Visitor route instead. A traveller who holds an ETA or one of the listed existing permissions may not need a separate transit visa, but still has to satisfy the relevant entry rules. A transit visa does not authorize a UK visit for a different purpose.

The published Visitor in Transit fee is £74.50, subject to slight variation by application country. Apply online; the application may require a visa application centre appointment and biometric information. GOV.UK usually quotes a three-week decision time after applying, but processing can vary.

Understand transit without a visa (TWOV)

Some travellers may qualify for Transit Without Visa instead of obtaining a transit visa. Airside and landside conditions differ. The current carrier guidance says, for example, that an airside journey generally requires arrival and departure by air, a confirmed onward flight from the same airport on the same day and the correct destination documents. Landside TWOV has its own conditions, including a confirmed onward flight by 23:59 on the following day and specified visa or residence-document exemptions.

The carrier list contains detailed and frequently updated nationality and document conditions. A landside TWOV decision is made by an immigration officer at the UK border; eligibility is not a guaranteed entry right. Read the live carrier list and transit rules rather than treating one qualifying document as a blanket exemption.

Airside and landside TWOV are not interchangeable

The published airside concession generally requires the passenger to arrive and depart by air, leave from the same airport on a confirmed flight on the same day, and hold the correct documents for the destination. A traveller cannot use airside transit to reach Ireland or another place inside the Common Travel Area. The passenger must remain in the area where no UK border crossing occurs.

Landside TWOV has a different clock: the onward flight must depart by 23:59 on the day after arrival. The carrier list sets out specified qualifying documents and route conditions. Examples include certain valid visas for Australia, Canada, New Zealand or the United States, and certain common-format EEA/Swiss residence permits or category D visas. The accepted document, journey direction and evidence of entry to a country can matter; an electronic visa or residence record is not necessarily accepted unless it can be verified in the required way. Treat these as examples only and check the current list rather than assuming a visa from a named country is enough.

Even when a passenger appears to meet the concession, permission to enter is not automatic. The passenger must show the onward journey and destination documents, and an immigration officer decides whether to grant landside transit without a visa at the border. A carrier may refuse boarding if the required evidence cannot be established before departure. Anyone relying on TWOV should carry the original accepted document or the verification evidence specified by the live guidance.

When a connection changes after booking

A planned connection can stop being airside when a terminal transfer requires immigration control, the traveller must collect and recheck baggage, the onward carrier will not issue a boarding pass before arrival, or the passenger changes airports. Overnight airport arrangements and the final check-in time can also require entry to the UK. A missed flight, cancelled service or schedule change may push the onward departure outside a same-day airside condition or the TWOV next-day deadline.

Before paying for a separate-ticket itinerary, ask each airline how check-in and baggage will work at the transfer point and what happens if the incoming flight is delayed. The airline can describe its airport process, but only the current Home Office rules determine the visa requirement and Border Force decides a landside concession. Do not assume an airside visa remains sufficient if the travel plan now requires entering the UK; the passenger may need a different permission before boarding.

If the connection is routed to or from Ireland, the Channel Islands or the Isle of Man, confirm both countries’ requirements independently. A UK transit permission does not grant admission to Ireland and an Irish visa does not itself establish permission for every UK transit route. The CTA exceptions are document- and direction-specific, so use the current GOV.UK pages for the exact Irish biometric endorsement and travel direction.

Ireland and the Common Travel Area

The Common Travel Area includes the UK, Ireland, the Channel Islands and the Isle of Man. Home Office transit guidance treats the destination for a transit visitor as a country outside the CTA. If the trip is to or from Ireland, or another CTA destination, GOV.UK says the traveller may need a visitor visa rather than a transit visa; an Irish biometric visa endorsed BC or BC BIVS has specific exceptions. Check the current route page for the exact direction of travel and endorsement.

Do not assume that permission to transit the UK grants permission to enter Ireland, or vice versa. Check each country’s rules independently, including whether a UK or Irish border crossing occurs during the connection.

Prepare the application and travel documents

GOV.UK says a transit application may require a valid passport or travel document, evidence that the traveller can enter the destination country, and proof of a confirmed onward journey. The application may require fingerprints and a photograph at a visa application centre. Follow the route-specific online application and current instructions for the country where applying.

The documents should support a route that is reasonable and short. For a landside application, be ready to show when the traveller arrives, when the confirmed flight leaves, and that the destination country will admit them. If the traveller is not a national or resident of the destination, the application may need to explain the reason for travel and where they will stay. A return or onward booking is evidence of the plan, not a guarantee that the applicant meets the other visitor requirements.

Book the visa appointment with enough time to provide biometrics and have the passport available for the decision. GOV.UK’s usual three-week estimate is not a promise; some visa application centres offer faster services, but availability depends on the location. Do not travel based only on an appointment confirmation or application receipt. If the itinerary requires an immediate border crossing, the traveller needs the required permission in hand before travel.

Where the traveller already holds a valid UK permission that is listed as exempt from a separate transit visa, check that it covers the date and purpose of travel. A document can remove the need for one transit category while still not authorizing every activity or a longer UK stay. If the passenger plans to visit family, work, study or remain more than 48 hours, use the appropriate visa route instead of treating the connection as transit.

Before departure, keep the passport, transit permission or exemption evidence, onward itinerary, destination visa or residence permission and relevant connecting-flight details available for the carrier. Ask the airline about terminal changes, baggage and border control before purchasing a connection that depends on remaining airside.

A practical pre-flight sequence

This is a route overview, not an immigration eligibility decision or legal advice. It does not determine an individual’s nationality-based visa requirement, whether a document qualifies for an exemption, or whether Border Force will permit entry. Confirm the current GOV.UK guidance, carrier requirements and destination rules before travel.
