UK Transit Visa Guide: Do You Need One to Change Flights in the UK?
In this guide
Quick answer: You might need a UK transit visa if you pass through the UK on the way to another country. There are two types: the Direct Airside Transit visa (DATV) if you change flights in the UK without going through UK border control, and the Visitor in Transit visa (VTV) if you go through UK border control but leave within 48 hours. You do not need a transit visa if you hold an ETA, a Standard Visitor visa and certain other documents.
A long-haul trip with a stopover in London can turn into a visa problem at the check-in desk. The rules depend on your nationality and whether you will step out of the airport’s secure area, and it is the airline’s check at departure that catches most people. Here is what GOV.UK says, in plain language, and how to find out which category you fall into.
Do you need a UK transit visa?
GOV.UK says you might need a visa to pass through the UK in transit, and that you should check your eligibility before applying. You do not need one if you hold:
- an Electronic Travel Authorisation (ETA),
- an EU Settlement Scheme family permit,
- a Home Office travel document,
- a Standard Visitor visa, or
- a Marriage Visitor visa.
If an ETA might apply to your nationality, read our UK ETA guide.
What are the two types of UK transit visa?
| Visa | Use it when |
|---|---|
| Direct Airside Transit visa (DATV) | You change flights in the UK without going through UK border control |
| Visitor in Transit visa (VTV) | You go through UK border control and leave the UK within 48 hours |
Your airline can tell you whether your journey will take you through border control. This matters: a flight change that requires you to collect baggage and re-check it usually means leaving the airside area, but check with the airline rather than assuming.
When do you need a Standard Visitor visa instead?
GOV.UK says you need a Standard Visitor visa if you must stay more than 48 hours, or if you need to pass through the UK frequently over a period of more than six months. ETA holders do not need one in this case. See our UK Standard Visitor visa guide for what that visa allows.
What about cost and validity?
The transit visa page we reviewed does not state the cost or how long each visa lasts. DATV and VTV each have their own pages. Check those pages for current fees before you apply, and do not rely on third-party websites for the price.
A quick decision path
- Do you hold an ETA, a Standard Visitor visa or one of the other listed documents? Then you do not need a transit visa.
- Are you staying airside and changing flights only? You may need a DATV.
- Will you go through border control and leave within 48 hours? You may need a VTV.
- Staying longer than 48 hours or transiting often over six months? Look at a Standard Visitor visa.
- Ask your airline if you are unsure which situation applies.
Common mistakes
- Assuming a short stopover never needs a visa.
- Booking separate tickets that force you through border control.
- Using unofficial visa websites that charge extra. Apply only through GOV.UK. See how to avoid visa scams.
Frequently asked questions
Is the DATV the same as a visit visa?
No. A DATV is only for changing flights without passing through UK border control.
Can I leave the airport on a transit visa?
With a VTV you go through border control and must leave within 48 hours. A DATV does not let you pass through border control.
Does an ETA replace a transit visa?
GOV.UK says you do not need a transit visa if you hold an ETA.
Key takeaways
- DATV: airside only. VTV: through border control, leaving within 48 hours.
- No transit visa is needed with an ETA, Standard Visitor visa and the other listed documents.
- More than 48 hours or frequent transits means a Standard Visitor visa.
