Travellers transiting through the United Kingdom may need a UK Transit Visa, depending on their nationality and travel circumstances. However, the UK does not issue transit visas on arrival. All UK transit visas must be applied for in advance before you travel. This rule applies to all airports, including Heathrow, Gatwick, and Manchester, and ensures compliance with UK Border Force entry requirements.
When You Need a UK Transit Visa
The type of transit visa you need depends on whether you will pass through the UK border during your connection.
- Direct Airside Transit Visa (DATV): Required if you will not pass through UK border control and will stay in the international transit area for your onward flight.
- Visitor in Transit Visa: Required if you plan to pass through border control, change airports, stay overnight, or if your connecting flight is more than 24 hours after arrival.
Check whether your nationality is exempt using official Home Office guidance, or review our related resources:

Applying for a UK Transit Visa
1) Apply Before You Travel
You cannot obtain a UK transit visa upon arrival. All applications must be completed online and submitted before departure. Once submitted, you will need to provide biometrics and supporting documentation. See the guide on UK Visa Application Processing Centres 2025 for details.
2) Documents You Will Need
Supporting evidence typically includes:
- A valid passport or travel document
- Evidence of your confirmed onward flight
- A valid visa or residence permit for your final destination (if required)
- Proof of sufficient funds during your transit stay
For complete document upload instructions, review UK Visa Supporting Documents Digital Upload Guide.
3) Application Fees and Processing Time
Transit visa fees and processing times vary depending on the location. For updated information, see UK Visa Fees 2025. Most applications are processed within two to three weeks.
Common Misunderstandings
- “I can get a visa at the airport.” – False. UK transit visas cannot be issued upon arrival.
- “I’m only changing flights, so I don’t need one.” – Some nationalities still require a Direct Airside Transit Visa even if remaining airside.
- “I have a valid US or Schengen visa, so I’m exempt.” – Exemptions exist but only apply under specific conditions. Always verify through official Home Office guidance or consult an immigration advisor.
What Happens If You Don’t Have the Right Visa?
If you arrive in the UK without the required transit visa, you may be refused boarding by your airline or refused entry by UK Border Force. To avoid travel disruption, always apply several weeks in advance and ensure your documents match your flight details.
