Focus phrase: Transit visa for a UK connecting flight.
Whether you need a UK transit visa depends on your nationality, travel route, and whether you will pass through UK border control during your connection. The UK operates two main types of transit visas: the Direct Airside Transit Visa (DATV) and the Visitor in Transit Visa. This guide explains who needs a visa, how to apply, and what documents you’ll need when connecting through the UK in 2025.
When You Need a UK Transit Visa
If you’re travelling through a UK airport on your way to another country, you may require a transit visa unless you qualify for a visa exemption. You will typically need a transit visa if:
- You are a national of a country that requires a visa to enter the UK, even if you do not plan to leave the airport.
- Your layover is longer than 24 hours or requires you to change terminals or airports.
- You plan to pass through UK Border Control during your transit.
Travellers from visa-exempt countries (including most European Union, EEA, and select Commonwealth countries) usually do not need a transit visa, provided they continue their journey within 24 hours and remain airside.

Types of UK Transit Visas
The UK offers two visa types depending on whether you pass through immigration control:
- Direct Airside Transit Visa (DATV): For travellers who remain within the international transit area and do not pass through UK Border Control.
- Visitor in Transit Visa: For travellers who must pass through UK Border Control, change airports, or stay overnight for a connecting flight.
It’s important to determine which type applies to your travel plans before submitting your application. For example, passengers connecting between Heathrow and Gatwick will need a Visitor in Transit Visa because this route requires exiting one airport and entering another.
How to Apply for a UK Transit Visa
Applications are made online via the UK Government’s official immigration website. Once submitted, applicants must attend a biometric appointment at one of the UK Visa Application Processing Centres.
To apply, you will need to provide:
- A valid passport or travel document
- Confirmed flight booking and travel itinerary
- Visa or residence permit for your final destination (if applicable)
- Evidence of sufficient funds to support yourself during transit
For details on document preparation, review UK Visa Supporting Documents Digital Upload Guide.
Processing Times and Fees
Most UK transit visa applications are processed within three weeks. If you need to travel urgently, you can use the UK Visa Priority Service for faster processing. Current fees and health surcharge exemptions are listed on UK Visa Fees 2025.
Common Exemptions
You may not need a UK transit visa if you:
- Hold a valid visa for the USA, Canada, Australia, or New Zealand and are travelling to or from one of these countries.
- Hold a residence permit issued by an EU or EEA member state.
- Have a valid flight booking and will remain airside for your entire connection (under 24 hours).
To verify your status, use the official Home Office transit eligibility checker or review our related article, Can I Transit the UK Without a Transit Visa?.
Common Mistakes to Avoid
- Assuming visa-free travel applies without checking nationality-specific rules.
- Failing to provide proof of onward travel or required destination visa.
- Misunderstanding airside vs landside transit requirements.
Incorrect applications can delay travel or result in boarding denial. Always confirm requirements before booking your flight.
Frequently Asked Questions
Do I need a visa if I’m connecting through Heathrow?
If you remain in the international transit area and have a valid onward ticket, you may not need a visa. However, certain nationalities always require a DATV, even if remaining airside.
Can I apply for a transit visa on arrival?
No. The UK does not issue transit visas on arrival. You must apply in advance from outside the UK.
How long can I stay in the UK on a transit visa?
You can remain in the UK for up to 24 hours, depending on your flight connection. Longer stays may require a Visitor in Transit Visa.
What if my flight is delayed beyond 24 hours?
If your delay extends beyond the visa’s permitted period, contact UK Border Force immediately for assistance and documentation support.
How much does a UK transit visa cost?
