UK Transit Visa: Do You Need One? Complete Guide for 2026
Travelling through London? Find out if you need a UK transit visa based on your nationality, destination, and documents like Canadian PR, US Green Card, or other visas.
Do You Need a UK Transit Visa?
If you're flying through the UK to reach another destination, you might need a transit visa — even if you're not leaving the airport. This catches many travellers off guard, leading to denied boarding or being turned away at the airport.
This guide explains who needs a UK transit visa, who is exempt, and how to check your specific situation.
Types of UK Transit
1. Airside Transit (Staying in the Airport)
You don't pass through UK border control. You stay in the international transit area and catch your connecting flight.
- You don't enter the UK officially
- You can't leave the airport
- Flight must depart before midnight the day after arrival
2. Landside Transit (Entering the UK)
You pass through UK border control. This happens if you need to:
- Collect checked baggage and re-check it
- Change terminals (some airports require this)
- Stay overnight at a hotel outside the airport
- Have a very long layover
Direct Airside Transit Visa (DATV)
Some nationalities need a Direct Airside Transit Visa (DATV) even if they're just connecting through the airport without entering the UK.
Countries That Require a DATV
Nationals of these countries typically need a DATV for airside transit:
- 🇮🇳 India
- 🇨🇳 China

- 🇱🇰 Sri Lanka
- 🇳🇬 Nigeria
- 🇬🇭 Ghana

Frequently Asked Questions
Do I need a transit visa if I have a UK visa?
No. If you have a valid UK visa (tourist, work, study, etc.), you don't need a separate transit visa.
My flight is on one ticket — do I need to collect bags?
Usually no. If booked on one ticket with the same airline or partner airlines, bags are typically checked through to your final destination. Confirm with your airline.
What if my Canadian PR Card is expired?
An expired PR card does NOT provide exemption. You would need to either renew it or apply for a DATV.
Does a US visa stamp count if it's in my old passport?
Yes, as long as the visa is still valid and you carry both passports (old passport with visa + new valid passport).
Can I leave the airport during transit?
Only if you have the right to enter the UK (valid UK visa or don't need one for your nationality). Otherwise, you must stay airside.
How long can I transit without a visa?
Your connecting flight must depart before midnight the day after you arrive. For example, if you arrive Monday at 10am, you must depart by Tuesday 11:59pm.
