Travel insurance may be invalidated if you travel contrary to the advice of the Foreign, Commonwealth & Development Office (FCDO).
The FCDO advises against all travel to Iran. British nationals who are already in Iran, whether residents or visitors, should carefully assess the risks of remaining.
British and British‑Iranian dual nationals face a significant risk of arrest, questioning or detention. Possessing a British passport or having perceived links to the UK can be sufficient cause for Iranian authorities to detain you.

Regional tensions
The United States and Iran signed a memorandum of understanding on 17 June concerning the Middle‑East conflict, but the overall situation remains unpredictable. Since 8 July, Iran has carried out strikes and retaliatory attacks on several Middle East should expect possible flight cancellations, periodic airspace closures and other travel disruptions. They should read the GOV.UK guidance “If you’re affected by a crisis abroad”, monitor local and international media, avoid areas around security or military facilities, keep departure plans under review and ensure travel documents are up to date, and, if advised to take shelter, stay indoors or move to the nearest safe building.
If you are in Iran
Air, sea and land routes are controlled by Iranian authorities; ports and borders may close with little notice. Communications across Iran are disrupted, and internet access is limited.
The United States and Israel have struck infrastructure throughout Iran. Reports indicate that ports, roads, railways, bridges, energy facilities, oil production sites, water systems and airports have been affected.
British nationals and British‑Iranian dual nationals face a very high risk of arrest, detention and questioning. Holding a British passport or being perceived as connected to the UK can be enough for Iranian authorities to detain you.
If detained in Iran, you could face months or years of imprisonment.
Travel by air
Iranian airspace may be closed at short notice.
Travel by land
Iran’s borders with neighboring countries may impose restrictions on foreign travel advice of the destination country before heading to the border, including any visa requirements, as entry rules may change quickly.
Entering countries that border Iran is not straightforward, and some may require additional paperwork from British passport holders. Leaving overland is at your own risk. If you need assistance, including help with paperwork, the border remains open visa‑free for travelers holding UK or Iranian passports for stays of up to 90 days. British nationals intending to cross from Iran into Turkey must request facilitation from the British Embassy in Ankara.
