The short answer
No. As of 1 November 2026 the UK has not declared war on anyone, and the government says it is not a party to the wars in the Middle East or Ukraine. Since the Middle East conflict began on 28 February 2026, UK forces have carried out defensive operations, the US can use UK bases for collective self-defence, and the government's stated aim is not to get drawn into the wider conflict. The UK supports Ukraine, and told the OSCE in October 2026 that NATO is not at war with Russia. At home, the government has linked an incident at RAF Fairford in September to Iran. Official advice for households hasn't changed: be ready to manage for 3 days.

The short answer
No. The UK has not declared war, and the government says it is not a party to the conflicts in the Middle East or Ukraine. But British forces are active in both regions in defensive and support roles, which is why the question keeps coming up.
Conflict by conflict
| Where | What the UK is doing | What the government says it is not doing | Source |
|---|---|---|---|
| Iran and the Middle East (since 28 February 2026) | RAF Typhoons and F-35s in coalition defensive operations, intercepting drones; US may use UK bases for agreed defensive purposes, including against missile sites attacking ships in the Strait of Hormuz | Has "not joined US offensive operations"; aims at "not getting drawn into the wider conflict" | PM, 2 March 2026; ministers, 20 March 2026 |
| Saudi Arabia | Air defence and a Voyager refuelling aircraft, against Houthi attacks; 14 missions by 12 October | — | PM statement, 12 October 2026 |
| Strait of Hormuz | Forces committed to a multinational defensive mission, to start "when conditions allow" | — | MOD, 12 May 2026 |
| Ukraine | Military and other support, sanctions on Russia | NATO "is not at war with Russia"; helping a country defend itself does not make you a party to the conflict | UK statement to the OSCE, 14 October 2026 |
The ONS dates the start of the Middle East conflict to 28 February 2026. FCDO travel advice for Iran, updated on 27 October 2026, says the region "remains deeply unpredictable and the risk of sudden escalation is high".
Has anything happened in the UK?
Yes, and the government has been open about it:
- RAF Fairford, 27 September 2026. The Prime Minister told Parliament the incident was "highly likely" coordinated in Iran and "almost certainly" directed by Iran's Revolutionary Guard. In a joint statement on 12 October, foreign ministers of 34 other countries and the EU's High Representative recognised the UK's attribution.
- Iran's ambassador was summoned on 12 October, and two Iranian nationals were sanctioned the same day.
For what the conflict means for fuel, bills, prices and travel at home, see what the Iran war means for UK households. - Russia's "hybrid" activity. The Prime Minister described a Russian campaign of hybrid attacks and sabotage across Europe, and a new UK–Germany partnership to tackle it.
These are security incidents, not a war on UK soil. Police and the security services lead the response.
What the government plans for at home
The National Risk Register 2026 includes a scenario for a conventional attack on the UK mainland using missiles and cyber operations. It says the effects would include disruption to essential services: energy, water, communications, transport, payments. A footnote says a nuclear scenario exists but is held at a higher classification.
That's the reason the government's Be Ready campaign asks every household to be able to manage for 3 days. It isn't a sign that an attack is expected.
What this means for your household
Nothing about daily life has officially changed. The practical steps are the same ones that help in a storm or a long power cut:
- 3 days of water, food and medicines at home (Be Ready: 3 litres of water per person per day).
- A battery or wind-up radio and a charged power bank, so you can hear official updates if the power or phones go down.
- A household plan: who checks on whom, where you'd meet, important numbers on paper. Our free plan maker helps.
- Know how Emergency Alerts work, so a test or real alert doesn't panic you.

What to buy
About these links: plain links to ordinary retailer pages. We may earn from some links in future; we don't now. We haven’t tested these and we don’t rank them: they are examples that were in stock when we checked. Prices change. Check what you already own first. Full kit list
Battery or wind-up FM radio
Look for: FM (Be Ready asks for FM; DAB as well is fine). Both a crank and ordinary batteries, so you have two ways to power it.
Power bank
Look for: From a seller you know. Check the capacity (mAh) against your phone, and that you have the right cable for each phone. Keep it charged.
Torch or head torch, plus spare batteries
Look for: Runs on the same AA or AAA batteries as your other kit, so one spare pack covers everything. A head torch leaves both hands free.

Frequently asked questions
Is the UK at war with Iran?
No, according to the government. The Prime Minister told Parliament on 2 March 2026 that the UK has not joined US offensive operations, and a statement on 20 March says the UK's principles are defending its people, interests and allies, acting under international law, and not getting drawn into the wider conflict. UK forces have carried out defensive operations, and the US may use UK bases for defensive operations.
Is the UK at war with Russia?
No. The UK told the OSCE on 14 October 2026 that NATO is not at war with Russia and seeks no confrontation, and that countries helping Ukraine defend itself are not parties to the conflict.
What wars is the UK currently involved in?
The UK is not fighting a declared war. It is giving military and other support to Ukraine, has carried out defensive operations in the Middle East since 28 February 2026, is supporting Saudi Arabia with air defence and air-to-air refuelling against Houthi attacks, and has committed forces to a planned multinational mission to secure shipping in the Strait of Hormuz when conditions allow.
Will the UK be at war?
We don't predict. The government says it does not seek confrontation and that its aim is to avoid being drawn into the wider Middle East conflict. FCDO travel advice says the Middle East remains deeply unpredictable, with a high risk of sudden escalation. We update this page when official positions change.
Has anything happened in the UK itself?
The government said an incident at RAF Fairford on 27 September 2026 was highly likely coordinated in Iran. Foreign ministers of 34 other countries and the EU's High Representative recognised that attribution on 12 October. The Foreign Secretary summoned Iran's ambassador the same day. Government statements also describe Russian hybrid attacks and sabotage across Europe.
What should I do at home?
The same as before: keep enough water, food, medicines and a radio to manage for 3 days, as Be Ready asks, make a simple household plan, and know how UK Emergency Alerts work. None of this depends on a war starting.
