Terrorism and political violence insurance UK

The exclusion most policyholders never read

Almost every standard commercial property policy in the UK excludes loss or damage caused by terrorism. The exclusion sits quietly in the wording, and because premises damage from terrorism is rare, many businesses only discover it when a lender, landlord or auditor asks whether terrorism cover is in place. The honest starting position for any UK property owner or tenant is: unless you have bought it back, you do not have it.

That buy-back happens in one of two ways: through the Pool Re scheme via your existing property insurer, or through the standalone terrorism and political violence market. They are different products with different wordings, and the differences matter.

How Pool Re actually works

Pool Re is the UK's government-backed terrorism reinsurance scheme, set up after the mainland bombings of the early 1990s made terrorism commercially uninsurable. You do not buy a policy from Pool Re directly. Your property insurer, if it is a member of the scheme, extends your policy to include terrorism and then reinsures that exposure into the pool, which is in turn backstopped by HM Treasury.

Practically, that means terrorism cover bought this way attaches to your existing property policy: same sums insured, same sites, following the material damage and business interruption cover you already hold. It is generally written across your whole property account rather than cherry-picked for a single high-profile site, which is part of how the scheme keeps the pool balanced.

What counts as an act of terrorism

Cover under the scheme responds to acts certified as terrorism under the relevant legislation, with certification made by HM Treasury. That certification mechanism gives the market a clear trigger: either an event is certified and the scheme responds, or it is not and you are back to your underlying policy and its exclusion.

The certified-act structure removes argument about motive after the event, but it also defines the edge of cover. Events that look like terrorism to a layperson but are not certified, and perils such as riot or malicious damage, fall to other parts of your programme, which is exactly why the surrounding wordings need to be read together.

Non-damage denial of access

The classic gap used to be the police cordon. An incident streets away damages nothing you own, but the cordon closes your premises for days and the till stops. Traditional terrorism cover followed physical damage, so a business interrupted without damage recovered nothing.

The market has moved. Pool Re is now able to cover business interruption without physical damage to the insured's own property following a terrorist event, and standalone wordings offer non-damage denial of access extensions of varying quality. The width of the extension, the radius it applies to, the indemnity period and how the trigger is defined vary between wordings, and this is where a broker earns the fee: two policies both labelled terrorism can respond completely differently to the same cordon.

Political violence: broader perils beyond Pool Re

Standalone political violence wordings go wider than certified terrorism. Depending on the form, they can pick up strikes, riots and civil commotion, malicious damage with a political motive, sabotage, and on international programmes perils up to insurrection and war-adjacent risks that no domestic property policy touches.

For a UK-only risk, the choice is usually between the scheme's certified-act certainty and a standalone wording's flexibility on sites, limits and perils. For businesses with overseas premises or supply chains, political violence cover is often the only way to insure perils that local policies exclude. The right answer depends on the footprint, not on a standard recommendation.

Who genuinely needs it, and how it is bought

Three groups should take the question seriously. City-centre and landmark-adjacent premises, and anything near transport hubs or crowded places, carry obvious exposure including the cordon scenario. Borrowers, because mortgage conditions on commercial property frequently require terrorism cover, and an uninsured certified act would leave the lender's security impaired. And landlords and tenants, because leases often oblige one party to insure terrorism, sometimes with the cost recharged through the service charge.

Buying it is straightforward once the need is defined: an extension through your property insurer into Pool Re, or a standalone policy where the scheme's structure does not fit, for instance where you want a single site covered, a specific limit rather than full value, or perils beyond certified terrorism. We place both routes and will tell you plainly which fits your risk.

What to have ready before asking for terms

Terrorism underwriting is largely about location and values, so the submission is simple to assemble: full addresses and postcodes for every site, buildings and contents sums insured consistent with your property policy, your business interruption basis and indemnity period, and a note of any lease or lender clause that dictates what the cover must say. If a lender is involved, get the exact wording of its requirement, because satisfying the clause, not just buying something labelled terrorism, is the point of the exercise.

Review the cover whenever the portfolio changes. A new site, a moved head office or a revised rebuild cost changes the terrorism picture just as it changes the property one, and because scheme cover follows your property policy, the two need to move together at every renewal.

Frequently asked questions

Is terrorism covered by my standard commercial property policy?

Almost certainly not. UK commercial property wordings exclude terrorism as standard. Cover has to be bought back, either through the Pool Re scheme via your property insurer or from the standalone terrorism market.

Do I have to insure through Pool Re?

No. Pool Re is the government-backed scheme accessed through participating property insurers, and it suits many risks, but there is a standalone terrorism and political violence market offering different structures, single-site cover and broader perils. Which route fits depends on your premises and obligations.

Does terrorism cover include business interruption?

Yes, where it is set up to. Cover bought through your property insurer can follow your business interruption cover, and the market now offers non-damage denial of access protection for cordon scenarios where your own property is undamaged. The width of that extension varies significantly between wordings.

Who decides whether an event was terrorism?

For scheme cover, acts are certified under the relevant legislation with certification by HM Treasury. That certification is the trigger: a certified act engages the cover, an uncertified event falls back to your underlying policies.
