For directors

Terrorism cover for a block of flats. Often excluded by default. Often required by lenders.

Standard buildings insurance excludes terrorism. Pool Re and commercial alternatives add it back. Check your schedule. Check your lenders' criteria. Decide before renewal.

Important
Not legally required, but increasingly standard. Terrorism cover is not a legal duty, but many lenders require it as a mortgage condition. Some leases may require comprehensive cover. Cost is typically £50 to £300 per year for small blocks. Adding cover is straightforward.

Why this matters

Standard buildings insurance excludes terrorism cover by default

This practice dates from the 1993 IRA Bishopsgate bombing, when reinsurers withdrew terrorism cover and the government created Pool Re as a backstop.

Most residential block policies list terrorism as an exclusion. Directors and managing agents often don't realise this until they read the schedule. But if your lenders require it, or your lease says insure for all usual perils, absence is a problem.

Two things have changed. First, post-Grenfell and post-Manchester Arena, terrorism cover is now considered standard for blocks over 18 metres and for blocks in central London. Second, many mortgage lenders (Nationwide, Santander, Lloyds, NatWest, Halifax) now require it as a condition of the mortgage, especially for blocks over £10m sum insured or near landmarks.

This page explains the three common positions, a simple calculator to decide whether you should have it, how to add it, and the cost.

LEASE-iQ insight

LEASE-iQ flags lender requirements from mortgage deeds.

If your block has mixed tenure and multiple lenders, LEASE-iQ reads each mortgagee's requirements and flags if any require buildings insurance with terrorism cover. Use this to brief your broker and check your cover.

Current position

Where your block is likely to sit

Most blocks fall into one of three states. Understanding yours is the first step.

State 1: Cover excluded (default position)

Most blocks today

Your policy schedule lists Terrorism as an exclusion or omits it from named perils.

What this means:
  • Your buildings insurance will not pay for damage caused by a terrorist act
  • You may be in breach of your mortgage conditions (check your mortgage deed)
  • If your lease requires comprehensive cover, you may be in breach of the lease too
  • Leaseholders cannot remortgage or sell if their lender requires terrorism cover

State 2: Cover added via Pool Re

Growing standard

Your policy schedule lists Terrorism as a named peril and references Pool Re.

What this means:
  • Your buildings insurance covers terrorist acts up to your sum insured
  • Pool Re is a government-backed reinsurance scheme (created 1993, still active)
  • Cost is typically £50 to £300 per year, depending on location and sum insured
  • Most major insurers and brokers are Pool Re members; most BIBA brokers can arrange it
  • Central London and high-value blocks pay more; low-risk suburbs pay less

State 3: Cover added via commercial alternative

Niche, sometimes cheaper

Your policy includes terrorism cover from a commercial reinsurer (Hiscox, AIG, Lloyd's syndicates) or a standalone policy.

What this means:
  • Your cover is the same as Pool Re (named peril, full sum insured) but from a different underwriter
  • May be cheaper for low-risk blocks, especially those outside London
  • Underwriting and claims handling may differ from Pool Re; check the detail
  • Some commercial reinsurers have exclusions or limits; verify against Pool Re
  • Less commonly used than Pool Re, so ensure your broker is comfortable with the provider

Who to use

Cost and budget

How terrorism cover is funded

Terrorism cover is a standard insurance add-on, funded like the rest of buildings insurance.

Standard service charge expense

The cost of terrorism cover (typically £50 to £300 per year for a block) is a buildings insurance cost and is recovered through the service charge in the normal way. No special recovery mechanism is needed.

Not a Section 20 item

Important: Buildings insurance is explicitly excluded from Section 20 requirements. Even though terrorism cover is an addition to the insurance premium, it is still insurance and does not trigger Section 20 consultation.

Not a leaseholder vote item

You do not need to consult leaseholders or seek their vote to add terrorism cover. This is a director decision on the same footing as renewing buildings insurance itself.

Annual contract, not QLTA

Terrorism cover is part of your annual buildings insurance contract. It does not create a new contract lasting more than 12 months and does not trigger Qualified Long Term Agreement (QLTA) rules.

Questions

Frequently asked questions

Is terrorism cover legally required?
No, terrorism cover is not a legal requirement for buildings insurance. However, your lease may require comprehensive cover, and many mortgage lenders now require it as a condition. Check both your lease and your lenders' mortgage deeds.
What does Pool Re cost?
Pool Re terrorism cover typically costs £50 to £300 per year for a small block, depending on sum insured, location, and building construction. Blocks in central London or with high sum insured values pay more. Ask your broker for a specific quote for your building.
Does my mortgage require terrorism cover?
Many lenders now require terrorism cover as a mortgage condition, especially for blocks over £10m sum insured, blocks in central London, or blocks near landmarks. Check your leaseholders' mortgage deeds, or ask your broker to do a lender check. LEASE-iQ can flag these requirements from deed text.
What counts as terrorism for insurance purposes?
Insurance definitions typically follow the UK Terrorism Act 2000: acts intended to influence the government or public for the purpose of advancing a political, religious, racial or ideological cause. The definition is broad and covers both violent and non-violent acts that meet this threshold.
Is cyber-terrorism included?
Traditional terrorism cover is for physical damage caused by terrorist acts. Cyber-terrorism (attacks on computer systems or networks) is typically excluded or covered separately under cyber insurance, which is a different product. Ask your broker if you want cyber protection.
Does Pool Re cover all UK blocks?
Pool Re covers most UK properties, including residential blocks. However, some extremely high-risk properties (very high sum insured, sensitive locations) may need commercial cover or may be uninsurable. Your broker will advise if your block falls outside Pool Re's standard terms.
In practice

A typical block's journey to terrorism cover

A managing agent discovers that several leaseholders' mortgages require terrorism cover. The agent checks the current policy, finds it excluded, and adds Pool Re cover at renewal.

Situation: A 12-flat block in a suburb of Manchester, sum insured £800,000, built in 1987. The managing agent is approached by two leaseholders asking whether their mortgages (Nationwide and Santander) might require terrorism cover. One leaseholder is attempting to remortgage and the lender has asked about it.

Action: The agent asks the current broker whether terrorism cover is included. The broker reviews the schedule and confirms it is excluded. The agent requests a Pool Re quote for the next renewal. The quote comes back at £120 per year (about 10% of the total buildings insurance premium). The agent confirms this is acceptable and directs the broker to add it at renewal.

Outcome: At renewal, terrorism cover is added via Pool Re. The agent notifies leaseholders via the annual service charge budget that terrorism cover has been added at £120 per year and explains why (lender requirements, protection for high-value blocks). No Section 20 consultation was necessary. The cost is recovered through the service charge in the normal way.

Next steps

Ready to add terrorism cover?

Follow these steps to get it done.

  1. Check your schedule: Ask your broker whether terrorism is currently excluded or included.
  2. Check your lenders: Ask your broker to check whether any leaseholder mortgages require terrorism cover, or review mortgage deeds yourself.
  3. Get a quote: If excluded or if lenders require it, ask for a Pool Re quote and expected cost.
  4. Decide and notify: Brief your board or management committee and decide whether to add cover.
  5. Action at renewal: Instruct your broker to add terrorism cover via Pool Re (or commercial alternative) at your next renewal date.
