Can I Claim on Insurance for Business Interruption?

By Jim Flannery ACII, Brand Ambassador, OMC Claims. Over 40 years in insurance claims and a founding member of the Irish Claims Consultants Association.

When something forces your business to stop trading, the damage to the building is often the smaller problem. The lost income, the wages you still have to pay and the customers who drift elsewhere can do far more lasting harm. That is what business interruption cover exists for, and it is also where claims most often go wrong. If you are dealing with a disruption right now, our team can support your business interruption insurance claim from first notification through to settlement.

This guide brings the whole subject together: what the cover does, the events that trigger a valid claim, the policy clauses and extensions that decide how much you recover, how the figures are actually calculated, and the practical steps that protect your position.

What is business interruption insurance?

Business interruption insurance compensates you for lost turnover and gross profit, along with continuing operating costs, when an insured event temporarily stops your business operating. It sits alongside your property cover: the property policy pays to repair the damage, while the interruption cover replaces the income you lose while you cannot trade.

Some policies go further, covering cyber-attacks, supply chain disruption or closure ordered by public authorities, but only where those extensions are written in. A cyber-attack can even cause physical consequences, such as damage to IT systems, fire prevention systems or water pressure systems failing, so the chain between the event and the loss deserves careful attention.

Common causes of business interruption

Interruptions come from many directions, and each affects operations and revenue differently. The ones we see most often in Irish claims are:

• Natural events: storms and flooding that make premises unusable, with flooding a particular and growing Irish problem. Some flood-prone locations struggle to obtain flood cover at all

• Fire and explosions, which can close a premises for months. Where the damage needs planning permission before reinstatement, the disruption period stretches further, and alternative premises rarely restore trading to its previous level straight away

• Supply chain disruption, where a fire or other insured event at a key supplier or key customer’s premises halts your own production and/or sales

• Cyber attacks that lock you out of critical systems, covered only where your policy includes a cyber extension

• Government-mandated closures, of the kind seen during the pandemic, which most standard policies exclude

Recognising the likely causes for your own business is the first step in checking that your cover, and your continuity planning, actually match your risks.

Does insurance cover business interruption?

Yes, business interruption cover is commonly included within a commercial property or commercial combined policy, or available as an add-on, but the scope varies widely. It typically responds to income loss following insured property damage such as fire, storm or flood.

Just as important is what it does not cover. Standard exclusions include war, nuclear events, and wear and tear. Pandemics and cyber events are usually excluded unless specifically added. And a slowdown caused by market conditions, reduced footfall or an economic downturn is not an insured event at all: the policy responds to specific, sudden occurrences, not commercial headwinds.

The material damage proviso and types of cover

Most business interruption sections contain a material damage proviso: there must be physical loss or damage to the building, contents or stock before the business interruption claim is valid, and that physical loss must itself be insured. You cannot claim interruption losses following a fire if fire cover is missing from the policy, and the same applies to flood, which is excluded from many policies in higher-risk areas.

Within that framework, the main types of cover are:

• Following physical damage to property: the core cover, compensating loss of gross profit, less any savings, plus increased cost of working during the indemnity period

• Loss of utilities: interruption caused by failure of electricity, water or gas supply, where the extension is included

• Contingent business interruption: losses caused by insured damage at a key supplier’s or customer’s premises, for example a supplier’s factory destroyed by fire when the same products cannot be sourced elsewhere

• Denial of access: compensation where authorities restrict access to your premises following an insured event nearby, even though your own property is undamaged

What events trigger a business interruption claim?

Insurers require the cause to be insured, sudden and unforeseen physical damage. Across Irish claims, the most common triggers are:

• Fire and smoke damage, including small fires that make premises unsafe or production impossible. Working alarms, regular electrical inspections and staff fire training all reduce the risk

• Flooding and storm damage, especially for premises near rivers, coastlines or poor drainage. Flood barriers, stock stored off the ground and confirmed flood cover matter here

• Burst pipes and water leaks, which can destroy stock and close a premises overnight, particularly during cold snaps. Insulate exposed pipes and watch water bills for hidden leaks

• Break-ins, theft and vandalism, where stolen equipment or damage prevents reopening until repairs are made. Alarms, CCTV and security logs support both prevention and any claim. The period of disruption may be short-lived but no less important to obtain indemnity for the loss of profit, as the expenses of the business are likely continuing.

• Machinery breakdown, where key equipment fails suddenly and accidentally rather than through wear and tear. Strict maintenance schedules and service records are essential evidence

• Supplier or utility disruption, valid where your policy carries the relevant extension. Identify your supply chain risks and discuss dependent property cover with your broker

The dividing line matters. A halted production line caused by an insured fire is a trigger. A quiet quarter caused by changing customer habits is not.

The key policy clauses and extensions

A handful of clauses do most of the work in any business interruption policy. Reading them before you need them is worth an hour of anyone’s time.

Indemnity period

The maximum length of time your insurer will compensate you after a disruption, typically 12 to 36 months. The claim runs for as long as it takes to restore turnover to where it should have been, capped at this period.

Material damage proviso

As above: physical loss or damage, itself insured, must occur before the interruption claim is valid. If flooding blocks access to your building without damaging it, this proviso bites unless you hold a denial of access extension.

Denial of access

Covers lost turnover where authorities restrict access to your premises. A fire in a neighbouring building that closes the road can qualify, even with no damage to your own property.

Contingent business interruption

Extends cover to interruptions at the premises of your suppliers or customers. If your main raw materials supplier floods and cannot deliver, halting your production, this extension can respond.

Utilities interruption

Covers losses where public utilities fail, for example a storm taking out the power grid and shutting a manufacturing plant for days.

Cyber interruption

A newer extension covering lost turnover and increased cost of working after a cyber-attack or data breach. Ransomware that halts operations is the obvious case, and a breach that disables safety or manufacturing systems can add physical losses on top.

Is your indemnity period long enough?

Many business interruption policies default to 12 months without asking how long recovery would genuinely take. In our experience that is often too short, for reasons that have become more pronounced in recent years:

• Planning permission for demolition or significant rebuilding commonly takes three to six months or more in Ireland

• Construction lead times remain long, with contractor and material shortages extending repair schedules

• Inflation in build costs can cause overruns and delays where budgets were set at yesterday’s prices

• Specialist or imported machinery can take many months to replace, and a single unavailable part can stall production

• Supply chain constraints affect replacement stock and equipment across most sectors who operate to a just-in-time model

Discuss the period with your broker and set it against a realistic recovery timeline for your specific operation: the complexity of the business, the difficulty of sourcing equipment, third-party approvals such as fire certificates and engineers’ reports, and access to skilled contractors. An inadequate period leaves the business unprotected at exactly the stage it is scaling back up to full trading.

How business interruption claims are calculated

A business interruption policy aims to put the business back in the financial position it would have occupied had the event not happened. It typically covers loss of gross profit, fixed operating costs that continue while you are closed (rent, salaries, loan repayments, utilities), and increased cost of working, meaning additional spending to keep trading or recover faster, such as temporary premises or outsourced production.

One warning deserves emphasis: gross profit in insurance is not the same as gross profit in accounting. The insured figure broadly means turnover less uninsured variable costs, and if your sum insured is based on the accounting definition, you can end up underinsured without knowing it.

Insurers policy wordings also allow to apply trends and adjustments. Year-on-year growth, seasonal patterns and expansion plans all feed into the projection of what the business would have earned, which is why the claim rests on what you reasonably would have made, not simply last year’s turnover.

A simplified example: a business turning over 60,000 euro a month with a gross profit rate of 40 per cent is closed for three months. The starting loss is 180,000 euro of turnover, or 72,000 euro of lost gross profit. Add 8,000 euro of increased costs for temporary premises, deduct 5,000 euro of savings on utilities and consumables, and the claim sits in the region of 75,000 euro before trends adjustments. Real claims are rarely this tidy, which is why the financial preparation matters as much as the damage report.

When claims are refused

Even with good cover, claims fail for recurring and mostly avoidable reasons:

• Insufficient documentation: your claim will need your latest financial statements, monthly management accounts, sometimes daily sales records and you may be asked for invoices for stock or equipment purchases to validate figures or establish lead times. Missing paperwork prejudices the claim

• Policy exclusions: an interruption caused by an uninsured peril will not be paid, however real the financial impact

• Delayed notification: some policies require notice within 30 days or less, and late reporting is a technical breach the insurer can rely on

• Underinsurance: the sum insured is usually based on annual gross profit or gross revenue, but it must be projected forward through the policy year and the year after, because an incident on the last day of the policy still needs cover for the whole disruption period. An inadequately calculated figure triggers a proportionate deduction for underinsurance, even though the full gross profit is never paid out, as savings on overheads are always deducted while the business is closed

Immediate steps and the documents you will need

When a disruption hits, the first moves are practical. Assess the situation and make people and premises safe. Notify your insurer or broker promptly, with preliminary details. Document the damage with timestamped photographs, video and written notes, including operational impacts such as cancelled bookings. Take reasonable steps to limit further loss, whether that means securing the property, relocating critical operations or temporarily outsourcing part of the business. And keep stakeholders informed: staff, customers, suppliers, and where necessary your bank or investors, who would rather hear about a need for temporary forbearance in real time than after the business is in difficulty.

For the claim itself, assemble:

• Financial statements plus monthly or weekly sales figures for the previous 12 or 24 months, which also evidence seasonal peaks and growth trends

• Proof of the interruption: photographs, incident reports, emergency service references

• Your policy schedule and full wording

• Receipts for every additional expense, from temporary premises to extra staffing hours

• A running log of correspondence with the insurer, dated

The claims process, step by step

Business interruption claims are financial arguments presented through a formal process, and each stage benefits from preparation.

Initial notification comes first, promptly and in writing. The insurer will then appoint a loss adjuster. It is worth being clear about roles here: the loss adjuster assesses the loss and reports to the insurer. They are not there to present your claim. That is the loss assessor‘s job, acting only for you: preparing the figures, providing documentation, and negotiating with the adjuster.

Policies are complex legal documents, and the calculation looks forward as well as back. Most accountants deal in historical figures rather than projected trading, which is why interruption claims sit awkwardly with normal book-keeping and why specialist preparation makes a measurable difference.

Once the claim is accepted, the settlement is negotiated and agreed, then paid. Before signing anything, check the figures against your own calculation of lost gross profit, savings, increased costs and trends. If the claim is refused or the offer looks light, the position can be reviewed and appealed; a refusal is not necessarily the end of the matter.

Preventing business interruption in the future

Insurance is the safety net, not the plan. Regular risk assessments identify the exposures worth engineering out, from fire systems to cyber defences. Contingency plans, including alternative suppliers and temporary operating arrangements, shorten any disruption that does occur. And an annual review of the policy itself, particularly the sum insured, the indemnity period and the extensions, keeps the cover in step with the business as it grows and changes.

Frequently asked questions

What is business interruption insurance?
It compensates for lost income and continuing expenses when a business cannot operate because of a covered event. It sits alongside property cover, which pays for the physical damage itself.

What events trigger a business interruption claim in Ireland?
Common triggers include fire and smoke damage, flooding and storms, burst pipes, theft and vandalism, sudden machinery breakdown, and, where policies carry the extensions, supplier disruption, utility failure or denial of access.

How is a business interruption claim calculated?
By applying the insured rate of gross profit to the reduction in turnover during the indemnity period, adding increased costs of working, deducting savings made while closed, and adjusting for business trends and seasonality.

How long does business interruption cover last?
For the indemnity period stated in the policy, usually 12 months as standard and extendable to 18, 24 or 36 months. The claim runs for as long as it takes to restore turnover to where it should have been, within that limit.

Can I claim if my premises were not damaged but I had to close?
Only where the policy includes the relevant extension, such as denial of access or utility failure. The standard material damage proviso otherwise requires insured physical damage before an interruption claim is valid.

Are natural disasters covered under business interruption insurance in Ireland?
Storms and flooding are typically covered where they are insured perils on the policy. Flood cover varies considerably and can be restricted in higher-risk locations, so check the wording.

Do I need a separate policy for cyber-related interruptions?
Often, yes. Cyber events are usually excluded from standard cover, so a cyber interruption extension or a dedicated cyber policy is needed for protection against attacks that halt trading.

Can small businesses afford business interruption insurance?
Yes. Tailored policies exist for small businesses, including home-based ones, at manageable cost, and the protection generally far outweighs the premium. Make sure the insurer knows the nature of the operation.

What happens if my claim is denied?
You can appeal the decision, and it is worth having the refusal reviewed. A regulated loss assessor can identify gaps in the presentation, provide additional evidence and take up the argument with the insurer.

If your business has been disrupted, the two steps that most affect the outcome are notifying your insurer promptly and getting the financial evidence in order early. OMC Claims acts only for policyholders, across all 26 counties. Contact us for a free, no-obligation conversation about your claim.
