Force Majeure Events: Meaning, Clauses And Contract Impacts

When you’re running a small business, you’re used to dealing with surprises - supplier delays, staffing issues, and the occasional “how did that happen?” moment.

But some disruptions are bigger than day-to-day bumps. Think major storms, sudden changes in law, or a supply chain collapse that makes it impossible (not just inconvenient) to deliver what you promised.

This is exactly where force majeure comes in. If your contract has a well-drafted force majeure clause, it can give you breathing room and a clear process when the unexpected hits. If it doesn’t, you could be stuck with liability for something completely outside your control.

Below, we’ll break down the force majeure definition, what a force majeure clause usually does, and how to make sure it actually protects your business in real-world scenarios.

What Is A Force Majeure Event (And Why Does It Matter In Business Contracts)?

Let’s start with the basics. A force majeure event is generally an extraordinary event (or series of events) that is outside a party’s reasonable control and prevents them from performing their contractual obligations.

In plain English: it’s the “we couldn’t do it because something major happened that we couldn’t prevent” concept - but it only works the way you want if your contract is drafted properly.

Force Majeure Definition: Is It A Legal Term With A Fixed Meaning?

In UK contract law, force majeure doesn’t have one automatic, fixed definition that applies to every contract. Unlike some legal concepts that are implied by statute, force majeure is usually a contractual protection.

That means you generally only get the benefit of a force majeure clause if your contract includes one - and the detail of that clause is what matters. If you don’t have a clause, you may still have arguments under other legal doctrines (like frustration), but those are narrow and fact-specific, and they don’t operate in the same way as a tailored force majeure clause.

This is why it’s worth getting your contract terms right from the start, especially if your business relies on delivery timelines, events, projects, or ongoing supply arrangements. (If you’re reviewing your overall approach to contracts, having a clear handle on contract law basics is a good foundation.)

Force Majeure Event vs “Harder Or More Expensive To Perform”

One of the most common misunderstandings is assuming force majeure covers any situation where performance becomes difficult or costly.

Usually, it doesn’t.

Many force majeure clauses are triggered only when performance becomes impossible (or close to it), not merely unprofitable. For example:

• Not enough staff due to poor workforce planning is unlikely to be force majeure.
• A predictable seasonal delay in shipping is usually not force majeure.
• A sudden legal ban on providing the service you contracted to provide may be force majeure (depending on drafting).

In other words: a force majeure clause is not a “get out of contract free” card. It’s a risk management tool for genuine, external shocks.

What Is A Force Majeure Clause And How Does It Work?

So, what is a force majeure clause in practice?

A force majeure clause is a contract term that sets out what happens if a force majeure event occurs. It typically covers:

• Which events count (the definition and examples list)
• What obligations are affected (e.g. delivery deadlines, service levels, payment)
• What relief is available (e.g. time extension, suspension, termination)
• Notice requirements (how quickly you must notify the other party, and what details must be included)
• Steps to reduce impact (often called mitigation obligations)

Because this clause can shift legal risk in a big way, it needs to be tailored to your specific deal and industry. Generic templates often miss the key points that actually matter when a dispute happens.

If you’re negotiating a contract and need the clause to do something specific for your operations (like protecting your supply chain), it’s worth getting proper clause drafting support rather than relying on “standard wording”.

What Does A Typical Force Majeure Clause Do?

Most force majeure clauses do one or more of the following when a force majeure event occurs:

• Suspends performance for the duration of the event
• Extends deadlines (for example, delivery dates move out)
• Limits liability (so the affected party isn’t in breach for non-performance caused by the event)
• Allows termination if the event continues beyond a set period (e.g. 30, 60, or 90 days)

Whether you want suspension, termination, or a tighter process depends on what you do. A business running weddings or ticketed events may need a different approach than a business supplying components to manufacturers.

What Counts As A Force Majeure Event? Common Examples (And Grey Areas)

Most contracts don’t rely on a vague definition alone. They include a list of force majeure events - and that list is often where the real negotiation happens.

Common examples of a force majeure event include:

• Natural disasters (floods, earthquakes, severe storms)
• Fire (particularly where it affects facilities, stock, or essential infrastructure)
• War, terrorism, civil unrest
• Government action (embargoes, bans, compulsory closures)
• Changes in law that make performance unlawful
• Public health emergencies (where specifically included)
• Industrial action (strikes and labour disputes - often heavily negotiated)
• Utility or infrastructure failures (power outages, telecom failures)

Grey Area: Supply Chain Disruption

Supply chain disruption is one of the most argued-over topics in modern contracts.

Whether a supplier shortage counts as a force majeure event depends on:

• what the clause says (does it mention supplier failure or shortages?)
• whether the disruption was foreseeable and plan-able for
• whether you could reasonably source elsewhere (even if it costs more)

If your contract is silent and simply says “events beyond reasonable control,” you can still run into disputes about whether you should have mitigated the issue by using alternatives.

Grey Area: Cyber Incidents

For many businesses, a serious cyber incident can stop operations overnight.

But whether it’s a force majeure event depends on how your clause is drafted. If cyber events matter to your business (ecommerce, SaaS, marketing platforms, data-heavy services), consider explicitly including:

• major systems outages
• third-party hosting failures
• cyberattacks (e.g. ransomware)

And if you process personal data, remember that relying on force majeure doesn’t remove your data protection responsibilities. You’ll still want strong privacy compliance in place, including a fit-for-purpose Privacy Policy and internal processes for incident response.

What Happens When A Force Majeure Event Occurs? Practical Steps For Small Businesses

When something major happens, it’s tempting to go straight into problem-solving mode (which is fair). But with force majeure, the contract process matters - and missing a notice deadline can cost you your protection.

Here’s a practical sequence most businesses should follow.

1) Check The Contract Wording First

Before you tell the other side “this is force majeure,” check:

• Does the contract have a force majeure clause?
• Does the event fit the definition/list?
• What obligations are affected? (Some clauses exclude payment obligations.)
• What does the clause require you to do next?

If you’re not sure how the clause interacts with the rest of the contract (for example, termination, service levels, or liability caps), it may help to have the agreement reviewed as a whole rather than reading the clause in isolation.

2) Give Notice Properly (And On Time)

Many force majeure clauses require notice:

• within a specific timeframe (sometimes very short)
• in a specific format (e.g. writing, email to a nominated address)
• with specific information (what happened, when it started, what obligations are impacted)

If you don’t comply with the notice procedure, you may lose your right to rely on the clause - even if the event clearly is a force majeure event.

3) Document The Impact And Your Mitigation Steps

Force majeure clauses often require you to take reasonable steps to reduce the impact of the event. Even when it doesn’t say that explicitly, being able to show you acted reasonably can make disputes much easier to resolve.

Practical evidence might include:

• supplier emails confirming shortages or closures
• government announcements or regulatory notices
• attempts to source alternatives
• internal notes showing operational impacts

4) Consider Whether You Need To Vary The Contract

Sometimes the best outcome is not to argue about whether the event technically qualifies, but to agree a commercial workaround.

That might mean adjusting timelines, pricing, scope, or delivery methods. To do that safely, you’ll generally want a written change document, such as a variation agreement or (depending on the structure of the original contract) a Deed of Variation.

If your contract has a strict variation process, make sure you follow it - otherwise you can end up with uncertainty about what was agreed.

5) Think About The Endgame: Suspension vs Termination

Many force majeure clauses allow termination if the event continues beyond a set “long stop” period.

That can be helpful, but it’s also risky if you terminate too early or without meeting the clause requirements. If you’re heading toward termination, consider:

• what ongoing obligations survive termination (confidentiality, payment for work done, IP licences)
• how deposits or prepayments are dealt with
• whether a negotiated exit is safer than relying on a clause

If you’re trying to end the contract cleanly, you may need a formal termination letter that aligns with your contractual notice requirements.

How To Draft (Or Negotiate) Force Majeure Clauses That Actually Protect Your Business

Force majeure clauses are one of those contract terms that look “standard” until you actually need them. Then every word matters.

If you’re drafting or negotiating a force majeure clause for a business contract, here are the key points to focus on.

Be Specific About The Events That Matter To Your Industry

A restaurant group might worry about utility outages and supplier failure. A software business might worry about hosting outages and cyber incidents. An events business might worry about venue closures and restrictions on gatherings.

Your force majeure event list should reflect your real operational risk - not just a copied list from another industry.

Define The Level Of Impact Required

Does the force majeure event need to:

• prevent performance entirely?
• make performance impracticable?
• cause material delay?

Different thresholds create different levels of protection (and different levels of risk to the other party). This is often where negotiations land.

Build In Clear Notice And Communication Rules

Notice rules are not just admin. They reduce disputes because both parties know:

• when force majeure is being claimed
• which obligations are affected
• when updates will be provided

If you’re the party likely to be affected (for example, you rely on third-party deliveries), you may want the clause to require frequent updates and a duty to resume performance as soon as reasonably possible.

Decide What Happens To Payments

One of the biggest commercial issues is whether payment obligations are suspended. Some clauses say payment is still due even if services are suspended. Others allow payment to be paused or adjusted.

There isn’t a one-size-fits-all answer - it depends on bargaining power and what’s fair for the deal - but it’s better to address it directly than to leave it unclear.

Check How Force Majeure Interacts With Change Processes

Most contracts include a “variation” clause explaining how changes must be agreed. If you do agree a workaround during a force majeure event, it should follow that process.

If you need help making changes properly, an amendment agreement can document the new arrangement clearly and reduce the risk of arguments later.

Don’t Forget The Basics: A Clause Only Works Inside A Valid Contract

It sounds obvious, but it’s a real issue for small businesses moving quickly. If the contract itself is unclear or hasn’t been properly formed, your force majeure clause may not help you in the way you expect.

If you’re ever unsure whether you’ve got a binding agreement in the first place (for example, you agreed key terms over email and started work), it’s worth understanding when a contract is legally binding.

Key Takeaways

• A force majeure event is typically an extraordinary event outside your control that prevents you from performing a contract - but in the UK it usually depends on what your contract says (most commonly through a force majeure clause).
• The wording of a force majeure clause matters hugely: it defines what events count, what relief you get (suspension, time extensions, termination), and what notice you must give.
• Many “grey area” disruptions (like supply chain issues or cyber incidents) may not be covered unless the clause is drafted with your business risks in mind.
• If a force majeure event occurs, follow the contract process: check the clause, give notice correctly, document the impact, and mitigate where possible.
• Often the most practical solution is a written contract variation (rather than an argument about definitions), but it needs to be documented properly.
• If your contracts are customer- or supplier-critical, getting the force majeure clause tailored to your operations can save your business serious time, cost, and stress later.
