What Is A Force Majeure Clause In Business Contracts? (2026 Updated)

When you're running a business, you can do everything "right" and still get hit with something completely outside your control.

A key supplier suddenly can't deliver. A port strike stalls your shipments. A cyber incident knocks out critical systems. A new government restriction makes an event impossible to run. Your team is ready to go - but the world has other plans.

This is exactly where a force majeure clause can help. It's one of those contract terms you don't think about until you really need it, and by then it's too late to add.

In this 2026-updated guide, we'll walk you through what a force majeure clause is, how it works in UK business contracts, what to include, and the common drafting mistakes that can leave you exposed.

What Is A Force Majeure Clause (And Why Does It Matter)?

A force majeure clause is a contract term that sets out what happens if an unexpected event outside a party's reasonable control stops them from performing their contractual obligations.

In plain English, it's the "something happened that we couldn't reasonably prevent, so we need a temporary workaround" clause.

It matters because, under English and Welsh contract law, there isn't a universal automatic right to pause performance just because circumstances become difficult. The legal outcome depends heavily on what the contract says and how it's drafted.

That's why getting your contract basics right early on is so important - it's not just about having a document signed, it's about making sure the document actually works when things go wrong.

Force Majeure vs "Hardship" (They're Not The Same)

A common misconception is that force majeure covers any scenario where performance becomes harder, slower, or more expensive.

Usually, it doesn't.

Most force majeure clauses are designed for impossibility (or near-impossibility), not inconvenience. If your supplier costs double and your margins disappear, that may be painful - but it's not always force majeure unless the clause is drafted broadly enough to catch it.

Force Majeure vs "Frustration" Under UK Law

You may also hear about the common law doctrine of frustration. This is separate from force majeure.

• Force majeure is contractual (it exists because you wrote it into your agreement).
• Frustration is a legal doctrine (it can apply even if your contract doesn't mention it, but it's narrow and fact-specific).

Frustration is typically harder to rely on and can lead to the contract ending automatically, rather than pausing it. For most businesses, it's far safer to define your own "what happens if the unexpected occurs" process through a properly drafted force majeure clause.

When Should You Include A Force Majeure Clause?

If you're thinking "do I really need this?", the practical answer is: most businesses should consider it in any contract where timing, delivery, availability, or third-party dependencies matter.

Force majeure clauses are particularly common (and valuable) in:

• Supply agreements (raw materials, manufacturing, logistics, distribution)
• Service agreements (especially where services depend on access, venues, platforms, or key personnel)
• Construction and installation contracts (weather events, shortages, site access restrictions)
• Events and venue hire arrangements (government restrictions, transport disruption, safety incidents)
• Tech and SaaS arrangements (major outages, cyber incidents, third-party infrastructure failures)
• International contracts (cross-border disruptions, sanctions, export restrictions)

Even if you're working with long-term partners, it's still worth having the clause. It can protect the relationship by giving both parties a clear "playbook" for what to do, rather than falling into a dispute when emotions are high.

Common 2026 Scenarios Businesses Are Planning For

Force majeure drafting has evolved a lot since the early 2020s. In 2026, many UK businesses are specifically looking to address:

• Supply chain disruption (shipping delays, container shortages, port closures)
• Energy disruption (grid failure, rationing, critical infrastructure issues)
• Cyber incidents (ransomware, major outages impacting ability to deliver)
• Regulatory or sanctions changes (especially for cross-border suppliers and payments)
• Industrial action (strikes affecting transport, ports, postal services)
• Public health emergencies (restrictions impacting staffing or onsite operations)

Not every event above will automatically count as force majeure - it depends on your wording. The key is to decide which risks you want to allocate and how.

What Should A Good Force Majeure Clause Include?

A force majeure clause isn't just a list of dramatic disasters. A good clause is really a process: it defines what qualifies, what each party must do, what happens to obligations, and when either party can walk away.

Here are the building blocks we typically look for.

1) A Clear Definition Of "Force Majeure Event"

This is where many contracts go wrong: the definition is either too narrow (so you can't use it) or too vague (so it becomes a dispute magnet).

Many clauses define a force majeure event as something like:

• an event outside the affected party's reasonable control,
• which could not have been avoided by reasonable steps, and
• which prevents or materially delays performance.

Then they usually add a non-exhaustive list of examples, such as fire, flood, earthquake, war, terrorism, government action, pandemic restrictions, failure of utilities, strikes, and so on.

2) Causation: The Event Must Actually Prevent Performance

It's not enough that the world is messy. You generally need to show a direct connection between the event and your inability to perform.

For example:

• If a port strike prevents your goods leaving the country, that's a direct barrier.
• If your costs go up due to general inflation, that might not be enough (depending on wording).
• If you could still perform by using an alternative supplier at a higher cost, your clause might require you to do that (again, depending on wording and what "reasonable" looks like in context).

This concept is closely linked to how contracts interpret "reasonable" steps - the same kind of logic also shows up in clauses about reasonable efforts.

3) Notice Requirements (When And How You Must Tell The Other Party)

Most force majeure clauses require the affected party to notify the other party:

• as soon as reasonably practicable (or within a set number of days),
• explaining the event, the obligations impacted, and the expected duration, and
• providing updates as the situation changes.

This might sound administrative, but it's often the difference between protection and breach. If your contract says "notify within 5 days" and you notify in 20, you may lose the benefit of the clause.

It's also worth checking your "notices" section generally, including whether email is valid and which addresses are authorised - issues like this come up in disputes more often than you'd think, especially when people assume email is always fine because emails are legally binding in other contexts.

4) Duty To Mitigate (What You Must Do To Reduce The Impact)

Many clauses require the affected party to take reasonable steps to mitigate (reduce) the effects of the force majeure event.

In practice, this could mean:

• sourcing alternative materials, routes, or subcontractors (if realistic),
• implementing contingency plans (backup systems, alternative delivery methods),
• prioritising partial deliveries or phased performance,
• shifting timelines to keep the project alive rather than abandoning it.

A well-drafted mitigation obligation should feel fair to both sides: it shouldn't require heroics or financial self-destruction, but it also shouldn't allow a party to do nothing.

5) The Contract Consequences: Suspension, Extensions, Or Termination

This is the heart of the clause: what happens to each party's obligations?

Common outcomes include:

• Suspension of the affected obligations while the event continues
• Extension of time to perform, without penalties
• Relief from liability for delay/non-performance caused by the event
• Termination right if the event continues beyond a set period (e.g. 30, 60, or 90 days)

For businesses, the termination trigger is crucial. You don't want to be stuck in indefinite limbo - but you also don't want the other party to terminate too quickly when a short delay would have been manageable.

This is also a good time to check how your contract handles endings generally, because force majeure is often drafted alongside broader contract expiry options and termination rights.

6) Payment Provisions: Do You Still Have To Pay?

This is where you want to slow down and be specific.

A force majeure clause might deal with payment in different ways depending on the type of contract:

• Goods contracts: if goods aren't delivered, payment might be paused; if goods are partially delivered, partial payment might be required.
• Service contracts: payment might be linked to milestones, time spent, or deliverables - and the clause should align with that structure.
• Subscriptions/retainers: you may want to specify whether fees continue if the service is unavailable due to force majeure, and whether credits apply.

Without clarity, you can end up with a commercial standoff: one party says "we can't deliver", the other says "then we won't pay", and suddenly you're in dispute about whether the contract permits either position.

How Does Force Majeure Interact With Other Key Contract Clauses?

Force majeure doesn't live in isolation. In real disputes, it's interpreted alongside other terms in the agreement - and sometimes those other terms quietly undo the protection you thought you had.

Limitation Of Liability Clauses

Many contracts include caps or exclusions for certain losses (like loss of profit). A force majeure clause can reduce the risk of a party being liable at all during the relevant period, while a limitation of liability clause controls the size and type of any claims if liability still arises.

These clauses should be drafted to work together, not contradict each other. It's common to address this in a tailored limitation of liability approach that matches the real commercial risks in your deal.

"Notwithstanding" Clauses And Priority Terms

Some contracts include language like: "Notwithstanding any other clause?" which can give one part of the contract priority over another.

If you're not careful, you might have a force majeure clause that says obligations are suspended, but another clause that says payment obligations continue "notwithstanding" anything else. That can create a nasty surprise.

If you've ever skim-read that wording, you're not alone - but it can matter a lot, and it's why it's worth understanding how notwithstanding clauses work in practice.

Change Control And Variation (How You Adjust The Deal)

Often, the best commercial outcome isn't "pause everything" - it's "adjust the scope and keep going".

That might mean swapping materials, revising deadlines, changing delivery methods, or agreeing a new milestone plan. If your contract has a clear variation process, you can document those changes quickly and reduce the risk of disputes later.

That's where a proper approach to contract amendments becomes extremely helpful - especially during fast-moving disruptions.

Common Force Majeure Mistakes (And How To Avoid Them)

A force majeure clause can be incredibly useful - but only if it's drafted clearly and used correctly.

Here are some common pitfalls we see (and how you can avoid them).

Mistake 1: Using A Generic Template Without Matching Your Real Risks

Template clauses often include a long list of events, but they don't reflect the specific way your business operates.

For example:

• If you're an online service provider, you may care more about cloud outages and cyber incidents than floods.
• If you're in imports/exports, you may care about sanctions, border issues, and currency/payment disruption.
• If you run events, you'll want clarity on venue shutdowns, safety restrictions, and cancellation timelines.

Your contracts should reflect your actual dependencies - not generic "legal sounding" wording.

Mistake 2: Being Too Vague (So You End Up Arguing About Meaning)

Clauses that rely on broad phrases like "anything outside our control" without defining consequences can lead to disputes about:

• whether the event qualifies,
• whether performance is genuinely prevented,
• how long suspension lasts, and
• what the parties must do next.

If the clause is likely to be used in high-stakes situations, you want it to be as operational as possible - almost like a mini crisis-management plan built into the contract.

Mistake 3: Forgetting About Notice (And Losing Protection)

Even if an event clearly qualifies, failing to give notice correctly can mean you can't rely on the clause.

Practical tip: set up an internal process so that if a disruption happens, someone is responsible for checking contracts and sending notices immediately (and keeping written records).

Mistake 4: Assuming Force Majeure Automatically Ends The Contract

Many clauses suspend obligations first, and only allow termination after a defined period.

If you need the right to exit sooner (for example, because the deal is time-sensitive), you should negotiate that upfront. If you're relying on a clause that doesn't exist, you could be the one in breach.

Mistake 5: Not Aligning The Clause With Your Customer Promises

If you sell to consumers, you need to be especially careful that your contract terms and policies match what you're promising on your website and in marketing.

Even for B2B, the same "alignment" principle applies: if your sales team is promising delivery by a fixed date "no matter what", but your contract tries to give you a broad force majeure escape route, you're setting your business up for conflict internally and externally.

Mistake 6: Treating Force Majeure As A "Free Pass" Instead Of A Cooperation Tool

Force majeure clauses often work best when they encourage cooperation - sharing information, mitigating impact, and working toward a revised plan.

If you draft a clause that's too one-sided, it might look attractive initially, but it can make negotiations harder and damage long-term relationships.

A balanced clause is usually the most commercially effective clause.

Key Takeaways

• A force majeure clause is a contract term that sets out what happens when an external event outside a party's reasonable control prevents or delays performance.
• In the UK, force majeure protection usually depends on your contract wording - you shouldn't assume you can rely on general law if the clause is missing or unclear.
• A strong force majeure clause should define qualifying events, require prompt notice, include mitigation obligations, and clearly explain suspension, extensions, payment consequences, and termination rights.
• Force majeure needs to work alongside other key clauses like limitation of liability, termination rights, and variation mechanisms, so the contract doesn't contradict itself.
• Common mistakes include using generic templates, vague drafting, missing notice requirements, and failing to align the clause with how your business actually delivers goods or services.
• Getting the clause right from day one can prevent disputes, protect cashflow, and keep valuable commercial relationships intact when the unexpected happens.
