Contracts keep your business moving - they secure supply, set expectations with customers and partners, and allocate risk. When one party doesn’t do what they promised, you may be entitled to “damages” (financial compensation) to put your business in the position it would have been in if the contract had been properly performed.
In this guide, we’ll break down what breach of contract damages are under UK law, how they’re calculated in real life, common limits that can reduce what you can recover, and the steps to take if you need to make a claim. We’ll also share drafting tips to help you protect your position from day one.
What Counts As A Breach Of Contract?
A breach of contract happens when a party doesn’t meet a contractual obligation without a valid legal excuse. For most business-to-business (B2B) agreements, that means you’ll usually need to show four things:
- There is a valid contract (written, verbal, or a mix - though written is best).
- The other party had a clear obligation (for example, to deliver goods by a date, pay an invoice, or meet a service standard).
- They failed to meet that obligation (late, defective, or non-performance).
- Your business suffered loss because of that breach.
The breach could be “repudiatory” (so serious it justifies termination) or “non‑repudiatory” (less serious, but still gives rise to compensation). The label matters because it affects your remedies: in serious cases, you might be able to terminate and claim damages. In smaller breaches, your remedy is usually damages while the contract continues.
Importantly, most claims turn on loss - not just that the other side slipped up, but that you can prove a financial impact. That’s where damages come in.
What Damages Can Your Business Claim?
Damages are designed to compensate, not punish. UK contract law focuses on putting you, so far as money can do it, in the position you would have been in if the contract had been performed properly. In practice, you might pursue the following categories.
Expectation (Loss of Bargain) Damages
These aim to give you the “benefit of the bargain.” Typical examples include:
- Lost profit on a resale because a supplier delivered late or not at all.
- The difference between the contract price and the market price when you had to “cover” by buying elsewhere.
- The cost to cure defective performance (e.g. hiring another contractor to fix poor work).
Reliance (Wasted Expenditure) Damages
If expectation loss is hard to prove, you may claim reasonable costs you incurred relying on the contract proceeding (e.g. marketing spend, set‑up costs), provided those costs weren’t likely to be recouped anyway and weren’t too remote.
Restitution (Unjust Enrichment)
In some cases, the law compels the other party to give back a benefit unjustly retained (for instance, money paid for services never provided). This isn’t about your loss, but their gain.
Liquidated Damages (Pre‑Agreed Sums)
Many contracts include a “liquidated damages” clause - a genuine pre‑estimate of loss for specific breaches (common in delivery delays or service‑level shortfalls). If the amount is a reasonable estimate and not a punishment, it’s usually enforceable. If it’s a penalty designed to deter breach, it risks being struck out.
Interest And Late Payment
You can often claim interest on unpaid sums, either under the contract or (for qualifying B2B invoices) under the Late Payment of Commercial Debts (Interest) Act 1998. Check your contract for interest terms and any credit control processes you must follow first.
When Damages May Not Be Enough
Sometimes money isn’t an adequate remedy - for example, where you contracted for a one‑off, unique item, or need someone to stop doing something. In those cases, you might look at additional remedies like specific performance or injunctions, but these are exceptional and depend on the facts.

How Are Breach Of Contract Damages Calculated In Practice?
Courts and arbitrators look for a reasonable, evidence‑based calculation. The goal is not mathematical perfection, but a fair assessment of loss caused by the breach that was reasonably foreseeable. Here’s how that plays out in common scenarios.
1) Supplier Fails To Deliver Stock
You contracted to buy 1,000 units at £10 each, planning to sell at £20. The supplier doesn’t deliver. You “cover” by buying the same stock at £14. Your expectation loss might include:
- Cover cost difference: £4 x 1,000 = £4,000.
- Extra logistics or expediting costs caused by the breach (if reasonable).
- Potential lost profit if you can show lost sales you couldn’t replace in time.
2) Services Performed Defectively
A contractor delivers a sub‑standard website that doesn’t meet agreed specs. You hire another developer to fix it at a reasonable market rate. Your loss is typically the cost of remediation, plus any directly resulting losses (e.g. re‑launch costs) that were foreseeable at the time of contracting.
3) Customer Doesn’t Pay
If a client fails to pay an undisputed invoice, your primary loss is the unpaid sum plus contractual or statutory interest. Where the non‑payment causes additional foreseeable loss (for example, irrecoverable third‑party fees incurred solely because of the breach), you may include those if they’re adequately evidenced.
4) Reliance Loss Where Profit Is Uncertain
If lost profits are too speculative (e.g. a new channel launch with no track record), you might instead claim reliance damages - reasonable marketing, training, and pre‑launch outlays wasted due to the other party’s breach. You’ll still need to show those costs were caused by the breach and not likely to be recovered anyway.
Evidence Is Everything
Keep a clean paper trail. At minimum, gather:
- The contract, statement of work, change orders, and any amendments or addenda.
- Emails, messages, delivery notes, quality reports, and meeting notes.
- Quotes and invoices for cover purchases or remedial work.
- Sales data and forecasts supporting a loss‑of‑profit calculation.
- Time records and expense logs for wasted internal resource.
The stronger your evidence, the better your position to negotiate a settlement quickly - and the more likely you’ll succeed if the matter goes to court.
Limits On Recovering Damages (And How To Navigate Them)
Even where there’s a clear breach, certain legal and contractual limits can reduce or defeat a damages claim. It’s important to map these early so you can set realistic expectations and strategy.
Mitigation
You have a duty to take reasonable steps to reduce your loss. That might include sourcing replacement goods, switching suppliers, or taking interim measures to contain damage. If you fail to mitigate, you may not recover losses you could reasonably have avoided.
Foreseeability (Remoteness)
Only losses that were within the reasonable contemplation of both parties when the contract was made are recoverable. In simple terms: you can usually recover losses that naturally flow from the breach, and unusual or special losses only if the other party knew (or should have known) about the particular risk at the time.
Exclusion And Limitation Clauses
Most commercial contracts include clauses that cap or exclude certain heads of loss (for example, “no indirect or consequential loss,” or a cap equal to 12 months’ fees). These clauses are often enforceable in B2B deals if they’re reasonable and clearly drafted.
It’s good practice to understand how your cap works and which losses are carved out (e.g. IP infringement, data protection breaches). For a deeper primer, see limitation of liability clauses and some practical examples of limitation of liability clauses.
Reasonableness And Fairness Controls
In B2B contracts, the Unfair Contract Terms Act 1977 (UCTA) can make certain exclusions or limitations unenforceable unless they’re reasonable, considering factors like bargaining power and availability of insurance. In consumer contracts, the Consumer Rights Act 2015 imposes additional fairness tests.
Penalty Rule vs Liquidated Damages
Pre‑agreed sums are enforceable if they protect a legitimate business interest and are proportionate to that interest. If a clause is drafted as a punishment or deterrent rather than a genuine estimate of loss, a court may refuse to enforce it.
Notice And Time Bars
Some contracts require you to notify claims within a set period (e.g. “within 20 business days of becoming aware of the breach”) or to follow a tiered dispute process before issuing proceedings. Missing these steps can jeopardise your claim, so check the small print early.
Limitation Periods
Under the Limitation Act 1980, you generally have six years from the date of breach to bring a claim (or twelve years for deeds). That said, many contracts include shorter contractual limitation periods, so always check your agreement.
How To Pursue A Damages Claim (Step By Step)
Before rushing to court, most businesses resolve breach issues commercially. Here’s a pragmatic process that keeps costs proportionate.
1) Assess The Contract And Evidence
Confirm the obligation, the breach, the loss, and any relevant caps, exclusions, notice provisions and time bars. Pull together your documents and numbers so you’re clear on what you’re asking for and why.
2) Send A Clear Letter Before Action
Set out the breach, the losses claimed with a reasonable calculation, and what you want (payment, remediation, or both). Keep it professional and give a sensible deadline to respond. If you need a starting point, here’s how to structure a breach of contract letter before action.
3) Explore Commercial Resolution
Most disputes settle quickly once expectations are clear. Consider a without‑prejudice meeting or mediation. Where you reach agreement, document it in a binding Deed of Settlement so the dispute is finalised and releases are properly captured.
4) Issue Proceedings If Needed
If talks stall, consider a claim through the County Court or High Court depending on value and complexity. Many smaller claims can be started via Money Claim Online. The track allocation (small claims, fast track, multi‑track) will influence procedure and recoverable costs.
5) Keep Proportionality In Mind
Litigation can be time‑consuming. Weigh the claim value against legal spend, management time, and the relationship impact. Sometimes a pragmatic discount settlement is the best commercial outcome.
Reduce The Risk Upfront: Drafting Contracts That Protect You
The best time to “win” a damages claim is before any dispute arises - by agreeing clear terms that manage risk and make recovery straightforward. A few drafting priorities:
Use Clear Performance Standards
Ambiguity creates disputes. Define deliverables, acceptance tests, milestones, service levels and timelines in a statement of work. Be specific about quality standards and what happens if they’re not met.
Include Sensible Liability Caps And Carve‑Outs
Agree a cap that reflects price, risk, and insurance. Carve out non‑negotiables (e.g. death/personal injury from negligence, fraud) and any risks that should sit outside the cap. Ensure exclusions (like “indirect loss”) are balanced with remedies that actually work in practice.
Consider Liquidated Damages For Predictable Risks
For measurable outcomes (delivery delays, uptime shortfalls), pre‑agreed sums can avoid arguments later - provided they’re a genuine estimate and not a penalty.
Build In Notice, Cure, And Dispute Steps
Short cure periods drive prompt fixes, while tiered escalation (project manager → senior execs → mediation) can resolve issues without court. Make notice requirements practical so you don’t accidentally time‑bar your own claims.
Update Contracts Properly
When things change, record it formally via an amendment or side letter rather than relying on email threads. Following a clean process for amending contracts reduces scope creep and disputes over what was agreed.
Get The Documents Drafted And Reviewed By A Lawyer
Templates can miss critical risk points. A tailored agreement and a quick legal check before you sign can save major headaches. If you’re locking in an important deal, consider a Contract Review or bespoke Contract Drafting to ensure your risk position matches your commercial aims.
Frequently Asked Questions About Breach Of Contract Damages
Can I Claim For “Indirect” Or “Consequential” Loss?
It depends on the wording of your contract and what losses were reasonably contemplated at the time of contracting. Many contracts exclude these categories, so check your liability clause before assuming they’re recoverable.
What If The Other Party Says My Losses Are “Too Remote”?
You’ll need to show the losses flow naturally from the breach, or that the other party knew about the special risk when you made the contract (for example, you told them a missed delivery would cause a specific, high‑value event to fail). Documenting these dependencies early can make a big difference later.
Do I Have To Give The Other Side A Chance To Fix It?
Many contracts require it. Even if not, offering a reasonable opportunity to cure can be sensible - it may reduce your loss (mitigation) and improve your position in negotiations or in front of a judge.
Can I End The Contract And Claim Damages?
Only if the breach is serious enough (repudiatory) or your contract allows termination for that type of breach. If you do terminate, do it carefully and in line with the contract - wrongful termination can itself be a breach. If the relationship is simply unworkable, explore a structured exit documented in a deed, alongside settlement terms.
What If The Contract Has A Liquidated Damages Clause?
If it’s a genuine pre‑estimate of loss, that sum will usually apply instead of a separate damages calculation for that breach. If it looks like a penalty, it may be unenforceable and you’d fall back to ordinary damages.
Key Takeaways
- Damages aim to compensate your business for loss caused by a breach, not punish the other side - expectation, reliance and restitution are the main categories.
- Prove your numbers: gather contracts, change orders, quotes, invoices and sales data to support a fair, evidence‑based calculation.
- Expect limits: mitigation, foreseeability, exclusion and limitation clauses, notice requirements and limitation periods can all reduce what you recover.
- Start commercial: a well‑pitched letter before action and sensible negotiation often resolve disputes faster and cheaper than court.
- Protect yourself upfront: use clear scopes, proportionate caps, workable remedies and, where suitable, liquidated damages - and keep your terms current via proper amendments.
- When it matters, get help: a targeted Contract Review or tailored Contract Drafting can prevent disputes - and a binding Deed of Settlement can put them to bed.
