Key Takeaways
- A warranty in UK contract law is a promise within an agreement that certain facts are true or conditions will be met. If breached, it usually entitles the other party to claim damages—not to end the contract.
- Understanding the difference between a warranty, condition, and representation is essential. Each has different legal consequences, so always check which terms apply in your contracts.
- Breach of a warranty typically limits your remedy to compensation for losses—termination is not automatic.
- Poorly drafted warranty clauses expose your business to risks, disputes, and unenforceable rights. A robust clause can save you significant time and money.
- Express warranties are those you negotiate; implied warranties, like those under the Sale of Goods Act 1979, may protect your interests even if unwritten.
- Clear, well-written warranty clauses prevent misunderstandings, define liability, and simplify disputes.
- Our platform provides automated contract review and lawyer-drafted templates, ensuring your business gets warranties right and stays protected.
- Go-Legal AI helps you build and review warranty clauses so your contracts are robust, compliant, and tailored to UK law.
- Go-Legal AI is rated Excellent on Trustpilot with 170+ five-star reviews from UK startups and SMEs.
What Is a Warranty in UK Contracts? Plain-English Definition & Why It Matters
Navigating the legal fine print in business contracts can be daunting—especially when it comes to warranties. If you’re asking, “What is a warranty, and does it really protect me?” you’re not alone. Many owners and founders feel exposed to risk due to unclear warranty clauses or simply trip up on the legal jargon.
A warranty in UK law is a contractual promise about a fact or outcome—such as “the product meets all agreed specifications.” It’s not just window-dressing: the wording and placement of a warranty can decide whether you’re eligible for compensation if the other side lets you down. Weak or generic wording leaves your rights—and your cash flow—totally exposed.
A Cardiff-based web agency, “Pixel Dash Ltd”, buys software with a warranty that it’s free from viruses. If it turns out the software contains malware, the agency can claim damages for lost work but likely can’t cancel the contract altogether.
Our platform’s contract review scans your agreements for warranty terms in seconds—so you’re never left exposed.
Warranty vs Condition vs Representation: Key Differences That Impact Your Rights
Confusing “warranty”, “condition”, and “representation” is a common (and costly) mistake. Each shapes what happens when a promise is broken.
- Condition: A core term. If breached, you can usually end the contract and claim damages.
- Warranty: A secondary term. Breach lets you claim compensation, but not terminate the contract.
- Representation: A statement made to induce the contract. If it turns out false, you may have limited remedies for misrepresentation.
| Term | Definition | When It Applies | Remedies for Breach | Example |
|---|---|---|---|---|
| Condition | Essential promise at contract’s core | At contract formation | End contract + claim damages | Delivery date for vital goods |
| Warranty | Promise about facts or performance | At or after formation | Damages claim (contract continues) | Goods match specification |
| Representation | Pre-contract statement to persuade you | Before contract formation | Misrepresentation: possible rescission | “Our company’s IP is fully owned” |
A design agency contracts to supply artwork. The client’s claim that “all supplied images are copyright-cleared” is a representation. Once restated in the contract’s warranties section, it becomes a warranty: if it turns out to be false, you can sue for losses.
Always clarify if each statement is a condition, warranty, or representation—uncertainty leads to confusion and increased risk.
If you’re unsure which is which, our contract review tool instantly highlights conditions, warranties, and representations for you.
Express, Implied & Statutory Warranties: Know Your Contract Protections
There’s more than one way a warranty can exist in your contract:
1. Express Warranties
These are directly negotiated and written into the contract—such as assurance that goods are fit for purpose or that intellectual property is owned outright.
2. Implied Warranties
Even without written words, UK law automatically inserts some warranties. If you buy equipment, the Sale of Goods Act 1979 says it must be fit for normal use—even if your supplier says nothing.
3. Statutory Warranties
- Sale of Goods Act 1979: Goods must match their description and be of satisfactory quality.
- Supply of Goods and Services Act 1982: Services must be delivered with reasonable care and skill.
- Consumer Rights Act 2015: Tightens warranty protections for consumers—businesses can’t easily limit these.
For B2B deals, you may be able to limit some implied warranties, but only if it passes the “reasonableness” test under the Unfair Contract Terms Act 1977.
A Bristol tech startup buys laptops. The supplier’s contract is silent about quality, but it’s still covered by statutory warranties: if the laptops are faulty, the company can claim repairs or money back.

Essential Elements: What to Include in a Warranty Clause (Checklist)
A robust business contract should always specify:
| Component | What It Does | Why It Matters |
|---|---|---|
| Accuracy | Confirms facts/statements (e.g., finances) are correct | Reduces risk of costly disputes |
| Materiality | Filters out trivial breaches | Focused, effective claims process |
| Knowledge qualifiers | Limits liability to known facts | Prevents unreasonable exposure |
| Duration/Limitations | Sets how long claims can be made | Stops “open-ended” legal risk |
| Financial caps/baskets | Sets max claim level and minimum claim size | Predictable, manageable exposure |
| Disclosure provisions | Lists exceptions | Prevents unfair “gotchas” |
| Clear remedies | Details options for breach (damages, repair, etc.) | Prevents legal wrangling |
Use a disclosure letter—a formal list of known issues given before the contract is signed. This protects both sides from unexpected claims and keeps buyers informed.

What to Do If a Warranty Is Breached in a UK Contract
Breach of a warranty unlocks your right to compensation, not contract termination—unless the clause states otherwise. Handling it well protects both your business and valuable relationships.
Practical Steps If You Suspect a Warranty Breach
- Identify the Clause: Locate the warranty at issue and check any relevant disclosure letters.
- Assess the Breach: Decide whether the claim is material (significant) or trivial.
- Gather Evidence: Keep records—emails, contracts, invoices—which demonstrate loss.
- Notify the Other Party: Formally explain the breach, referencing specific evidence and losses.
- Limit Your Loss: Take prompt, practical steps to prevent further harm (a legal requirement to mitigate).
- Value Your Claim: Work out damages using agreed limitation periods and caps.
- Try to Resolve: Open negotiation or mediation before escalating.
- Expert Input: If resolution fails, get a contract reviewed by one of our on-demand legal experts.
A consultancy buys market data on the warranty that it’s accurate to within 1%. When the data proves misleading, and the client loses sales, the consultancy claims damages backed by the warranty clause.
Act quickly—limitation periods are often as short as 12 months. Missing the deadline means you lose your right to claim.

Step-by-Step: How to Draft & Review Robust Warranty Clauses
A strong warranty clause does not come from copying templates or legal jargon. Business owners should:
- Be Specific: State precisely what is warranted—avoid catch-all language.
- Use Materiality & Knowledge Limits: Only promise what you truly know and what matters to the business.
- Define Duration: Spell out exactly how long each warranty is valid.
- Incorporate Agreement Clauses: Make it clear the contract (and disclosure letter) are the final word.
- Negotiate Financial Caps & De Minimis: Protect your bottom line with maximums and minimums for claims.
- Outline Remedies: Don’t assume damages—define what happens if something fails.
Sample Warranty Clause Snippets
Goods Sale:
“The Seller warrants that, as of delivery, the Goods meet all agreed specifications and are free from third party claims.”
Plain-English Note: This is a specific promise about product quality and legal title.
Services:
“The Provider warrants that all services will be carried out with due skill and care, and in line with industry standards.”
Plain-English Note: Sets out a measurable, industry-standard promise.
Software/SaaS:
“The Vendor warrants the Software is free from viruses and does not infringe any third party rights.”
Plain-English Note: Protects the buyer against IP and operational risks.
A SaaS business reassures its clients by including a warranty for GDPR compliance—boosting trust and providing clear remedies for misuse.

Statutory Implied Warranties: The Sale of Goods Act 1979 & Supply of Goods and Services Act 1982
UK law inserts “implied terms” into contracts regardless of what you write:
- Sale of Goods Act 1979 (SGA):
- Goods must be of satisfactory quality and match their stated description.
- Goods must be fit for any purpose specified by the buyer.
- Supply of Goods and Services Act 1982 (SGSA):
- Services must be delivered with reasonable care and skill.
- If no date is agreed, services should be provided in a reasonable time.
- The price must be reasonable if not set.
Can You Exclude Implied Warranties?
- For Consumers: Implied terms cannot generally be excluded (Consumer Rights Act 2015).
- For Businesses: You can exclude or limit some implied warranties, but only if the restriction is reasonable under the Unfair Contract Terms Act 1977 (UCTA). Any attempt to exclude liability for death or personal injury is always void.
A manufacturing startup omits any quality obligations in its supply contract hoping to escape liability if things go wrong. Under the Sale of Goods Act, buyers still have a statutory right to goods that work as intended.
Don’t assume silence in your contract protects you. Statutory warranties might still bite—always check, clarify, or limit as needed.
Our platform checks contracts for hidden statutory terms and flags anything that might increase your risk.
Warranty vs Indemnity in Contracts: What’s the Difference?
While both warranties and indemnities offer protection, they work very differently.
- Warranty: A promise about facts. If broken, you must prove your loss and then claim damages.
- Indemnity: An explicit promise to cover specific losses—often broader and less dependent on showing direct loss.
| Warranty | Indemnity | |
|---|---|---|
| Remedy | Damages for proven loss | Repayment for specified loss |
| Proof Required? | Yes—actual loss must be shown | Not always—can cover indirect loss |
| Typical Uses | Product defects, data accuracy | IP claims, third-party fines |
A recruitment agency “TalentFlow Ltd” supplies a contractor who turns out not to have a right to work in the UK. The agency’s warranty covers the fact, but its separate indemnity means it must also pay any fines—even if the client didn’t suffer direct loss.
Indemnities can mean much larger claims than warranties—negotiate their scope carefully and always align with your business risk.
Use our guided templates to ensure your indemnity and warranty clauses do exactly what you intend—nothing more, nothing less.
Avoiding Costly Mistakes: Common Warranty Pitfalls for UK Businesses
Too many businesses trip over avoidable mistakes when using warranties. Beware of:
- Relying on generic “boilerplate” warranties that ignore your sector risks.
- Missing out knowledge or materiality limits—leaving you open for unknown issues.
- Forgetting limitation periods—risking endless liability.
- Failing to detail remedies, relying instead on uncertain legal assumptions.
- Not demanding or providing a disclosure letter before completion.
How to Sidestep These Risks
- Always edit warranty clauses to match your deal, not just your sector.
- Add clear “to the best of Seller’s knowledge” statements where you might not know the facts.
- Specify exactly how long each warranty survives after the contract.
- Use disclosure letters as a normal practice in business, especially acquisitions.
- Make sure every warranty clause spells out what happens if things go wrong.
- Regularly review supply and customer contracts—laws and business needs change.
A fintech startup fails to limit the warranty duration in its procurement contracts. Six years later, it faces a large, unexpected claim for a minor software flaw—easily avoidable with a simple duration clause.

Frequently Asked Questions
What is the difference between express and implied warranties?
Express warranties are written directly into your contract, clearly stating what is promised (e.g., “the goods are new”). Implied warranties arise automatically—like the legal requirement that goods must be satisfactory—whether your contract mentions it or not.
Can I exclude implied warranties in a B2B contract?
You can sometimes limit or exclude implied warranties in business-to-business contracts, but only if this restriction is reasonable under the Unfair Contract Terms Act 1977. You cannot exclude liability for death or personal injury caused by negligence.
How do I spot a warranty clause in a legal contract?
Look for headings like “Warranties”, “Seller’s Warranties”, or “Provider’s Warranties”. These sections detail promises about quality, legal ownership, or compliance. Use our review tool to highlight all warranty terms instantly.
What remedies are available if a warranty is breached under UK law?
The usual remedy is damages—claiming for actual financial losses suffered. You generally cannot terminate the contract solely due to a warranty breach, unless the contract specifically gives you that right.
Are warranties always legally binding in contracts?
Yes. If a warranty is included as a contractual term and the contract has been properly formed, it is legally binding and fully enforceable under UK law.
What is a disclosure letter and how does it affect warranties?
A disclosure letter details any known exceptions before the deal is signed. It prevents claims for those specific matters and gives both sides a clear understanding of risk.
When should I use a warranty instead of a condition or representation?
Use a warranty for important but non-fundamental promises—like confirmation of minor product specs or that IP is original—so you retain the right to claim damages, but do not want to end the contract over small issues.
How can I negotiate better warranty terms?
Limit the warranty’s scope (using knowledge or materiality qualifiers), define limitation periods, cap your financial exposure, and insist on a disclosure letter when needed. Tailor every warranty to your transaction’s value and your company’s appetite for risk.
What’s the difference between a warranty and an indemnity in a contract?
A warranty is a promise about a specific fact, with damages as the remedy; an indemnity is a promise to cover identified losses, usually allowing faster and broader claims for compensation.
Do warranty clauses need to be specific to be valid?
While not required, the more specific and detailed the warranty, the easier it is to claim if things go wrong and the less likely you are to have disputes.
