Comprehensive guide to breach of warranty in UK contract and consumer law. Learn what warranties are, how breaches arise, differences from conditions, remedies like damages or statutory rights, and practical steps for claims and dispute resolution in England and Wales.

A breach of warranty is a legal issue that arises when a promised assurance in a contract is not fulfilled. In the context of consumer and commercial contracts in England and Wales, warranties play a specific role and the law treats their breach differently from failures of conditions or other contractual terms. This guide explains what warranties are, how breaches arise, what remedies are available, and how your rights operate in practice under modern UK law.
What Is a Warranty in Contract Law?
In contract law, a warranty is a promise or guarantee within a contract that a particular fact, standard or condition is true or will be met. It might be express (clearly written into the contract) or implied by statute or common law. Unlike a condition - a fundamental contractual term - a warranty is a lesser term that does not go to the root of the contract.
For example, in a supply contract a seller might promise that goods will conform to specific technical standards. If that promise is not honoured, a breach of warranty may have occurred.
1. Types of Warranties
Express Warranties
These are specific promises set out in the contract itself. For instances:
- A written guarantee that goods will function for a set period;
- A service provider's assurance about performance levels.
If these promises are broken, that constitutes a breach of warranty.
Implied Warranties
Some warranties are implied by law even if not written in the contract. In consumer contracts, UK statutory law such as the Consumer Rights Act 2015 provides implied rights that goods:
- Are of satisfactory quality;
- Are fit for purpose; and
- Match their description.
Defects in these respects can amount to a breach of an implied warranty or term.
2. What Constitutes a Breach of Warranty?
A breach of warranty occurs when:
- A party fails to fulfil a promised assurance in the contract; or
- A promised standard (express or implied) is not met during performance.
Unlike breaches of conditions, which may allow a contract to be terminated, a breach of warranty typically does not allow termination by itself. Instead, the primary remedy is a claim for damages - compensation for losses caused by the breach.
Examples of Breach of Warranty
- Goods delivered to a buyer do not meet the quality expressly warranted.
- A service provider's guarantee about system uptime in an IT contract is not met.
- A promised specification of parts or materials is incorrect or untrue.
3. Consequences of a Breach of Warranty
Damages (Compensation)
The most common legal remedy is damages. This means the innocent party may seek a financial award to put them in the position they would have been in if the warranty had been true.
This could include:
- The cost of repair or replacement of defective goods;
- The difference in value between what was promised and what was delivered;
- Other losses reasonably caused by the breach (subject to legal limits on remoteness of damage).
In consumer contracts, statutory remedies under the Consumer Rights Act 2015 may also apply and can include refunds or replacement rather than just damages for losses under a warranty framework.
Contract Continues in Force
Because a warranty is not a fundamental term, the contract itself remains valid even after a breach of warranty - unless the contract specifically states otherwise or the breach is so serious that it goes beyond a simple warranty breach.
4. Warranties vs. Conditions: A Key Distinction
The legal consequences of breaching a warranty differ significantly from breaching a condition, which is a core contract term. If a condition is breached, the innocent party may have the right to terminate the contract and claim damages.
In contrast:
- Breach of warranty usually gives the right to damages only;
- You generally cannot terminate the entire contract solely because a warranty is breached.
This distinction is central to understanding how breach of warranty disputes are resolved in the UK.
5. Statutory Warranties Under UK Consumer Law
In consumer contracts for goods and services, UK statute provides implied warranties - legally guaranteed promises that form part of the contract even if not expressly written. Most notably:
- Consumer Rights Act 2015 creates implied terms around quality, description and fitness for purpose;
- Where an implied statutory term is breached, consumers may have rights to repair, replacement, price reduction, or refund depending on the situation.
These statutory rights operate in addition to any express warranty given by a seller or manufacturer. For consumers, statutory rights often offer broader remedies than contractual warranties alone.
6. How to Respond to a Breach of Warranty
If you believe there has been a breach of warranty:
Step 1: Check the Contract Terms
Look carefully at the wording of the warranty in your contract - understanding whether it is express or implied and what obligations it sets out.
Step 2: Gather Evidence
Keep records of correspondence, invoices, descriptions, specifications and any defects or issues. Demonstrating the difference between what was promised and what was delivered strengthens a claim.
Step 3: Identify Remedies Available
Under UK law:
- Damages are the primary remedy for breach of warranty;
- In consumer contexts, statutory remedies may include repair, replacement or refund;
- Other contractual provisions may specify how claims should be made or time limits for action.
Step 4: Communicate with the Other Party
Contact the other party in writing, set out the breach clearly, and request an appropriate remedy (such as compensation or repair).
Step 5: Consider Escalation
If the issue is not resolved, you may consider:
- Alternative Dispute Resolution (ADR);
- A claim in a county court for breach of contract and damages;
- Consulting a solicitor for complex or high‑value disputes.
7. Common Questions About Breach of Warranty
Does a breach of warranty allow you to end the contract?
No - unless the contract expressly provides for termination on breach of warranty, a breach normally only entitles you to damages while the contract remains in force.
Is a consumer warranty the same as statutory rights?
No - express or extended warranties provided by a seller or manufacturer are additional to statutory rights under consumer protection law. The statutory rights remain enforceable even if a warranty has expired, where appropriate.
How long do you have to take action?
Time limits depend on the type of contract and remedies sought, but under the Limitation Act 1980, most contractual damage claims must be brought within six years in England and Wales. Always check specific contract provisions and statutory limits.
Summary
A breach of warranty occurs when a contractual promise about the condition, quality or performance of goods or services is not fulfilled. In the UK:
- Warranties are less fundamental than conditions, so breach does not usually allow contract termination.
- The primary remedy is damages to put you in the position you would have been in if the warranty had been true.
- In consumer contexts, statutory warranties under the Consumer Rights Act 2015 may offer additional remedies like repair, replacement or refunds.
- Gathering evidence and notifying the other party in writing are essential steps before considering dispute resolution or court action.
Understanding the legal nature of warranties and the consequences of their breach helps you protect your rights, seek appropriate remedies and resolve disputes effectively under UK contract law.
