How to Challenge Unfair Terms in Mis‑Sold Contracts

Consumers in England and Wales are protected by statutory rights when entering contracts with businesses. If you believe a contract you signed contains unfair terms or you were mis‑sold into agreeing terms that disadvantage you, the law provides mechanisms to challenge those terms. This guide explains what constitutes an unfair term, the legal framework that protects consumers, and the practical steps you can take to challenge unfair terms and pursue remedies. It is written to be understandable for members of the public while remaining accurate and precise for solicitors and students.

Understanding Unfair Terms in Consumer Contracts

What Is an Unfair Term?

An unfair term in a consumer contract is a term that, contrary to the requirement of good faith, causes a significant imbalance in the rights and obligations of the trader and the consumer to the consumer's detriment. Businesses cannot enforce such terms against consumers. The test of fairness is applied by courts and tribunals on the wording of the term, how it could be used, and the circumstances at the time the contract was agreed.

For example, a clause that allows a seller to increase the price after you have agreed the contract without justification or that imposes excessive cancellation charges may be considered unfair.

Legal Framework

The principal law governing unfair terms in consumer contracts is the Consumer Rights Act 2015. This Act:

• Applies to consumer contracts entered into on or after 1 October 2015.
• Incorporates a fairness and transparency test that courts use to decide whether a term is unfair.
• Provides that unfair terms are not binding on consumers.

Earlier contracts entered into before 1 October 2015 may be governed by the Unfair Terms in Consumer Contracts Regulations 1999, which the Consumer Rights Act effectively replaced.

A contract term is not automatically unfair merely because it favours the trader; it must be shown to create a significant imbalance and be contrary to good faith.

Identifying Potentially Unfair Terms

Common Examples

Terms likely to be unfair include those that:

• Allow unilateral variation of key contract terms such as price or service characteristics.
• Impose disproportionate penalties or cancellation fees.
• Strip away consumer rights or limit the trader's liability beyond what is reasonable.
• Are written in complex or unclear language that obscures their meaning.

These examples align with guidance provided by the Competition and Markets Authority (CMA) and government regulators.

Blacklisted Terms

Certain terms are effectively blacklisted and unenforceable in all circumstances, such as those excluding liability for death or personal injury caused by negligence.

Step‑by‑Step: How to Challenge an Unfair Term

1. Review Your Contract Carefully

Start by identifying the specific term you believe is unfair. Note:

• The exact wording of the term.
• How and when you agreed to it.
• How it affects your rights or obligations under the contract.

Terms must be transparent and in plain language. If they are not, that may support an argument that they are unfair.

2. Raise a Formal Complaint with the Trader

Write to the business that supplied the contract:

• Clearly explain why you believe the term is unfair, referring to the relevant legal basis (e.g. Consumer Rights Act 2015).
• Request that the term is not enforced against you or that you are compensated for detriment caused by the term.

Giving a trader the opportunity to respond can help resolve the issue without court action.

3. Report the Term to Regulators

If the trader will not amend or remove the term:

• You can report the issue to the Competition and Markets Authority (CMA). The CMA has powers to investigate and seek enforcement action against unfair terms.
• You can also contact your local Trading Standards office for support.

Regulators may act to prevent the use of the term against all consumers.

4. Consider Legal Action

If informal resolution and complaints to regulators are unsuccessful, you may decide to take legal action:

• You can bring a claim in the county court or small claims court asserting that the term is unfair and should not be enforced against you.
• If a trader is seeking to enforce an unfair term against you (for example demanding payment under it), your defence can be that the term is unenforceable.

For monetary disputes under £10,000, small claims procedures may be appropriate; above that, higher courts may have jurisdiction.

Time Limits and Practical Considerations

Limitation Periods

There are strict time limits for bringing legal claims:

• Generally, claims based on breach of contract or unfair terms must be started within six years from the date the contract was breached.
• If the issue was not immediately apparent, the limitation period may run from when you became aware of the unfair term.

Missing the limitation period can prevent you from pursuing a claim. Always act promptly once you identify an issue.

Evidence and Documentation

Keep records of:

• The contract and all correspondence.
• Promotional materials or representations made before you signed.
• Any financial loss or detriment you suffered.

These can support your complaint or court case.

Seek Specialist Advice

For complex situations, especially those involving significant sums or regulated sectors (e.g. financial services), consider consulting a solicitor or consumer law specialist early in the process.

Common Questions from our Readers

Can every term in a contract be challenged?
No. Terms that define the main subject matter of the contract or clearly set the price are generally not subject to the fairness test if they are transparent and prominent.

What happens if a term is found to be unfair?
An unfair term is not binding on the consumer. The rest of the contract continues to operate if it makes sense without that term.

Can I claim compensation?
If an unfair term has caused financial loss or detriment, you may seek compensation through a court or dispute resolution process.

Summary

Consumers in England and Wales can challenge unfair terms in mis‑sold contracts under the Consumer Rights Act 2015. A term is unfair if it causes a significant imbalance in rights and obligations to a consumer's detriment and fails the fairness and transparency test. To challenge a term:

1. Review and document the term and how it affects you.
2. Raise a formal complaint with the trader.
3. Report the term to regulators such as the CMA or Trading Standards.
4. Consider legal action if the term is enforced against you.

Act promptly and keep thorough records, and consider specialist legal advice for complex or high‑value disputes.
