A clause being written into a contract doesn't automatically make it fair, or even enforceable. UK law has a specific two-part test for this, and it applies whether or not you clicked "I agree."
The two tests every consumer contract term must pass
Under Part 2 of the Consumer Rights Act 2015, a term is unfair if, contrary to the requirement of good faith, it causes a significant imbalance in the parties' rights and obligations to the detriment of the consumer. Separately, Section 68 requires terms to be transparent — expressed in plain, intelligible language and, if written, legible. An unfair term simply isn't binding on the consumer, even if they agreed to it; the rest of the contract can still stand without it.
What "significant imbalance" actually means
Official guidance describes this as a term so weighted in favour of the business that it tilts the contract's rights and obligations significantly in its favour — for example, by granting the trader excessive discretion the consumer has no equivalent power over. Whether a term was actually explained to the consumer before they signed also matters: what a business told (or didn't tell) a customer beforehand can shape whether that same term is later judged fair.
The one narrow exemption — and why it's narrower than people assume
Terms describing the main subject matter or the appropriateness of the price aren't assessable for fairness — but only if they are both transparent and prominent. "Prominent" has a specific legal meaning: brought to the consumer's attention so that an "average consumer" — reasonably well-informed, observant, and circumspect — would actually notice it. A price buried in dense small print doesn't meet this bar, even though price terms are otherwise exempt.
Seven clause types worth checking specifically
- Cancellation fees disproportionate to actual loss — a fee designed to penalise rather than compensate is a strong candidate for unfairness
- Unilateral variation clauses — letting the business change terms without a valid reason stated in the contract
- Broad liability exclusions — the CMA has flagged clauses excluding consequential loss as potentially unfair where they prevent a consumer from getting redress they should have
- Automatic renewal with a short cancellation window — especially where the window isn't clearly flagged
- Clauses shifting the burden of proof onto the consumer — requiring the consumer to prove the business's non-compliance rather than the reverse
- One-sided termination rights — the business can end the contract freely, the consumer cannot
- Any term with more than one reasonable meaning — the law requires courts to adopt whichever interpretation favours the consumer
How to actually use this
- Read termination, liability, and price-variation clauses specifically — these categories draw the most consistent scrutiny
- Check whether a term was ever explained to you before signing, not just whether it appears in the document
- Note whether a clause is genuinely plain language, or written in a way only a specialist would parse quickly
- Remember an unfair term simply doesn't bind you — you don't need to "win" a case for it to be unenforceable, though disputing it in practice may still require pushing back formally
What this means practically
- A term causing a significant imbalance in the business's favour, in bad faith, is not binding on you under the Consumer Rights Act 2015 — regardless of whether you signed or clicked to accept it.
- Price and core subject-matter terms are only exempt from the fairness test if they're both transparent and genuinely prominent — not merely present in the document.
- Ambiguous terms are legally interpreted in the consumer's favour when more than one reasonable reading exists.
- Disproportionate cancellation fees, one-sided termination rights, and broad liability exclusions are the clause types that draw the most regulatory attention.
