UK Landlord Unfair Terms Remedies: What Tenants Can Do

The Consumer Rights Act 2015 replaced the older Unfair Terms in Consumer Contracts Regulations 1999, but the core test stayed the same. A term is unfair if it creates a significant imbalance in the parties' rights and obligations to the detriment of the consumer, and it wasn't individually negotiated.

Put simply: if the clause gives your landlord broad powers while stripping away your protections, it probably fails the test.

The Act also requires that terms be written in plain, intelligible language. Clauses buried in dense legal text, or written in ways that make it genuinely hard to understand what you're agreeing to, can be challenged on transparency grounds alone.

There's an important carve-out. The 'core terms' of a contract, meaning the rent amount and the main description of the property, can't be assessed for fairness as long as they're transparent and prominent. Everything else is fair game.

One clause that keeps appearing in tribunal claims is the 'professional cleaning' obligation. Many tenancy agreements require tenants to return the property in a 'professionally cleaned' condition regardless of its state at move-in. The Competition and Markets Authority has flagged this type of clause as potentially unfair, and it contradicts the Tenant Fees Act 2019, which prohibits landlords from charging fees not permitted by the Act. If your agreement contains a blanket professional cleaning requirement with a financial penalty attached, that clause is almost certainly unenforceable. Our guide on whether your landlord can charge for cleaning covers this in more detail.

Not every unfair-sounding clause is legally unfair. Courts look at the contract as a whole, the circumstances of the agreement, and how the clause actually operates. That said, certain categories of terms appear repeatedly in tribunal decisions and legal guidance.

Clauses that restrict your right to repairs. Landlords have statutory obligations under the Landlord and Tenant Act 1985 to keep the structure, exterior, and essential services in repair. Any clause that tries to transfer those obligations to the tenant, or that limits the landlord's liability for disrepair, is almost certainly unenforceable (Shelter England, 2025). The property still has to meet the Decent Homes Standard regardless of what the contract says.

Excessive deposit deduction clauses. Clauses that give landlords blanket authority to deduct for 'any damage' without specifying a process or referencing fair wear and tear create an imbalance the Act is designed to address.

Rent review clauses without notice or process. A clause allowing your landlord to increase rent at will, with no notice period or challenge mechanism, is likely unfair. The Renters' Rights Act 2025, which came into effect on 1 May 2026, now governs how rent increases must be handled through the formal Section 13 process. A contractual clause that bypasses this isn't just unfair, it's probably illegal.

No-pet clauses written as absolute prohibitions. From May 2026, landlords can only refuse a pet request on reasonable grounds. A clause that bans pets outright, with no mechanism for a tenant to request permission, may now conflict with statute.

Clauses permitting landlord entry without notice. You have a right to quiet enjoyment. A clause giving your landlord the right to enter whenever they want, without the standard 24 hours' notice, conflicts with that right and is unenforceable.

If any of these sound familiar, keep reading.

The primary remedy under the Consumer Rights Act 2015 is that the unfair term simply doesn't bind you. You can ignore it. If your landlord tries to enforce it, you can defend yourself by pointing to the Act.

But 'ignoring a clause' only works if you're prepared to back it up. Here's what that looks like in practice.

Raise it formally with your landlord first. Write a letter citing the Consumer Rights Act 2015 and specifying which clause you're challenging and why. This creates a paper trail and sometimes resolves things without escalation. Remedy can draft this letter for you, citing the relevant legislation, so you're not starting from a blank page.

Refer the matter to the First-tier Tribunal (Property Chamber). For most disputes about unfair terms in residential tenancies in England, the tribunal is the right venue. It's free to file, and you don't need a solicitor. The tribunal can declare a clause unenforceable and, depending on the claim, award compensation.

Claim damages through the county court. If an unfair clause has caused you a financial loss, such as an unlawful deduction from your deposit or a penalty fee charged under an unenforceable clause, you can claim that money back through the civil courts. The Small Claims Court handles disputes up to £10,000 and is designed to be accessible without legal representation.

Report to the Competition and Markets Authority. The CMA has issued draft guidance on unfair contract terms in consumer contracts and can take enforcement action against landlords or letting agents using systematically unfair terms (Harbottle & Lewis, 2025). This won't get your money back directly, but it creates pressure and can lead to industry-wide change.

Use consumer protection legislation as a parallel route. The Consumer Protection from Unfair Trading Regulations 2008 gives tenants remedies against misleading or aggressive practices, including the right to unwind a contract or claim damages. Our article on tenant remedies for unfair trading practices covers this angle specifically.

Read the process wrong and you'll waste time. Here's the order that works.

Step 1: Identify the clause and name the problem precisely. 'This feels unfair' won't get you far. You need to say: 'Clause 14 requires professional cleaning regardless of the property's condition at move-in, which creates a significant imbalance contrary to s.62 of the Consumer Rights Act 2015 and conflicts with the Tenant Fees Act 2019.' The more specific you are, the harder it is for a landlord or tribunal to dismiss you.

Step 2: Gather evidence. Your signed tenancy agreement is the starting point. Also collect your inventory report, any communications with your landlord about the clause, and photographs of the property's condition. If you're challenging a rent review clause, keep copies of every rent increase notice you've received.

Step 3: Send a formal letter before action. Give your landlord 14 days to respond or remedy the issue. This is a legal requirement before most court claims and a sign of good faith before tribunal proceedings. Remedy's letter drafting tool generates formal letters citing the relevant legislation, which removes the risk of writing something that undersells your claim.

Step 4: File with the tribunal or court if there's no resolution. For property disputes in England, the First-tier Tribunal (Property Chamber) is the starting point. The RENTS1 form is used for rent-related disputes. For deposit deductions under an unfair clause, a deposit scheme adjudicator may be the faster route.

Step 5: Prepare your bundle. Tribunal submissions need to be organised: the agreement, correspondence, evidence, and your legal argument. A disorganised bundle loses cases that should be won.

If you upload your tenancy agreement to Remedy, the platform extracts key terms, flags potential issues, and provides tailored advice based on your specific agreement. That's a faster starting point than reading 30 pages of contract language on your own.

The Renters' Rights Act 2025, in force from 1 May 2026, doesn't directly replace the Consumer Rights Act 2015 framework. The two pieces of legislation work alongside each other.

What the Renters' Rights Act does is tighten the statutory baseline, which means more clauses in existing tenancy agreements now conflict with statute, making them easier to challenge.

The abolition of assured shorthold tenancies and the move to periodic tenancies means any fixed-term clause that attempted to lock tenants in with financial penalties for leaving early now operates in a different legal context. Any clause that tried to replicate the effect of a Section 21 eviction notice, or that gave landlords rights to end the tenancy outside the new statutory grounds, is now unenforceable.

Rent control clauses in agreements that bypass the Section 13 notice process are also affected. Under the new regime, landlords must use Section 13 to raise rent, and tenants can challenge increases at the tribunal. A contractual clause that tries to impose a different, less protective process conflicts directly with the statute. Our guide on how to challenge an unlawful rent increase in the UK explains the Section 13 process in detail.

The Renters' Rights Act also codifies the right to request a pet, as noted above. Any absolute no-pet clause is now legally weaker than it was before May 2026.

The practical upshot: if you signed a tenancy agreement more than a year ago and you're facing pressure from a clause in it, review that clause against both the Consumer Rights Act 2015 and the Renters' Rights Act 2025. The legal position has shifted in your favour.

Deposit disputes are where unfair clause challenges become most financially concrete. The average deposit in London runs to several thousand pounds. A landlord who uses an unenforceable 'professional cleaning' or 'damage restoration' clause to justify withholding part or all of that deposit isn't just being unfair, they may also be in breach of the deposit protection rules.

If your deposit was protected in an approved scheme, such as the Deposit Protection Service, MyDeposits, or the Tenancy Deposit Scheme, the adjudicator will not uphold a deduction based on an unenforceable clause. Submit the tenancy agreement, your move-in inventory, and your move-out photographs. Point to the clause. Argue that it's unenforceable under the Consumer Rights Act 2015. Adjudication is free and usually resolves within 28 days.

If your deposit wasn't protected at all, your remedies are stronger. Under Section 214 of the Housing Act 2004, you can claim compensation of one to three times the deposit amount, on top of getting the deposit back. A £1,500 deposit that was never protected could generate a claim of up to £4,500 plus the original £1,500. Our article on deposit protection violations and how to claim compensation walks through this in full.

Remedy's Landlord Assessment and RRO Eligibility Check covers deposit protection compliance as part of its standard assessment. If your landlord failed to protect the deposit, the platform will flag it and calculate your potential claim value.
