Common Illegal Tenancy Terms and How to Challenge Them

Renting a home in England comes with legal protections designed to keep renters safe and treated fairly. However, some tenancy agreements may include illegal or unenforceable terms, either by mistake or intention. Recognising these terms empowers you to defend your rights and ensure your tenancy complies with the law.

Understanding Tenancy Agreements in England

In England, most renters have an assured shorthold tenancy (AST), covered by the Housing Act 1988. Tenancy agreements set out the rules and rights for both landlord and tenant, but cannot override the law—no matter what your contract says.

What Makes a Tenancy Term Illegal or Unfair?

A term is illegal or unfair if it tries to remove or limit your legal rights, or puts unfair pressure on one party. The Consumer Rights Act 2015 protects renters from unfair contract terms. Key signs a term may be illegal include:

  • It contradicts your basic rights under the law
  • It tries to waive the landlord’s legal responsibilities (such as repairs)
  • It's confusing, hidden in fine print, or uses misleading language
  • It imposes heavy penalties that are disproportionate

Illegal clauses cannot be enforced, even if you have signed the agreement.

Examples of Common Illegal or Unfair Tenancy Terms

  • Waiving the landlord’s duty to repair: For example, a clause saying the landlord is not responsible for repairs to structure or heating is void. By law, landlords must keep these in repair (see Landlord and Tenant Act 1985).
  • Blocking deposit protection: Any clause stating your deposit does not need to be protected in a government scheme is illegal.
  • Trying to avoid notice periods: Agreements that say you can be evicted without proper notice are not valid (official notice periods must be followed).
  • Banning guests or overnight visitors completely: Restricting visitors entirely is usually unfair, unless justified by legitimate concerns like overcrowding.
  • Excessive penalty fees: Large fees for late rent, minor damage, or minor breaches are often unfair. Charges must be reasonable and reflect actual costs.

How to Check Your Agreement

Carefully read your tenancy agreement and compare its terms against your legal rights. Use official resources, such as the government's tenancy agreement guidance for private renters, to spot any questionable clauses.

What to Do If You Spot an Illegal Term

If you think your tenancy agreement contains illegal or unfair terms, you can take action. Here’s what you should do:

  • Talk to your landlord: Flag the term and explain why it's not valid, referencing the law or official guidance.
  • Seek advice: Contact your local council or a recognised service like Citizens Advice.
  • Challenge the term formally: You can raise a complaint if a landlord tries to enforce an illegal term.

Key Official Forms and How to Use Them

  • Form N1 – Claim Form for Money: If your landlord charges you unlawful fees, you can use this County Court form to claim back money owed. Download from the official N1 form page. For example, if you paid an excessive late fee, you can claim it back.
  • Form 6A – Notice seeking possession of a property let on an AST: If a landlord issues a Section 21 notice, it must be on this official form. Find guidance and download it from the official tenancy forms page. If the wrong form is used, the notice may be invalid.
  • Deposit Protection Dispute Forms: If your landlord refuses to protect your deposit or includes clauses to avoid this requirement, use your scheme’s dispute process. For example, with the Deposit Protection Service, follow their official dispute claim process online.
If you believe you are being pressured to accept unfair terms, seek advice early—many local councils have tenancy support teams ready to help.

How Are Disputes Handled? The Tribunal System

In England, disputes about tenancy terms can ultimately be heard by the First-tier Tribunal (Property Chamber). This independent body handles cases about illegal fees, unfair contract terms, and rent issues. If informal talks or complaints don’t resolve your concerns, you can submit your case here for an impartial decision.

Protecting Yourself: Action Steps

  • Review every term in your agreement—don’t rush to sign.
  • Reference official guidance to check for legality.
  • Talk to the landlord if you have concerns; most issues can be resolved informally.
  • If you suffer loss from an illegal term, keep records and seek advice on claiming compensation.
  1. What should I do if my landlord insists on an illegal term?
    Try to discuss the issue with your landlord first—explain your rights with reference to government guidance. If they persist, contact Citizens Advice or your local council for further support, and consider making a formal complaint if needed.
  2. Can my landlord force me to pay for repairs?
    No. Under the law, landlords must keep the structure and essential services (plumbing, heating, etc.) in repair. Tenancy terms trying to shift this responsibility to you are illegal.
  3. Is it legal for my tenancy agreement to ban all visitors?
    Usually not. A complete ban on guests is often seen as unfair and unenforceable unless there is a genuine issue, such as overcrowding.
  4. Where can I challenge unfair fees or charges?
    You can dispute these through the First-tier Tribunal (Property Chamber) or seek a refund via the county court with Form N1. Seek advice before starting legal action.
  5. Can I ignore an illegal term if I've signed the contract?
    Yes. Even if you sign, the law overrules any illegal or unfair clause, so those terms cannot be enforced against you.
