Rent increases and fair notice rules in Wales

Rent, Deposits & Increases Wales 4 min read · published August 17, 2026 Flag of Wales

Many renters in Wales face uncertainty when a landlord says they will raise the rent. This plain-language guide explains your rights, the notice a landlord should give, and practical steps tenants can take if a rent rise seems unfair or incorrectly served. It covers fixed-term and periodic tenancies, how to record and respond to written notices, when to negotiate, and when to apply to the First-tier Tribunal (Property Chamber) for a decision. The focus is on clear actions a tenant can take to protect housing stability and finances while using official forms and routes where needed in Wales.

Your rights and types of tenancy

Tenancies are commonly fixed-term (a set period) or periodic (rolling, for example month-to-month). Your tenancy agreement is the first place to check for any rent review clauses. If the agreement is silent, different legal rules apply to periodic tenancies and fixed terms. Landlords must follow the law when proposing a rent rise and give clear written notice so you can consider, negotiate or challenge it.

Keep all rent receipts and written messages about increases in one place.

How rent increases work in Wales

For periodic tenancies landlords commonly use a written proposal or a statutory route under the Housing Act 1988 or other tenancy rules. The Rent Act 1977 still applies to some older tenancies; check which law covers your agreement before taking action.[1][2] If a landlord follows a statutory route and you disagree with the proposed increase, you can ask the First-tier Tribunal (Property Chamber) to decide whether the rise is reasonable.[3]

Respond to any written notice quickly to preserve your right to challenge it.

What to do when you get a rent increase notice

  • Check the notice for a clear date it takes effect and whether it follows the rental period or the tenancy clause.
  • Confirm the notice is in writing and that it identifies the tenancy and the new rent amount.
  • Record and save all evidence: copies of the notice, emails, texts and receipts for previous payments.
  • Contact the landlord or agent to ask for an explanation or to negotiate a different date or amount.
  • If you cannot agree, consider applying to the First-tier Tribunal (Property Chamber) for a decision.

Official forms and notices

There is no single universal "rent increase" form on GOV.UK, but a few official forms and court/tribunal documents are commonly used when disputes or possession actions follow a rent dispute. Below are the main items tenants should know about, with practical examples and where to find the official source.

Section 13 notice (Housing Act 1988)

Form name/number: commonly referred to as a "Section 13 notice" (no single official model form is mandated for private rent increases). When used: landlords use a written notice under section 13 to propose an increase to a periodic tenancy. Tenant example: if you pay monthly rent and your landlord serves a written section 13 notice proposing a higher monthly amount, keep the notice and any reply you send. Official legislation reference is provided below for exact wording on the law and landlord obligations.[1]

Form 6A (accelerated possession under section 21) and court possession claims

Form name/number: Form 6A is used by landlords in some possession procedures; Form N5 is the standard court claim form for possession. When used: if rent disputes escalate and a landlord seeks possession as a result of arrears or the tenancy ending, these court forms may be used. Tenant example: a tenant who disputed an unlawful rent increase but fell into arrears should seek advice and look at the court claim documents to respond promptly if served. Official forms and guidance are available from HMCTS and GOV.UK (see footnotes for links).[4][5]

Keeping a dated log of conversations can make a tribunal case much stronger.

FAQ

Can my landlord increase rent during a fixed-term tenancy?
Generally no, unless your tenancy agreement includes a clear rent review clause that both parties agreed to. If the tenancy is fixed-term and the agreement is silent, the landlord usually must wait until the term ends to propose a change.
How much notice must a landlord give for a rent increase?
Notice should be clear and allow you time to respond; typically landlords give notice at least equal to your rental period (for example one month for monthly rent), but check your tenancy and seek advice if you are unsure.
What if the landlord increases rent without following the correct process?
If a landlord does not follow the proper procedure, you can refuse to pay the extra amount, keep evidence, and apply to the First-tier Tribunal (Property Chamber) or respond to any court paperwork if possession is sought.
Where do I go to make a formal challenge?
You can apply to the First-tier Tribunal (Property Chamber) to decide on the fairness or lawfulness of a rent increase, or respond to court proceedings if the landlord pursues possession.

How-To

  1. Read the written notice carefully and note the date the proposed rent increase would start.
  2. Check your tenancy type and payment period to confirm whether the landlord has given appropriate notice time.
  3. Gather evidence: copies of the notice, your tenancy agreement, receipts, and any messages about the increase.
  4. Contact the landlord or agent to ask for clarification or negotiate a mutual agreement in writing.
  5. If you agree to a change, get the new amount and start date in writing and keep a copy before paying the new rent.
  6. If you cannot agree, apply to the First-tier Tribunal (Property Chamber) or seek advice promptly about responding to any court claim; follow tribunal instructions and deadlines.

Key Takeaways

  • Always get a rent increase in writing and check the start date carefully.
  • Save evidence of payments, notices and conversations to support any challenge.
  • You can ask the First-tier Tribunal (Property Chamber) to decide if a rise is unreasonable.
