Challenging Rent Increases in Wales

Many tenants find a sudden rent increase stressful. This guide explains in plain language what tenants in Wales can do when a landlord proposes a higher rent, how to check whether the increase follows the law, and the official steps to challenge it. You will learn when a written notice is required, how to respond, what evidence to gather, and how to apply to the First-tier Tribunal (Property Chamber) if needed. Practical examples show when a Section 13 procedure applies and what timescales to expect. The aim is to help renters protect their budget and housing security while following the correct legal process.

How rent increases normally work

For most assured periodic tenancies, landlords must follow a formal process to raise rent. If your tenancy is periodic (rolling by week or month) landlords commonly use the Section 13 procedure in the Housing Act 1988 to propose a new rent. Check your tenancy agreement first to confirm whether it sets specific rules about increases and whether you have a fixed-term tenancy that prevents increases until it ends.

Official forms and where to use them

Below are the key official routes and forms tenants and landlords use when a rent increase arises. Links point to official government and legislation pages for current guidance and text.

• Section 13 notice (no universal paper form number) — used to propose a rent increase for an assured periodic tenancy; a landlord serves written notice setting out the proposed new rent and effective date (example: landlord sends a dated letter to begin a new monthly rent from the next rent period). See the statutory text and procedure on legislation and guidance pages.^[2]
• Written reply to a rent increase — there is no single form number for a tenant response; tenants should reply in writing, record the date, and keep a copy (example: tenant emails or posts a dated letter asking for justification and stating they dispute the increase).
• Application to the First-tier Tribunal (Property Chamber) — to dispute an increase where agreement cannot be reached, tenants can apply to the tribunal to determine a fair rent (example: after trying to negotiate and serving a written response, tenant uses the tribunal application route). Learn how to apply and use the tribunal service.^[3]

Practical steps to challenge an increase

Follow these practical steps as soon as you receive notice of a rent increase.

• Record dates and amounts: note when the notice arrived, the proposed start date and the exact new amount and keep all tenancy paperwork and receipts.
• Check the notice and tenancy type: confirm whether your tenancy is fixed-term or periodic and whether the landlord used the correct Section 13 process for periodic tenancies.^[2]
• Contact your landlord: ask for written reasons and evidence for the increase and try to negotiate (example: request a meeting or an explanation of market comparables).
• Respond quickly: if you dispute the increase, send a dated written reply stating you contest it and why and keep proof of postage or an email copy.
• Apply to the tribunal if needed: if you cannot agree, make an application to the First-tier Tribunal (Property Chamber) for a rent decision; the tribunal can set an appropriate rent.

Official guidance on raising rent and how to increase rent

What evidence helps a tribunal

Prepare clear, organised evidence to show whether the proposed increase is reasonable.

• Records of current and historic rent payments and receipts.
• Comparable rents for similar properties in your area (market evidence).
• Evidence of repairs or disrepair that affect the property condition and whether rent levels are justified.
• Copies of the tenancy agreement, the landlords notice and any written correspondence.

Possible tribunal outcomes

• The tribunal may set the proposed rent, reduce it, or defer the increase to a later date.
• The tribunal can consider fairness and local market levels when deciding a reasonable rent.

FAQ

How long does a landlord have to give notice of a rent increase?

There is no single fixed form period for every case, but Section 13 timetables and any notice period set in the tenancy agreement apply; check your agreement and relevant statutory guidance.^[2]

Can I refuse to pay the higher rent while I challenge it?

Disputing a rent increase does not automatically excuse payment of the current contractual rent; get advice and consider paying the undisputed amount into a separate account until the issue is resolved.

Who decides the final rent if the landlord and tenant disagree?

The First-tier Tribunal (Property Chamber) can decide an appropriate rent after reviewing evidence from both parties.^[3]

How-To

1. Check your tenancy and the notice: confirm tenancy type and save the dated notice.
2. Write to the landlord: explain you dispute the increase, request justification and keep a copy.
3. Gather evidence: receipts, photos, comparable rents and correspondence to support your case.
4. Apply to the First-tier Tribunal if negotiation fails: follow the tribunals application process and submit your evidence.^[3]
