Your Tenant Challenged the Rent Increase. What Happens Now?
- A challenge means the tenant has referred your proposed rent to the First-tier Tribunal before the effective date. The increase is paused until the tribunal decides.
- Since 1 May 2026, the tribunal can only confirm or reduceyour figure — never raise it above what you proposed (s.14ZB Housing Act 1988).
- The outcome turns on comparable market evidence. Thin evidence is the main reason a tribunal lands below the proposed rent.
- A challenge invites scrutiny of the notice itself — confirm yours is valid before the hearing, because a void notice fails regardless of the rent.
When a tenant challenges a rent increase, they are exercising a statutory right under section 14 of the Housing Act 1988 — referring the proposed rent in your Section 13 notice to an independent tribunal. It is not an accusation that you did something wrong, and since 1 May 2026 it carries far less risk for you than it once did. Here is what actually happens, and how to come out of it well.
The Increase Is Paused, Not Cancelled
To challenge the increase, the tenant must apply to the First-tier Tribunal (Property Chamber) beforethe effective date shown on the notice. Once they do, the proposed increase is paused: the old rent continues until the tribunal determines the figure, and the new rent then applies from the date the tribunal directs. The application is free for the tenant, which is why challenges are common — it costs them little to test the number.
The Tribunal Can Only Confirm or Reduce Your Figure
This is the change that matters most. The tribunal assesses the open market rent— what the property would let for on the open market on the same terms. Before 1 May 2026 it could land above the rent the landlord proposed. Since that date, section 14ZB(added by the Renters’ Rights Act 2025) caps the determination at the figure you proposed. In practice the tribunal can now only:
- confirm your proposed rent, if the market supports it; or
- reduce it to the market rent, if the market is lower than you proposed.
It cannot award you more than you asked for. So the proposed figure on your notice is now a ceiling, not a starting point — which makes pitching it accurately, and evidencing it, more important than ever.
The tribunal decides on market evidence, and the burden of showing the proposed rent is the market rent sits with you. Recent lettings of similar properties — same area, size, condition, and terms — are what move a determination. A landlord who turns up with three strong comparables and clean proof of service is in a very different position from one relying on assertion. Our Tribunal Defence Pack assembles the comparable analysis, the service evidence, and the procedural checklist into one dossier.
First, Confirm Your Own Notice Is Watertight
A challenge to the amount often becomes scrutiny of the notice. If the Section 13 notice is itself defective — wrong form, under two months’ notice, a mid-period effective date, or wrong figures — it is void, and the increase fails before market evidence is even reached. Before the hearing, run the validity self-check and review the mistakes that invalidate a notice. If you find a defect now, you may be better served reissuing — see how to reissue a Section 13 notice.
What to Prepare
- Comparable rents— three or more recent, genuinely comparable lettings, with sources.
- Proof of valid service — how and when the Form 4A was served (see how to serve a Section 13 notice).
- The rent history— current rent, last increase that took effect, and the dates behind your interval calculation.
- The notice itself— a clean copy showing the correct figures and a correctly aligned effective date.

Frequently Asked Questions
What happens when a tenant challenges a Section 13 rent increase?
The tenant refers the proposed rent to the First-tier Tribunal (Property Chamber) before the effective date on the notice. The increase is paused until the tribunal decides. The tribunal assesses the open market rent for the property and, since 1 May 2026, can only set that figure or a lower one — it cannot set a rent higher than you proposed.
Can the tribunal set the rent higher than I asked for?
No. Section 14ZB of the Housing Act 1988, introduced by the Renters' Rights Act 2025, caps the determination at the rent you proposed. Before 1 May 2026 the tribunal could set a higher figure; since that date it can only confirm your proposed rent or reduce it to the market rent if the market is lower.
What evidence does a landlord need at the rent tribunal?
Comparable rents for similar properties in the same area are the core evidence — recent lettings of comparable size, condition, and location. You should also have proof the notice was validly served, the dates, and the current rent history. Weak or absent comparables are the most common reason a tribunal sets a figure below what the landlord proposed.
Does a challenge mean my notice was wrong?
Not necessarily. A challenge is the tenant disputing the amount, which is their statutory right even for a perfectly valid notice. But a challenge often prompts scrutiny of the notice itself — so confirm yours is valid (right form, two months' notice, correctly aligned effective date, correct figures) before the hearing.
