How long do I have to challenge my starting rent?

You must apply to the First-tier Tribunal within 6 months of your tenancy start date. There are no extensions. After 6 months this specific right expires.

Can the tribunal raise my rent if I challenge my starting rent?

No. The tribunal can only reduce your starting rent, never raise it. If it determines your rent is at or below market rate, your agreed rent simply continues.

What if I've been in my tenancy for more than 6 months?

The initial rent challenge right has expired. You cannot use this route after 6 months. If your landlord subsequently serves a rent increase notice, you can challenge that separately through the standard Section 13 process.

Can my landlord evict me for challenging my starting rent?

No. Section 21 no-fault evictions are abolished by the Renters' Rights Act 2025. Your landlord cannot end your tenancy in retaliation for making an application to the tribunal.

Can I Challenge the Rent I Agreed to When I Moved In?

Q: When does the new rent take effect if the tribunal reduces it?

From the date the tribunal directs, which cannot be earlier than the date you submitted your application. There is no backdating to when the tenancy began.

Yes, if you are a new private tenant in England, you have a right to challenge the rent you agreed to when you moved in. The Renters’ Rights Act 2025 introduced this right and it has been in force since 1 May 2026. Most tenants don’t know it exists.

Who qualifies

Private assured tenants in England can qualify if they apply within 6 months of the tenancy start. The commencement rules also preserve this route for an eligible tenancy that began before 1 May 2026 if its 6-month application window was still open on that date. There is no requirement that you objected to the rent when you signed.

The deadline

You must apply to the First-tier Tribunal within 6 months of your tenancy start date. There are no exceptions and no extensions. If you have concerns about your rent, act well before that deadline.

Is your rent above market rate?

Before applying, do a rough check using similar nearby properties. Rightmove and Zoopla listings can help show the market, but they usually show asking figures rather than proof of the final agreed rent. Actual comparable tenancy agreements or confirmation from an agent are stronger evidence. If the evidence consistently points below what you pay, the application may be worth exploring.

You don’t need formal valuations to apply, but gathering a handful of solid comparables before you submit will strengthen your position. For detail on what the tribunal looks at and how to prepare evidence, see our guide on the tribunal process.

How to apply

Apply for an open market rent determination through the online service or on paper using form MR1. The application normally costs £47, although exemptions and help with fees may apply. Ask us for free help if you are unsure how to begin.

What the tribunal can do

The tribunal determines what the open-market rent should be. It can only reduce your rent. It cannot raise it. If it finds your agreed rent is at or below market rate, the application is dismissed and your rent continues unchanged.

If it determines your rent is above market, it sets the lower figure. That new rent takes effect from the date the tribunal directs, which cannot be earlier than the date you submitted your application. There is no backdating to the start of the tenancy.

Your tenancy is protected

Section 21 no-fault evictions are abolished. Your landlord cannot end your tenancy simply because you applied to the tribunal.

Why this right exists

The Renters’ Rights Act 2025 also bans landlords from accepting offers above their advertised asking rent. Doing so carries a civil penalty of up to £7,000. The initial rent challenge right is the tenant-side counterpart: a route to tribunal if you believe the rent you agreed to was set above the market, whether through competitive pressure or otherwise.
