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.

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

From the date you submitted your application to the tribunal — not from the start of your tenancy. There is no backdating to when the tenancy began.

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

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. This right was introduced by the Renters’ Rights Act 2025. Most tenants don’t know it exists.

Who qualifies

Any new private assured tenant in England. There is no minimum rent threshold and no requirement that you objected to the rent at the time 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. The tribunal uses open-market comparables — what similar properties in your area are actually letting for. Search Rightmove and Zoopla for properties nearby with similar size, type, and condition. Look at recently achieved rents, not just current asking prices. If comparable properties are consistently renting for less than you’re paying, you likely have a case worth pursuing.

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

Use Rents 1 — the application to the First-tier Tribunal (Property Chamber). Submitting the application is free, and there is then a £47 payment to process it. (Most content online refers to “Form 6” — that was the old name. The current form is Rents 1.)

What the tribunal can do

The tribunal determines what the open-market rent should be. It can only reduce your rent — never 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 you submitted your application — not the start of your tenancy. There is no backdating.

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.
