What happens if I do not pay the increased rent while I challenge it?

You do not have to pay the increase while your tribunal application is pending. Continue paying the old rent, keep a separate record, and the tribunal will set the correct amount once it decides.

Can my landlord evict me for challenging a rent increase?

No. Retaliatory eviction is illegal. A landlord cannot serve notice simply because you disputed a rent rise at tribunal.

What counts as 'open-market rent' for a tribunal?

The rent a similar unfurnished property in your area would achieve if advertised today. Tribunal panels look at current Rightmove, Zoopla, and local agent data, not your landlord's opinion or what they paid for the building.

If I'm in an old tenancy (before 1 May 2026), do these rules apply?

If your tenancy continues after 1 May 2026, it converts to an assured periodic tenancy and the new rules apply from that date, including the once-per-year cap and market-rate limit.

Can a rent increase take effect before 2 months are up if I agree?

No. The 2-month notice period is a legal minimum and cannot be shortened, even with tenant consent.

Can a landlord increase rent mid-tenancy in the UK?

By Andrew Dunne, founder of Claro · Updated 16 June 2026 · Checked against official gov.uk guidance

From 1 May 2026, a landlord can increase rent only once per year on an assured periodic tenancy, and must use a formal Section 13 notice giving at least 2 months' notice. The new rent must not exceed the open-market rate for a similar property. No increase is allowed in the first year of a tenancy.

If you believe the increase is above market value, you can challenge it at the First-tier Tribunal without a lawyer, and you do not have to pay the higher amount while that challenge is ongoing. If the tribunal agrees the increase is too high, it will reduce the rent to market level.

The short version:

Landlords can only raise rent once per year, not mid-tenancy at will
A Section 13 notice (Form 4A) with at least 2 months' notice is legally required
The new rent must not exceed open-market rate; you can challenge it at tribunal if it does
No increase is permitted in the first year of a tenancy
You have the right to dispute the increase before paying the higher amount

The basic rule: once per year, not mid-tenancy

From 1 May 2026, the assured periodic tenancy allows only one rent increase per 12-month period. This is a legal cap, not a suggestion. A second notice in the same year is void and you owe nothing extra.

Before 1 May 2026, older assured shorthold tenancies had similar protections, but the rules are now uniform across the private rented sector.

How a lawful rent increase must be served

Your landlord must use Form 4A and serve it with at least 2 months' written notice. A text, email without the proper form, or short notice is invalid.

The notice must state the new rent amount and the date it takes effect. Vague or incomplete notices have no legal force. If you do not receive a valid Section 13 notice, the rent cannot legally increase.

What rent level is allowed and how to challenge it

The new rent must not exceed the open-market rate: what a landlord could charge if the property were newly advertised today for a comparable unfurnished property in the same area.

If you believe the proposed rent exceeds market value, apply to the First-tier Tribunal within the period stated on your Section 13 notice. You do not have to pay the higher amount while the challenge is pending. The tribunal compares actual lettings data from Rightmove, Zoopla, and local agents, and can reduce the rent if the increase is excessive. Tenants win these cases regularly and do not need a lawyer.

The first-year freeze

In the first 12 months of a new tenancy, no rent increase is permitted under any circumstances. This is an absolute bar.

Even a rent review clause signed before 1 May 2026 is void if the increase would take effect after that date.

What the ranking pages omit: how to actually challenge the increase

Most websites repeat the rule ("once per year, market rate") without explaining *how* to push back. When you receive a Section 13 notice, you can submit evidence of comparable market rents to the tribunal. The tribunal does not rubber-stamp the landlord's figure. It compares actual lettings data (Rightmove, Zoopla, local agents' opinions) to the proposed rent and can reduce it if the increase is excessive. Tenants win these cases regularly.

The guide's rent-increase challenge template walks you through gathering comparables, framing your tribunal application, and presenting your case clearly.

When to get professional help

You can challenge a rent increase yourself at the First-tier Tribunal; the process is designed for lay people. Get help if the hearing feels overwhelming, if your landlord is using complex comparables data, or if the case involves legal points beyond the rent amount. Free advice is available from Shelter and Citizens Advice. You do not need help simply because the amount is large.
