Rent Increase Limits in the UK: Is There a Maximum, or a Cap?
- There is no statutory cap on rent increases in England, and no fixed maximum percentage. A landlord can propose any figure.
- The Renters’ Rights Act 2025 did not introduce a rent cap — a widespread misconception. It changed the process, not the amount.
- The real limits are three: the market rent (tested at tribunal), once every 52 weeks, and two months’ notice.
- From 1 May 2026 the tribunal can confirm or reduce a proposed rent, but never raise it above the landlord’s figure.
“What is the maximum rent increase allowed?” is one of the most-searched landlord questions, and it has a counter-intuitive answer: in England, there is no statutory maximum. No percentage cap exists. What does exist is a set of limits on how and how oftenyou can raise rent, plus a practical ceiling on the amount that only bites if the tenant challenges. This page sets out each one, and clears up the most common myth — that the Renters’ Rights Act created a cap.
Is There a Legal Limit on Rent Increases in England?
No. There is no statutory percentage cap on rent increases for private assured tenancies in England. Under section 13 of the Housing Act 1988, a landlord proposes a new rent and the tenant has the right to challenge it. Nothing in that process limits the figure you can propose before you serve.
The practical limit comes from the market, not from a percentage. If the tenant refers the notice to the First-tier Tribunal, it assesses the rent at which the property “might reasonably be expected to be let in the open market” under section 14 of the Housing Act 1988. That market figure — not any cap — is the real ceiling on what stands.
It is extremely common to read that rents “can only increase once per year and only in line with the market rate” and to conclude the Act capped rents. It did not. The Renters’ Rights Act 2025 standardised the process: Section 13 becomes the only route, increases are limited to once a year, the notice period is two months, and the tribunal can no longer raise rent above the proposed figure. The amountis still tested against the open market. “In line with the market rate” is not a cap — it is the same market rent test that has applied since 1988.
Limit 1: The Market Rent
The amount is bounded by the open market. Propose a figure your local comparables support and, if challenged, the tribunal confirms it. Propose a figure above the comparable range and the tribunal reduces it to market. Your mortgage rate, service charges, and insurance premiums are irrelevant to that assessment — the tribunal looks at what a willing tenant would pay for your specific property in its current condition.
For how that test works in practice, with the evidence that holds a figure and a worked example, see how much you can increase rent.
Limit 2: Once Every 52 Weeks
You can increase the rent on the same tenancy only once in any 52-week period through the Section 13 process. GOV.UK guidance states that landlords can increase rents once per year to the market rate (GOV.UK: Rent increases). A second increase inside 52 weeks is not legally possible through Section 13, whatever the tenancy agreement says. The timing has an edge case for long-running tenancies — see the 53-week rule.
Limit 3: Two Months’ Notice
From 1 May 2026 a Section 13 notice must give the tenant at least two months’ noticebefore the new rent takes effect, up from one month previously. This is both a limit on you and the tenant’s window to decide whether to challenge the figure at tribunal.
The Tribunal Can No Longer Raise the Rent
For increases taking effect on or after 1 May 2026, section 14ZB of the Housing Act 1988 (inserted by section 7 of the Renters’ Rights Act 2025) requires the tribunal to set the open-market rent if lower than the proposed rent, and otherwise the proposed rent. GOV.UK summarises it as tenants never paying more than the landlord asked for. The landlord’s proposed figure is now the effective maximum for that round — the tribunal can only confirm or cut it.
Rent-Review Clauses No Longer Work
If your tenancy agreement contains a rent-review clause or an escalator formula, note that from 1 May 2026 the Section 13 notice is the only lawful way to raise rent on an assured tenancy. A pre-agreed formula in the agreement cannot be used to bypass the statutory process or to exceed the market rent test.
What About Wales and Scotland?
The picture differs by nation. England has no statutory percentage cap. Scotland and Wales run their own frameworks for some tenancies and have used temporary measures at various points. This guide is England-only. If your property is elsewhere, check the rules that apply in that nation, which are set separately from the Housing Act 1988.

Frequently Asked Questions
What is the maximum rent increase allowed in the UK?
In England there is no maximum percentage set by statute. A landlord can propose any figure on a Section 13 notice. The practical ceiling is the market rent: if the tenant challenges, the First-tier Tribunal sets the open-market rent under section 14 of the Housing Act 1988, and from 1 May 2026 it cannot set a figure higher than the landlord proposed. So the real maximum is whatever your local comparable evidence supports.
Did the Renters’ Rights Act 2025 introduce a rent cap?
No. This is a common misconception. The Renters' Rights Act 2025 did not introduce a percentage cap on rent increases in England. It standardised the process — Section 13 becomes the only route, increases are limited to once a year, the notice period is two months, and the tribunal can no longer raise the rent above the landlord's proposed figure. The amount is still tested against the open market, not capped at a fixed percentage.
How often can rent be increased in England?
Once every 52 weeks on a periodic assured tenancy, using a valid Section 13 notice. You cannot increase more frequently than this, regardless of what the tenancy agreement says. From 1 May 2026 each increase needs at least two months' notice.
Is there a rent cap in Wales or Scotland?
The position differs by nation. England has no statutory percentage cap. Scotland and Wales operate their own frameworks for some tenancies and have used temporary measures. This guide covers England only. If your property is in Wales or Scotland, check the rules for that nation, which are set separately.
Can a tenancy agreement limit how much the rent can rise?
From 1 May 2026, rent-review clauses in assured tenancy agreements no longer take effect — the Section 13 notice is the only lawful mechanism to increase rent. A pre-agreed escalator or formula in the agreement cannot override the statutory process or the market rent test.
