What you should know about the UK’s new 3-month rent rule

With the Renters’ Rights Act 2025 set to dramatically reshape England’s private rental sector starting 1 May 2026, many landlords may be growing increasingly anxious.

The legislation, which received Royal Assent in late 2025, abolishes “no-fault” evictions under Section 21, converts fixed-term assured shorthold tenancies (ASTs) to open-ended periodic ones, and introduces stricter rules on how and when rents can rise.

A key point to note is the raised threshold for mandatory possession under Ground 8 for rent arrears. Previously, landlords could seek eviction if tenants owed at least two months’ rent.

Under the new Act, this threshold increases to three months (or 13 weeks for weekly/fortnightly payments), with the notice period extended from two weeks to four weeks.

This change means landlords must tolerate longer periods of non-payment before courts are required to grant possession orders (assuming other conditions are met).

Combined with broader reforms this tips the balance further toward tenants and erodes landlords’ ability to manage cash flow risks effectively.

The 3-month arrears threshold

The Renters’ Rights Act aims to protect “good” tenants who pay rent and avoid breaches, allowing them to stay indefinitely in stable tenancies. But for landlords, the higher arrears bar raises practical worries:

  • Delayed recovery of owed rent – Landlords may now face three full months (plus notice and court time) without full payment before mandatory eviction proceedings kick in. In a high-interest-rate environment or with rising maintenance costs, this can strain finances, especially for smaller or leveraged buy-to-let investors.
  • Increased exposure to bad debt – Critics argue the change incentivises some tenants to delay payments, knowing eviction is harder and slower. While discretionary grounds (like Ground 10 for any arrears) remain available, they rely on court discretion rather than automatic entitlement.
  • Broader eviction challenges — The Act removes no-fault evictions entirely, so landlords must prove one of the limited statutory grounds for possession. Even for rent arrears, processes are lengthier, and new protections (such as potential compensation requirements in some redevelopment cases) add complexity.

The government defends the measure as part of a package preventing ‘backdoor evictions’ through aggressive rent demands or unfair practices, while expanding tenant security.

Official guidance notes the threshold increase from two to three months’ arrears aims to give tenants breathing room during temporary hardship without immediately risking homelessness.

Other rent-related changes fueling landlord unease

The “3-month rule” sits alongside sweeping restrictions on rent increases that many property owners view as equally disruptive:

  • Rent rises limited to once per year – Landlords can only propose increases via a Section 13 notice under the Housing Act 1988, and only after at least 52 weeks from the tenancy start or previous rise.
  • Two months’ minimum notice – Any proposed hike must come with at least two months’ advance warning, and tenants can challenge it at the First-tier Tribunal (FTT) if they believe it’s above market rate.
  • No more contractual rent reviews – Existing rent review clauses (including index-linked ones) become void, and new agreements cannot include them. Increases must align with open-market levels.
  • Tenant challenge window – New tenants can contest initial rent within six months, and all tenants can appeal Section 13 notices -potentially leading to FTT backlogs and delayed income.

These curbs, landlords argue, limit their ability to respond quickly to inflation, rising mortgage costs, or local market surges. Some fear opportunistic challenges could tie up legitimate increases for months.
