RRA 2025 — Rent increase rules rules for landlords 2026

What you must do

Under the Renters' Rights Act 2025 rent can only be increased once every 12 months, using the statutory Section 13 procedure and the prescribed form (Form 4A), giving at least two months' notice. Rent-increase clauses that try to bypass this are unenforceable, and tenants can challenge an increase at the First-tier Tribunal. CertSafe tracks the earliest date on which you could next lawfully raise the rent, based on the tenancy start or your last increase. Always use the current prescribed form.

This is a legal obligation for private landlords in England. Keeping dated records is the simplest way to prove you have met it if a tenant, council or lender ever asks.

How often / when

Every 1 year.

CertSafe works out the exact next-due date for your property automatically once you enter when it was last done, and reminds you at 60, 30, 14, 7 and 1 days before — plus if anything slips overdue.

The penalty for getting it wrong

Invalid rent increase; tenant can challenge at tribunal.

Penalties are set by legislation and enforced by local authorities or the courts. They can also complicate possession, mortgage and insurance matters, which is why lenders increasingly ask to see a compliance record.

Your quick checklist

1. Find the date this was last done (or arrange it now if it hasn't been).

2. Keep the certificate or record somewhere safe and give any required copy to your tenant.

3. Diarise the next deadline — or let CertSafe track it and remind you.
