Feature
File your rent increase notice with the tenancy pack

A clean trail matters if a tenant challenges the figure. Keep the notice, proof of service, and local comps together before you send anything.
Open document hubWhat is a Section 13 rent increase notice?
Section 13 is the main statutory route for increasing rent on a periodic tenancy. You propose a new rent on the current prescribed form. Then the new figure starts on the stated date, unless the tenant challenges it first.
Also, rent review clauses no longer give you a free pass after the Renters Rights Act changes. Therefore, the notice process is now the default path for most landlords.

Form 4A rules and the once a year limit
Under the Renters Rights Act, give at least two months written notice. Also, increase rent only once every 12 months. Use the live GOV.UK form on the day you serve.

The big shift is risk. The tribunal cannot set rent higher than you asked for. It also will not backdate a win for you. So an aggressive ask now has downside, not upside.

How tenants challenge rent at the First-tier Tribunal
A tenant can refer your notice to the First-tier Tribunal before the increase date. The tribunal then decides open market rent for that property. Your mortgage rate and target yield do not decide the outcome.
Therefore, bring local comps. Same street and same postcode beat national averages every time.

Anchor the figure to recent local lettings. Meanwhile, keep photos of condition and a short note on why the rent matches the market. Guesswork invites a challenge.
Use local comps, not guesswork
Start with nearby achieved rents. Then sense-check the uplift against churn risk. A sticky tenant on a fair uplift often beats a void after a dispute.

Keep Renters Rights Act paperwork tidy while you review rent

Many landlords are still sorting the renters rights act information sheet 2026 trail. Keep that file and your Section 13 notice in the same tenancy pack.

First, confirm the tenancy is periodic and due for review. Next, gather comps and set a fair figure. Then complete the form, serve it, and store proof of service.
Finally, update payment reminders for the effective date. Clear written communication reduces surprise and dispute risk.

Are landlords planning more increases?
Market mood matters. If your area is soft, a smaller uplift can retain a good tenant. If comps are firm, a fair market ask is easier to defend.

Keep the tenancy agreement ready for rent reviews

Section 13 works best on a clear periodic tenancy. Generate or refresh your tenancy agreement template, then file later rent notices beside it.

Common Section 13 mistakes
Old forms. Too little notice. More than one increase in a year. Weak comps. Those four mistakes create most failed notices.
Also, do not use a huge mid-tenancy jump to force a tenant out. That approach invites challenge and churn.
