Why letting agents can't afford to get this wrong
The Renters' Rights Act tips the balance. A flawed Section 13 notice no longer just delays the increase – it hands your tenant the upper hand.
Challenges are effectively risk-free for tenants
Under the Renters' Rights Act, any tenant can refer a Section 13 notice to the First-tier Tribunal for just £47. The Tribunal cannot raise rent above your proposal – so challenging costs tenants almost nothing and can only help them. Without solid evidence, you have no defence.
Notices fail on small technicalities
The wrong effective date, incorrect landlord details, or a superseded form version – the Tribunal can invalidate a Section 13 notice on any of these grounds. When it fails, the rent increase fails. You lose months of income and start the clock again.
Your strongest evidence isn't on Rightmove
Comparable achieved lets are the gold standard evidence the Tribunal looks for – but they live inside agency CRMs, not on public portals. Pulling, formatting, and presenting them manually takes hours and requires judgement that's easy to get wrong under pressure.
From tenancy to tribunal-ready in four steps
Rentfort guides you through the entire process. No compliance training required.
Add the property and tenancy
Enter the property address and current rent. Rentfort validates the tenancy details and checks that the proposed increase is correctly timed for the tenancy type.
Pull in comparable lets
Rentfort sources 3–6 comparable achieved lets from your locality. You review and approve every comparable – nothing is submitted without your sign-off.
Generate a perfect Form 4A
Every date is calculated correctly: the proposed effective date, the minimum notice period, the challenge window. No manual arithmetic, no risk of error.
