"A notice that does not comply with the prescribed form is of no effect. The landlord must start the process again from scratch."
— First-tier Tribunal (Property Chamber) guidance, 2026
If your Form 4A is invalid, the rent stays at the old level. You lose every month of the increased rent while you wait to re-serve the notice.
On an average UK rent of £1,377/month, a £100/month increase delayed by 3 months costs you £300 in lost rent — your first notice on RentNotice is free when you register.
Tenants also have the right to refer your notice to the First-tier Tribunal if they believe the proposed rent is above market rate. A correctly completed notice makes that process cleaner for you too.
