RentCompare

Has your rent gone up more than it should have?

Enter your postcode and we will show you how rents for homes like yours have changed, what they cost now, and what the tribunal has decided for comparable properties nearby.

A tribunal cannot set your rent higher than your landlord has asked for, and your rent does not change while it is deciding — you carry on paying what you pay now, and any new rent starts from the decision rather than the date on the notice. The worst outcome is the rent you were already being asked for.

Both are optional. They turn percentages into pounds and let us weigh how strong a challenge would look. Neither is stored, and neither leaves this page.

If you have had a rent increase notice

Since 1 May 2026 a Section 13 notice on Form 4A is the only lawful way to raise the rent on most assured tenancies — Form 4 before that date, and Form 5A or 5 for an assured agricultural occupancy. You can ask the First-tier Tribunal to decide the rent instead. It can confirm the amount your landlord proposed, or lower it. It cannot set it higher.

This is information, not legal advice, and nothing here predicts what a tribunal would decide in your case. How these figures are produced.
