8 Jun 2026Costs at a rent tribunal: when you can claim, when you might pay (Rule 13) — tenant walkthrough 2026
One of the biggest fears that stops tenants challenging a rent increase is the thought of a costs bill if they lose. The good news is that the rent tribunal almost never orders one side to pay the other's costs: each side normally bears its own. There is a narrow exception, Rule 13, for unreasonable behaviour, and it can cut both ways. This walkthrough explains how costs really work at the First-tier Tribunal, when you could ask for your costs back, when a landlord might try it on against you, and what to write if you need to make or answer a costs application. England only, Section 13 rent challenges.
