Open market rent evidence for tribunal
Direct answer
For a rent increase tribunal challenge, tenants should gather comparable local rents, property condition evidence, photos, listing screenshots, floor area, amenities, and any defects that affect market value. The tribunal is focused on open market rent, not the landlord's costs.
Look for similar properties in the same area, with similar size, condition, furnishing, outdoor space, transport access, and tenancy terms. Save screenshots with dates because listings disappear quickly.
A flat with damp, broken heating, poor insulation, or unresolved repairs may not command the same market rent as a newly refurbished comparable. Use photographs, repair emails, and inspection records.
Prepare a simple table showing address or area, rent, bedrooms, condition notes, listing date, and why each comparable is similar or different. Avoid flooding the tribunal with irrelevant listings.
A set of screenshots is more useful when the tenant explains why each property is comparable or not. The tribunal needs to understand size, location, condition, furnishing, amenities, and timing, not just that cheaper listings exist somewhere nearby.
The Form 4A and rent increase rules pages answer whether the notice route is valid. This page is deliberately about evidence for the rent figure once the tenant is considering a tribunal challenge.
Condition evidence is strongest when it connects to market value. For example, damp in a bedroom, a broken boiler, missing appliances, poor insulation, or unusable outdoor space can help explain why a similar-looking listing is not a fair comparison. Keep the point focused on rent level, not general frustration.

Common questions

- The tribunal's main task is open market rent. Affordability may explain urgency, but comparable market evidence is usually more important for the rent figure.
- Can the tribunal set the rent higher than the landlord proposed?
- Current GOV.UK guidance frames the challenge around open market rent. Tenants should get advice before applying if there is a risk the market evidence is higher than expected.
- What is the deadline to challenge?
- The tenant normally needs to apply before the proposed new rent takes effect. Check the date on the notice immediately.
