Tribunals reject rent-increase applications without hard evidence, say Propertymark and Letting Agent Today

Two recent publications highlight a sharp rise in rent tribunal evidence requirements for letting agents managing assured shorthold tenancies. Propertymark published guidance on 18 October 2026 analysing four First-tier Tribunal decisions on rent review clauses, while Letting Agent Today reported on 15 October 2026 that tribunals are rejecting applications from agents who do not supply sufficient comparable data, property detail, or condition evidence. Both sources point to higher scrutiny under Schedule 2 of the Housing Act 1988, and agents may wish to review their processes before submitting future applications. Readers should verify all procedural detail against the cited sources before taking action; WatchdogHQ is an information and awareness service, not legal advice and not a solicitor.

What the tribunals are saying: four decisions analysed by Propertymark

Propertymark's guidance, published 18 October 2026, reviews four First-tier Tribunal decisions that clarify how tribunals assess whether landlords have properly followed contractual notice requirements and whether proposed rent increases are market-reasonable under Schedule 2 of the Housing Act 1988. Agents may wish to review the Propertymark guidance to confirm their rent review notice templates align with the contractual and statutory requirements identified by the tribunal decisions. One suggested approach is to verify with your compliance team that staff serving rent increase notices understand the distinction between contractual review clauses and statutory Section 13 notices under Schedule 2 of the Housing Act 1988. The full guidance is available at Propertymark.co.uk.

Tribunals are rejecting applications without hard evidence

Letting Agent Today reported on 15 October 2026 that the First-tier Tribunal (Property Chamber) is rejecting rent-increase applications from landlords and agents who fail to provide comparable evidence, accurate property descriptions, and realistic condition assessments. Agents submitting tribunal applications under Schedule 2 of the Housing Act 1988 now face higher evidential standards for rent determinations. One suggested approach is to review your current tribunal-application templates to confirm they include fields for comparable evidence—recent lettings of similar properties in the same area—as well as accurate property descriptions and a realistic condition assessment. Agents may also wish to note that vague or unsupported applications are being dismissed; each submission should include specific local comparables and photographs or survey evidence of condition where relevant.

Propertymark calls for clearer guidance as tribunal cases surge

Propertymark called for clearer guidance on rent tribunal evidence and process under the Renters' Rights Act 2025, following a surge in tribunal cases reported on 10 September 2026. The government announced that HMRC's Valuation Office will become responsible for making determinations in rent tribunal cases. Agents may wish to note that HMRC's Valuation Office will handle tribunal determinations and check for published guidance on their process and evidence standards. Multiple sources—including The Negotiator and Property Industry Eye, both reporting on 11 September 2026—confirm that First-tier Tribunal (Property Chamber) cases have risen since the Renters' Rights Act 2025 took effect on 1 May 2026, as tenants challenge rent increases and possession grounds.

What agents may wish to check in their comparables process

One suggested approach is to check your comparables process: confirm that when supporting a landlord rent proposal, your evidence includes recent lettings of similar properties in the same locality, as tribunals rely on market data to assess reasonableness. Agents may wish to verify with their compliance team that staff preparing tribunal applications under Schedule 2 of the Housing Act 1988 are familiar with the evidential requirements reported by the tribunal. Agents often choose to confirm that case files for pending or future applications contain sufficient comparable rental data to support the proposed rent level. One suggested approach is to consider flagging to landlords that tribunals may reduce proposed increases where the evidence does not support the new rent as market-reasonable, even if the contractual process was followed correctly.

Longer timescales and increased tribunal capacity concerns

Savills' head of residential research Lucian Cook warned on 11 September 2026 that tribunal capacity may struggle to meet increased demand, which could delay dispute resolution for landlords and agents. Agents may wish to consider building longer timescales into possession and rent-review processes to account for potential tribunal delays reported by Savills. One suggested approach is to confirm that landlords are briefed on the increased likelihood of tribunal referrals and the evidence standards required under the new possession grounds.

Verify all detail against the sources before acting

Readers should verify all procedural and evidential requirements against the Propertymark guidance (18 October 2026), the Letting Agent Today article (15 October 2026), and Schedule 2 of the Housing Act 1988 before taking action.
