Understanding Rent Disputes

Rent claims can go both ways - landlords claiming arrears or tenants claiming overpayments. Both follow similar processes in small claims.

Common scenarios: - Tenant owes rent - landlord pursuing - Tenant overpaid after tenancy ended - claiming refund - Rent reduction agreement disputes - Service charge disagreements

Note for landlords: You can claim rent through small claims while also pursuing possession through different proceedings. The two are separate.

Evidence You Need

Essential evidence: - Tenancy agreement showing rent amount and due dates - Rent payment history (bank statements) - Notice documents (if applicable) - Communication records about the dispute

For landlords claiming arrears: - Schedule of rent due vs rent paid - Any correspondence about missed payments - Evidence of attempts to resolve

For tenants claiming overpayment: - Proof of payments made - Evidence of correct rent amount - Correspondence requesting refund

What You Can Claim

Typical claim value: £100 - £10,000

Landlords can claim: - Unpaid rent - Interest (contractual if in agreement, otherwise 8% court interest) - Late payment fees only if specified in agreement

Tenants can claim: - Overpaid rent - Interest from date overpayment was requested back

Service charges: Disputes about service charge reasonableness may need to go to a tribunal rather than small claims.

Common Issues and Defences

Tenant defence - "set-off": Tenants may argue rent was withheld due to landlord breaches (e.g., repairs not done). Courts can consider whether the withholding was justified.

Tenant defence - "agreement to reduce": If rent was reduced by agreement (e.g., during COVID), this affects what is owed. Get agreements in writing.

Landlord defence - "deposit covers it": Landlords may try to use the deposit for rent arrears. Deposits should only cover damage, not rent (unless specified).

Both sides - calculation errors: Carefully verify calculations. Courts will use accurate figures, not claimed ones.

Frequently Asked Questions

Yes. The rent claim (money) and possession proceedings (eviction) are separate. You can claim rent arrears in small claims while separately seeking possession through the appropriate eviction process.
