Large numbers of landlords and tenants caught up in deposit disputes failed to submit evidence to adjudicators on time.

The Deposit Protection Service said that last year almost 18% of landlords and 23% of tenants who agreed to dispute resolution either missed their deadline or sent in nothing.

Where landlords fail to provide evidence, DPS adjudicators automatically rule in favour of the tenant.

Failing to submit evidence at all was more common than missing deadlines, with 10% of landlords and 16% of tenants never sending in any evidence at all.

Alexandra Coghlan-Forbes, head of adjudication at the DPS, said: “Too many landlords and tenants are shooting themselves in the foot during disputes by failing to get us the evidence we need to assess their case.

“Our Alternative Dispute Resolution service ensures an impartial adjudication for both landlord and tenant, but is reliant on both parties submitting proper evidence in good time to work effectively.

“We do everything we can to make sure both parties understand what’s needed and by when, and it’s important that both landlords and tenants meet the 14-calendar day deadline.”
