This has resulted in a fluctuation in their figures with a corresponding increase in the total number of unclaimed deposits amongst the three schemes.Each of the three schemes may calculate unclaimed deposits differently, as an unclaimed deposit is not currently defined in law. Provisions within the Housing (Scotland) Bill will create a legal definition of when a tenancy deposit can be considered unclaimed, ensuring there is consistency in all three schemes figures if the Bill is approved.The tenancy deposit schemes have taken a number of active steps to reunite unclaimed deposits with former tenants and have recently shared best practises amongst each other.
