Any belongings left behind by a tenant still belong to the tenant. If you therefore dispose of the belongings the tenant may bring a legal action against you. The first thing you should do is try to contact the tenant and request that they collect their belongings. A notice under the Torts (Interference with Goods) Act 1977 will need to be sent to the tenant explaining that you intend to sell or dispose of their belongings left at the property, providing a reasonable amount of time or them to be collected by.
