What procedure must I follow to dispose of uncollected goods – when can we throw then out?
In England and Wales the situation is covered by the Torts (Interference with Goods) Act 1977. Repairers may detain goods until charges are met, and sell the goods if the customer does not return (a period of not less than 3 months springs to mind). It is advisable to retain the right to do this by stating it on the contract, or on a prominent notice. You should also take reasonable steps to trace the owner before selling.
