Basic Rights
The law currently states that under these pieces of legislation, a consumer has the right to goods that are deemed to be of a satisfactory quality, fit for purpose and ‘as described’. Satisfactory quality implies that the goods are free from any faults or manufacturing defects, safe, resilient and long-lasting, and have a satisfactory appearance and finish.

Fit for purpose entails that the goods are fit for the specific purpose for which they were made. Examples of fit for purpose include waterproof or water resistant goods. The term ‘as described’ means that the goods on offer should accurately concur with the description applied to them. This includes descriptions such as the size of colour of the goods.

At this point it’s worth noting that when entering into a sale with an individual the only consumer right that applies in this instance is that the item is ‘as described’. You should also consider that when buying second hand goods, your basic consumer rights still apply, except the law states that it is reasonable that expectation about the durability and performance of the goods should be lowered. Consumer rights also apply to goods bought in sale (stock clearance), but if the goods are on sale because of a defect, then the consumer cannot demand a refund due to that fault at a later stage.
