Under the Consumer Rights Act 2015, goods you sell must be of satisfactory quality, fit for any particular purpose the customer made known to you, and as described. A term in your returns policy or receipt that tries to exclude or restrict those rights does not bind the customer. You can offer more than the law requires, but not less.
Fair trading law also bans misleading and aggressive practices, such as false claims about a product or a price.
