New arrivals generally have the same consumer protections as other customers when buying from a UK trader, regardless of nationality, although the rules can vary across the UK and by contract. Goods should be as described, of satisfactory quality and fit for purpose; depending on the circumstances, you may be able to ask the seller for a repair, replacement or refund. Online, phone and mail-order purchases usually have a 14-day cancellation period, subject to exceptions. Keep receipts and messages, complain to the trader first, and contact Citizens Advice or the relevant official consumer service if you need further guidance.
