Under the Consumer Rights Act 2015, goods should be of satisfactory quality, fit for purpose and as described. If they are faulty, you generally have 30 days to reject them and ask the seller for a full refund, although exceptions can apply. After 30 days, you will usually need to accept a repair or replacement first; if that fails or is not provided within a reasonable time, a price reduction or final refund may be available. Keep your receipt and contact the retailer, not just the manufacturer; Citizens Advice can explain your options if there is a dispute.
