In London, as in the rest of the UK, your rights for a refund on faulty goods are protected under the Consumer Rights Act 2015. If the goods you purchased are faulty, you can request a full refund within 30 days of purchase. After this period, you may be entitled to a repair or replacement. To claim a refund, it's important to keep your receipt and to contact the retailer directly. If there are issues, consider checking the official gov.uk page or seeking advice from a consumer rights adviser for further assistance.
