Common mistakes include contacting only the manufacturer, losing proof of purchase, and waiting too long to report the fault to the retailer. Under the Consumer Rights Act 2015, you may have a short-term right to reject faulty goods within 30 days, but after that a repair or replacement will usually be considered first. Do not assume you are entitled to a full refund if the fault resulted from misuse or if you have accepted a repair; the outcome can depend on the circumstances and the goods’ age. Keep records of the fault and your conversations, and seek advice from Citizens Advice or a solicitor regulated by the SRA if the retailer refuses to help.
