The Consumer Rights Act 2015 applies across the UK, including Edinburgh, and generally requires goods to be of satisfactory quality, fit for purpose and as described. Depending on the circumstances and how long ago you bought the item, you may be able to ask the trader for a repair, replacement, price reduction or refund. Your rights can differ for services and digital content, and the appropriate remedy depends on the individual facts. Keep your receipt and contact the trader first; Citizens Advice or Advice Direct Scotland can explain your options, while a solicitor regulated by the SRA can advise on a disputed claim.
