You can find GOV.UK guidance on consumer rights, including faulty goods, services and digital content, by searching GOV.UK for “Consumer Rights Act 2015”. The guidance explains the remedies that may be available, such as repair, replacement, repeat performance or a price reduction, depending on the circumstances. You can also check Citizens Advice for practical steps on raising a complaint with a trader. If the dispute is complex or involves a significant amount of money, consider getting advice from a solicitor regulated by the SRA.
