The Consumer Rights Act 2015 is the law helping buyers to obtain redress when their purchases 'go wrong'. It is in the interest of anyone who sells goods or services to understand the Act and the responsibilities they have under it.
Essentially, the Act states that what you sell must fit its description, be fit for its purpose and be of satisfactory quality. If not, you - as the supplier - are obliged to sort out the problem.
As a business you are required to comply with the Act. Doing so can enhance your customer relationships.
This guide explains the Act and how to deal properly with complaints made under it. Remember that while the Act generally applies to protect individual consumers, it can also apply to the sale of goods between businesses.
