How we did our research

We surveyed 3,501 members of the public in May 2015 about the big brands they had interacted with in the previous 12 months, whether face to face or by email, telephone, writing or social networking sites. Brands were chosen based on market share within their sectors and only the largest brands were included.

Each brand was rated on making their customers feel valued, knowledge of products and services, helpfulness of staff, resolving complaints or problems and access to customer support. Respondents were also asked to give brands an overall rating for customer service, which is where our customer service score comes from.
