Marks & Spencer
Marks & Spencer is one of Britain's most recognisable high street brands. It has taken its reputation into its banking arm, which is reflected in its high happiness and trust scores.
The banking segment of M&S is owned by HSBC. While M&S has good customer happiness and trust scores, it has a low transparency score - which can drag its overall scores down.
This means it sits outside the ribbon places for its credit cards and mid-table for its savings accounts.
