Which? responds to latest CMA banking satisfaction survey

"As is becoming tradition, challenger banks lead the way when it comes to quality customer service - results also reflected in Which?'s surveys of current account customers. 

"These results should serve as a wake-up call to high street banks to up their game - and the CMA must not hesitate to take action against firms that fall short of their regulatory requirements.  

"For customers unhappy with the quality of service they're receiving, it's never been easier to switch. Most banks have agreed to use a switching service, which means it should take just seven working days to switch you over from your old account once the new account is opened."
