According to Abbey's 2006 banking report, up to 83 per cent of dissatisfied current account holders have seriously considered switching their provider but never do.
Nearly two-thirds (65 per cent) of consumers said the main reason they had not switched was that the process would be too much hassle and over a quarter thought that banks would give no help in switching.
Approximately half of dissatisfied respondents had decided not to switch because they thought all banks were the same and so there would be little point.
"If consumers are unhappy with their current account provider they should research other products on offer and switch to one that better suits their needs," a spokesperson for Which? said.
The spokesperson also pointed out that a May 2005 survey by the magazine found that over three quarters (76 per cent) of customers who switched current accounts found the process to be "very easy".To compare a range of current accounts, click here.
