Just came across an excellent deal for switching current accounts.
Going through quidco http://www.quidco.com/santander-current-account/
Santander is offering customers £150 for transferring their current account to them (aslong as u pay in more than £1,000 per month. On top of this they are offering an amazing 5% interest for the first year (unheard of for a current account) and a 0% overdraft for the first 4 months.
The excellent part is that it seems to be very hassle free - they transfer all your standing orders and direct debits on your behalf and cover any charges you incur in the process. So the only thing you have to do is notify your work of the new details and voila £150 for nothing.
