Many banks noted that an increasingly large proportion of customers choose to bank from the comfort of their own homes.
Seeing them use their smartphones or computers to manage their money, rather than travelling to a branch and waiting in a queue.
The banking groups include NatWest, Lloyds, Halifax, Bank of Scotland and RBS.
This will mean that London will see many high street banks close down in the coming months.
NatWest, Lloyds and Halifax all have a number of branches in the capital that will be closing their doors for good.
