Automated (or Automatic) Telling (or Teller) Machines.

Also: 'hole-in-the-wall', 'bank machine', 'cash machine' or 'cashpoint'.

London is well served with banks, and you are rarely far away from an ATM. Be careful of standalone ATMS located in newsagents as these are likely to charge you a fee. They should have a notice indicating to if this is the case, but ask if you're unsure.

There is an ATM locator to be found at http://www.visa.com/pd/atm/main.html
