Following a lengthy investigation, the UK privacy watchdog concluded the Internet giant was not fully complying with the UK Data Protection Act.
This comes after other privacy watchdogs throughout Europe, in countries including Germany and Italy, have also reached the same conclusion.
The initial motivation for the ICO investigation actually came from the French data protection organisation Commission Nationale de l'Informatique et des Libertes (CNIL) launching an investigation into Google's privacy policies.
The CNIL investigation stemmed from Google unifying its 70 separate privacy policies into one cohesive document for digital marketing purposes in order to help it to generate more user specific targeted advertising.
In a statement, the Information Commissioners Office, said: "We believe that the updated policy does not provide sufficient information to enable UK users of Google's services to understand how their data will be used across all of the company's products.
"We have engaged fully with the DPAs involved throughout this process, and we'll continue to do so going forward."
