The activist has lived at the address in Hans Crescent since they granted him diplomatic asylum after the 45-year-old faced extradition to Sweden to face rape charges.
The UK stationed police officers outside the embassy 24 hours a day in a multi-million pound operation.
But in 2015 the decision was made to stop the the surveillance, after costing an estimated £11.1 million.
The Australian claims he fears being extradited from Sweden to the US after they launched a criminal investigation into the publication of confidential cables, the majority of which were provided by Chelsea Manning.
They were a great embarrassment to the US as they exposed sensitive information relating to the wars in Afghanistan and Iraq.
But in a positive step towards his situation, the United Nations (UN) ruled last year his detention was illegal and said he should be allowed to be released, the decision Julian Assange was referring to.
They added that both Britain and Sweden should pay the activist compensation.
With no firm end in sight, Mr Assange has frequently given press conferences and statements from a small balcony at the residence where he lives.
Not short of fans, an unlikely admirer has come in form of former Playboy model Pamela Anderson.
The blonde bombshell has been spotted visiting Mr Assange at the embassy several times over the past couple of months, sparking rumours the pair have struck up a close friendship.
Still active in his position as editor-in-chief, WikiLeaks dropped another bombshell when it published Vault7 in March, a cache of thousands of documents supposedly from the CIA detailing hacking and surveillance tools.
Mr Assange previously described the documents as: “Exceptional from a political, legal and forensic perspective.”
In another twist in the WikiLeaks saga, which has dragged into it fifth year, President Barack Obama commuted Ms Manning’s sentence as one of his last acts in office.
Ms Manning, the US army solider formerly known as Bradley, was convicted of espionage among other offences, and was sentenced to 35 years in prison.
This was commuted to seven by President Obama, meaning Ms Manning is due to be released on May 17.
