According to the Daily Telegraph, the squatters have vowed to occupy dozens more to force wealthy owners to "squat proof" their properties.
A spokesman for the squatters, documentary maker Mark Guard said the group only squatted legally in properties that were empty for weeks.
"We are going to target the properties if these owners don’t make sure they are squat proof," he said.
"There are some 312 properties that are lying empty in Belgravia. We are sending a message out to say, if you don’t look after your home – these guys will take it over."
