Oliver, wife Jules and their four children were not at the 7 million pound Primrose Hill property when the break-in occurred on October 2, reported Female First.
The intruders are believed to have accessed the home via the garage and stole two electrical items from the basement.
"There was a break-in at the basement next to Jamie's main house - he also owns the basement - and two electrical items were stolen," a spokesman for Oliver said.
"Nothing was 'ransacked'. There's no indication that 'thousands of pounds-worth' of goods were taken. None of the family were in the house at the time. And all this happened almost two weeks ago now," he said.
A Metropolitan Police spokesperson said, "Police were called to an address on Friday October 2 shortly after 9pm after a member of the public reported that a door to the property was open.
"Officers attended and went inside the property and found that the premises had been burgled. Items were removed from the address.
