The blazes took place at across four days at Starmer’s north London home, a second property and a vehicle linked to him.
The Met Police said they are keeping an "open mind" as to whether the three incidents were linked.

The door to the four-bedroom property was damaged but nobody was injured. Counter terrorism police earlier this evening said they were investigating the blaze.
It has now been revealed that two other fires broke out at locations connected to Starmer in the days prior.
One was at the entrance of another property linked to Starmer in North London on Sunday, with one person being assisted to safety by fire crews wearing breathing apparatus.
The other blaze involved Starmer's old car outside his North London home.

A Met spokesman said: “The investigation team are also considering two other incidents — a vehicle fire in NW5 on May 8 and a fire at the entrance of a property in N7 on May 11 — and are investigating whether they may be linked to the fire in NW5 on May 12.
“At this early stage of the investigation, officers are working to establish the circumstances of all three fires and are keeping an open mind as to whether there is any connection. All are being treated as suspicious at this time, and inquiries remain ongoing.”
Following the blaze at Starmer's property, a Downing Street spokesman said: “The Prime Minister thanks the emergency services for their work.
“The incident is subject to a live investigation and we won’t be commenting further.”

Zosia Lewis, Daniel Formentin and Leonorah Ward leave Westminster Magistrates' CourtPAStarmer now lives at No10 and is letting out the property, which is believed to be worth around £2million.
It has been targeted repeatedly by protesters, including pro-Palestinian activists who have staged demonstrations outside.
Last year, Leonorah Ward, 21, from Leeds, Zosia Lewis, 23, from Newcastle-upon-Tyne, and Daniel Formentin, 24, from Leeds, were found guilty of public order offences after they hung a banner outside a property which read “Starmer stop the killing”.
The group were also found guilty of breaching court bail.
The PM's wife, Victoria, told Westminster magistrates’ court that she felt “a bit sick” and “uncomfortable” during the protest.
