Thomas’s has four schools, in Battersea, Clapham, Kensington and Fulham, and while several students are believed to have been tested, no one has received a positive result for COVID-19.
A spokesman for Thomas's schools said: "Due to the increasing numbers of children and staff being absent from school due to the coronavirus situation, Thomas's London Day Schools have decided to move to remote learning from Friday 20 March.
"From this date the curriculum will be taught through online learning platforms and we have asked parents to keep their children at home and to access their lessons through this system.
"This will ensure that children have continuity of learning when they are unable to attend school,” the spokesperson said.
