The FCO said the flights would take place “over the next few days” with the first departing from Lima on Sunday (29 March).
Domestic flights from Cusco and Arequipa to Lima will also be chartered to transfer UK nationals to London-bound flights.
The expanded repatriation operation followed an FCO-organised BA service earlier this week which flew home 172 Brits and their dependents.
All commercial internal and international transport connections in Peru are closed with thousands of foreign visitors seeking to leave.
The FCO said it was contact with British travellers with the details of the flights.
Foreign Secretary Dominic Raab said: “We continue to work around the clock to help British travellers struggling to get back to the UK and thank the Peruvian government for all their support in making this happen.”
British nationals in urgent distress and who need immediate consular assistance can call 0207 008 1500.
