Some 96 people were intercepted in the English Channel on Friday – a day after a record 202 migrants made the trip.
The previous daily record for migrant crossings was July 13, when 180 have landed successfully UK.
Immigration Minister Chris Philp wants France to be stronger to stop boats at sea and redirect them to shore before they reach the Kent coast.
French authorities have stopped thousands of crossings this year, the government acknowledged, adding that more could be done.
Mr Philp said: “The number of illegal small boat crossings we are seeing from France is unacceptable.
“And migrants continue to arrive in Calais to make the crossing.
“The French must act harder.
“We need stricter enforcement measures, including interceptions at sea and the direct return of boats.
“The French heard this directly from the Minister of the Interior and we will continue to work with them until the situation changes.
“We will also continue to tackle the criminals who facilitate these crossings and send back migrants who arrive in the UK in this way. ”

In July, more than 1,000 migrants managed to enter the UK, according to an analysis by the PA news agency.
The Interior Ministry on Friday launched an attack against “militant lawyers” who it says are thwarting efforts to return migrants to France.
He referred to “vexatious” allegations that prevent the government and its attempts to deport migrants from the UK; however, it will not reveal how many migrants remained in the country.
Human rights charities called the comments “intimidating tactics.”
Minnie Rahman, head of public affairs and campaigns at the Joint Council for the Welfare of Immigrants, said: “Those who are forced to take desperate trips across the Channel do so because they just don’t have a other options and become dependent on those who are willing to exploit them. . “
