The Home Office confirmed they were picked up about 12pm on Saturday in the St Margaret’s Bay area, off Kent.
The group presented themselves as Afghan and Iranian nationals.
They have been medically assessed and transferred to immigration officials for interview.
A Home Office spokesperson said: “Crossing the Channel in a small boat is a huge risk. The criminal gangs who perpetuate this are ruthless and do not care about loss of life.
“We are working closely at all levels with the French authorities to tackle this dangerous and illegal activity. In addition, Border Force cutters are patrolling the Channel and we have deployed equipment to detect migrant activity.
“Last month, the Home Secretary and her French counterpart agreed to intensify joint action to tackle small boat crossings in the Channel. This includes drawing up an enhanced action plan to deploy more resources along the French coast to intercept and stop crossings.”
