John Carr, from the England and Wales Cricket Board, arrived on Friday to visit all the venues for the matches on a truncated tour.
"John Carr and another official travelled to Galle on Saturday, they will visit Kandy and Colombo venues later in the week", a top Sri Lanka Cricket (SLC) official said.
England will play five one-day internationals in the first leg of the visit from Oct 1 in the central town of Dambulla and in Colombo before returning home. They will come back in early December for the three-match Test series.
The English officials said they would closely assess the security situation in Sri Lanka as the island's long drawn out separatist armed conflict with the Tamil Tiger rebels continues.
More than 5,000 people have been killed in the new cycle of violence which began at the end of 2005.
The Bangladesh cricket team concluded a three-match Test and one day international series early this week free of any incident despite initial security fears.
The South African team abandoned a triangular series with hosts and India in Colombo and returned home in August last year due to a bomb explosion blamed on the Tamil Tiger rebels not very far from the team hotel.
