The home side got off to the best possible start in the five-Test series, beating the tourists by 14 runs in a thrilling encounter at Nottingham's Trent Bridge yesterday.
National selector Geoff Miller said in an England and Wales Cricket Board (ECB) statement that picking the same squad would "provide options" for skipper Alastair Cook and coach Andy Flower.
Fast bowler Steven Finn struggled at Trent Bridge and even though the second Test, which starts on Thursday, is at the Middlesex seamer's Lord's home ground, consideration will be given as to whether the paceman should be replaced by either Tim Bresnan or Graham Onions.
"It was a fantastic start to the Investec Test series, with both sides showing a huge amount of skill and determination," said Miller as he reflected on a dramatic match at Trent Bridge.
"I would like to congratulate England on showing a great deal of composure to win by 14 runs." The former England off-spinner added: "I have no doubt that the rest of the series will be equally compelling.
"We have selected the same squad for the Lord's Test, because this continues to provide options for Alastair Cook and Andy Flower." England squad for second Ashes Test: Alastair Cook (capt), Joe Root, Jonathan Trott, Kevin Pietersen, Ian Bell, Jonny Bairstow, Matt Prior (wkt), Tim Bresnan, Stuart Broad, Graeme Swann, James Anderson, Graham Onions, Steven Finn.
