The quintet of Alex Corbisiero, Dylan Hartley, Courtney Lawes, Calum Clark and Tom Wood are among the forwards while Lee Dickson, Stephen Myler, Luther Burrell and Ben Foden complete the Gardens representation in the backs.
The group, who are undergoing a strength and conditioning assessment and rugby training, are in camp until Wednesday and head coach Stuart Lancaster says it is a good chance to see where everyone is at ahead of the 2014/15 season.
"This camp will give us a chance to get the wider squad together and an opportunity to review the New Zealand tour,” he commented.
"It will be an important few days for us in terms of complementing the work that the clubs have been doing in pre-season with their strength and conditioning but also from a rugby point of view. The next time we meet will be two weeks before we play New Zealand in the QBE Internationals so this time together is vital.
"In collaboration with Premiership Rugby we have been given the flexibility to announce the England Senior and Saxons squads in October, much closer to our four international matches in November. We appreciate their support of our proposal which enables time to assess the first part of the club season and therefore select players who are in form leading into an important series for us.
“It also allows an opportunity for players not involved in the training camp this week to put down a marker in terms of their performances ahead of the squad announcement."
A senior squad consisting of 33 players and a 32-man Saxons squad will be announced in October.
