CT600, consolidated accounts and IXBRL

We have a client which is the holding company of a group required to produce consolidated accounts, as such its accounts do not show its P&L, just the consolidated P&L. In terms of sending accounts to HMRC would you send the Consolidated accounts and the individual companies P&L, or would you just send a set of accounts for the entity with all the notes, but one that has never been filed at Companies house?
