Submission of Accounts to Companies House

Hello,

I hope someone will be able to answer my question.

I am an ACCA affiliate carrying out some sub contract work predominantly internal management accounts and book keeping for very small organisations. What I wanted to know was firstly:

1) Doe it require a qualified accountant to prepare and file accounts to companies House

or

2) Can any unqualified accountant (or individual) prepare & submit these account?

I am new into sub-contracting - so am not sure of who can do the above?

Many thanks.
