Compile and submit accounts to hmrc

I have been let down by my accountant who has not submitted our year end accounts which are now overdue, as such i need to submit these as a matter of urgency.
I have the previous years accounts to hand along with the necessary reports, we did switch from one sage to another mid year but we have closing/opening reports.
I have a book keeper who does my basic accounts and vat returns etc.. but she is not comfortable with submitting final accounts as she is not qualified to that level.
Generally we just provide the reports to the accountants and and they ask for a stock valuation as thats about it.
The company has a turnover of £2.5m due to the high value of products and also has accounts in $ and € but is only a small business with myself as the only employee.
