In the UK, the Charity Commission advice line explains that for charitable companies there are two sets of requirements - those of Companies House and those of the Charities Commission.
For members in practice, the Charity Commission's rules apply as far as thresholds are concerned, and this would currently preclude the member from examining the accounts of a charitable company with this level of turnover.
However, tests of audit are not completely straightforward and members are advised to refer to the Charity Commission guidelines, in particular publications CC31 and CC32.
