You can file your accounts (which are trivial for a micro entity) directly with Companies house, or, when you do your CT600 corporation tax return (which is the 6 or so numbers) there's a checkbox marked "also file to companies house".
You absolutely do not need an accountant.
You also get a great deal of time (extra on your first year) between year-end and when you have to submit, so there is no panic.
