A certificate is required to be filed with Companies House that this is the case prior to the commencement of trading.

The accounts of a public company must be filed within 7 months of its accounting reference date, is not entitled to exemptions for filing accounts that apply to private companies and may not be voluntarily struck off the Register of Companies.
