Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers

“As disclosed above, there has been additional investment in the group made by shareholders after the reporting date to support the group's short-term working capital position. Assurances have been obtained by the group from its shareholders, BGF Investments LP and BGF UK Enterprise Fund 3 LP, that they remain supportive of the group and will consider providing additional investment if required in the next 12 months to allow the group to continue as a going concern but do not currently consider that this is required based on the latest forecasts. They have also confirmed that they have no intention to seek early repayment of any long-term amounts due or seeking repayment of any short-term funding provided to the detriment of other creditors. As with any group or company placing reliance on shareholders for financial support, the directors acknowledge that there can be no certainty that this will continue although, at the date of approval of these financial statements, they have no reason to believe that this support will not continue for a period of at least 12 months from the date of approval of the financial statements. On that basis, and along with recent results and forecasts, the directors have a reasonable expectation that it is appropriate to adopt the going concern basis in the preparation of the financial statements and are confident that the group and company will have sufficient funds to continue to meet their liabilities as they fall due for at least 12 months from the date of approval of the financial statements.”
