Going concern
Affirmed

“The Directors and management of Stertil UK have considered in detail the micro and macro economic factors for the period of at least 12 months from the date the financial statements dated 31 December 2024 were approved. The trading forecasts which support the ongoing assessment has been prepared to 31 December 2026. The current conditions of the UK Economy due to changes implemented by the new government present their own unique risks of a general slowdown in the economy and volatile inflation. The company operates in a number of sectors and is well prepared to meet either growth or downturn depending on the performance of the UK Economy. The strategy has been to grow the service business which is continuing to expand and is well placed to offset any downturn in other sectors of the business. Cash reserves are sufficient to meet all obligations during 2025 and beyond. The business has a strong order book and good cash reserves and is part of a strong and stable group. The Director is confident with the cash flow forecasting and worst-case scenario given any economic downturn that there is no material risk that the Company is unable to meet its financial liabilities as they fall due for a period of at least 12 months from the signing of the Company's accounts. Based on these assessments the Director has prepared the financial statements on a going concern basis as prepared the financial statements on a going concern basis.”

Each % is (latest − prior) ÷ |prior| for the line item as filed.

Lines a company doesn't report are omitted. About these numbers
