“The directors, having considered the group's current year performance and the group forecasts for the period to December 2025, have a reasonable expectation that the company has adequate resources to continue in operational existence for a period of 12 months from the date of approval of these financial statements and therefore have prepared the financial statements on a going concern basis.”

Significant events
- “At the start of the year in America we had two incidents which unfortunately led to two fatalities. These incidents lead to a change in our cleaning policies and process. This also led to a temporary loss of revenue while operations stopped and new ways of working put in place. The change in practice also meant we incurred additional cost in this type of close entry cleaning.”
