- Going concern
- Affirmed
“The financial statements are prepared on a going concern basis. The directors have taken into consideration forecasts produced that take into account the impact of the current economic climate on both the company and the sectors it operates in. The conclusion of the directors is that they still have a reasonable expectation the company will continue in operational existence for the foreseeable future.”
Significant events
- “The war in the Middle East whilst it has disrupted travel it does not appear to be affecting the progress of our projects within the region.”
- “Turnover has increased significantly during the year due to growth in the Middle East work, however delayed payment terms associated with the Middle East projects, costs associated with delivering this work and a cautious approach to recognising revenue has has delivered a broadly breakeven position.”
