In their statement accompanying the results, the directors said: “The results for 2014 reﬂect the company’s strategy for continued growth in turnover, whilst reducing the business risk placed on dependency in any one industry sector or geographic area.
“Closing the year, the pre-tax profit for 2014 was £5.6m with an order book reﬂecting a positive future outlook.
“The trading environment though is expected to remain competitive, especially with the current reduction in oil prices. Increased short term competition is expected, however risk is reduced by the company’s involvement in Aerospace, Medical and Energy industries.
“Through 2015, the company is planning to increase its investment in new plant and machinery to support its strategic customers and business sectors across the world.”
