The consulting giant revamped operations following a drop in pre-tax profits during the first half of the financial year caused in part by problems with rail contracts.
But the business has bounced back with a 14.6% rise in underlying group pre-tax profit for the year to March 31 2015 on a steady turnover of £1,756.6m.
Atkins is now making an underlying 7.6% margin with a target of 8%.
In the UK operating margins were 7.1% as the consultant made an operating profit of £59.4m on a turnover of £835.6m.
The consultant currently employs 8,885 people in the UK.
Looking forward, Atkins said: “In the UK, the infrastructure markets continue to present opportunities for our broad multidisciplinary offering as the UK Government stimulates the economy with its commitment to infrastructure spend.
“We believe our refreshed operating model is well placed to address this need.
“Our Faithful+Gould business enters the new financial year with its diverse portfolio providing an order book that is comfortably ahead of last year.”
CEO Uwe Kreuger said: “We have delivered good results with solid growth in profitability and excellent cash performance. Margin progression has continued towards our 8% goal and the outlook remains positive.”
