International consultant WSP will focus on growth in the energy market in the coming year after posting a pre-tax profit of £28m for the full year.

Chris Cole, WSP’s chief executive, said the firm would strengthen its focus on the energy market after the launch of an energy division last year.

He said: “We’re still seeing strong growth in the sustainability and energy consultancy markets in the UK and abroad, especially in Dubai.”

He added that the group was seeking to make acquisitions, particularly in Australia and mainland Europe.

Proft for the year to 31 December was 35% higher than for the year ended 2005, which was £20m. Turnover rose 20% to £449m in the same period.

Strong results in the property division and acquisitions in the USA and Australia boosted performance. The firm reported that its order book had passed £700m.
