M&E contractor T Clarke has returned to profit after a challenging 2014.
Profit before tax rose to £3.5m for the year ended 31 December 2015, compared with a £800,000 loss the year before.
The loss had been previously been attributed to a “sizeable loss” suffered in its Mission Critical data and power division.
Group turnover for the period stood at £242m, up 16 per cent on last year, and the company said it had a £300m order book for 2016.
The results were bolstered by particularly strong performance in London and the South-east, which saw division’s turnover increase by 37 per cent to £129m, compared with £94.5m in 2014.
The London and South-east arm was also back in the black after the company posted an underlying profit of £1.5m for 2015, a significant rise on the £1.4m loss the company posted in 2014.
T Clarke also announced that executive director Danny Robson would be leaving the company to “pursue other interests”.
Mr Robson joined T Clarke when his business DGR was bought by the company three years ago and has spent his time overseeing the company’s integration.
T Clarke chief executive Mark Lawrence said: “2015 was a year of progression; still marked by some bumps, but also by increased demand for our services, which was reflected in the improved quality of our order book, first in London and then also in the regions.
“Although the London market has led the upturn in demand, it is also extremely good to report our best ever forward order books across the regions.
”This is highly significant, since it also allows us to be more focused and selective in seeking further work which will, in turn, help us to deliver better value for our stakeholders.”
He added: “We remain alert to any challenges that we may face, yet we approach the future with confidence and enthusiasm.
“The future for the group remains solid.”
