Bouygues UK has been steadily reducing revenue in recent years as its focusses on more selective bidding.
The firm, which employs 1,230 staff, managed to generate a £2.35m pre-tax profit from revenue down 11% to just under £400m, with operating margins at 0.5%
Bouygues ended the year with £198m cash up from £153m previously, strengthened by a parent group loan of £48m.
The UK construction group’s development arm BY Developments contributed around £102m to revenue and £2.7m pre-tax profit.
Group chief financial officer Jean-Luc Midena, said that while the company was impacted by the lockdown, Bouygues UK was in a strong financial position given its substantial order book, strong cash position and positive net assets.
He said that while no subcontractors had to date failed, Bouygues was keeping key supplier monitoring in place, with regular checks being carried out with supply chain members.
