Northampton contractor Winvic has expanded its multi-room building business with five projects of £20m-£45m value in the Midlands.

An increase in project size in its traditionally strong industrial market has also helped to raise turnover 5% to £485m, generating a 10% uplift in pre-tax profit to £31m in the year to 30 January 2018.

The firm now boasts an operating margin of 6.4% from a staff headcount of around 200 employees.

Managing director Simon Girardie said: “The group’s prospects look very positive got 2018 with a forward order book of £590m with a pipeline of secured contracts across our five key operating sectors, including £110m within multiroom.

“We are confident of another good year and we envisage our financial year ending January 2019 will produce a consistent growth in turnover forecasted at £650m.”

He added that the group’s key industrial market would remain a core sector amid a trend towards larger projects and multiple unit contracts.

“With the ever-increasing demand for consumer delivery services, we expect to remain the leader in the industrial market, increasing the number and value of projects from both new and repeat business clients.”
