The 13% jump in revenue also saw the firm turnaround portability generating a pre-tax profit of £2m after a £33,000 loss in 2022.

Managing director, Kevin Valentine, said: “Our focus is on establishing a sound financial footing that will support long-term growth and create opportunities for our people.

“I’m delighted we’ve been able to break through the £100m barrier, which has been an ambition for several years. It speaks of the hard work undertaken by our teams and the ambition we all have for the success of our business.”

Knights Brown’s portfolio includes a strong presence in ports, coastal engineering, energy, local government infrastructure, water utilities and industrial buildings.
