The Essex based firm saw revenue rise to £65.2m for the year to March 31 2025 from £38m last time as pre-tax profits increased to £2.07m from £839,000.
Cash at year-end also more than doubled to £10.2m from £4.8m.
Steve Wood, Commercial Director said: “These results represent a major milestone for Thomas Sinden.
“We’ve laid the groundwork over several years to build a scalable, efficient business that delivers high-quality construction outcomes collaboratively and consistently. Whilst there is still more work to be done to return to pre-Covid margin levels, we’re on a clear trajectory.
“Our medium-term goal is to achieve net margins of 4–5%, and an increase in turnover to £100m.
“Our strategy has never been about growth for growth’s sake.
“We focus on building long-term partnerships and delivering value in every project. This customer-centric ethos is a key reason why we are consistently trusted with complex, high-quality work in both public and private sectors.”
