Growth has been driven by continued demand from longstanding client partnerships, the addition of significant new clients, and the expansion of the Group's operations into new territories

The Group also continued to invest capital into the business, positioning TSL for continued growth across its sectors of operation.

"2025 was a year of strong growth across the Group, driven by our valued client and supply chain partnerships and sustained focus on consistent delivery. Turnover increased by 27%, profit grew, and we ended the year with a healthy cash position.

With a strong pipeline confirmed for 2026and beyond, including major capital projects spanning several years, we remain focused on delivering technical construction and engineering excellence for our clients."
