Building Surveyor Director

“I have worked with TSL over the years and have built a high level of trust in the business. Previous large-scale projects with the Major Projects division have enhanced my opinion of their client and solution-focused approach. Having shared experiences with both divisions of TSL, I can see it’s a company ethos which I would have no hesitation in using in the future and recommending to others within the business.”
