We have used THS Concepts for multiple surveys from topographic to drone photogrametry, they are professional and prompt and deliver exactly what is requested. Highly recommended.
★★★★★
I contacted Tom to carry out a Topographic survey, and cannot recommend them enough. Nothing was to much, and I was kept up to date with everything as it happened! Great company to deal with and reasonably priced.
★★★★★
Superb service, quick turnaround and extremely helpful! I wouldn't hesitate to use THS Concepts again if I need to in the future!

Yes. We work across the UK from Essex and London, and take on international projects. Recent overseas work includes Liberia, Jersey, Guernsey and the French Alps.

We are full members of The Survey Association (TSA) and carry public, employers' and professional indemnity insurance.
