What our clients say

Below are a few snippets of glowing feedback from our valued clients.
  • Vodafone

    Project Manager
    National Grid - Vodafone Project (OPTEL)
    If it had not been for the way that GTDS staff were flexible, proactive, and professional, combined with the high quality of the installations, we would not be where we are today.
    Nothing is too much trouble for them.

    Please pass on my thanks and appreciation to the GTDS team for achieving this TOTT CB380 NOMS output.


    Senior Project Manager
    National Grid – Bramford 400kV Substation
    I just wanted to thank you. Your guys were excellent, and our guests left with a very good impression of how the ongoing works at site are being delivered. Can you please pass my thanks on to the team. On a side note, it was great to see how well managed and tidy the site was. If I was undertaking a spot-check in my old capacity as LPM, or a safety visit, then there would be nothing negative to report. Great to see; well done!
