A bit about us...

Colt smashes NPS target with industry-leading score

Colt ended 2019 on a high with its best-ever Net Promoter Score (NPS) of 64 points in Europe. In Asia we closed the year on 26 points. Both these scores are truly industry-leading, with Satmetrix 2019 B2B benchmarking the EMEA and Global Telecoms sector at 15 and the Asia Telecoms industry at just four.

Colt powers Illuminated Rivers through London

The Illuminated River Foundation was set up to transform the River Thames into a ribbon of light that weaves it way through the heart of the city at night. Four of its bridges — London, Cannon Street, Southwark and Millennium — were illuminated in the first phase of the project in July 2019. Five more bridges will be lit in Spring 2021, creating the world’s longest public artwork (3.2 miles) that will be viewed 90 million times a year over 10 years.

ESMIG (T2-T2S consolidation)

Since 2012, SIA, in collaboration with Colt, has been the provider of Eurosystem infrastructure access services and boasts a robust track record in delivering mission critical services to the European financial community.

"The Colt infrastructure is robust, Colt controls it end-to-end, and we get excellent support from our account and service managers who really understand our business."

Amanda Thomas

VP Telecoms EMEA, Intercall

"The overall evaluation of the service received is positive in two ways: first, due to the technical quality of the product in terms of its strength, consistency and security, and second, in terms of the advice and assistance received during both the pre- and post-sales stages."

Javier Bartolome

Technology Director, IMSolutions

"Colt has been a real partner throughout the years we've been working together, always ensuring that its services have kept pace with growth in our business. The people I deal with directly at Colt understand my needs. We have a smooth, efficient relationship."

Marc Conte

SVP of IT, Louvre Hotels

"We know that Colt focuses on enabling its customers to meet their goals, rather than purely technological aspects of any project. This philosophy fits excellently with the service understanding of the [Berlinale] festival"

Dieter Kosslick

Director, Berlinale
