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.
