Our Management Team

Responsible for leading the Cellnex UK business, our management team is committed to developing collaborative partnerships with customers, portfolio partners and stakeholders across the industry – driving innovation and growth, and creating value for all in today’s connected world.

Following the acquisition of Arqiva Services Limited by Cellnex UK, “On Tower UK Limited” is born to integrate into the current structure of Cellnex UK. Having said that, we are now in a transition period and this page will be updated as and when we integrate.

Bringing experience and innovation together. The story so far…
