UK Data Centre needs to support your whole business. But how can you be sure it’s truly as robust as it claims to be? OCSL’s infrastructure, utilities, site and server security hold the highest levels of accreditation. But it’s our client feedback that truly underlines our excellent reputation.

Many data centre clients choose OCSL because their peers confirm we deliver on our promise. Our deployment is fast. Goals and timelines are clearly defined. Expectations set out in detail.  Scalability is everything and here too we stand out from the crowd. From on premise infrastructure to Colocation to the Cloud, we offer scalability exactly when you need it. We engage with you to understand your issues and goals. We help you create roadmaps that set a clear direction.
