To see why some of the worlds leading businesses are choosing Stellium as their data centre operator of choice, book a guided virtual tour of our Newcastle facility here.

Why Newcastle

There are many reasons to choose Newcastle as your data centre location of choice. Why continue to locate in congested London with increasing power costs and repeated issues with infrastructure when:

  • Stellium provides 80 MW’s of power at Stellium 1 Newcastle
  • Stellium provides metered power contracts – in London the infrastructure to give metered contracts is not available. Energy is now 70% of your colocation cost so this is a major issue for your business in terms of transparency.
  • Stellium provides mobilisation time for contracts up to 1.3MW in 4 weeks
  • Stellium has no latency congestion. In fact we provide some of the lowest latency now available in the UK. As the landing station for the latest international subsea fibre cables, Newcastle is now closer to New York than the capital is.
  • Stellium has no cooling issues – unlike London data centres who experienced major cooling issues in 2022, Stellium had none.

Stellium is where sustainable colocation, global subsea and terrestrial communications converge

Stelliums Northern Powerhouse location in Newcastle has emerged as a major UK interconnection hub and the meeting place for data-transfer east and west, as well as locally and nationally.

Stellium is the UK’s cable landing station for the new international subsea cables from Aqua Comms, the new Nordic subsea cables from Altibox/NO-UK and the home of the UK’s newest Internet Exchange Point NCL-IX.


Available space

Covering an area of more than 4,264m2 and divided into four 4MW IT data halls whilst being fully scalable, it’s one of the most efficient colocation data centres in the UK.
