Crown Hosting Services

Contract ID: RM1069

Start Date: 16/05/2015

End Date: 15/03/2019


What can this agreement offer?

Crown Hosting Services (CHS) offer easy to buy, highly efficient, co-location and data hosting on a flexible contract basis using medical grade standard. The facilities are high quality (built to medical standards), secure, 24x7x365. You can take as much or as little space as you need and only pay for what you use.

Co-location facilities provide space, power, cooling, and physical security for the server, storage, and networking equipment of other firms or public sector bodies—and connect them to a variety of telecommunications and network service providers—with a minimum of cost and complexity.

CHS is a single supplier agreement available to all central government departments, arm’s length bodies and the wider public sector buyers. The agreement is with Crown Hosting Data Centres and is a joint venture between the government and Ark Data Centres Limited.

It gives buyers access to co-located physical data centre space - for private or legacy systems.


The Crown Hosting Service offers:

  • access to business critical data centre space
  • a secure environment for legacy or transition to the cloud
  • a flexible, pay-for-what-you-use model
  • power uptime availability that exceeds Tier III (99.982% Availability)
  • leading environmental performance

The agreement supplements the government’s “public cloud first” or “cloud native’ policy. Although “Cloud First” has helped the government move many applications to the cloud, some legacy applications either can’t make the transition in the short term, or are too expensive to switch. This cross-government framework ensures that these applications can continue to be hosted for as long as is necessary, which is secure and cost effective.
