PSN Core Services

Buy Domain Name System (DNS) services that allow government users of the Public Services Network to send electronic information securely.


This agreement provides Public Services Network (PSN) Domain Name Server (DNS) services that reconcile website names and their underlying IP addresses and allow the government and the wider public sector to send digital information securely.

The agreement has been developed in collaboration with the Government Digital Service and will replace the Government Convergence Framework (GCF) DNS service which will end on 31 March 2021. If you are a user of the GCF service will need to re-contract and migrate to this replacement service.

The PSN is the government’s high-performance network, which helps public sector organisations work together to share information and resources and reduce duplication. 

A DNS maintains a directory of website names (known as domain names), for example,, and translates them into IP (Internet Protocol) addresses. This is necessary because computers and machines don’t understand website names and need an IP address to access a website.

How to buy

This service is available to current users of the GCF DNS service. You will need to migrate to the new service before 31 March 2021 and CCS are working with the newly appointed supplier, Nominet, to implement and beta test the new PSN DNS service so that we can begin the migration to a live service.

When we are ready, CCS and Nominet will engage with you directly to complete your new call-off contract and give you instructions on what you need to do to migrate to the new service.
