Your 'scope' must will be the same across all federations but your entityID can be different in the UK fed if you need it to match an existing entity - e.g. if you are were upgrading from Shibboleth.

Their website should be your source of details for the process:
Here we have the The relevant bits of information about us that you will need to tell them about your 'outsourced IdP' are below. This may be all you need if you are already a member.
Use the entityID displayed in your administration area for the UK fed as described above. E.g.
If the domain name contained within the entityID belongs to the applicant rather than to the external organisation, an explicit statement by the applicant approving the use of the entityID by the external organisation.
If you are a single organisation, use the scope displayed in your administration area for the UK fed as described above. E.g.
