New SkyID or Add to Existing?

[1980ni]

We have Sky Q in our main home, and looking to put Sky Stream into our second home.

Am I best to call Sky to add the Stream/Broadband onto our existing SkyID for the new subscription or just set up a new ID?

Would I be offered new customer price if I call them to add the existing id?

Really don't want to have 2 IDs.

@1980ni  It's not possible to place an order for a second address under an existing Sky ID if there is a live account at your current address, you'll need to sign up under a different email address creating a new Sky ID for your 2nd home.
