Do you pay a subscription for each mini box or does one subscription cover multiple mini boxes ?

I have a multi room subscription and currently one mini box. I'm looking at putting another in my daughters room will I need another subscription or will my current multi room subscription cover both boxes?

No

just the admin fee to get the extra box delivered

You can have a maximum of 4 mini boxes loaned to you by Sky. You can watch Sky content on two minis and the main box at the same time. You may be able to use a third mini box if the first one in use is being used for a streaming app ie: Netflix or DIsney+.

Be aware the original 1TB (non-UHD) Sky Q box only allows one mini to be in use. To check if you have the non UHD 1TB box check in:-
Home - Settings - System Info - Hardware Version
If it shows as 32Cxxx then you have a non UHD 1TB that only supports 1 active mini box.

All 2TBs and the UHD/HDR 1TB permit two mini boxes. Each mini box which is loaned to you may be subject to a one off upfront charge but you only need one Sky Q monthly Multiscreen subscription.

Good reminder on the early 1TB box limitation.
