That’s the US version of Peacock you’re looking at. The UK one has a truly awful selection.
On NOW you need to get an entertainment membership and go to the “channel” section of the app. In there you need to scroll to the end/bottom where you’ll find Peacock.
Your best to email Sky to see if it will come to Sky/Peacock.

It was added to Disney+ in Australia and New Zealand in November
, it's possible it will be added in the UK at some point once it fully Leaves Lionsgate+
Disney have library deal with Sony who own the distribution rights see see shows like Future Man , Damages and most recently Rescue Me which have been added.
Also getting added to Disney+ Canada on 19th April, does look its getting rolled out across Disney+ regions
BTW a VPN from say Australia and Canada with Disney+ UK subscription easily works to access that countries content which tend to get content earlier
