Im in ireland so no its not grounded...
The air isnt dry enough here to even be bothered with any antistatic precautions
Years of working with computers and components and i have never zapped a part...
As for the blue mats
Got the one on the left and the middle one on amazon.co.uk for pretty cheap... they have places to put screws and stuff and theyre thick and dont slide around in the desk
(Middle one is SUPER shitty... dont get one like it)

The one on the right is brand new and i got it from a supplier of mine but its the exact same as the amazon one just €4 cheaper
I bought this one: Preciva Silikonmatte 500℃ Hitzebeständige Magnetische Arbeitsmatte Arbeitsunterlage Reparatur Matte Soldering Mat Antistatisch für Lötpistolen, Heißpistolen - 45x 30cm https://www.amazon.de/dp/B075D9R8PZ/ref=cm_sw_r_cp_apa_i_gLp5CbM5HYAN5
It was a gift and I can’t find the link to one with the same brand name, but this appears to be the exact one with different branding
Soldering and electronic mat
Anti-Static Soldering Mat,... https://www.amazon.ca/dp/B075D9R8PZ?ref=ppx_pop_mob_ap_share
You can get it cheaper on aliexpress, but I didn't want to wait a month for it
