@th Don't those QR codes containt he numbers you've blanked out? And is that thing really a 3-phase meter; 3-phase is rare in the UK in homes.
its fairly normal to get 3 phase to domestic houses on the Continent, and the electric cooker to have the supplies for the hobs, grill and over split across L1, L2 and L3 (a cooker I had installed in my house in 2014 had terminal straps so it could be either used on single or 3 phase connections)
