Top right hand side of Pic DP MCB with TWECC coming out at the bottom, looks damaged to me where it bends into the enclosure, or do I need to go to Specsavers?
 
You say Zs across L-N...

What about the true Ze or Zdb?

Could be someone had converted it to TNCS without DNO.

What about a pic of the main earth terminal in the cu? And a wider shot showing all the incoming gear.

Sorry zdb is what I ment. Here is a full pic and there is no main earth terminal. The 6’m gas bond goes from db to the gas meter. There are a couple of dbs that there earths go back to this ‘main’ db. But this main db only has gas bond earth in it. Nothing else

looks like some cowboy has taken a T/E feed from that D/P switch and split the cores.
 
Could be a much smaller cable to the rod. Readings you are getting would not make me think rod though.

Supp bonding from cpc to pipework that is shared with next door's pipework that is bonded and connected to their PME ?
It’s a old detached house which is a fair few meters away from neighbour. I am stumped atm
