How can the fault current be 0.9 KA with a 0.09 ZE fault current to earth will be at least 2.55 KA and most likely more line-neutral.

For those asking for a pic of the CU, I don't live there at the moment. It's got to be done up and it's a 5-hour round trip ? I'll see if I have any somewhere
 
Photo of CU for those asking.

The only think not obvious is the C2 for the IP rating of the CU. Usually that means a hole big enough to get a finger in (e.g. missing blank, but your photo shows that is fine), or smaller one the top where people tend to leave crap that can fall in potentially causing spark/fire.

If it is gaps on the top then it might be that suitable glands could be fitted to seal the unit up. Having said that, if there is going to a an hour or two of work to remove, gland, install and re-test circuits then it might be worth paying the extra £300 or whatever for a new CU at the same time.

Again, more photos showing the top/bottom/side where any holes are would allow folk on here to comment in a more meaningful way.
