If that blank was missing out the front when it was tested, then thats a C1 (in a domestic anyway, I would be tempted to reduce to C2 if it was in a commericial building within locked plant room, etc) but in domestic anyone could stick fingers in. I know he has flagged up "CU not to Ip4x - C2" but thats refering to the top surface, its the tops of enclosures that should be to Ip4x (and rarely are - but yours looks like all cables enter from the back, so possibly)
The doubling up isn't great, but I don't see any thermal damage?
That CU is a good few generations old, to put it in OCUK forum specific terms, I think 2 megabytes would have been a very good amount of ram when that was fitted! Breakers haven't been available new for a very long time, up until about 10/15 years ago, MK did make a retro-fit kit to fit their newer breakers in that board, but that was at least one generation of MK ago, and then they ceased being in the consumer unit business at the start of this year. Its not the done thing because you shouldn't mix and match, but I do think hager breakers do go in, look completely wrong though, and like I said, it shouldn't be done except as a "get out of ****" temporary solution!
I'd go with a CU change, but I'd advise you to ask for a price for one that includes type A RCDs (commonly called an "18th edition consumer unit") as I think in a few years AC RCDS will be history, if you have fancy PC gear you might also want to consider surge protection which is commonly installed at the CU these days.
Edit: That 40A MCB may be worth a bit to someone on ebay, you could try asking him to leave the board on site for you....
