You still have an IP rating to meet

I am not questioning your reply Adam but if the OP installed the CU in 2006 surely it would have conformed to the IP ratings at the time? The OP stated that he has completed the installation by converting to all RCBOs by doing so is he obliged to update to an additional standard? As he has not changed the actual CU I would have thought the standards of the day would still apply even if they do not meet current standards. The only obligation I can see he may have is that if he has removed cables resulting in open entry points that they may need blocking but his post does not make that clear.

Yes, the electrical works were described on the full plans passed in 2006. So I am doing it to 16th edition. There is of course no end date for building regs works. But I have to get electricals finished and certified to get the building regs signed off.

I get the point that to those regs the cable seal is not for fire rating (the plastic box would melt) but for IP rating and particle ingress, etc.

I have added/modified some circuits since 2006, but that does not mean the box itself has to be upgraded to latest regs metal box, etc. (I hope !)
I never sealed the cable entries since 2006 ...
