No i didnt do any testing before i started as it was an old wylex fuse box all the wires were short and twisted together.

Unfortunately this is the fatal mistake. As much as its a total pain in the back door, it really is worth testing it to make sure it's ok, at least do global IR readings.

The issue now is that you have a board you cannot get to hold.

I ripped one out for a mate last year, it was rammed behind a cupboard and it was a non starter testing it, I got there at 8am, and didn't go home until 4am the next morning.... My stupid fault!

As for the cert, no you need to correct the problem and issue an EIC and notify, this really is the only option.

A few of you seem to be suprised about the none rcd side comment.
Usually a 17th dual split board as 5 x 5 rcd protection and then you get a 2way busbar that offers the option fror either a mcb or rcbo.
I always budget for 2 additional rcbo's one for the boiler and one for the cooker so in the event of a fault at least they can keep warm in the winter, have a bath and cook a meal.
I am good me.

Hi Integrity boards should be made mandatory IMHO, far far better for now and the future
