Does consumer unit need replaced?

So no electrcitiy at the house. My rcd kept tripping when isolator was on and all breakers off. So maybe a rcd issue.

Had no power so managed to get an on call electrician around to just get power working as no power to the property.

He bi-passed the rcd, power is restored. He said to get the whole consumer unit replaced because it's a mess.

Do you guys agree? Or is it worth just getting rcd fixed replaced.

I will contact my regular electrician, but appreciate any other views.
