I often hear these types of conversations in the local Screwfix, and have to keep saying to myself "just keep out of it...."

In my area we have quite a few of these guys. You tend to hear them discussing various problems and faults with each other in the wholesalers.

I don't see any need in replacing the DB, is it a starbreaker board? Why not just replace the MCB with an RCBO,
without seeing the job it's hard to gauge on the fairness of the quote given, personally from reading the work i think it seems a bit pricey but each to his own.
