What happens to Part P notifications?

[pc1966]

I guess this might seem like an odd question, but what do the Part P notifications actually do?
That is, beyond the goal of stopping dodgy work by folk with little or no electrical knowledge, do building control use them for anything? Can you use them to check on past work on a property you are interested in, etc?
Also related to this, if an ECIR shows anything serious is that sent to building control as well? (e.g. so you could see if something was needing done, and then if corrective work was later notified)

Part P notification is simply meant to show compliance with building regs and Bs7671.
