From my experience, it seems that there isn't enough recognition of the CBIP certification in the UK. The best measure of this is to compare the number of data warehouse / BI jobs advertised here in the UK and US.
In the US
Lets try Monster - It throws 3 jobs with CBIP as a requirement or prefered
At Jobster - it has 7
In the UK
Monster - 0
At IT Job Board - 0
Any given day, you will find similar trend - definitely recognized in the US, but not in UK. Wonder why that is? Not enough marketing/awareness building by TDWI
