Counter Terrorist Check (CTC) is required for people who will be working in close proximity to public figures, or who will have access to information or material vulnerable to terrorist attack, or whose work involves unrestricted access to certain government or commercial establishments. A CTC does not allow access to, or knowledge or custody, of protectively marked assets and information.
Security Check (SC) is for people who will have substantial access to SECRET assets or occasional access to TOP SECRET assets and information.
Developed Vetting (DV) is the highest level of clearance produced by the the Agency and is required for people who will have substantial unsupervised access to TOP SECRET assets, or for working in or with the intelligence and security agencies.
Im SC cleared in my job -- I work for the Police as an IT specialist , in the force that I work for no financial checks are made at SC level - but that varys from force to force .
DV level is always credit checked .
DV is generally checked every 3 years.
This information is NOT secret and is available in the public domain .

Iam BR and checked with my vetting people before I went BR, I was in the job 2 yrs before going BR.
I would say check with NATS and see what they say - the odds are it will be a CTC check rather than SC or DV .
