Security Clearance Level: DV
Developed Vetting DV is the most comprehensive and highly expensive form of UK security vetting, and is therefore only required for the most sensitive appointments and tasks, involving long-term and uncontrolled access to top-secret material.
The DV Security clearance level is made up of both the Basic Clearance and Security Clearance checks plus:
•the completion of a DV supplement questionnaire
•Security check including a criminal records and credit reference checks, and a Security Service records check
•a financial check
•the checking of references (social, employment, education etc) in writing, by telephone or by interview from personal friends, tutors and employers as appropriate
•a detailed interview with the person needing the clearance conducted by a vetting officer
Once you've passed the interview successfully, Personnel Security will carry out enquiries to ensure you can be trusted with sensitive Government information. Presuming these are satisfactorily completed, you will be granted a Developed Vetting (DV) clearance.
How long will it take before I am DV cleared?
A DV will normally take a minimum of six months on average to complete. The officer assigned your case will keep in touch during their enquiries and do their best to let you know how things are progressing. Because of the time the process takes, you shouldn't hand in your notice to your present employer until DV clearance is granted.
DVs are usually re-investigated after five years and every seven years if there is a continuing need, depending on circumstances. They are renewed annually depending on the employer, and circumstances of the employment.
Will scaffolders have access to top secret material? Well I suppose if the government, police, armed forces etc can leave highly sensitive material on public transport then yes.
