There is a 60 day service level agreement on DBS applications from the moment they reach Stage 4 (LPF - Local Police Force). Only after 60 days at Stage 4 can the application be chased. Until this point, the application cannot be classed as delayed.
It is in fact a little more complicated than that as the local police force may send it back to the DBS with a query and the DBS may go back to the local police force, at which point the 60 days starts again.
Atlantic Data will look to automatically escalate an application once these 60 days have elapsed but the applicant may also wish to make contact with Atlantic Data to ensure this is the case.
Many applications can take some time to receive their results. There is not necessarily anything wrong if a result does take this long to come back, it just depends on the backlogs at the various police branches and organisations involved in performing the checks, and/or what type of/how much information is revealed on the applicant’s certificate, if any - the fact that an application is taking longer does not necessarily mean there will be information revealed on the certificate.
In rare instances the DBS will have contacted the applicant to request some more information for the purposes of identity confirmation – it is always worth checking with the applicant whether they have received anything in this regard if an application is taking unusually long.
If you wish to query the delay you can either contact firstname.lastname@example.org or call the DBS directly on 0300 0200 190 (any option barr 1).
