NCA/ Civil Service failed pre-employment checks

I recently had a provisional offer withdrawn after I failed the pre-employment checks.

Going into the role, I already held UK Security Clearance and an enhanced DBS.

The NCA hold their own checks on top of this.

They said I was welcome to re apply in 12 months but they won't say what failed me and I am genuinely stumped for ideas.

Here's my question:

Has anyone failed pre-employment checks and been successful when they applied a second time..?

I spent a lot of time and money (days off work, train fares for interviews/medicals etc) and am unsure whether to apply again if the reality is I'll only fail due to a red flag in my past. Not knowing what failed me I can't correct it.

Thanks.

Off the top of my head I was contacted via email about a month after submitting the forms to say that I had passed the first stage of their vetting, then about three weeks after that I had a further email withdrawing their offer as I 'hadn't met their standards'.

Wow that is so not cool. It's such a long process from filling out applications form and all interviews, them being offered a position just for it to be withdrawn without telling you why. We put our lives on hold waiting for the job. It's really not fair. I'm waiting on pre employment checks for Border force UK. I kind of losing hope by now. Best of lucky for you, something even better will come up to you x
