Pre Employment Screening

A pre-condition for any appointment to this role is that you undergo and clear a national security vetting check (NSV) from the Department of Energy Security and Net Zero (DESNZ). It will then be a condition of your employment that you continue to undergo and pass these regularly during your employment. Please make yourself familiar with what DESNZ and these NSV require before you apply for this role. For example, please be aware that the NSV checks are quite intrusive and far reaching including a review of your financial circumstances and the scope potentially expands into your immediate family in addition to your own personal circumstances. Further information can be found on the gov.uk advice page here. In particular, please note that for NSV clearance for this role, DESNZ requires you to demonstrate that you are currently resident within the UK and have been for a continuous minimum of 5 years. If, in making your application to us for this role, you cannot demonstrate this DESNZ 5 year minimum UK residence requirement, we will not be able to progress your application and it will be automatically rejected.
