Police Constable
Full Time

We welcome applications from Police Constables and Detective Constables for opportunities to join Counter Terrorism Policing South East (CTPSE) as Dedicated Source Handlers to run Covert Human Intelligence Sources (CHIS).  

This is a unique and exciting role to be a part of a proactive team engaged in combating the threat from International Terrorism, Right Wing Terrorism (RWT) and Left wing, Anarchist and Single Issue Terrorism (LASIT) across the UK and beyond.

Having successfully completed your two year probation period, your success in this role is dependent on your character and your excellent communication skills. Your police service and experience so far is less significant than your ability to build rapport with people from a broad and diverse range of backgrounds from the first time of meeting. Your ability to demonstrate empathy and your emotional intelligence will help you to gain trust and in turn elicit information that could be pivotal to the success of a National Security operation or the safe management of significant risk.

You will identify, recruit and handle CHIS to provide intelligence in support of initiatives aimed at preventing, disrupting or detecting Terrorism. Your role will include; developing, tasking and applying appropriate levels of trade craft in the management of CHIS. You will also be responsible for exploiting intelligence opportunities and the sanitising and recording of intelligence in accordance with changing threat picture. 

You will also act as co-handler where appropriate to those other sources utilised by the Security Services.

You will have a good working knowledge of modern day policing, with an interest and understanding of covert investigations and have an investigative mind-set. This will include an excellent working knowledge of Information Technology and online Social media.

A working knowledge and understanding of legislation in relation to the Regulation of Investigatory Powers Act 2000 (RIPA), European Convention of Human Rights (ECHR) would be an advantage but is not essential. If successful, full training will be provided in these areas together with CHIS Codes of Practice which will all be integral to the role.

In this role you will act as a professional point of contact with regard to CTPSE CHIS related issues and where appropriate, act as a point of contact for other Police Forces and associated agencies such as the Security Services.

Hours of duty will be as required to meet operational needs including call-out, working a basic shift pattern dependant on the location and role selected. Periods away from home may be required on rare occasions.

Please note that although this role is currently based Near Gatwick, we will be vacating our current premises by Autumn 2022, and roles will move to alternative sites. Detailed planning work is ongoing to identify interim and long term options, which will include planning for growth and development of Counter Terrorism Policing in the South East into the future.

CTPSE are committed to becoming the most diverse team in the South East. We encourage interest and applications from candidates of all backgrounds and particularly welcome applications from female and BAME (black, Asian and minority ethic) candidates to enable us to truly reflect the communities we serve.

Due to the role requirements, it is essential that the post holder be prepared to be security cleared to Developed Vetting (DV) level. This will be required for the duration of the role. Furthermore, due to the nature and sensitivity of work carried out we require that candidates not only hold this vetting level but that they also undertake additional security clearances which include additional nationality checks. This post is therefore restricted to UK nationals. This is line with government requirements, supported by Cabinet Office policy and Section 82(2) to (4) of the Police Reform Act (2002), and is for the purpose of safeguarding national security, to ensure that any potential vulnerabilities are identified at an early stage.

Following a successful paper-sift the candidate will be required to:

  • Attend and pass an external third party Pre Training Assessment (PTA) centre, date TBC.
  • Attend an internal interview following the above assessment, date TBC.
  • Attain Developed Vetting (DV).
  • Attend and Pass the 5 week National Security Agent Handling Course* (NSHAC).
