What you could be doing | Detective Constable Programme

Investigate the most serious crimes as a qualified detective

Detective Constable Programme

As a detective there is no room for assumptions. Being diligent and collecting evidence based on facts are all part of each line of enquiry you’ll follow. You’ll work on some of society’s most challenging issues including child exploitation, sexual assault and murder. You’ll be driven by your personal mission of working to protect the victims of crime from future harm. You’ll learn about humans, how they behave, and how they shape the fabric of society.

It's a unique role with unique demands that are ever-changing. You need to be adaptable to change and ready to think on your feet. At the same time, it's a role that can give you some of the best and proudest days of your life. From protecting the vulnerable and saving lives, it's exciting, diverse and vitally important.

In return, you will have the benefit of working for a creative, forward-thinking force that is dedicated to keeping Derbyshire a safe place to live, work and visit.

We welcome applications from individuals from all backgrounds and encourage anyone who has considered a career in policing to apply. We are particularly keen to increase the number of women officers and officers from black and minority ethnic communities and candidates from the LGBT community, so that we can truly reflect the communities that we serve in Derbyshire.

As a new detective, you’ll receive an expected salary of £28,551. After seven years your expected salary will be £46,044.

What you could experience as a detective constable

Life as a detective constable is hugely varied. From volume and priority investigations, through to serious crimes. No two days are the same. We asked an experienced detective constable what they could experience in a typical day.



Briefing with the Detective Sergeant, to understand the priorities for the day.



I have new voicemail messages, all from the family of the victim from sexual assault case I worked on Saturday night. They’re calling with what they believe are more leads and evidence for me to look into.


Case updates

Catch up on emails and review previous cases to see if there has been any updates in the past 24 hours from my colleagues on the day shift.


Speak to the family

Return the calls the family of the victims. I assure them I'm doing everything I can to get answers, and I give them my mobile number so they can get in touch with me easily. It's a small gesture and an even smaller comfort, but it brings a little more relief to the family.


Case files

After I get off the phone, I look through my case files and plan the rest of the day. I've got three witnesses to interview, as well as the primary suspect from Saturday's sexual assault scene. I set up the interview for this evening to get as much extra information as I can to help me look for holes in the suspect's story.


Search warrant

I grab a coffee and a bite to eat. With the new information I've gathered, I've got some good leads and ideas of where to look for some key evidence. Have a debrief with the Detective Sergeant and request a search warrant so I can collect the evidence I expect to find.


Suspect interview

Start the suspect interview, their answers are short and somewhat evasive, and it's clear they've been coached. They offer an alibi, but I've got some witnesses who contradict that. I can tell he's not telling the truth, but I want to get more proof to back it up before I call them on it. When the interview is over, I assure them I'm exhausting all leads.


Collaborative working

Call in from the Op’s Team, there’s been another burglary in the same vicinity of a couple of cases I am working on. Update notes and reach out to Police Support Services team to understand if there is CCTV for that areas and can it be released.


Case files

It's been a long day, but I need to update notes on my files and will be in the office for at least another hour, maybe three! I grab another coffee.
