Civilian Police Investigator Jobs Explained
No warrant card, no arrest powers, but a route into investigating crime for UK police forces. What the role actually is, PIP1/PIP2 explained, a sourced pay example and the limits on what you can do.
A civilian (or "designated") police investigator is a police staff employee, not a sworn constable, who investigates crime using powers designated to them by their chief officer under the Police Reform Act 2002 (as amended by the Policing and Crime Act 2017). No warrant card and no power of arrest or stop and search. But real casework, PIP accreditation in some forces and a way into policing without joining as a constable.
What a civilian investigator actually is
Chief officers can "designate" police powers to police staff who aren't warranted officers. Since the Policing and Crime Act 2017 the formal designation is "policing support officer" and roles using it are called different things depending on the force, such as Designated Investigator, Police Staff Investigator, Investigating Officer or Civilian Investigator.
These roles exist because investigating a case involves a lot of work that doesn't require a warrant card: reviewing evidence, taking witness statements, building case files, liaising with victims and preparing files for court. Designating this work to police staff frees up warranted officers for the parts of the job (arrest, use of force, custody) that only a constable can do.
The legal mechanism is section 38 of the Police Reform Act 2002 as amended by section 38 of the 2017 Act, under which a chief officer can confer any constable power on a policing support officer other than the powers excluded by Schedule 3B. It's a deliberately flexible model: a chief officer decides which powers a given role needs, so the exact powers, job title and pay for what looks like the same job can differ between forces.
Civilian Investigator vs PCSO vs Constable
One of the most common mix-ups in this space. All three can be police employees working alongside each other, but they're structurally different roles.
| Civilian Investigator | PCSO | Constable | |
|---|---|---|---|
| Employment status | Police staff | Police staff | Warranted officer |
| Warrant card | No | No | Yes |
| Core focus | Casework, evidence, case files | Visible community patrol | Full operational policing |
| Power of arrest | No | No (some designated powers, such as short detention, vary by force) | Yes |
| Powers set by | Designated by chief officer (PRA 2002) | Designated by chief officer (PRA 2002) | Common law and statute |
| PIP accreditation | In some forces (PIP1, some to PIP2) | Not normally | Yes, for investigators (PIP1–4 by role) |
Powers for PCSOs and policing support officers are designated under section 38 of the Police Reform Act 2002 (see Schedules 3B and 3C) and vary by force. Source: legislation.gov.uk; College of Policing framework documents.
What they can and can't do
Under section 38 of the Police Reform Act 2002 (as amended by the Policing and Crime Act 2017), a chief officer can designate almost any constable power to a policing support officer, with specific exclusions written into Schedule 3B. Which powers a given role gets depends on the force and the job description.
Examples, depending on the role
- ✓Taking witness and victim statements
- ✓Reviewing and building case files for court
- ✓Seizing evidence, where that power is designated to the role
- ✓Entering and searching premises, where designated and trained
- ✓Interviewing suspects under caution (specific roles, with training)
- ✓Liaising with victims and witnesses throughout an investigation
Always excluded by law
- ✗Power of arrest
- ✗Stop and search
- ✗Acting as custody officer when none is readily available (PACE s.36(4)); police staff can still be designated as staff custody officers
- ✗Powers only a constable of a particular rank can exercise
- ✗Powers under counter-terrorism and national security legislation and applications for Investigatory Powers Act surveillance warrants

PIP levels: 1, 2, 3 and 4 explained
PIP, the Professionalising Investigation Programme, is the College of Policing's investigator accreditation framework. The College's PIP 2 profile applies to officers and staff and some forces train police staff investigators to PIP2, the level for serious and complex crime. PIP2 needs a pass in the National Investigators' Exam, which police staff investigators sit too.
| Level | Covers | Typically held by |
|---|---|---|
| PIP1 | Priority and volume crime | Response officers and civilian/designated investigators |
| PIP2 | Serious and complex investigations | Detective constables and civilian investigators trained to this level |
| PIP3 | Senior investigating officer (SIO) role | Senior investigators, typically experienced detectives |
| PIP4 | Strategic investigator level | Senior investigators in strategic roles |
Source: College of Policing investigation professional profiles (PIP levels).
How PIP accreditation actually works
PIP accreditation isn't a single exam you sit and pass. It combines learning and development for the level with a portfolio of real casework that shows you can meet the assessment criteria.
For PIP2 specifically, the College says you must pass the National Investigators' Exam (NIE) and then obtain PIP2 registration through PIP2 learning, development and portfolio submission. It builds on PIP1 and maintaining registration means continuing to show competence and recording CPD.
Because this is workplace-based, timeframes vary by force, by caseload and by how the specific role is structured: some civilian investigators are recruited already PIP-accredited from a previous role, others are trained up from PIP1 to PIP2 over time once in post. Always ask about the specific accreditation pathway and expected timescale at interview, since it isn't standardised UK-wide.
What these jobs are actually called
Job titles vary a lot by force. Titles used for this kind of role include:
Crime coverage spans volume crime, fraud, cyber-enabled crime, safeguarding and, at PIP2, serious and complex cases. The common thread: no warrant card and a focus on evidence, statements and case file preparation rather than physical enforcement.
Specialist investigator tracks
Not every civilian investigator post is generalist. Two specialist tracks may suit candidates from outside policing, because the skillsets exist in other sectors.
Financial Investigator
Financial investigators work fraud, money laundering and asset recovery casework, often under the Proceeds of Crime Act 2002 (POCA). Some hold Accredited Financial Investigator (AFI) status, a national accreditation that allows use of certain Proceeds of Crime Act powers. Backgrounds in accountancy, banking compliance or fraud investigation can be relevant, but check each advert.
Digital Investigator
Digital investigators focus on digital forensics and cyber-enabled crime: recovering, preserving and analysing evidence from phones, computers and online accounts in line with established digital evidence handling principles. Backgrounds in IT, computer forensics or cybersecurity can be relevant and roles may carry technical accreditation separate from PIP. Check each advert.
Pay: a published example
Unlike police officer pay, which follows a single national scale, police staff pay (including civilian investigator roles) is set locally by each force. There's no single UK-wide table, so here is one published example rather than a claimed average:
Starting salary £29,085 (pay point 25). Progression beyond pay point 27 (£30,783) depends on PIP2 accreditation, per the force's careers page. Figures on force pages can pre-date the latest staff pay award, so check the current advert.
We have no verified UK-wide average for these roles, so we don't quote one. Always check the specific force's own advert.
Pension: not the police officer scheme
Because civilian investigators are police staff rather than warranted officers, they're typically enrolled in the Local Government Pension Scheme (LGPS) rather than the Police Pension Scheme reserved for constables. LGPS is a career-average scheme with its own contribution bands: worth understanding separately if you're comparing this route against joining as a warranted officer, since the two pension schemes are structured quite differently. Always confirm the exact scheme in your specific offer letter.
Contract type varies
Some adverts for these roles are fixed-term and others are permanent. We haven't found a national figure for how common each is, so treat contract type and length as something to confirm on the specific advert you're looking at.
If a post is fixed-term, ask directly at interview why and what typically happens at the end of the contract.
Why forces use these roles
According to HMICFRS inspection data, the number of accredited PIP2 investigators in England and Wales rose from 20,356 to 22,832 between March 2018 and March 2024, but the shortfall against the number needed more than doubled, from 4,353 to 9,441. Many in policing link the wider use of civilian and designated investigators to that pressure, using police staff to take on casework that doesn't require a warrant card. That link is a commonly made argument rather than something we have verified officially.
Can this lead to becoming a police officer?
For some people, yes, though it's not an automatic conversion. We haven't found a national "civilian investigator becomes constable" pipeline. But the experience isn't wasted if you later decide you do want a warrant card.
The nearest recognised link is the Police Constable Entry Programme (PCEP): some forces accept serving PCSOs, Special Constables and investigation officers who meet the force's own conditions, which can include a minimum period in post, in place of the usual Level 3 qualification. Check the force's PCEP page. PIP accreditation and casework experience can also be useful evidence in a later police officer application.
Equally, plenty of people take civilian investigator roles because they specifically don't want to be a warranted officer: the appeal is investigative casework without the operational, shift and use-of-force elements of frontline policing. Both are valid reasons to consider the route; know which one applies to you before you apply.
Weighing it up honestly
Genuine advantages
- ✓Investigative casework and PIP accreditation in forces that offer it, without going through constable recruitment
- ✓No requirement to carry out frontline uniformed patrol or use-of-force duties
- ✓Can suit candidates with relevant sector experience (fraud, digital forensics, safeguarding) who don't want to start as a generalist constable
- ✓Experience that may help a later police officer application and PCEP entry in some forces if you meet their conditions
Real trade-offs
- ✗Some posts are fixed-term, which offers less job security than a permanent post
- ✗No arrest, stop and search, or other core constable powers: you'll sometimes hand a case to a warranted colleague at the enforcement stage
- ✗Pay and progression set locally, so no national scale or guaranteed parity between forces
- ✗Job titles, powers and accreditation pathways are inconsistent between forces, making it harder to compare roles like-for-like
Common myths, corrected
How to apply
For what current adverts ask for (entry-level and PIP 2 posts), vetting, training to PIP 1 and practice interview questions, see our police staff investigator interview guide.
These roles are recruited by individual forces, not through the national police constable application process. Search each force's own careers or jobs page directly, since vacancies open and close throughout the year. Requirements vary: Derbyshire Constabulary, for example, asks for a role-relevant degree or a recognised investigative qualification, three years' UK residency and vetting clearance, while other posts may ask for sector experience.
Police staff recruitment is run by each force and usually includes an application, an interview and vetting; the vetting level depends on the post. Some posts may add a written or scenario-based assessment. Check the advert and person specification, since processes differ by force.
Because contracts and vacancies vary by force and change frequently, treat any single force's process as an example rather than a fixed template: always read the specific advert and person specification for the post you're applying to.
