Surveillance and
Covert Roles
What official sources say about joining police surveillance teams, technical surveillance units and undercover work: the selection steps, courses, psychological assessment, vetting, the law and oversight. We describe only what the College of Policing, the Home Office and other official bodies publish.
Independent information, not advice · Sources checked 18 October 2026 · England and Wales unless stated
These are internal posts for serving officers, recruited by each force or regional unit. For surveillance teams, a BTP officer writing for the College of Policing described pre-selection, advanced driver training and a pass or fail course against national standards, leading to licensing as a surveillance operative. Undercover officers volunteer and go through College-licensed selection with personality or psychological assessment. Many covert posts need management vetting. Selection details are not published, so ask your force.
What this page covers, and what it does not
Covert policing depends on not publicising how it works, so most selection detail is restricted. This page sticks to what official bodies publish: the College of Policing's public guidance and role profiles, a College article by a serving surveillance officer, the Home Office codes of practice and the oversight body. Where we could not confirm something, we say so rather than fill the gap with guesswork or second-hand accounts.
If you are applying for covert work, treat your own application as sensitive. Do not post about it on social media, and be wary of anyone outside policing offering inside knowledge of covert selection.
The roles, as the College groups them
The College of Policing's intelligence profiles group covert work into four families. Some profiles are public; others need a College Learn login, which only people working in policing have.
| Role family (College profiles) | Example roles listed | Profile public? |
|---|---|---|
| Surveillance | Technical surveillance officer; technical surveillance unit team leader; head of technical surveillance unit | Yes, on the College website |
| Covert operations | Covert human intelligence source handler, controller and authorising officer | College Learn login only |
| Serious and organised crime (covert) | Undercover foundation officer; undercover advanced operative; undercover online operative and online only operator; protected persons practitioner; covert operations manager | College Learn login only |
| Intelligence | Intelligence officer, researcher, analyst and support officer; intelligence supervisor and manager | Yes, on the College website |
Each profile sets out responsibilities, the expected Competency and Values Framework levels, core skills and the "education, qualifications and experience" for the role. If you are serious about a covert post, ask your force or unit for the full profile; it is the clearest statement of what the sift will look for.
Surveillance teams
The most detailed official account we found is by a British Transport Police officer with 17 years as a dedicated surveillance officer, published by the College of Policing in August 2024. It defines surveillance as "the close observation of a person or persons suspected of criminal behaviour", carried out to "gather intelligence and evidence about suspects to assist investigating teams, and support successful prosecutions".
"To join our team, officers are required to complete a robust, national process. This includes pre-selection, advanced driver training and attendance on a pass/fail course with assessment against national standards. On completion of the process, successful candidates become licensed surveillance operatives."
Points worth drawing out:
- It is a supporting role. In BTP's dedicated unit, "the surveillance operatives do not investigate the crimes" but work alongside major crime, serious organised crime and sexual offences teams.
- Driving matters. Advanced driver training is part of the process. The police driving prescribed training regulations also include a pre-surveillance motorcycle riding course, valid for two years with a two-day refresher.
- The course is pass or fail and assessed against national standards, so a place on it is not a guaranteed post.
- Attachments help. The officer describes getting an attachment with the team before joining full time.
The account is one force's experience. Eligibility rules, such as minimum service or driving qualifications before you apply, are set by each force or regional unit.
Technical surveillance
Technical surveillance is a separate specialism, with a public College profile. It says the technical surveillance officer "provides covert technical surveillance capabilities for operations". Responsibilities include site surveys, installing, maintaining and extracting equipment, advising senior investigating officers, and producing evidence that conforms to disclosure principles under the Criminal Procedure and Investigations Act 1996.
- Previous qualifications: "None required."
- In role: successfully complete the technical surveillance unit (TSU) core skills (D7) course, then further D courses relevant to your specialism.
- Staying accredited: do the role operationally or in an appropriate exercise, in line with the College's licensing requirement for the courses attended.
- Competencies: CVF level 1 (practitioner) for most competencies, but level 2 for "we analyse critically".
Counter Terrorism Policing advertises technical surveillance and surveillance support roles, including constable posts, on its careers site.
Undercover officers
The College of Policing publishes a public version of its undercover policing APP (February 2021). It notes the guidance will be updated to reflect the outcomes of the ongoing Undercover Policing Inquiry. What it says about joining:
- "UCOs volunteer for selection, vetting, training and accreditation."
- "The College of Policing licenses all undercover selection processes and undercover training courses", delivered to national standards.
- At publication, "the foundation programme was the single point of entry", with direct access to advanced level being developed.
- Only accredited units can deploy undercover officers, at foundation, advanced or online level.
| Category | What the APP says it does | Selection assessment |
|---|---|---|
| Undercover foundation operative (UCF) | Deployments that do not need significant backstopping (supporting a covert identity with documents and facilities). Can add modules later, for example online or street drug buyer. | Personality assessment with an occupational psychologist provided by the College |
| Undercover advanced operative (UCA) | Deployments where a significant level of backstopping is needed. | Psychological assessment with a chartered clinical psychologist or registered psychiatrist |
| Undercover online operative (UCOL) or online only (UCOLO) | Online deployments. UCOLOs are restricted to online work only. | Psychological assessment (online only selection) |
Psychological assessment
Selection includes a personality assessment for foundation candidates, which "evaluates a candidate's motivation, suitability and resilience for the UCO role", and a psychological assessment for advanced and online-only candidates: "a semi-structured one-to-one interview session with a qualified practitioner (a chartered clinical psychologist or registered psychiatrist)". Assessment continues once in role: every six months for advanced operatives, every three months for those in very stressful roles such as investigating online child abuse, and on a risk basis for foundation operatives.
Staying active, and tenure
To stay deployable, an undercover officer must have deployed or done CPD in the last 12 months, sign the undercover code of conduct every year, have the regular psychological assessments and be supported by their covert operations manager. Otherwise they are recorded as dormant and need a development plan to return. On tenure, the APP says "a fixed-term tenure cannot meet the needs of all undercover units and operatives", so officers are assessed under a risk-based tenure policy.
Vetting for covert roles
The College's vetting APP (May 2025, 5.4.2.f) lists, among posts that need management vetting (MV), people who "have access to sensitive intelligence as part of an investigation (for example, serious and organised or major crime units)", informant handlers, and those working in counter corruption and counter terrorism. MV adds full financial checks, needs five years' UK residency and lasts seven years, maintained through annual reviews.
Counter terrorism roles may also need national security vetting. Counter Terrorism Policing says it "may take up to six months – or longer" and needs UK residency of "a minimum of five years at SC level and 10 years at DV level". See police vetting levels explained.
The law and oversight
Covert policing is tightly regulated, and selection panels expect you to understand the framework:
- Authorisation: directed surveillance and the use of covert human intelligence sources are authorised under Part 2 of the Regulation of Investigatory Powers Act 2000.
- Codes of practice: the Home Office publishes the covert surveillance and property interference code of practice (revised codes took effect on 15 August 2018) and a separate code for covert human intelligence sources (revised 13 December 2022).
- Oversight: the Investigatory Powers Commissioner's Office oversees "the use of covert investigatory powers by more than 600 public authorities", including police forces, and checks that the powers are used in accordance with the law.
- Disclosure: evidence from covert work must still meet the Criminal Procedure and Investigations Act 1996, as the technical surveillance profile spells out.
For the detail, see our guide to disclosure, RIPA and CHIS.
What the work asks of you
The BTP officer is candid: "There can be times when we don't know what we are doing from one day to the next or the deployment we are told we are on changes at short notice. The hours can be long too", though the team "can, and do accommodate flexible working". The work is driven by intelligence and by what the subject does.
For undercover roles, the College's APP puts welfare and psychological support at the centre, from regular assessments to cover officers responsible for each operative's security and welfare. If you have caring responsibilities or need predictable hours, ask the unit how it handles them before you apply.
How to prepare
Our practical guidance, based on what the official sources emphasise:
- Get your driving up. Response, and ideally advanced, driving qualifications are a strong start for mobile surveillance.
- Build investigative experience. Surveillance supports investigations; understanding evidence, disclosure and how cases are built helps you at selection.
- Learn the law. RIPA Part 2, the codes of practice and the CPIA come up again and again in covert work.
- Be ready for vetting. Keep your declarations and finances in order; MV looks in detail.
- Ask about attachments. They are the best way to see the work and be seen.
- Be honest with yourself about the lifestyle. Short-notice changes and long hours are part of the job.
Our original practice questions for surveillance boards are in specialist role interview questions and answers.
What we could not verify
- The content and length of the national surveillance course, and its pass rates.
- Force eligibility rules for surveillance posts, such as minimum service or required driving level before applying.
- The full undercover, CHIS handler and covert operations profiles, which sit behind the College Learn login.
- Any change to undercover selection after the public APP was published in 2021, pending the Undercover Policing Inquiry.
Frequently Asked Questions
How do you become a police surveillance officer?
As a serving officer, usually by applying when your force's surveillance unit recruits. A British Transport Police surveillance officer, writing for the College of Policing in 2024, described a robust national process including pre-selection, advanced driver training and a pass or fail course assessed against national standards, after which successful candidates become licensed surveillance operatives. Details and eligibility are set by each force.
Do surveillance officers need advanced driving?
For mobile surveillance, generally yes. The BTP account lists advanced driver training as part of the national process, and the police driving prescribed training regulations include a pre-surveillance motorcycle riding course, valid for two years with a two-day refresher.
How are undercover officers selected?
The College of Policing's public undercover APP says undercover officers volunteer for selection, vetting, training and accreditation. Foundation candidates have a personality assessment with an occupational psychologist; advanced and online-only candidates have a psychological assessment with a chartered clinical psychologist or registered psychiatrist. The College licenses all undercover selection processes and training courses.
How long can you stay an undercover officer?
There is no fixed term. The College's APP says a fixed-term tenure cannot meet the needs of all undercover units and operatives, so officers are assessed under a risk-based tenure policy. Advanced operatives have psychological assessments every six months, and those in very stressful roles every three months.
What is a technical surveillance officer?
The College of Policing's profile says the role provides covert technical surveillance capabilities for operations, including installing, maintaining and extracting technical equipment and producing evidence in line with disclosure law. No previous qualifications are required; in role you complete the technical surveillance unit core skills (D7) course and further courses for your specialism.
What vetting do covert roles need?
Posts with access to sensitive intelligence, informant handlers, and counter terrorism and counter corruption roles are among those the College's vetting guidance lists as needing management vetting (MV). Some counter terrorism roles also need national security vetting, which Counter Terrorism Policing says can take six months or longer.
Who oversees police surveillance?
Directed surveillance and covert human intelligence sources are authorised under Part 2 of the Regulation of Investigatory Powers Act 2000, following Home Office codes of practice. The Investigatory Powers Commissioner's Office oversees the use of covert investigatory powers by more than 600 public authorities, including police forces.
