Civil Nuclear Constabulary
Recruitment Process
The CNC is an armed force protecting civil nuclear sites. Its constables are Authorised Firearms Officers from the start, which shapes everything: a weapons handling assessment, a bleep test to level 7.6, a stricter medical and residential firearms training. Written from the CNC's own careers pages, read on 23 October 2026.
Independent information, not advice · Sources checked 23 October 2026 · England and Wales unless stated
Apply for a police constable Authorised Firearms Officer vacancy. After shortlisting you sit the College of Policing's National Sift and online assessment centre, then a CNC recruitment day with a firearms briefing, a weapons handling assessment and a values based interview. You must pass an AFO medical, a bleep test to level 7.6, references and security vetting, then complete a 19-week residential foundation programme including firearms training.
The role: an armed officer from day one
The Civil Nuclear Constabulary protects civil nuclear sites and nuclear material. Under section 56 of the Energy Act 2004, its constables have police powers at and within 5km of licensed nuclear sites, at places where nuclear material is held or in transit and, since the Energy Act 2023, where it provides additional police services in the interests of national security, with cross-border arrest powers in England, Wales and Scotland. Since 1 April 2025 it has also protected four gas sites: Garlogie, St Fergus, Easington and Bacton.
The CNC says every new officer joins as an Authorised Firearms Officer (AFO). There is no unarmed constable role to start in and no PCDA, DHEP or PCEP. In England officers follow the Level 4 Non-Home Office Police Officer Apprenticeship, delivered by the CNC, with an End Point Assessment by Skills for Justice; officers in Scotland follow the same programme without the formal apprenticeship. See CNC training and the EPA.
Named sites on the CNC's pages include Sellafield, Dungeness, Dounreay, Sizewell and Torness and the current vacancies add Garlogie and St Fergus in Aberdeenshire. The CNC lists sites in both England and Scotland on its locations page.
Is the CNC recruiting now?
On 23 October 2026 the CNC's vacancy portal listed police constable AFO roles, none with a closing date shown:
- Dounreay (Caithness): standard, relocation, transferee and transferee relocation listings.
- Garlogie and St Fergus (Aberdeenshire): standard and transferee listings. Both new recruit listings include a £5,000 a year non-consolidated location allowance.
- National Firearms Instructor roles at Dounreay and FTU North (Griffin Park, Cumbria) for serving or recent instructors, closing 16 November 2026 at 23:59.
No new recruit advert for an English site was open, although the CNC announced rolling Sellafield recruitment on 3 March 2026 and its accounts say it has reached establishment at several sites. English applicants can set a job alert on the portal. Vacancies come and go by site: see CNC jobs by site. A listing without a closing date can still close without notice.
CNC eligibility
- Age: 18 or over to apply and at least 18 years and 6 months before starting. No upper age limit.
- Residency and vetting: you must pass police vetting and National Security Vetting. The CNC normally expects up to 10 years' UK residence depending on the vetting level; shorter residence can be considered with extra checks, but clearance is not guaranteed. The CNC publishes no sole-British rule like the MOD Police's: it checks nationality and right to work against national eligibility criteria. See overseas travel and residency in vetting.
- Driving licence: a full manual UK or European licence with no more than six points.
- Qualifications: none required. Functional skills English and maths are funded during training if needed.
- Criminal record: a clean record is preferred, but some minor offences may not exclude you. Disclose everything, including cautions, fixed penalties, NFA outcomes and juvenile matters.
- Finances: debts must be manageable; a mortgage, student loan or credit card you can manage is fine.
- Business interests: call CNC recruitment (0330 3135 401) if you run or work in another business, or if a relative holds a licence for alcohol, betting, gaming or entertainment.
- Membership: current or past members of the BNP or similar organisations are not accepted.
- Tattoos and piercings: face, throat or front-of-neck tattoos are assessed case by case and may be incompatible; declare all tattoos with photos of visible ones; visible stretched piercings are not allowed.
The CNC recruitment stages in order
| Step | Stage | What happens |
|---|---|---|
| 1 | Online application form | Eligibility questions covering family, tattoos, business interests, finances, convictions and police contact. |
| 2 | Shortlisting | Against national recruitment criteria; outcome normally within 5 to 10 working days. |
| 3 | College of Policing National Sift | Situational judgement test and behavioural questionnaire. You must pass to continue. |
| 4 | College of Policing online assessment centre | Competency-based interview, written exercise and briefing exercise. |
| 5 | CNC Recruitment Day | Morning or afternoon session: CNC insights presentation, firearms briefing and weapons handling assessment and a CNC values based interview. |
| 6 | Pre-employment assessments | GP medical declaration, optician's form, occupational health medical and the bleep test to level 7.6 (may be held at any point). |
| 7 | Conditional offer and checks | References for the last three years, military and police service checks and security vetting (each can take up to three months). |
| 8 | Initial Foundation Programme | 19 weeks residential, including firearms training; fingerprints for elimination in week one. |
The CNC's gov.uk recruitment page says the whole process takes five to eight months from application to being in post.
The National Sift and online assessment centre
Unlike BTP, MOD Police and the PSNI, the CNC uses the College of Policing's national online assessments, the same ones used by the 43 forces in England and Wales:
- National Sift: a situational judgement test and a behavioural questionnaire. You must pass to continue.
- Online assessment centre: a competency-based interview, a written exercise and a briefing exercise, assessed against the College's Competency and Values Framework.
That means our England and Wales guides apply directly at this stage. Start with the National Sift explained, how the sift is scored and the online assessment centre hub, including the written exercise and briefing exercise guides.
The CNC recruitment day
If you pass the online assessments you are invited to a recruitment day (a morning or afternoon session) and occupational health contacts you to start the pre-employment checks. The day includes:
- A CNC insights presentation about the force and the role.
- A firearms briefing and weapons handling assessment. The CNC says it tests your dexterity and your ability to follow instructions while handling a firearm.
- A CNC values based interview.
The CNC's transferee page says its Values Based Interview assesses suitability against the Competency and Values Framework and the AFO role profile, the Code of Ethics, policing principles and respect for race and diversity; the new recruit page gives less detail. The CNC does not publish the questions, length or scoring. See our values interview guide and Recruitment Day guide. Expect to be asked why you want an armed role protecting nuclear sites and to show you understand what that involves: long, often uneventful shifts in which you must stay alert, strict procedures and a duty to use force only when it is justified. This is our reading of the role, not CNC guidance.
You do not need firearms experience. The CNC describes the assessment as testing dexterity and following instructions. Listen to the safety briefing closely, do exactly what you are told in the order you are told and ask if anything is unclear. Being careful and precise matters more than speed.

The CNC fitness test: level 7.6
The CNC's minimum is level 7.6 on the multi-stage fitness test, reassessed every year. It is part of the pre-employment medical, which the CNC says may be held at any point in the process, so start training before you apply. See our plan from 5.4 to 7.6.
Level 7.6 is a big step up from the 5.4 used for most constable recruitment. The CNC's pages do not say whether its test runs over 15 or 20 metres, so ask the CNC which track and audio it uses before you train. Our bleep test levels explained and specialist role fitness standards pages explain what higher levels involve. To see where you are now, time yourself on the free 15m bleep test simulator and convert levels between tracks with the bleep test level converter.
The AFO medical: stricter than a Home Office force
The CNC applies Authorised Firearms Officer medical standards, which it says are different from those of Home Office forces and Police Scotland; in practice they are stricter on eyesight and hearing. Full detail and a free self-check: CNC medical and eyesight standards. Read its pre-employment medical guidance before you apply. You provide a GP medical declaration and an optician's form, then attend an occupational health medical of up to about an hour and a half, which includes spirometry, a hearing test and a urine glucose test.
| Area | CNC rule |
|---|---|
| Eyesight aids | Glasses cannot be used to meet the standard; contact lenses can. If soft lenses give successful correction, the unaided 6/36 rule may not apply |
| Distance vision (corrected) | 6/12 in either eye and 6/6 with both eyes |
| Unaided vision | At least 6/36, unless corrected with soft lenses |
| After eye surgery | Six weeks after surgery if the cornea is not significantly weakened; some procedures (for example photorefractive keratotomy) are likely to affect suitability |
| Hearing aids | Not compatible with the AFO role |
| BMI | 18.5 to 30; above 30, body fat no more than 25% (men) or 32% (women); appointment deferred until within limits |
| Diabetes on medication | Normally incompatible |
For how the recruitment medical works in Home Office forces, see our police medical guide. If you wear glasses or a hearing aid, check the CNC guidance carefully before applying.
Conditional offer, references and vetting
After you accept a conditional offer, the CNC takes references covering the last three years of your employment and runs military and police service checks where they apply (up to three months). Security vetting follows, which the CNC calls the most time-consuming stage, taking up to three months. In week one of training your fingerprints are taken, used only for crime scene elimination.
Training: the 19-week Initial Foundation Programme
- Length and format: 19 weeks, residential, starting with a one-week induction in Oxfordshire, then training at a delivery centre in Oxfordshire, Cumbria or Caithness (the application process page lists Oxfordshire, Surrey or Cumbria). All accommodation, travel, food and refreshments are provided, including eight return journeys in hire cars.
- Firearms: trained to the National Police Firearms Training Curriculum; you must qualify with each CNC weapon system.
- Pay: full starting salary from day one.
- After the IFP: about 20 months as an operational AFO building a portfolio, ending in an End Point Assessment, after which you are confirmed as a constable (in England; Scotland follows the same programme without the formal apprenticeship).
- Probation: two years. Specialist roles (such as firearms instructor, Strategic Escort Group, dog handler or police medic) come after probation.
The gov.uk recruitment page gives an older 17-week figure; the CNC's own careers pages say 19 weeks.

How to prepare for CNC recruitment
General PolicePay advice, not endorsed by the CNC and no guarantee of any result.
- Check the medical first. Eyesight (glasses cannot be used to meet the standard), hearing (no aids) and BMI rules rule people out late in the process. Read the CNC's guidance before you apply.
- Start fitness training now. Level 7.6 needs a real base of running fitness. Train beyond it, because it is retested every year.
- Prepare for the National Sift and OAC exactly as you would for a Home Office force: the same College tests.
- Think through the armed role. Why you want it, how you would cope with long static shifts and what lawful, proportionate use of force means to you.
- Prepare for vetting. Gather your address history, declare everything and check your finances and business interests against the CNC's rules.
- Plan for residential training and a posting that may be remote, such as Caithness or Aberdeenshire.
What we could not verify
- The bleep test track length (15m or 20m) and number of attempts allowed.
- The format of the CNC Values Based Interview and its questions (see our values interview guide).
- The vetting level beyond "police and National Security Vetting".
- Any psychological or firearms aptitude test beyond the weapons handling assessment. The pages we read do not describe one.
- The drug test method. The CNC does run pre-employment drug tests (375 in 2019/20, FOI 2021) but does not publish the method.
- Closing dates for the current vacancies.
Frequently Asked Questions
How do I join the Civil Nuclear Constabulary?
Apply through the CNC's vacancies when a police constable Authorised Firearms Officer role is advertised. After shortlisting you sit the College of Policing's National Sift and online assessment centre, then attend a CNC recruitment day with a weapons handling assessment and values based interview. Pre-employment checks include an AFO medical, the bleep test to level 7.6, references and security vetting, followed by 19 weeks of residential training.
Does the CNC use the National Sift and OAC?
Yes. The CNC's application process page says candidates sit the College of Policing's National Sift (a situational judgement test and a behavioural questionnaire) and then the online assessment centre (a competency-based interview, written exercise and briefing exercise) before the CNC's own recruitment day.
What is the CNC fitness test?
A multi-stage fitness test (bleep test) to a minimum of level 7.6, which the CNC reassesses every year. That is well above the level 5.4 used for constable recruitment in England and Wales. It may be held at any point in the recruitment process, as part of the medical, so start training before you apply.
Are all CNC officers armed?
Yes. The CNC says every new officer joins as an Authorised Firearms Officer and must qualify on each CNC weapon system during the 19-week Initial Foundation Programme.
What is the CNC weapons handling assessment?
Part of the CNC recruitment day. After a firearms briefing, you are assessed on handling a firearm: the CNC says it tests your dexterity and your ability to follow instructions. No firearms experience is required to apply.
Can you wear glasses in the CNC?
Not to meet the eyesight standard. The CNC's pre-employment medical guidance (version 8) says glasses are not acceptable to meet the standard, so contact lenses are the route for anyone who needs correction. The unaided 6/36 rule may not apply where soft lenses give successful correction. Hearing aids are not compatible with the AFO role.
How much does a CNC officer earn?
The CNC's 2026/27 pay gives probationers £32,256, held for the whole two-year probation, then £33,609, with a chance of the next point each year up to £52,014 at point 7 within seven years. The new recruit adverts for Garlogie and St Fergus add a £5,000 a year location allowance. Officers pay 8.2% into the UKAEA pension scheme. You are paid in full from day one of training.
How long does CNC recruitment take?
The CNC's gov.uk recruitment page says five to eight months from application to being in post. References and service checks and security vetting can each take up to three months.
What is the age limit for the CNC?
You must be 18 or over to apply and at least 18 years and 6 months before you start. There is no upper age limit.
Do I need qualifications to join the CNC?
No. The CNC says no qualifications are required and training includes funded functional skills support in English and maths if you need it.
