The published answer: 8 to 10 weeks
In shortHMPPS says pre-employment checks, which include security vetting, take 8 to 10 weeks, but that is an average and not a guarantee.
- Pre-employment checks8 to 10 weeksHMPPS careers site, opened 3 October 2026
- 2018 HMPPS blogAbout 12 weeksDated; updates only after about six weeks
- Whole application6 to 7 monthsAverage, start to first working day
The how-to-apply page says pre-employment checks involve security, identity, past employment and health checks. For Category A or high security prisons, applicants must complete Enhanced Level 2 vetting plus a Counter-Terrorism check. These checks start after you pass the online assessment centre and a vacancy exists.
We could not find a published service level or performance statistic for the time taken by individual vetting decisions for prison officers, and the United Kingdom Security Vetting pages say every application is unique and can take varying amounts of time.
So the honest framing is that most checks conclude in roughly two to two and a half months, some take longer and the policy does not promise a deadline.
Where vetting sits in the 6 to 7 month journey
In shortVetting is a middle stage, not the whole waiting time; you may still be waiting for a post.
The journey begins with an online application of about ten minutes and moves through the scenario-based test, the values-based assessment and the online assessment centre. Only after that do pre-employment checks begin, followed by the medical and fitness assessment, a provisional and then final offer, and training dates.
Some candidates wait at other points: for a vacancy to open at their chosen prison, for a merit list allocation, or for an assessment date. If you are asking 'why is it taking so long', the answer may be that you are still waiting for a post, not that vetting has stalled.

| Stage | Published time | Note |
|---|---|---|
| Online application | About 10 minutes | Reasonable adjustments requested here |
| Scenario-based test | 25 to 40 minutes | Online; practice test available |
| Values-based assessment | Up to 20 minutes | No time limit |
| Online assessment centre | About 2.5 hours | Results within 3 working days |
| Pre-employment checks | 8 to 10 weeks | Security, identity, employment history, health; starts after a pass and a vacancy |
| Medical and fitness | Separate appointment | Travel costs up to £100 |
| Whole journey | 6 to 7 months on average | From application to first working day |
Pass and merit vacancies: when the clock starts
In shortOn a pass vacancy checks start straight away; on a merit vacancy they wait until a post is allocated in score order.
A high scorer on a merit list may start checks quickly, while a lower scorer may wait for places to open. Waiting is not a sign that your vetting has gone wrong, and a place on the list does not mean you have been refused.
You may also apply to several prisons, and your first application scores are reused.
If you are on a merit list, use the wait productively: gather documents, update your address history, resolve anything on your credit file, and prepare for the medical and fitness test. Then respond quickly when contacted, because slow responses are one of the few delays that are in your hands.
Two kinds of vacancy
Pass vacancy
- You are matched to the next available post.
- Checks start straight away.
- Your pass is valid for 12 months.
Merit vacancy
- Posts are allocated in order of your assessment score.
- Checks only begin once you have been allocated a post.
- The merit list is valid for 12 months. The October 2026 advert for HMP Birmingham is a merit vacancy.
What the vetting process involves, step by step
In shortThe most common avoidable delay is a form that goes back and forth, so complete every section the first time.
The vetting policy describes the mechanics. Where a questionnaire is incomplete or documents are inadequate, the VCP must return it to you, request the missing information and chase outstanding documents.
Complete every section, attach every document asked for, and use the same names and dates as on your application.
If the checks throw up something requiring judgement, the case can go to the Approvals and Compliance team, which adds time. That is not a bad sign in itself, since the team exists to make balanced decisions where an individual has something to explain.
The best way to shorten this stage is a clear, truthful explanation in your original submission.
- You complete the pre-employment questionnaires and provide identity documents.
- The Vetting Contact Point checks them and verifies your identity face to face, and clarifies right to work.
- When satisfied, the VCP submits a clearance request to Shared Services Connected Limited, which sends an encrypted link for the vetting questionnaires.
- The completed questionnaire and verified ID documents go back to SSCL, which carries out the checks and confirms that a candidate has passed or been declined.
- If anything is missing, the form comes back to you to complete.
- If judgement is needed, the Approvals and Compliance team reviews it.
- You are told the outcome, and the recruitment team moves on to the medical, fitness test and offer.
Things that can slow vetting down
In shortIncomplete forms, employment gaps, time abroad, cases needing judgement and a late CTC questionnaire all add time.
Based on the policy, an incomplete questionnaire or missing identity document goes back to you. The Counter-Terrorist Check adds its own steps, including the Security Questionnaire and records checks, and a possible interview if there are unresolved concerns.
Those steps involve other agencies, and United Kingdom Security Vetting itself says delays outside its control can occur.
| Cause | Source | What helps |
|---|---|---|
| Incomplete questionnaire or documents | PSI Annex B (VCP duties) | Complete every section; send every document |
| Gaps, self-employment or many recent employers | PSI vetting checklist annex | Write out a full timeline with references |
| Time abroad; 3-year residency for Category A | Careers site; PSI 4.10 | Gather evidence; tell the recruitment team early |
| Record, insolvency or association needing judgement | PSI Annex B (Approvals and Compliance team) | Declare it and explain it clearly |
| Late Security Questionnaire for CTC | PSI paragraph 4.9 | Complete within 15 working days |
How to avoid avoidable delay
In shortPrepare before you are asked, answer quickly, and never leave out something awkward.
Fewer follow-up queries mean faster clearance. The policy says non-disclosure of offences is likely to mean refusal with no leave to reapply for 12 months, which is a far longer delay than any administrative wait. Our vetting guide explains what to declare.
What to do
- Before applying, gather proof of address and identity, a full address and employment history, names and contact details of referees and a list of anything you must declare.
- If you have a counter-signatory in mind for the personal reference, tell them to expect a request.
- Answer every request quickly and keep a log: what was asked, when and what you sent.
- Check your email, including spam folders, because the questionnaire link and chasers are sent electronically.
- If you change address, phone number or email address during the process, tell the recruitment team in writing.
- Do not try to speed things up by leaving out something awkward.
What to do if you are still waiting
In shortCheck where you actually are first; a quiet fortnight inside the 8 to 10 week window is normal.
Look at your invitation, the email trail and the vacancy type. If you passed the assessment centre on a merit vacancy, you may be waiting for allocation and not for vetting. If your questionnaire is submitted, the published window is 8 to 10 weeks.
If you are well past ten weeks, contact the recruitment team using the details on your correspondence or on the careers site. The careers site publishes 0345 241 5358 and moj-recruitment-vetting-enquiries@resourcing.soprasteria.co.uk for recruitment and vetting enquiries on its reasonable adjustments page.
- Check your invitation, email trail and vacancy type.
- If your questionnaire is submitted, allow the published 8 to 10 weeks.
- If you are well past ten weeks, contact the recruitment team. Keep your message short: your name, the vacancy reference, the date you submitted your questionnaire and a polite request for an update.
Returning, transferring and renewals: other timings
In shortPeople who already hold clearance follow different rules, including a 10-year Enhanced Level 2 life and a new check after 12 months out of the Civil Service.
Existing national security vetting can be accepted and transferred from another government department if it is still in date and the former department confirms that baseline checks were completed.
An abridged Enhanced Level 2 application is still needed to register you on the HMPPS system, which the policy says has a short turnaround once the form is correct.
If you are a former officer thinking about the Returners' Scheme, which the careers site says covers people who left as a prison officer within the last five years, ask the recruitment team how your previous clearance is treated. The policy gives general rules but not an applicant-specific answer.
- Out of the Civil Service for more than 12 months: a new Enhanced Check must be started.
- Out of the UK for more than six months during an absence from work: renewal of vetting is required.
- Enhanced Level 2 lasts ten years for directly employed staff, and three months before expiry the establishment and the individual are notified to complete the renewal form.
What we cannot tell you
In shortWe cannot say how long your case will take or whether it will produce a refusal; no pass rate or timing distribution is published.
- HMPPS applications722,2391 July 2024 to 30 June 2026; all HMPPS roles combined; no prison officer vetting pass rate
- Formal offers accepted23,570Recruitment diversity statistics, all HMPPS roles
No official data on the distribution of vetting times for prison officers is published, and anything claiming otherwise, such as a forum poster saying 'mine took five weeks', is a single anecdote. The published 8 to 10 weeks is HMPPS's own average description.

Frequently asked questions
How long does prison officer vetting take?
HMPPS says pre-employment checks, which include security vetting, take 8 to 10 weeks. A 2018 HMPPS blog said about 12 weeks, which is out of date. The whole application averages 6 to 7 months. No individual service level is published, so treat 8 to 10 weeks as an average.
When does prison officer vetting start?
After you pass the online assessment centre and a vacancy is available. On a pass vacancy checks begin immediately. On a merit vacancy they begin once a post is allocated to you in order of assessment score. Merit and pass lists are valid for 12 months.
Why is my vetting taking longer than 10 weeks?
Possible reasons include an incomplete questionnaire, gaps or many recent employers needing extra references, time abroad, a record or insolvency entry needing judgement, or the extra Counter-Terrorist Check steps for high security prisons. Contact the recruitment team with your submission date and ask for an update.
What is the 15 working day deadline in vetting?
For national security vetting such as the Counter-Terrorist Check, the vetting policy says you get an encrypted link to an online Security Questionnaire. If it is not completed within 15 working days the application is closed down and a new form is needed to restart it.
Can I start work before vetting is complete?
The published process is that the provisional offer is conditional on checks, then a final offer follows, and training dates are agreed. We found no published route to start before clearance, and the policy says non-vetted individuals must not work for HMPPS without a risk management plan. Ask the recruitment team.
Does vetting take longer for high security prisons?
It involves more: Enhanced Level 2 plus the Counter-Terrorist Check, with a Security Questionnaire, Security Service records check and possible interview. No separate published timeframe for CTC could be found on the pages we read, and the three-year UK residency rule must be met.
How long does vetting last once cleared?
Enhanced Level 2 expires after 10 years for directly employed staff. Counter-Terrorist Check also lasts 10 years, or 7 for people under 21 when issued. You must report changes in circumstances during that time.
