If required, you must also be able to:
- Be “on-call” throughout the day and night for 1 week out of every 4

Candidates are asked to provide 1 location preference only. Please ensure that you only apply for a location that you are willing and able to work from, as we will only make one offer of employment.

Training
Training Requirement
A comprehensive training programme is provided.
The course is 4 weeks in total with an additional one-week personal safety training. There is a guided learning module to complete prior to the event, 3 weeks training, 1 week safety and then a 1-week final exercise. The course is residential and cannot be done from home.
This training event will build on previous experience in the Law Enforcement arena and provide a refresh and upskilling in HMRC powers and procedures.
For those that have not previously had the power to carry out an arrest under the Police and Criminal Evidence Act 1984, you will be trained to use this power before attending the Final Exercise.
Successful completion of the training course is an essential condition for continuing in the appointed role. Candidates must demonstrate the necessary competencies and meet the assessment standards set out during the training period. If a candidate is unable to successfully complete the training, HMRC may explore suitable alternatives including completing HMRC’s full Criminal Investigation Foundation Training programme, which is 9 weeks and a mixture of digital and face to face events. You would need to be available for the full programme.
Public and Personal Safety Training (PPST) is a crucial element of becoming a criminal investigator. This is a PASS/FAIL event.
The event includes digital and face-to-face training where you will learn practical techniques to ensure your safety and that of your colleagues, as well as how to apprehend and physically restrain suspects and apply handcuffs.
The event is mainly physical and includes scenario-based exercises where you will require an appropriate level of fitness and mobility such as being able to carry equipment up and down stairs and get up and down from the floor unaided.
All officers undertaking this training must obtain a valid occupational health certificate (acquired from HMRC’s healthcare provider) stating they are fit to undertake regular physical training. Once this training is complete, you will have a one-day refresher training event at least every six months after this to ensure you are able to carry out operational duties.
An annual Job Related Ability Test is being introduced for all participants of PPST which is also a Pass/Fail event.
Failure to meet the required standards for the programme will result in appointment to this role being brought to an end and consideration of redeployment into an alternative role. This can result in the removal of the Flexibility Payment (FP) paid in respect of the Criminal Investigator role. Where it is not possible to redeploy the candidate into an alternative role, the candidate may be assigned to the HMRC Redeployment Register.
Candidates appointed on promotion who do not successfully complete the training will revert back to their previous substantive grade and the respective HMRC pay scale for this grade. Where FP is removed, jobholders will not be entitled to a Period of Adjustment (POA), but they will receive 2 months’ notice in writing of the cessation of the allowance.
Additional Security Information
Security Check (SC) Clearance is mandatory for this role. Successful candidate will need to hold or need to obtain Security Check (SC) Clearance through UKSV.

Where this applies, you can apply but will need to declare that you require a reasonable adjustment at the point you receive a provisional offer. The vacancy holder will then discuss your specific requirements to consider if this can be reasonably accommodated in this role.
Further Location Information
