Ministry of Defence Police vetting rules from May 2026

If you are staring at this statutory instrument on legislation.gov.uk and wondering what actually changes, start here: from 18 May 2026 every Ministry of Defence Police officer must hold and keep the vetting clearance needed for their role. These rules were made on 16 April 2026, laid before Parliament on 22 April 2026, and they apply across England and Wales, Scotland and Northern Ireland. That sounds administrative, but it is not a small tidy-up. The regulations create a full legal process for deciding what happens when the Ministry of Defence Police believes an officer may no longer be suitable to keep that clearance. Because vetting is tied to whether an officer can do the role at all, the stakes are high from the start.

The legislation.gov.uk text says every MDP officer must both hold and maintain vetting clearance, and must promptly tell the vetting authority about any change in personal circumstances, or any other matter, that could reasonably affect their suitability. If an officer stops being an MDP officer, their vetting clearance ends too. The same rules also require records to be kept of vetting applications, decisions, withdrawal assessments and even cases where an officer resigns or retires before the process is finished. The Secretary of State can also require statistical data from those records to be published. **What it means:** this is about traceability. If a decision is later challenged, there should be a clear record of what was known, what was done and when.

A case begins when information comes to the vetting authority suggesting that an officer may no longer be suitable to hold clearance. In most cases the vetting authority is the chief constable. If the officer concerned is the chief constable, that role shifts to the Secretary of State. The regulations also allow the chief constable to delegate some functions, but if suspension or final outcome decisions are delegated, a senior officer must authorise them. One point worth slowing down for is this: vetting is not the same thing as conduct or performance. The statutory instrument makes clear that a vetting matter can still be considered even if the same facts have been looked at under conduct rules, performance rules or external procedures involving bodies in England and Wales, Scotland or Northern Ireland. **What it means:** a person can clear one procedural hurdle and still face another, because the question here is not only what happened, but whether they remain suitable to hold clearance.

The regulations try to balance secrecy and fairness through something called the harm test. Some information can be withheld from the officer if disclosure would risk criminal proceedings, national security, crime detection, misconduct investigations, witness safety or the wider public interest. Material can also be withheld if producing it would take disproportionate effort compared with the seriousness of the case. That is a serious limit, so the rights around it matter. An officer can choose a police friend, can seek help from their staff association and can usually be represented by a lawyer at interviews and appeal meetings. The rules also spell out how notices can be given, including by hand, electronically or by post, and when they count as received. **What it means:** the state is giving itself room to protect sensitive material, but it still has to give the officer enough information to answer the case in a meaningful way.

Before the full assessment is finished, an officer can be suspended, but only with pay. The vetting authority must first consider whether temporary redeployment to different duties or a different location could work instead. Suspension is only allowed if redeployment is not appropriate and if keeping the officer in post could prejudice the assessment, or if the public interest requires suspension. This is not meant to be a one-off decision left hanging in the air. The officer, their police friend or their legal representative can make representations against suspension, and the authority must keep reviewing it. The first review must happen within four weeks if there has not already been one, and further reviews must follow at least every four weeks, or sooner if circumstances change. **What it means:** suspension is possible, but the regulations try to stop it becoming automatic, casual or forgotten.

Once a matter comes in, the first formal step is what the regulations call a vetting severity assessment. The question is simple even if the wording is not: could this matter reasonably lead to vetting clearance being withdrawn? If the answer is no, the case can be referred elsewhere, such as conduct or performance procedures, or no further action can be taken. If the answer is yes, and there is no need to pause because of criminal or other linked proceedings, a withdrawal assessment must begin. That assessment is carried out by an appointed assessor. The assessor must have the right knowledge, skills and experience, must not be an interested party, must not work under the officer concerned and cannot be an MDP member if the case involves a senior officer. That independence test matters. When the possible result is dismissal, the person gathering the facts cannot look like part of a closed internal circle.

The officer should then receive written notice explaining the matter being considered, how it may affect their suitability, the result of the severity assessment, the possible outcomes and the right to get advice. The notice must also explain that the officer has a duty to co-operate and warn that it may harm their case if they fail to mention something they later want to rely on. After that notice, the officer normally has 10 working days to give a written or oral statement and to send documents, including suggestions about lines of enquiry or witnesses. The assessor may also interview the officer, and the officer must attend. If the case is not completed within 15 working days, the assessor must usually provide written progress updates every further 15 working days unless doing so would prejudice the case or another investigation. **What it means:** the rules are trying to combine speed with a basic level of procedural fairness, rather than leaving the officer in the dark for an open-ended period.

There is another safeguard tucked into the middle of the process. If new evidence appears and the assessor believes the case no longer looks serious enough to justify withdrawal, the assessor must tell the vetting authority and explain why. The authority then has to carry out a fresh severity assessment. If the authority agrees that the matter could not reasonably lead to vetting clearance being withdrawn, the withdrawal assessment must stop and the officer must be told that the earlier notice has been withdrawn. That may sound technical, but it matters. **What it means:** once a case has started, it is not supposed to run on autopilot simply because paperwork has been opened.

At the end of the assessment, the assessor sends a written report to the vetting authority. According to the statutory instrument, that report must summarise the evidence, point to relevant documents and give a view on whether clearance should be withdrawn. The final decision then sits with the vetting authority, which can keep clearance in place but impose conditions, downgrade the clearance with or without conditions, or withdraw it. This is the sharpest part of the regulations. If vetting clearance is withdrawn, the officer must be dismissed without notice, and that outcome takes effect from the date it is notified. **What it means:** clearance is not treated as a side issue to the job. For an MDP officer, it is treated as a basic condition of being able to serve.

Officers do get appeal rights, but only on set grounds. They can appeal if the decision was unreasonable, if important new evidence has come to light that could not reasonably have been considered before, or if there was a breach of the regulations or unfairness that could have materially affected the decision. The officer normally has 15 working days to start that appeal. The first appeal goes to a three-person panel. For non-senior officers, the chief constable chairs unless there is a conflict, alongside a lay member appointed by the Secretary of State and a senior officer or equivalent third member. Appeal meetings are held in private, witnesses are only called where necessary in the interests of justice, and the panel can confirm or reverse the decision. If the withdrawal is upheld, the regulations also amend the appeals tribunal rules so the officer can take the case further to a police appeals tribunal. The explanatory note on legislation.gov.uk says no full impact assessment was produced because no significant impact on the private, voluntary or public sector was expected. That may be true in Whitehall terms, but for individual officers these rules are plainly significant. They set out, in much clearer legal detail, when an MDP officer can lose clearance, how that decision should be tested and what due process is meant to look like before a career ends.
