Disciplinary Procedure Steps UK
A step-by-step guide to running a fair disciplinary procedure in the UK. Follow these steps to stay ACAS-compliant and reduce your tribunal risk.
Following a proper disciplinary procedure isn't just good practice - it's essential for defending any subsequent tribunal claim. Here's a step-by-step guide that follows the ACAS Code of Practice.
Step 1: Identify the Issue
Before starting any formal process, be clear about:
- What the specific allegation or concern is
- Whether it's misconduct, poor performance, or something else
- Whether it's potentially gross misconduct
Tip: Document everything from the start. Your notes may be needed as evidence later.
Step 2: Investigate
What Investigation Involves
- Gather documentary evidence (emails, records, CCTV)
- Interview witnesses
- Give the employee an opportunity to respond informally
- Document your findings
Investigation Meetings
An investigation meeting is not a disciplinary meeting. You should:
- Explain you're gathering facts, not making decisions
- Tell them they can be accompanied (though there's no statutory right at investigation stage)
- Keep an open mind
- Take detailed notes
Suspension (If Necessary)
You may need to suspend the employee during investigation if:
- Evidence might be tampered with
- Witnesses might be pressured
- There's a risk to other employees or the business
Suspension should be:
- On full pay
- As brief as possible
- Kept under regular review
- Not treated as a punishment
Step 3: Decide Whether to Proceed
After investigation, decide:
- Is there a case to answer?
- If yes, is it misconduct, gross misconduct, or performance?
- What's the appropriate level of meeting?
Step 4: Invite to Disciplinary Meeting
Write to the employee with:
- The specific allegations - Be detailed enough for them to respond
- The evidence - Include copies of relevant documents
- The potential outcomes - Including dismissal if applicable
- Meeting date, time and location
- Right to be accompanied
- Reasonable notice - Usually at least 48 hours
Step 5: Hold the Disciplinary Meeting
Before the Meeting
- Arrange a private room
- Ensure the decision-maker hasn't been involved in the investigation (if possible)
- Have a note-taker present
- Have all evidence to hand
During the Meeting
- Explain the purpose and allegations
- Present the evidence against them
- Allow them to respond fully
- Ask questions to clarify points
- Let their companion participate appropriately
- Adjourn if needed to consider new information
- Don't make a decision in the meeting - adjourn to consider
The Companion's Role
The companion (colleague or union rep) can:
- Put the employee's case
- Summarise the key points
- Confer with the employee
They cannot:
- Answer questions for the employee
- Prevent the employer asking questions
Step 6: Make Your Decision
Consider:
- The evidence presented
- The employee's responses
- Their length of service
- Their disciplinary record
- How similar cases have been handled
- Whether dismissal is reasonable (for dismissal cases)
Possible Outcomes
| Level | When Used | Duration |
|---|---|---|
| No action | Allegations not proven | N/A |
| Verbal warning | Minor misconduct, first offence | 6 months typical |
| Written warning | More serious, or after verbal | 12 months typical |
| Final written warning | Serious, or after written | 12-24 months typical |
| Dismissal | Gross misconduct, or final warning in place | N/A |
Step 7: Communicate the Decision
Write to the employee with:
- The decision and reasons
- Any sanction imposed and its duration
- What improvement is expected (if applicable)
- The right to appeal
- How to appeal and the deadline
Step 8: Handle the Appeal
If the employee appeals:
- Acknowledge receipt promptly
- Arrange an appeal hearing
- Use a more senior manager who wasn't involved
- Consider the grounds of appeal
- The appeal can uphold, overturn, or vary the original decision
Common Disciplinary Procedure Mistakes
- Pre-judging the outcome - Keep an open mind throughout
- Inadequate investigation - Don't rush this step
- Not giving enough detail - The employee must know the case against them
- Refusing a companion - It's a statutory right at disciplinary meetings
- No right of appeal - This is essential under the ACAS Code
- Inconsistent treatment - Similar cases must be treated similarly
- Taking too long - Deal with matters promptly

Frequently Asked Questions
- How long should a disciplinary procedure take?
- There's no set timeframe, but matters should be dealt with without unreasonable delay. A straightforward case might be resolved within 2-4 weeks, while complex investigations may take longer.
- Can I dismiss someone at a first disciplinary hearing?
- Yes, but only for gross misconduct. For ordinary misconduct, you should follow a progressive discipline approach: verbal warning, written warning, final written warning, then dismissal.
- What if the employee won't attend the disciplinary meeting?
- You should try to rearrange once. If they still won't attend without good reason, you can proceed in their absence, but you should still consider any written submissions they make.
