Everyone makes mistakes at work. It happens to experienced workers too. The important thing is not the mistake itself — it is how you explain it.
If you can explain clearly and professionally, your manager will respect you more. If you stay silent or make excuses, the problem often gets worse.
This guide will help you handle the moment with confidence. You’ll learn exactly what to say when something goes wrong at work.
AI Quick Answer
When you make a mistake at work, tell your manager as soon as you know. Use the AWARE formula: Acknowledge the mistake, explain What happened, Apologise, give the Reason (briefly), and explain what you’ll do differently next time. For example: “I made a mistake with the order — I picked the wrong quantity because I misread the label. I’m sorry and I’ve already told the team. Next time I’ll double-check before sealing the box.” This approach builds trust and shows you’re professional.
This guide teaches you the AWARE Formula — a proven structure for explaining mistakes at work with confidence. Learn it once, use it everywhere.

Why Explaining a Mistake Well Matters
In UK workplaces, managers expect workers to:
- Take responsibility for their mistakes
- Explain what happened clearly
- Show they understand the problem
- Tell them what they will do next time
You do not need perfect English to do this. You need the right phrases. Building confidence through clear communication is what this guide teaches you.
Useful Phrases for Explaining a Mistake
Step 1 — Acknowledge the Mistake
“I need to let you know that I made a mistake.”
“I want to be honest with you — something went wrong.”
“I think I made an error and I’d like to explain.”
Step 2 — Explain What Happened
“This morning I packed the wrong boxes because the labels were very similar and I misread them.”
“I was not sure about the procedure and I should have asked.”
Step 3 — Apologise Professionally
“I’m sorry for the mistake and for any problems it caused.”
“I apologise — I should have been more careful.”
Step 4 — Explain What You’ll Do Differently
“In future, I will double-check before I submit.”
“I have already corrected the error and informed the team.”
Step-by-Step: How to Explain a Mistake
Step 1 — Acknowledge the Mistake
The first thing you should do is acknowledge the mistake. This means you accept that something went wrong. Do not wait for your manager to come to you. If you made a mistake, go to them first. This shows you are honest and professional. See how to explain a problem at work — early communication is always better.
Step 2 — Explain What Happened
After you acknowledge the mistake, explain what happened. Keep it simple and factual. Do not blame other people. Do not make excuses. Just explain the facts using simple structure: What happened + When it happened + Why it happened.
Step 3 — Apologise Professionally
A professional apology is short, sincere, and focused on the impact — not just your feelings. For more apology phrases, see how to apologise at work professionally.
Step 4 — Explain What You Will Do Differently
This is the most important part for your manager. They want to know the problem will not happen again. Tell them: “In future, I will…” or “I have already…”
🎬 Real Workplace Scenario
Situation: A warehouse worker picked the wrong quantity for a Tesco order — 20 boxes instead of 30.
The worker talks to their supervisor Sarah:
“Hi Sarah, have you got a minute? I need to let you know I made a mistake with the Tesco order this morning. I picked 20 boxes instead of 30. I misread the pick sheet because the font was very small. I’m sorry for the error and I know it caused a delay. I’ve already told the despatch team and they’re sorting it. In future, I’ll double-check the quantity before I seal the box.”
Sarah’s response:
“Thank you for telling me. These things happen. Let’s make sure it doesn’t happen again.”
✅ The worker explained what, why, sorry, and what next — all in a few sentences. This is exactly how it should be done.
✅ Explain a Mistake Checklist
Before you talk to your manager, check:
- ☐ Did I tell them quickly (before they found out)?
- ☐ Did I acknowledge the mistake clearly?
- ☐ Did I explain what happened (briefly)?
- ☐ Did I apologise professionally?
- ☐ Did I say why it happened (short reason)?
- ☐ Did I explain what I’ll do differently next time?
- ☐ Did I mention what I’ve already done to fix it?
⚠️ Common Mistakes to Avoid
❌ Wrong: “It wasn’t my fault.”
✅ Better: “I understand what went wrong and I’ll make sure it doesn’t happen again.”
Even if it is partly true, this sounds defensive.
❌ Wrong: “Nobody told me.”
✅ Better: “I wasn’t sure about the procedure — I should have asked first.”
This sounds like you are blaming others.
❌ Wrong: “It’s not a big deal.”
✅ Better: “I understand this caused a problem and I’m sorry.”
Your manager decides if it is a big deal.
❌ Wrong: Over-apologising many times: “I’m so sorry, I feel terrible, I’m so sorry again…”
✅ Better: Apologise once sincerely, then focus on the solution.
This can make you seem unprofessional in UK workplaces.

Frequently Asked Questions
What if the mistake was partly someone else’s fault?
Focus on your part first. After you have explained your responsibility, you can say: “I think there may also have been a misunderstanding with the instructions — would it be helpful to review the process together?”
Do I have to tell my manager about every small mistake?
It depends on the workplace. For small errors that you fix immediately, you may just need to correct them. For anything that affects customers, safety, stock, or other team members, always tell your manager. When in doubt, tell them.
What if English is very hard for me in that moment?
Try using our Explain Generator tool. Type what happened in simple notes (in any language if easier), and it will help you write a clear, professional explanation in English.
What if my manager gets angry?
Stay calm. Use phrases like: “I understand you’re frustrated. I take full responsibility.” or “I’m not going to make excuses. I’m sorry and I want to fix this.” Do not argue. Do not raise your voice. For more guidance, see how to deal with difficult conversations at work.
Can I send a written message instead of speaking face to face?
For serious mistakes, speaking in person is better. For smaller issues, a message is often fine. Try our Message Rewriter tool to help you write a professional message.
