Understand your payslip in plain English

Help me understand my payslip.

Payslip lines: [paste or type each label and amount]
What's changed recently: [new job, hours, student loan, or "nothing"]
What looks wrong to me: [optional]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Each line in plain English.
2. Which lines usually change month to month.
3. What to check if net pay dropped.
4. When to use GOV.UK Check your Income Tax, and when to ask payroll.
5. A short message I can send payroll if something needs checking.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, figures or products. This is help organising my own numbers and wording, not financial advice; point me to MoneyHelper, GOV.UK or Citizens Advice for guidance, and to a free regulated debt adviser if I'm struggling to pay. UK English.
