Experiencing underpayment can be frustrating and financially destabilizing. It undermines your trust in your employer and can have far-reaching consequences for your personal and professional life.
Thankfully, the UK has robust legal protections for employees to ensure fair pay and rectify situations where wages are withheld or underpaid.
This comprehensive guide explores your rights, common causes of underpayment, steps to resolve it, and what to do if the issue escalates. Additionally, we’ll discuss ways to prevent underpayment and how to handle workplace retaliation if it occurs.
Understanding Your Rights
Employees in the UK are protected under several key pieces of legislation that guarantee fair pay and timely compensation. Two essential laws in this regard are:
1. The Employment Rights Act 1996
This act mandates that employers pay their employees in full and on the agreed payday, as specified in their employment contract. It also sets out employees’ rights to receive a written statement of employment terms, including details about pay and working hours.
2. The National Minimum Wage Act 1998
All workers are entitled to a minimum wage, which varies based on age and employment type (e.g., apprenticeships). Failing to pay the correct minimum wage constitutes a breach of the law.
Beyond these, other regulations cover holiday pay, sick pay, and maternity pay, ensuring employees are fairly compensated in all circumstances.
What are the Legal Deductions from Wages?

Employers can make deductions from wages, but these must be legally justified. Some examples of permissible deductions include:
- Statutory Deductions: Income tax and National Insurance contributions are standard deductions that must be paid to HM Revenue & Customs.
- Contractual Deductions: If your employment contract specifies deductions (e.g., for pension contributions or equipment), these are generally lawful.
- Court-Ordered Deductions: Payments for court-ordered fines or child maintenance obligations are also permitted.
Unlawful deductions include penalties for minor mistakes, arbitrary reductions, or withholding pay without clear contractual or statutory reasons. If you believe your deductions are unlawful, it’s essential to challenge them.
What are the Common Causes of Underpayment?

Underpayment can arise from various issues, including unintentional administrative errors and deliberate employer practices. Some common causes include:
1. Administrative Errors
Payroll mistakes are among the most common reasons for underpayment. These errors can occur due to incorrect data entry, software malfunctions, or miscommunication between departments. For example, your employer may fail to record your overtime hours or apply the wrong tax code.
2. Misclassification of Workers
Employers sometimes misclassify workers as independent contractors or apprentices when they should be treated as employees. This misclassification can result in lower pay or the absence of benefits such as holiday pay or sick pay.
3. Unpaid Benefits
Holiday pay, sick pay, and bonuses are often overlooked or improperly calculated. For instance, you may not receive the correct holiday pay entitlement based on your average weekly earnings, or your employer might fail to include commission or overtime payments in calculations.
4. Illegal Deductions
Some employers may unlawfully deduct wages for breakages, uniform costs, or even as punitive measures for lateness or mistakes. Without clear contractual agreement or legal justification, such deductions are illegal.
Understanding the root cause of underpayment is crucial to addressing it effectively.
What are the Steps to Take If You’ve Been Underpaid?

If you believe you’ve been underpaid, it’s essential to act promptly and methodically. Here’s a detailed guide to resolving the issue:
1. Verify the Underpayment
Start by reviewing your payslip, employment contract, and any timesheets or other records you’ve kept. Check for discrepancies in:
- Hours Worked: Compare your timesheets to the hours recorded in payroll.
- Overtime or Bonuses: Ensure any additional payments you’re entitled to have been included.
- Holiday Pay or Benefits: Confirm these are calculated correctly based on your average earnings.
If your employer hasn’t provided you with a payslip, you can legally request one. It’s a legal requirement for employers to issue payslips to their employees.
2. Communicate with Your Employer
Many underpayment issues can be resolved through open communication. Speak to your manager, HR department, or payroll team to raise your concerns informally. Present your evidence and explain why you believe you’ve been underpaid.
Often, employers will correct genuine errors without further escalation. However, if this doesn’t resolve the issue, move to the next step.
3. Document the Issue
If informal discussions don’t work, put your concerns in writing. Include the following details in your letter or email:
- Dates: Clearly specify the pay periods affected.
- Amount Owed: Provide a breakdown of the missing amount.
- Supporting Evidence: Attach timesheets, contracts, and previous payslips as proof.
Keep copies of all correspondence for your records. This documentation will be invaluable if the dispute escalates.
4. Raise a Formal Grievance
If the issue remains unresolved, follow your employer’s formal grievance procedure. Most companies have a policy in place that outlines how employees can raise complaints.
Submit a written grievance, attend any scheduled meetings, and provide all necessary evidence. Employers are required to respond to grievances within a reasonable time and provide a written outcome.
5. Seek External Assistance
If your employer fails to address the issue, external support is available:
Acas (Advisory, Conciliation and Arbitration Service)
Acas offers free and impartial advice on employment disputes. Their early conciliation service can help you and your employer reach a settlement without going to a tribunal.
Citizens Advice
Citizens Advice provides practical guidance on employment rights and can help you understand your options for escalating the matter.
Employment Tribunal
As a last resort, you can file a claim with an employment tribunal. This process involves submitting evidence and presenting your case before a judge. Keep in mind that claims must be filed within three months minus one day from the date of the underpayment.
Can I Refuse to Work If I Haven’t Been Paid in the UK?
This is a common question for those experiencing underpayment or non-payment. While it may feel justified to stop working if you haven’t been paid, refusing to work could potentially breach your employment contract.
- Legal Position: UK law generally expects employees to fulfill their contractual obligations unless there’s a fundamental breach by the employer, such as consistent non-payment.
- Risk of Dismissal: Stopping work could lead to disciplinary action or even dismissal unless you’ve taken appropriate steps to resolve the issue.
- Best Approach: Instead of refusing to work outright, raise a grievance or contact Acas for guidance on handling the situation professionally.
If the situation escalates, you may be able to claim constructive dismissal if the non-payment is significant enough to justify leaving your role.
How Late Can an Employer Pay You in the UK?

Employers are required to pay you on the agreed payday as stated in your employment contract. Delayed payment can constitute a breach of contract, and repeated delays may be considered unfair treatment.
Here’s what you need to know:
1. Legally Binding Payday: Employers must pay wages on the date agreed upon, typically weekly or monthly.
2. Action for Late Payments: If payment is delayed, you can:
- Contact your employer or payroll department immediately to identify the reason for the delay.
- Raise a formal complaint if the issue persists.
3. Legal Support: Persistent late payments can be addressed through an employment tribunal or legal action, particularly if they cause financial hardship.
It’s crucial to document any instances of late payment to build a strong case should you need to escalate the matter.
How Long Does an Employer Have to Correct a Payroll Mistake in the UK?

Payroll mistakes, while often unintentional, can have serious implications. Employers are expected to address and rectify such errors promptly.
Here’s what you should know:
- Immediate Resolution: Upon identifying a payroll error, employers should take steps to correct it in the next payroll cycle or sooner if possible.
- Legal Expectations: There is no specific statutory timeframe for correcting payroll errors, but unreasonable delays could breach employment law.
Steps to Take
- Inform your employer immediately if you notice an error.
- Request written confirmation of when the correction will be made.
- If delays persist, seek advice from Acas or Citizens Advice.
Employers are encouraged to act swiftly to avoid legal disputes and maintain employee trust.
How to Prepare for an Employment Tribunal?

Taking your case to an employment tribunal is a formal legal process, and preparation is essential to increase your chances of success.
Below is a step-by-step guide to help you prepare effectively:
1. Understand the Process
Before proceeding, familiarize yourself with how employment tribunals work. Employment tribunals are independent judicial bodies that resolve disputes between employees and employers. Key aspects include:
- Filing the Claim: You must file a claim within three months minus one day of the underpayment incident.
- Tribunal Hearing: Both parties present evidence and arguments to a judge.
- Outcome: The tribunal decides whether your employer breached employment laws and determines compensation or remedies.
2. Gather Evidence
Evidence is the foundation of a successful claim. Collect and organize all relevant documents to support your case, including:
- Payslips: Highlight discrepancies or missing payments.
- Employment Contract: Provide proof of your agreed pay rate, hours, and benefits.
- Timesheets: Show accurate records of hours worked, including overtime.
- Correspondence: Include emails, letters, or notes from meetings where you raised the issue.
- Formal Grievance Outcome: If you raised a formal grievance, the employer’s response will be crucial evidence.
Organize these documents chronologically to present a clear timeline of events.
3. Seek Legal Support
Employment law can be complex, so seeking professional advice is highly recommended. Options include:
- Trade Union Representatives: If you’re a member of a trade union, their representatives can provide legal assistance and advocacy.
- Employment Law Specialists: Solicitors or advisors specializing in employment disputes can guide you on presenting a strong case.
- Pro Bono Services: Charities or community legal services may offer free legal advice if you cannot afford representation.
4. Prepare Your Statement
Prepare a detailed written statement outlining your case. Include:
- A summary of the underpayment issue.
- The steps you took to resolve the issue internally.
- The financial and emotional impact the underpayment has had on you.
- The compensation or remedy you’re seeking.
Practice presenting your statement clearly and confidently, as you may need to explain your case verbally during the hearing.
5. Be Aware of Deadlines and Requirements
Ensure you meet all tribunal deadlines, such as submitting your claim form and evidence. Missing a deadline could jeopardize your case. Familiarize yourself with the tribunal’s procedural rules to avoid common pitfalls.
6. Attend a Preliminary Hearing (if applicable)
In some cases, the tribunal may schedule a preliminary hearing to address procedural matters or clarify the key issues of the case. Use this opportunity to refine your argument and address any questions from the tribunal.
7. Prepare for the Hearing
At the hearing, you’ll need to present your case clearly and respond to questions from the judge and your employer’s representatives. Tips for success include:
- Stay Professional: Remain calm and polite, even if the employer’s arguments are frustrating.
- Be Honest: Stick to the facts and avoid exaggeration.
- Answer Clearly: Respond to questions directly and provide evidence to back your answers.
What to Do If Your Employer Retaliates?

Retaliation by an employer, such as demotion, reduced hours, or dismissal, for raising concerns about underpayment is illegal under UK law. If you face retaliation, you have rights and options to address the situation.
1. Recognize Retaliation
Retaliation can take many forms, including:
- Demotion or Reduction in Responsibilities: Being moved to a less desirable role without justification.
- Reduced Hours or Pay: Facing a cut in hours or pay as punishment.
- Unfair Dismissal: Losing your job after asserting your rights.
- Hostile Work Environment: Experiencing increased scrutiny, verbal abuse, or exclusion from workplace activities.
If you suspect retaliation, document all incidents, including dates, descriptions, and any witnesses.
2. Understand Your Rights
UK law protects employees from unfair treatment or dismissal for asserting their legal rights. The Employment Rights Act 1996 and Equality Act 2010 provide safeguards against:
- Unfair Dismissal: If you’ve been employed for at least two years, you can file a claim for unfair dismissal.
- Detrimental Treatment: Any negative action taken against you for raising a legitimate concern is unlawful.
If you were dismissed, you might also be entitled to notice pay, redundancy pay, or compensation depending on your circumstances.
3. Raise the Issue Internally
Start by raising your concerns with your employer, following these steps:
- Write a Complaint: Submit a written grievance explaining the retaliatory actions and their impact on you.
- Request a Resolution: Suggest ways your employer can rectify the situation, such as reinstating your original hours or role.
- Document Everything: Keep copies of your complaint, your employer’s response, and any evidence of retaliation.
If the employer fails to address the issue, you may need to escalate it.
4. Seek External Support
External support can be crucial in cases of retaliation:
- Acas: Offers free advice and early conciliation services to resolve disputes without litigation.
- Citizens Advice: Provides guidance on your rights and the next steps if you’ve been treated unfairly.
- Legal Representation: Consult an employment solicitor to explore your options for filing a tribunal claim.
5. File an Employment Tribunal Claim
If retaliation leads to unfair dismissal or other detrimental actions, you can file a claim with an employment tribunal. Steps include:
- State the Basis of Your Claim: Clearly outline how the employer’s actions constitute retaliation.
- Provide Evidence: Include documentation of the underpayment issue, your grievance, and the retaliatory actions.
- Claim Remedies: Request compensation for financial losses and emotional distress caused by the retaliation.
Tribunals take retaliation claims seriously, especially if the employer violated employment laws to punish you.
6. Consider Constructive Dismissal
If retaliation creates a hostile work environment, making it impossible for you to continue working, you may resign and claim constructive dismissal.
This is a complex legal route that requires evidence of significant breaches of contract by your employer. Consult a solicitor before taking this step.
Conclusion
Being underpaid is a serious issue that can impact your financial well-being. However, UK laws provide robust protections for employees. By understanding your rights and following the appropriate steps, you can address underpayment effectively.
Remember, resources like Acas, Citizens Advice, and legal professionals are available to support you throughout the process.
