If your employer has not paid wages, overtime, commission, sick pay, notice pay or holiday pay correctly, the practical question is usually not whether something has gone wrong but what to do next, how fast to act, and which route is worth using. This guide explains how unpaid wages and holiday pay claims in the UK usually work, how to organise your evidence, when to use an internal grievance, when ACAS Early Conciliation may matter, and when court or tribunal options may need a closer look. It is designed as a page to return to whenever your pay dispute changes, a deadline approaches, or you need a clear checklist before taking the next step.
Overview
This section gives you a working map of the main routes for recovering money you are owed. In many employment pay disputes, the hardest part is not writing the complaint but choosing the right path before time limits become a problem.
Unpaid wages claims can cover more than missing basic salary. Depending on the facts, a worker may be trying to recover:
- basic wages not paid on the normal payday
- underpaid salary after deductions or payroll errors
- overtime or commission that should have been paid under the contract or established practice
- accrued but unpaid holiday pay
- pay for untaken holiday at the end of employment
- statutory or contractual notice pay
- unauthorised deductions from wages
The label matters because the legal route can change depending on what you are claiming and whether you are still employed. A simple payroll mistake may be resolved quickly through HR or payroll. A wider dispute about pay calculations, worker status or holiday entitlement may need a formal complaint and external action.
Start with the basics. Before accusing your employer of refusing payment, check:
- your employment contract or written statement
- recent payslips
- timesheets, rotas and clock-in records
- holiday records and leave approvals
- staff handbook terms on overtime, bonus or commission
- bank statements showing what was actually paid
- emails or messages where pay was agreed or explained
Many disputes turn on one missing detail: whether overtime had to be authorised, whether commission had conditions attached, whether leave year rules affected holiday carry-over, or whether deductions were allowed by contract. A calm document check at the start often saves time later.
Once you know roughly what is missing, write a short pay breakdown. Set out each pay period, what you expected, what you received, and the difference. Keep it in date order. This becomes the foundation for your complaint, grievance, ACAS discussion or claim form.
In practical terms, the common escalation path is:
- raise the issue informally with payroll, HR, line manager or owner
- send a written request for payment with your calculation attached
- if unresolved, use the employer's formal grievance process
- consider ACAS Early Conciliation if a tribunal route may be relevant
- take advice on whether tribunal or court is the better forum for your particular claim
If you are unsure how to structure a formal complaint at work, our Employment Grievance Procedure UK: How to Raise a Formal Complaint at Work guide is a useful companion piece. If a tribunal route may be in view, the ACAS Early Conciliation Guide: Deadlines, Process and What Happens Next can help you understand the pre-claim stage.
The key point is simple: unpaid wages claim UK problems are often easier to resolve when you act early, set out the figures clearly, and keep the discussion focused on evidence rather than emotion.
Maintenance cycle
This section explains how to keep your claim position up to date. Pay disputes are rarely static. Amounts change every payday, new evidence appears, and deadlines may start running sooner than people expect.
A useful maintenance cycle is to review the issue at four points: immediately after the underpayment, after your first written complaint, after any internal grievance outcome, and before any formal deadline expires.
1. Within the first few days
Confirm the shortfall and ask for an explanation in writing. A neutral email works well. State the pay date, the amount you expected, the amount received, and ask when the balance will be paid. If it is a holiday pay claim UK issue, identify the leave dates and the rate you believe should have applied.
At this stage, preserve evidence. Download payslips, save screenshots of rotas and hours, and keep copies outside your work account where appropriate. If your access to systems may disappear because your job is ending, do not leave collection to the last minute.
2. After the first response
If the employer says the issue is being checked, diarise a follow-up date. If they deny liability, ask them to explain the basis for the decision. You are looking for specifics, not broad statements. For example:
- Which contract term do they rely on?
- Which holiday calculation method are they using?
- Why was a deduction made?
- Why are certain hours or commission items excluded?
The clearer their position becomes, the easier it is to assess whether this is a payroll correction, a contractual dispute, or a more formal unlawful deduction issue.
3. After raising a formal grievance
If informal contact fails, move to a written grievance. Attach your pay schedule and supporting documents. Ask for:
- payment of the amount owed
- correction of future payroll
- a written explanation of calculations
- repayment by a specific date
Review the outcome carefully. Employers sometimes offer partial payment without explaining the rest. If the figures still do not make sense, do not assume the matter is settled. Update your schedule and mark what remains disputed.
4. Before any external step
Before ACAS, tribunal or court action, refresh your file. Check whether the amount claimed has increased, whether the legal description still fits, and whether any time limit concerns have become urgent. If the dispute has developed over a series of deductions, make sure your timeline reflects the latest missed payments.
This is also the right stage to ask whether a court debt or breach of contract route might be relevant, especially after employment has ended, or whether an employment tribunal route is more suitable. The answer depends on the facts and should be considered carefully. Time limits can differ, so readers should avoid relying on memory alone. Our UK Limitation Periods Guide: How Long You Have to Bring a Claim is a useful checkpoint for the broader issue of claim deadlines.
As a habit, return to your file each payday until the issue is resolved. That simple review cycle helps you spot repeated underpayments, fresh deductions, or a growing holiday pay shortfall.
Signals that require updates
This section highlights the moments when you should stop relying on your original complaint and refresh your position. In pay disputes, old assumptions often become inaccurate.
Update your records and reassess your next step if any of the following happens:
- Another payday passes without payment. Your total loss may have increased and the pattern may now look more serious.
- Your employment ends. Final salary, accrued holiday, notice pay and deductions often become central at this point.
- Your employer changes its explanation. A payroll error response may turn into a contractual dispute once challenged.
- You receive only part payment. Partial settlement can hide continuing disagreement about rates, hours or deductions.
- You discover missing evidence. New timesheets, emails or leave records may strengthen or weaken part of your claim.
- Your status is disputed. If the employer says you were self-employed rather than a worker or employee, the legal route may need closer analysis.
- There is a holiday year change. Holiday accrual, carry-over and termination calculations may need updating.
- A deadline is approaching. Any sign that time limits may matter should trigger immediate review.
It is especially important to revisit a holiday pay claim when your working pattern is irregular. Workers with variable hours, shift patterns, commission-linked earnings or overtime often focus only on days taken, when the real dispute is the rate used to calculate pay for those days. In other words, the issue may not be whether you had holiday, but whether your holiday pay reflected your normal pay properly.
Another update trigger is retaliation or relationship breakdown. If the pay complaint leads to disciplinary pressure, threats, reduced shifts or dismissal, the case may no longer be just about unpaid salary. At that point, wider employment rights may be engaged, and the strategy may need to change quickly.
Because search intent also shifts over time, this topic is worth revisiting whenever public guidance changes, tribunal procedure is updated, or common employer practices evolve. For readers, that means not treating any old note, forum post or generic template as timeless. Recheck your wording, figures and route before acting.
Common issues
This section covers the disputes readers most often struggle to classify. The practical aim is to help you match the problem to the evidence you need and the route you may need to consider.
Employer not paying wages at all
If your full pay has not arrived, gather the contract, payslip history, timesheets and bank statements. Ask first whether there has been an administrative delay, but do not let vague promises drift. Confirm in writing that wages are overdue and request immediate payment. If the problem repeats, treat it as a formal employment pay dispute rather than a one-off mistake.
Unauthorised deductions from wages
This often appears as reduced pay rather than no pay. Common examples include deductions for stock loss, till shortages, training costs, uniform costs or alleged overpayments. The starting question is whether the deduction was authorised by law, by contract, or by your prior written agreement. If none of those applies, the deduction may be challengeable.
Unpaid overtime
Overtime claims depend heavily on wording and workplace practice. Was overtime guaranteed, compulsory, voluntary, pre-authorised, or regularly worked with management knowledge? Even where the contract is unclear, a long pattern of paid overtime can matter. Keep rosters, approval messages and evidence that the hours were actually worked.
Commission and bonus disputes
These can be harder than salary disputes because terms are often conditional. Check trigger dates, cancellation rules, performance thresholds and clawback clauses. Ask for the commission scheme in writing if you do not already have it. If the employer not paying wages UK problem includes unpaid commission, separate each sale or trigger event in your calculation.
Holiday pay underpayment
A holiday pay claim may involve:
- not being paid when leave was taken
- being paid at the wrong rate
- not being paid for accrued holiday on termination
- being told you had no entitlement when you likely did
The evidence usually includes leave requests, holiday records, payslips and details of how your normal pay is made up. If your earnings vary, your holiday pay question may be more complex than a simple day's pay calculation.
Final pay after leaving
Many workers first think about recover unpaid salary UK options after the job ends. Final pay disputes often combine several items: last wages, notice pay, accrued holiday and deductions for equipment or training. Ask for a final breakdown in writing and compare it to your contract and leave record.
Insolvency concerns
If the employer appears to be insolvent or stopping trading, speed becomes more important. Preserve your documents, note the dates, and seek route-specific guidance quickly. Recovery options can change significantly where the business cannot pay in the ordinary way.
Fear of legal costs
Many readers delay action because they assume any formal step means immediate legal expense. In reality, the first useful actions are usually evidence gathering, internal complaint, grievance and early settlement attempts. A clear paper trail also helps you assess whether formal proceedings are worth the effort.
Across all of these issues, the most common mistake is writing an angry complaint without a schedule of loss. A short, dated table of what you are owed is often more persuasive than pages of narrative.
When to revisit
This final section is a practical checklist for returning to the issue at the right time. If you use this page as a reference, come back whenever one of these moments applies.
- On every payday: check whether the shortfall has been corrected, repeated or partly resolved.
- When your employer responds in writing: compare their explanation with your contract and records.
- Before filing a grievance: update the amount claimed and attach the latest evidence.
- Before starting ACAS Early Conciliation: make sure your timeline and figures are accurate and complete.
- When employment ends: recalculate final salary, accrued holiday and any notice pay issues immediately.
- If your role, hours or pay structure changes: review whether the dispute now includes commission, overtime or holiday rate issues not previously identified.
- If deadlines may be close: stop relying on old assumptions and check the relevant time limits urgently.
A practical action plan for most readers looks like this:
- Write down exactly what has not been paid.
- Collect your contract, payslips, timesheets, leave records and bank statements.
- Send a short written request for payment and explanation.
- If unresolved, raise a formal grievance with a clear calculation attached.
- Keep reviewing the file at each new pay event.
- If internal steps fail, consider ACAS and the appropriate external route without delay.
Return to this guide on a scheduled review cycle if your case is ongoing. Pay disputes often develop in stages, and what began as one missed payment can become a broader holiday pay or deduction claim. The value in revisiting the topic is not just legal accuracy. It is practical control: updated figures, better evidence, a clearer route, and fewer missed opportunities to recover money you are owed.
