How to Claim Unfair Dismissal in England and Wales
Unfair dismissal claims can feel daunting after a job ends. This guide explains what the process involves, what evidence matters, and where key deadlines often arise.
Unfair dismissal claims often involve strict deadlines, detailed evidence, and formal tribunal procedures. A solicitor can help assess the strengths and risks, organise evidence, and handle settlement discussions. Support can be especially valuable where discrimination, whistleblowing, or complex contract terms are involved.

What Unfair Dismissal Means
Unfair dismissal is a legal claim about whether an employer ended an employee’s employment fairly. It is mainly based on the Employment Rights Act 1996, and the decision is made by an employment tribunal if the case is not settled.
A dismissal can feel unfair without being legally unfair. The tribunal looks at both the reason for the dismissal and the way the employer handled the decision.
The Legal Test in Simple Terms
A tribunal usually considers two linked questions:
- Whether the employer had a potentially fair reason for dismissing
- Whether the dismissal was fair overall in the circumstances, including whether the employer followed a fair process and acted reasonably
Potentially fair reasons under the Employment Rights Act 1996 include:
- Conduct
- Capability or qualifications
- Redundancy
- A legal restriction that prevents the employment continuing
- Some other substantial reason, which is a broad category that can cover certain business or relationship issues
Unfair Dismissal and Other Types of Claim
Unfair dismissal is often confused with other claims that can overlap but are not the same thing.
- Wrongful dismissal is usually about breach of contract, such as not giving the correct notice pay
- Discrimination claims are based on equality law and can arise even where someone does not qualify for an unfair dismissal claim
- Detriment claims can apply where someone is treated badly for a protected reason, even if they are not dismissed
This guide focuses on unfair dismissal, but it flags where other claims commonly appear alongside it.
Constructive Dismissal
Sometimes a person resigns rather than being directly dismissed. A constructive dismissal claim is usually based on the idea that the employer’s actions left the employee with no real option but to resign. These cases often turn on detailed facts and timing, and they can be harder to prove than a straightforward dismissal.
This guide reflects the legal position as at January 2026. The eligibility rules and time limits are central to unfair dismissal claims and are covered in the next sections.
Who Can Make an Unfair Dismissal Claim
An unfair dismissal claim is mainly available to people who are legally classed as employees. This is because the right not to be unfairly dismissed comes from the Employment Rights Act 1996, which focuses on employment relationships.
Employee Status
A person is usually treated as an employee if they work under a contract of employment. In practice, disagreements can arise where someone is described as self employed or a contractor, but the day to day working arrangements look more like employment.
GOV.UK has a short overview of employment status: https://www.gov.uk/employment-status
The Qualifying Period
In many cases, an employee can only claim unfair dismissal after a minimum period of continuous employment. GOV.UK summarises the qualifying period like this:
- Employment started before 6 April 2012, qualifying period is usually one year
- Employment started on or after 6 April 2012, qualifying period is usually two years
Continuous employment is about working for the same employer without a break. It is often straightforward, but it can become more complicated in some situations, for example where there has been a change of employer or a gap in work.
More detail on continuous employment is here: https://www.gov.uk/continuous-employment-what-it-is
When The Qualifying Period Might Not Apply
Some dismissals are treated as automatically unfair. These are linked to specific protected situations, such as pregnancy and maternity related reasons, certain family leave rights, trade union membership or activities, whistleblowing, and some working time and pay rights. In these categories, the usual qualifying period rules can work differently.
GOV.UK lists the main automatically unfair areas here: https://www.gov.uk/dismiss-staff/unfair-dismissals
Who Usually Cannot Claim Unfair Dismissal
There are also situations where the unfair dismissal route is not available, or is limited. Examples commonly include:
- Self employed people and independent contractors
- Members of the armed forces
- Some people who have already settled the dispute through an ACAS settlement or a settlement agreement
- Police officers, with limited exceptions
- Some cases involving unofficial industrial action
Eligibility detail is summarised here: https://www.gov.uk/dismiss-staff/eligibility-to-claim-unfair-dismissal
This guide reflects the position as at January 2026. Some unfair dismissal rules are due to change in stages under the Employment Rights Act 2025, so the qualifying period and time limits may look different in future.
Time Limits and Key Dates
Time limits are a central part of unfair dismissal claims. The main rule comes from the Employment Rights Act 1996. An employment tribunal normally only considers an unfair dismissal complaint if it is presented within three months starting with the effective date of termination.
The Effective Date of Termination
The effective date of termination is the legal date used for the time limit. It is not always the same as the last day worked. For example, it can be:
- the date a notice period ends, if employment ended with notice
- the date the dismissal took effect, if employment ended without notice
The definition is set out in section 97 of the Employment Rights Act 1996: https://www.legislation.gov.uk/ukpga/1996/18/section/97
How The Three Month Time Limit Is Commonly Worked Out
In everyday terms, the time limit is often described as three calendar months minus one day from the effective date of termination. A worked explanation is available here: https://www.acas.org.uk/employment-tribunal-time-limits
Early Conciliation and The Time Limit
Most employment tribunal claims go through early conciliation first. ACAS, the Advisory, Conciliation and Arbitration Service, is a public body that runs this process. It is designed to see whether the dispute can be resolved without a tribunal claim.
Early conciliation affects timing because the law pauses the tribunal time limit while conciliation is taking place. The final deadline is then adjusted using the early conciliation certificate dates.
An overview of how early conciliation works is here: https://www.acas.org.uk/early-conciliation/how-early-conciliation-works
Late Claims and Limited Exceptions
Unfair dismissal has a narrow late claim test. A tribunal may extend time where it was not reasonably practicable to present the claim in time, and it was presented within a further period the tribunal considers reasonable.
The statutory wording is in section 111 of the Employment Rights Act 1996: https://www.legislation.gov.uk/ukpga/1996/18/section/111
Upcoming Change
The Employment Rights Act 2025 provides for longer employment tribunal time limits for most claims, expected to begin from October 2026. Where a change is not yet in force, the existing rules continue to apply.
Time limits in unfair dismissal cases are usually strict, and the deadline can turn on the effective date of termination and early conciliation certificate dates. Some tribunal time limits are due to extend from October 2026 under the Employment Rights Act 2025.
Evidence and Records That Often Matter
- contract of employment and written terms
- dismissal letter and notice details
- disciplinary or redundancy policy relied on
- meeting invitations, notes, and outcomes
- appeal letter and appeal decision
- key emails, messages, or letters about the events
- a simple timeline of key dates and events
In an unfair dismissal claim, an employment tribunal decides what happened and whether the dismissal was fair based on evidence. The most useful evidence often depends on the reason the employer relies on, for example conduct, capability, redundancy, or some other substantial reason.
A case usually involves a mix of documents and personal records. Some of these come from the employer, and some are held by the employee. Tribunals tend to focus on what was said and done at the time, not what people later wish had happened.
What Tribunals Commonly Focus On
Evidence is often used to show:
- the reason the employer gives for dismissing
- what process was followed, for example meetings, warnings, consultation, and appeal stages
- whether the decision appears consistent with the employer’s policies and past practice
- what information the employer relied on, and what the employee was told and given a chance to respond to
Documents That Often Matter
Written documents can carry a lot of weight because they are usually created close to the events. Common examples include:
- the contract of employment and any written terms about notice, duties, and policies
- the dismissal letter and any earlier warning letters
- emails, messages, or letters about the events leading to dismissal
- meeting notes, invitation letters, and outcome letters
- appeal paperwork, including the appeal decision
- employer policies that were relied on, for example disciplinary or redundancy procedures
Personal Records and Timelines
People often find it easier to explain events when there is a clear timeline. A simple chronology can help link documents to key dates, such as when allegations were raised, when meetings happened, when decisions were made, and when employment ended.
Witness evidence can also matter. In tribunal terms this is usually handled through written witness statements and then questions at a hearing. The detail that tends to matter is what a witness actually saw, heard, or did, rather than opinions about what should have happened.
Evidence That Depends on the Type of Dismissal
Some kinds of dismissal tend to involve specific evidence.
- Conduct: investigation records, evidence relied on, consistency with the disciplinary policy
- Capability: performance reviews, targets, training and support offered, medical evidence where health is involved
- Redundancy: the business reason for redundancy, selection criteria, scoring, consultation records, and alternative roles considered
ACAS Early Conciliation and Settlement Options
Many employment tribunal claims follow a stage called early conciliation. This is run by Acas, the Advisory, Conciliation and Arbitration Service. It is designed to give both sides a chance to resolve the dispute without the tribunal deciding it.
Early conciliation is separate from an internal workplace process such as a grievance or an appeal. A dispute can be discussed through Acas even if there are still internal steps happening, but tribunal deadlines still matter and do not disappear.
What Early Conciliation Usually Involves
Early conciliation commonly follows a simple pattern:
- a person notifies Acas that they may bring a tribunal claim
- an Acas conciliator contacts the parties and checks whether settlement talks are possible
- discussions take place for a limited period
- if there is no settlement, Acas issues an early conciliation certificate, which is normally needed to submit a tribunal claim
An overview is here: https://www.acas.org.uk/early-conciliation
How Settlements Are Often Recorded
If a dispute settles through Acas, the outcome is usually recorded in a COT3 agreement. A COT3 is a legally binding agreement made through Acas.
Another common route is a settlement agreement. This is a written agreement between an employer and an employee that can settle statutory employment claims, but it only works for those claims if legal conditions are met. One key condition is that the person signing receives advice from an independent relevant adviser on the terms and effect of the agreement.
A summary of the legal rules for settlement agreements is in section 203 of the Employment Rights Act 1996: https://www.legislation.gov.uk/ukpga/1996/18/section/203
What Settlement Discussions Often Cover
Settlement discussions vary by case, but they commonly touch on:
- money terms, including how any amount is described and when it is paid
- a reference and what it will say
- confidentiality and what can be said about the dispute
- whether there are any practical points to resolve, for example return of property
A settlement can happen at many points, including during early conciliation, after a tribunal claim is submitted, or shortly before a hearing.
Early conciliation is time limited and usually ends with an Acas certificate if there is no settlement. From 1 December 2025, the maximum early conciliation period for new notifications is up to 12 weeks: https://www.legislation.gov.uk/uksi/2025/1153/made
The Usual Steps in an Employment Tribunal Claim
Step 1: Identify Eligibility and Key Dates
This stage usually involves checking whether unfair dismissal is the right legal route, and whether the basic eligibility rules are met. The right not to be unfairly dismissed comes from the Employment Rights Act 1996 and applies mainly to employees.
A common starting point is status. Some people are described as self employed or contractors, but the legal position can depend on the reality of the working relationship. GOV.UK has an overview of employment status: https://www.gov.uk/employment-status
Another early check is the qualifying period. Many unfair dismissal claims require a minimum period of continuous employment, which is usually two years for employment that started on or after 6 April 2012. Some types of dismissal are treated as automatically unfair, and the qualifying period rules can work differently in those categories.
Time limits are often considered at the same time. The usual tribunal deadline for unfair dismissal runs from the effective date of termination, which is the legal date employment ended. It can be the end of a notice period, or the date the dismissal took effect where employment ended without notice. The statutory definition is in the Employment Rights Act 1996: https://www.legislation.gov.uk/ukpga/1996/18/section/97
A short example can help show how dates can differ. If an employee stops working on the day they are dismissed but remains employed through a notice period, the effective date of termination is often the end of that notice period, not the last day worked.
Early conciliation is also factored in at this stage. Most tribunal claims begin with early conciliation through Acas, and the certificate dates are used when working out the final tribunal deadline.
Key Dates Often Noted Early On
- effective date of termination
- date early conciliation is notified to Acas
- date the early conciliation certificate is issued
- dates of any disciplinary outcome and appeal outcome
Tribunal time limits are usually strict, and late claims are only accepted in limited circumstances. Some eligibility and time limit rules are due to change in stages from late 2026 and 2027 under the Employment Rights Act 2025.
Step 2: Start Acas Early Conciliation
This stage usually starts when a person notifies Acas, the Advisory, Conciliation and Arbitration Service, that they may bring an employment tribunal claim. Acas is a public body that offers conciliation, which means it tries to help both sides explore a settlement without the tribunal deciding the dispute.
The notification is often limited to the basic details needed to open the case, such as who the parties are and the general nature of the dispute. An Acas conciliator then usually makes contact to see whether settlement talks are possible.
Early conciliation is time limited. For notifications made on or after 1 December 2025, the early conciliation period can last up to 12 weeks. Notifications made earlier follow the previous maximum period. More detail is here: https://www.acas.org.uk/early-conciliation/how-early-conciliation-works
Early conciliation can affect tribunal timing because the tribunal time limit is adjusted using the early conciliation dates and the certificate details. A general overview of tribunal time limits is here: https://www.acas.org.uk/employment-tribunal-time-limits
What Often Happens During Early Conciliation
- Acas contacts the parties to check whether talks are possible
- settlement terms are discussed in broad terms, including money and practical points
- discussions may move back and forth for a period, depending on how each side responds
- early conciliation ends either with an agreement or with a certificate
Possible Outcomes
- settlement recorded through Acas, often using a COT3 agreement
- no settlement, and an early conciliation certificate is issued so the tribunal process can continue
Early conciliation usually ends with an Acas certificate if the dispute does not settle. The certificate reference is normally needed to submit a tribunal claim, and time limits still apply even while conciliation is ongoing.
Step 3: Submit the Tribunal Claim
This stage usually begins once early conciliation has ended without a settlement and an early conciliation certificate has been issued. The certificate reference is normally included in the tribunal claim.
Employment tribunal claims are commonly submitted online. The claim is often referred to as an ET1 form, even where it is completed through a digital service. An overview of the process is here: https://www.gov.uk/employment-tribunals/make-a-claim
The claim form usually asks for enough detail to explain what the claim is about and what the person is seeking. In unfair dismissal cases, this often includes:
- the claimant and respondent details
- dates of employment and the date employment ended
- the claim type, such as unfair dismissal, and any related claims being brought
- a short account of what happened and why the dismissal is said to be unfair
- what outcome is being sought, such as compensation or another remedy
The respondent details can matter, especially where a business has multiple entities or where there has been a recent restructure. Some disputes also involve more than one respondent, depending on who the legal employer was.
If the claim is accepted, it is normally served on the respondent, who is then given an opportunity to respond. The response is commonly referred to as an ET3.
Tribunal deadlines are strict in most cases, and the final date can depend on both the effective date of termination and the early conciliation certificate dates. Problems with respondent details or missed deadlines can create avoidable procedural issues.
Step 4: Receive the Response and Tribunal Directions
This stage usually starts after the claim has been served on the respondent. The respondent is normally given a set period to respond, commonly through an ET3 response form.
If the respondent disputes the claim, the case usually moves into case management. The tribunal may issue written directions, or it may list a preliminary hearing to deal with practical points. The aim is to set out what needs to happen before a final hearing, and when it needs to happen.
Directions often cover:
- exchanging relevant documents, sometimes called disclosure
- agreeing a core bundle of documents for the tribunal to read
- preparing and exchanging witness statements
- identifying the legal issues and any points that need a decision before the final hearing
- listing dates and time estimates for hearings
Some cases include an early decision on a specific issue, for example whether the claim was in time, whether the claimant is an employee, or whether the tribunal has jurisdiction to hear a particular claim. These are often dealt with at a preliminary hearing.
An overview of the tribunal process is here: https://www.gov.uk/employment-tribunals
Employment tribunal cases often involve formal case management directions. The steps vary depending on the issues in dispute, and some claims involve a preliminary hearing before any final hearing is listed.
Step 5: Prepare Evidence and Witness Statements
This stage usually follows the tribunal’s case management directions. The purpose is to gather the evidence the tribunal will read, and to set out each side’s account in a structured way before the final hearing.
The rules that govern how employment tribunal cases are managed sit within the Employment Tribunals (Constitution and Rules of Procedure) Regulations 2013: https://www.legislation.gov.uk/uksi/2013/1237/contents/made
Exchanging Documents
It is common for both sides to exchange relevant documents. This often includes the documents already held by the employer and the employee, plus anything created during the dismissal process.
Documents exchanged often include:
- contract terms, policies, and handbook extracts relied on
- investigation records, meeting notes, and outcome letters
- emails and messages linked to key events
- performance records, absence records, or redundancy scoring, depending on the reason given for dismissal
- appeal paperwork and the appeal decision
In some cases, the tribunal may also make orders to deal with missing documents or disputes about what should be provided.
The Hearing Bundle
Tribunal directions often require a single bundle of documents for the tribunal to use at the hearing. This is commonly a paginated set of agreed documents. The bundle is usually prepared by one party, then checked and agreed with the other, so everyone is referring to the same pages.
Witness Statements
Witness statements are the written accounts that witnesses rely on at the final hearing. They usually set out what the witness saw, heard, did, and decided, in date order. A witness statement often focuses on:
- what the employer’s reason for dismissal was said to be
- how the decision was reached
- what opportunities were given to respond
- what happened at key meetings and appeals
At the hearing, witnesses are usually asked questions about their statements. The tribunal then considers the statements alongside the documents.
Clarifying The Issues
Many cases also involve agreeing a list of issues, sometimes called a list of issues for the tribunal to decide. This helps keep the hearing focused on the key legal questions, for example whether the reason for dismissal was potentially fair, and whether the overall process and decision were fair in the circumstances.
Witness statements and bundles often include confidential workplace information and personal data. Small differences between documents and recollections can become important in tribunal evidence.
Step 6: Attend the Hearing and Get a Decision
This stage usually begins with a final hearing listed by the employment tribunal. The tribunal considers the documents in the bundle, hears from witnesses, and listens to each side’s case about what happened and why.
Employment tribunals are part of HM Courts and Tribunals Service. A case may be heard by an employment judge sitting alone, or by a panel that includes an employment judge and lay members. The format can vary depending on the type of case and the issues in dispute.
What The Tribunal Usually Decides
In an unfair dismissal claim, the tribunal typically works through two linked questions:
- whether the employer has shown a potentially fair reason for dismissal under the Employment Rights Act 1996
- whether the dismissal was fair in the circumstances, including whether the employer acted reasonably and followed a fair process
Decisions, Remedies, and Separate Hearings
The tribunal may give a decision at the end of the hearing, or it may send a written judgment later. In some cases, the tribunal decides liability first and deals with remedy separately, either by agreement between the parties or because more evidence is needed about remedy.
Remedies can include reinstatement or re engagement in limited cases, and compensation is common where the claim succeeds. In unfair dismissal, compensation is usually discussed in terms of a basic award and a compensatory award, with adjustments depending on the facts, for example earnings after dismissal, contributory conduct, or whether a fair procedure would likely have led to dismissal anyway.
An overview of the tribunal process is here: https://www.gov.uk/employment-tribunals
Many cases settle before a final hearing, even after the claim has been submitted. Where a case goes to a hearing, it is common for the tribunal to issue a written judgment, and some cases have a separate remedy stage.
Outcomes, Compensation, and Practical Costs
Unfair dismissal cases can end in different ways. Some settle during early conciliation or later discussions. Others end with a tribunal judgment, either after a full hearing or after an earlier decision on a specific issue such as time limits or employment status.
Outcomes a Case Can Reach
Common outcomes include:
- a settlement recorded through Acas, often using a COT3 agreement
- a settlement agreement between the parties
- the claim ending without a tribunal deciding the merits, for example because it is withdrawn or struck out
- a tribunal decision that the dismissal was fair
- a tribunal decision that the dismissal was unfair, followed by a decision on remedy
Remedies in Unfair Dismissal Cases
If an unfair dismissal claim succeeds, the tribunal has a range of remedies available. In practice, remedies often fall into two broad categories:
- orders about employment, such as reinstatement or re engagement in some cases
- compensation, which is usually the most common remedy
Compensation in unfair dismissal is commonly discussed in two parts:
- a basic award, which is calculated using a statutory formula that takes account of factors such as age, length of service, and weekly pay, subject to statutory limits
- a compensatory award, which is focused on financial loss caused by the dismissal, assessed on the evidence and subject to statutory limits and tribunal rules
Tribunals may also make adjustments in some cases. For example, compensation can be reduced where the tribunal decides the employee’s conduct contributed to the dismissal, or where the tribunal concludes the dismissal would probably have happened even if a proper procedure had been followed.
Legal Costs and Other Practical Costs
There is currently no fee to submit an employment tribunal claim. That does not mean a case is cost free. Practical costs can include:
- paying for legal advice or representation
- time spent preparing documents and witness evidence
- expenses linked to attending a hearing, such as travel
In many cases, each side pays its own legal costs. Tribunal cost orders can happen in limited situations, for example where a party has acted unreasonably in the way the case is conducted. This is separate from compensation for unfair dismissal.
Compensation and costs depend heavily on the facts, the evidence, and what the tribunal decides about fairness and loss. This guide reflects the position as at January 2026, and some tribunal rules and time limits are due to change in stages from late 2026 and 2027.
Common Mistakes
- note the effective date of termination
- keep key letters, emails, and meeting notes
- record the early conciliation certificate details
- focus on the reason given for dismissal and the process followed
- check whether other claims overlap, such as discrimination or whistleblowing
- assume the last day worked is always the deadline date
- miss early conciliation and tribunal time limits
- rely on verbal recollections alone where documents exist
- overlook internal appeal paperwork and outcomes
- treat every unfair feeling outcome as legally unfair dismissal
Missing a deadline can end a claim before the tribunal considers what happened. Time limits often turn on the effective date of termination and early conciliation certificate dates.
Common Questions
The usual time limit is three months starting with the effective date of termination, which is the legal date employment ended. Early conciliation through Acas affects how the deadline is worked out, because the final date is adjusted using the certificate dates.
An internal appeal can be important evidence, but it does not automatically extend the tribunal time limit. The deadline usually still runs from the effective date of termination, with adjustments linked to early conciliation.
Many unfair dismissal claims need a qualifying period of continuous employment, which is often two years for employment that started on or after 6 April 2012. Some dismissals are treated as automatically unfair, and the qualifying period rules can work differently in those categories. Other claims, such as discrimination, are separate from unfair dismissal and have their own rules.
Constructive dismissal is where an employee resigns but argues that the employer’s actions effectively ended the employment. These cases often focus on whether there was a serious breach of contract and whether the resignation was closely linked to that breach.
A COT3 is a legally binding settlement recorded through Acas. A settlement agreement is a written agreement between the parties, and it can only settle certain employment claims if legal conditions are met, including advice from an independent relevant adviser.
There is currently no fee to submit an employment tribunal claim. Other costs can still arise, such as paying for advice or representation, and expenses linked to preparing evidence and attending a hearing.
Compensation is often discussed as a basic award and a compensatory award. The amounts depend on the facts, the evidence, and what the tribunal decides about loss and fairness. In some situations, compensation can be reduced, for example where conduct is found to have contributed to dismissal.
Reinstatement and re engagement are remedies the tribunal can order in some cases, but they are not the most common outcome. Many cases, where they succeed, end with compensation instead.
Some terms that appear frequently in unfair dismissal cases include:
- Effective date of termination, the legal date used to calculate the time limit
- Early conciliation certificate, the Acas certificate reference usually needed for a tribunal claim
- ET1 and ET3, the common names used for the claim and response forms
- Preliminary hearing, a hearing that deals with specific issues such as time limits or employment status
- Remedy, what the tribunal orders after deciding whether a dismissal was unfair
