Wrongful Dismissal: What It Is and How It Differs from Unfair Dismissal

Many people use the terms wrongful dismissal and unfair dismissal interchangeably. They are not the same thing. Understanding the difference matters because the claims have different rules, different remedies, and different time limits.

The core distinction

Wrongful dismissal is a contract claim. Your employer dismissed you in a way that broke your employment contract. The most common example is dismissal without the notice the contract (or the law) required.

Unfair dismissal is a statutory claim. It exists because Parliament decided that employees should have protection against dismissal that lacks a fair reason or a fair process, regardless of what the contract says. The right is set out in Part X of the Employment Rights Act 1996.

The two claims can overlap. Being dismissed instantly for alleged gross misconduct you did not commit could give rise to both: a wrongful dismissal claim for the unpaid notice, and an unfair dismissal claim for the inadequate investigation.

No qualifying period for wrongful dismissal

One of the most important practical differences is the qualifying period.

To bring an ordinary unfair dismissal claim, you generally need 2 years of continuous employment where employment ends before 1 January 2027, and 6 months where it ends on or after that date (Employment Rights Act 2025; commencement regulations made, SI 2026/559). If your employment ends before you reach the qualifying period, the statutory claim is not available to you.

Wrongful dismissal has no such requirement. Because it is a contract claim - essentially a claim that the employer breached an agreement - you can bring it from the first day of work. This makes it the only dismissal claim available to employees with short service.

What counts as wrongful dismissal?

There are several ways a dismissal can be wrongful.

Dismissed without notice

Every employment contract includes a notice period. It may be stated explicitly, implied by custom and practice, or - if the contract is silent or gives less than the minimum - replaced by the statutory minimum notice under section 86 of the Employment Rights Act 1996.

The statutory minimum is:

• 1 week's notice after 1 month of employment
• 1 week per complete year of service, up to a maximum of 12 weeks

If your contract gives more than the statutory minimum, your contract notice applies. If your contract gives less, the statutory minimum replaces it. To see the notice you are entitled to, use our notice period calculator.

Dismissing you without going through that notice period - unless gross misconduct justifies it - is a breach of contract.

Summary dismissal without gross misconduct

An employer can dismiss an employee immediately, without notice, if the employee has committed gross misconduct. This is sometimes called summary dismissal.

But summary dismissal is only lawful if the conduct genuinely justifies it. Gross misconduct typically involves serious dishonesty, theft, violence, or behaviour that fundamentally destroys the trust needed for the employment relationship to continue. Minor misconduct, or misconduct that has been tolerated previously, will rarely meet that standard.

If an employer dismisses you instantly for something that does not amount to gross misconduct, that dismissal is wrongful. You are entitled to the notice you were owed.

Note that even where gross misconduct is alleged, a separate unfair dismissal claim may still exist if the employer failed to carry out a reasonable investigation or follow a fair procedure. That claim needs the qualifying service (2 years, or 6 months where employment ends on or after 1 January 2027), but it sits alongside the wrongful dismissal claim, not instead of it.

Fixed-term contract ended early

If you have a fixed-term contract and your employer brings it to an end before the agreed end date, that is a breach of contract unless the contract contained an explicit right to terminate early. You can claim damages for the earnings lost over the remainder of the term.

Constructive wrongful dismissal

If your employer commits a serious breach of contract and you resign in response, that resignation can constitute a constructive dismissal in law. For wrongful dismissal purposes, the question is whether the employer's conduct was a breach of contract. This is distinct from the broader constructive unfair dismissal question, which also looks at whether the breach destroyed the employment relationship in a way that makes the resignation reasonable.

Pay in lieu of notice

Many contracts contain a pay in lieu of notice (PILON) clause. This gives the employer the right to end your employment immediately by paying you the equivalent of your notice pay rather than requiring you to work it out.

If your contract contains a valid PILON clause, the employer can lawfully invoke it. There is no breach of contract, and no wrongful dismissal claim.

If your contract does not contain a PILON clause, and the employer simply pays you in lieu rather than allowing you to work your notice, the immediate termination is itself a breach of contract. The payment they made may reduce your losses, but the wrongful dismissal claim remains available.

What you can recover

Wrongful dismissal damages are designed to put you in the financial position you would have been in if the contract had been performed properly.

In practice, that means the net earnings you would have received during your notice period, minus:

• Any income you earned from another employer during that period (you have a duty to mitigate your losses)
• An adjustment for income tax and National Insurance (damages for lost earnings are usually expressed on a net basis)

You cannot recover:

• Compensation for distress, upset, or injury to feelings (those are available in discrimination claims, not straightforward contract claims)
• Losses beyond the notice period - for example, difficulty in finding a new job or long-term career damage
• Any sum for the manner of your dismissal, however badly it was handled

This is one of the key practical limits of wrongful dismissal. The claim covers the notice window only. If the real loss is losing a well-paid job for good, unfair dismissal - where it is available - gives a much broader remedy.

Where to bring your claim

You have two options.

The employment tribunal hears most wrongful dismissal claims. It is quicker and cheaper than going to court. Before issuing a claim, you must go through ACAS Early Conciliation. The time limit is 6 months less 1 day from the effective date of termination where it is on or after 1 October 2026 (3 months less 1 day before then) - the same deadline as for unfair dismissal. The employment tribunal currently caps wrongful dismissal awards at £25,000.

The civil courts - the County Court or High Court - handle claims above £25,000. The limitation period is 6 years from the breach of contract. There is no ACAS Early Conciliation requirement for civil court claims. If your notice period is long and your salary is high, the civil court route may produce a better financial outcome, though the process is slower and the costs are higher.

When both wrongful and unfair dismissal apply

The two claims can and often do run together in the same proceedings. Here is a concrete example.

An employee with 3 years of service is dismissed instantly, without notice, for allegedly stealing from the till. They deny it. The employer conducted a brief investigation lasting two days and did not allow a companion at the disciplinary hearing.

Wrongful dismissal claim: was the conduct serious enough to justify summary dismissal? If the evidence was insufficient to establish gross misconduct, the employee was entitled to their contractual notice. A claim for that unpaid notice period is available regardless of length of service.

Unfair dismissal claim: did the employer have a genuine belief in the misconduct, did they carry out a reasonable investigation, and did they follow a fair procedure? The qualifying period is met. The inadequate investigation and absence of a companion may well make the dismissal procedurally unfair, opening the door to a compensatory award substantially larger than the notice pay alone.

Both claims can be brought in the same employment tribunal proceedings.

The £25,000 tribunal cap in practice

The cap on wrongful dismissal in the employment tribunal is worth bearing in mind for anyone with a long contractual notice period. A senior employee on a £120,000 gross salary with 6 months' contractual notice would lose about £60,000 of gross pay over the notice period - well over twice the £25,000 tribunal cap. Damages are usually assessed on net pay, after tax and National Insurance, so the actual claim would be lower than £60,000, but on these figures it would still be above the cap.

In that situation, pursuing the claim in the civil courts may recover more. The trade-off is time and litigation cost. In similar situations, claimants have weighed the certainty of tribunal proceedings against the higher potential recovery in court before deciding which route to take.
