A dismissal handled without following the correct employee termination procedure exposes a UK employer to Employment Tribunal claims, uncapped compensation in discrimination cases and reputational damage that long outlasts the case itself. For a founder or senior leader making this decision without a dedicated HR team, the risk is compounded by unfamiliarity with the legal framework.
This guide explains the employee termination procedure in the UK clearly: what the law requires, what a fair process looks like and how to handle the conversation with care.
What Is Termination of Employment?
Termination of employment refers to the ending of an employment contract, whether that ending is initiated by the employee or the employer. The distinction matters in UK law because different rules, entitlements and protections apply depending on how and why the relationship ends.
Types of Terminations
UK law recognises four primary types of termination:
- Dismissal with Notice: The standard route for conduct or capability issues, where the employer ends the contract and works the employee through their notice period or pays them in lieu of it.
- Summary Dismissal: Immediate termination without notice, reserved for cases of gross misconduct such as theft, violence or serious breach of trust.
- Redundancy: Termination because the role itself is no longer required due to business restructuring, closure or a reduction in workforce.
- Fixed-Term Contract Expiry: When a contract ends on its agreed date. Under UK law, this is still classified as a dismissal and carries the same procedural obligations.
Legal Considerations for Dismissing an Employee in the UK
Knowing how to dismiss an employee lawfully in the UK requires more than having a reason for the decision. The Employment Rights Act 1996 sets out that a dismissal is only potentially fair if it is based on one of five specific grounds and carried out through a procedurally fair process.
The Five Fair Reasons for Dismissal:
- Capability: The employee cannot perform the role to the required standard, whether due to performance issues or ill health.
- Conduct: The employee's behaviour warrants disciplinary action, up to and including dismissal.
- Redundancy: The role is no longer required by the business.
- Statutory Illegality: Continuing the employment would breach a legal obligation, such as an employee losing the driving licence required for their role.
- Some Other Substantial Reason (SOSR): A catch-all category covering legitimate business reasons that do not fall into the four above.
The Two-Year Rule
Employees generally need two years of continuous service before they can bring an ordinary unfair dismissal claim to an Employment Tribunal. Exceptions apply, including dismissals related to protected characteristics, whistleblowing or pregnancy, where day-one rights are in force regardless of tenure.
Procedural fairness is not optional. Having a substantive reason for the dismissal is necessary but not sufficient. Tribunals assess both the reason and the process, and a procedurally flawed dismissal can be found unfair even when the underlying reason was sound.
Legal Frameworks and Obligations
Three pieces of legislation and statutory guidance govern the employee termination procedure in the UK:
- The Employment Rights Act 1996: The primary legislation governing dismissal rights, notice entitlements and redundancy.
- The Equality Act 2010: Prohibits dismissal on the grounds of protected characteristics, including age, disability, race, sex, religion and several others.
- The ACAS Code of Practice on Disciplinary and Grievance Procedures: The statutory code that Employment Tribunals refer to when assessing procedural fairness. Failure to follow it can increase any Tribunal award by up to 25 per cent.
What Constitutes Unfair Dismissal?
Unfair dismissal occurs when the reason for termination was not one of the five fair reasons, or when the process used to reach the decision did not meet the standard required by the ACAS Code of Practice.
Certain categories of dismissal are treated as automatically unfair, regardless of the employer's reason or the quality of the process followed:
- Discrimination: Dismissal connected to a protected characteristic under the Equality Act 2010.
- Whistleblowing: Dismissal following a protected disclosure about wrongdoing in the organisation.
- Health and Safety: Dismissal for refusing to work in conditions the employee reasonably believed to be dangerous.
- Maternity and Pregnancy: Any dismissal connected to pregnancy, maternity leave or related circumstances.
- Trade Union Membership: Dismissal for participating in, or seeking to participate in, trade union activities.
- Constructive Dismissal: Where an employee resigns in response to a fundamental breach of contract by the employer, such as sustained bullying or the unlawful withholding of pay. The resignation is treated in law as a dismissal.
The financial exposure from an automatically unfair dismissal claim is significant. Compensation in discrimination cases is uncapped. For founders and senior leaders, the decision to terminate carries more legal weight than it may appear from the outside, and how that decision affects how your staff see employee turnover is a further consideration that sits beyond the immediate legal risk.
What to Expect During a Termination Process
How do you terminate an employee fairly? The answer lies in the sequence the ACAS Code sets out, and departing from that sequence without good reason weakens the employer's position at Tribunal.
Pre-Termination
Before any dismissal decision is made, the employer must:
- Investigate: Gather the facts that support the potential dismissal. For conduct cases, this typically means speaking to witnesses, reviewing documentation and establishing a clear picture of events before any formal hearing is convened.
- Issue a Written Invitation: Notify the employee in writing that a disciplinary hearing is being held, setting out the nature of the allegation and giving reasonable time to prepare.
- Hold the Disciplinary Hearing: The formal meeting at which the employee has the opportunity to respond to the case against them.
- Right to be Accompanied: Employees have a statutory right under the Employment Relations Act 1999 to bring a colleague or a Trade Union representative to any disciplinary hearing. This right cannot be waived by the employer.
Notice of Termination
Statutory minimum notice periods under the Employment Rights Act 1996 are:
- One month to two years of service: One week's notice
- Two to 12 years of service: One week for every full year worked
- 12 or more years of service: Capped at 12 weeks
Two alternatives to working the notice period are available where contractually permitted:
- Pay in Lieu of Notice (PILON): The employer pays the employee the equivalent of their notice period salary without requiring them to continue working.
- Garden Leave: The employee remains on the payroll and bound by their contract during the notice period, but is asked not to attend work. Typically used where protecting commercially sensitive relationships or information is a concern.
Entitlements on Termination
The employee termination procedure is not complete until all financial obligations have been settled. These include:
- Outstanding Salary and Contractual Benefits: All pay owed up to the termination date, including any bonuses or commission due under the contract.
- Accrued Holiday Pay: Employees are entitled by statute to be paid for any annual leave they have accrued but not taken by their last day.
- Statutory Redundancy Pay (SRP): Employees with two or more years of continuous service dismissed for redundancy are entitled to SRP, calculated on the basis of age, weekly pay (capped at £643 per week from April 2024) and years of service.
- The P45 Form: The employer must issue a P45 to the employee after their final pay is processed, recording their tax code and earnings to date in the tax year.
How to Fire an Employee Respectfully
Knowing how to fire an employee with legal correctness is one challenge. Doing it with care for the person on the other side is another, and founders managing this without HR support often find the second harder than the first.
Knowing how to fire someone nicely, in a way that holds up legally and preserves dignity, comes down to a handful of practical decisions made before the meeting begins:
- Be direct and clear: Avoid corporate language that obscures the message. The employee should leave the room with no doubt about the decision and the reason for it.
- Use the evidence: Ground the conversation in the documentation gathered during the investigation. Specificity makes the decision easier to understand and harder to dispute.
- Keep it brief: The meeting should be long enough to cover the reason, the process followed and the practical next steps. It should not extend into a negotiation.
- Prepare for an emotional response: Shock, anger and distress are all normal reactions. Allocate time, have water available, and do not rush the employee out of the building.
- Offer support where possible: A reference, where company policy permits, or access to outplacement support where the business can provide it, closes the meeting on terms the employee can use.
- Manage the exit with care: Agree in advance on the logistics: return of equipment, access cards and keys, handover of work, and the internal communications message the team will receive. Handled badly, the exit process damages trust with the employees who remain.
Protecting Your Business and Upholding Compliance
A sound employee termination procedure protects the business in two directions: it reduces the risk of a successful Tribunal claim and it maintains the employer's standing with the team that remains. Employment Tribunals assess both the reason for dismissal and the process used to reach it. Following the ACAS Code of Practice throughout gives the employer the strongest available defence if a claim is brought, and non-compliance can increase any Tribunal award by up to 25 per cent.
For founders and senior leaders building teams in London, the operational environment matters too.
