Employees on a fixed-term contract have the same core statutory rights as permanent staff and additional protection against being treated less favourably purely because their contract has an end date. This guide explains those rights for 2026/27, including the four-year rule on successive renewals.
The Right to Equal Treatment
Fixed-term employees have the right not to be treated less favourably than a comparable permanent employee doing the same or broadly similar work, purely because their contract is fixed-term, unless the employer can objectively justify the difference β for example in pay, access to training, pension arrangements, or entitlement to a benefit.
This does not mean every fixed-term employee must be treated identically in every respect, but any less favourable treatment based on fixed-term status specifically needs an objective business justification rather than simply being administratively convenient.
The Four-Year Rule on Successive Contracts
If an employee has been employed on successive fixed-term contracts for four or more years, any further renewal is automatically treated as a permanent contract, unless the employer can objectively justify continuing to use a fixed-term arrangement for a genuine business reason.
A gap between contracts does not automatically reset this clock to zero β how continuity is affected depends on the length and reason for any gap, so employers relying on repeated short renewals should take specific advice rather than assuming a break in dates avoids the rule.
When a Fixed-Term Contract Ends
If a fixed-term contract simply expires and is not renewed after genuinely coming to its natural end, this can still count as a dismissal in employment law terms, meaning unfair dismissal protection can apply once the qualifying period of continuous service is met, and a non-renewal for redundancy-type reasons can trigger statutory redundancy pay.
Employees should be given the same access to internal vacancies and consultation about non-renewal as would be expected for a permanent employee facing redundancy, where the reason for non-renewal is that the underlying need for the role has ended.
Frequently Asked Questions
Do fixed-term employees get the same holiday and sick pay as permanent staff?
Generally yes β fixed-term employees are entitled to broadly the same statutory rights, pro rata where relevant, as comparable permanent employees, including holiday entitlement and Statutory Sick Pay, unless an employer can objectively justify a genuine difference.
When does a fixed-term contract automatically become permanent?
Once an employee has been continuously employed on successive fixed-term contracts for four years or more, any further renewal is treated as permanent by law, unless the employer can objectively justify continuing on a fixed-term basis for a specific business reason.
Can my employer just let my fixed-term contract lapse without any process?
Not without risk β a genuine non-renewal at the natural end of a fixed-term contract can still count as a dismissal for employment law purposes, so once you have enough qualifying service, unfair dismissal protections and, where the role has genuinely ended, redundancy pay rules can apply.

Am I entitled to redundancy pay if my fixed-term contract is not renewed?
You can be, if the reason your contract is not renewed is that the need for your role has ended (a redundancy situation) and you have enough qualifying continuous service, in the same way a permanent employee would be entitled to statutory redundancy pay in equivalent circumstances.
Does a short gap between fixed-term contracts reset the four-year clock?
Not automatically β whether a gap breaks continuity depends on its length and the reason for it, so a series of short renewals with brief breaks in between will not necessarily avoid the four-year rule, and specific advice should be taken if this is relied upon.
Can an employer ever justify treating fixed-term staff less favourably?
Yes, but only where there is a genuine, objective business reason for the difference in treatment that goes beyond the employee simply being on a fixed-term contract β a justification has to relate to a real operational need, not just administrative convenience.
Can a fixed-term employee be excluded from a redundancy selection pool?
No β fixed-term employees generally have to be included in the same redundancy selection process and pool as comparable permanent employees where the roles are genuinely similar, rather than being singled out for non-renewal purely because of their contract type.
Do I need a minimum length of service to bring an unfair dismissal claim after a fixed-term contract ends?
In most cases yes β the same qualifying period of continuous service that applies to permanent employees also applies to fixed-term employees, so continuous employment across successive contracts (including any linked gaps) generally needs to be worked out first.
Can I ask my employer for a written statement explaining why I am on a fixed-term contract?
Yes β an employee who believes they have been treated less favourably because of their fixed-term status can ask their employer for a written statement of reasons, and the employer should respond within a reasonable time.
Does a fixed-term contract need to state an end date or a specific ending event?
Yes β a fixed-term contract should identify either a specific end date, the completion of a particular task, or the end of a specific event, since this is what distinguishes it from an open-ended permanent contract.
