UK employment probation periods are entirely contractual - the Employment Rights Act 1996 does not specify any statutory probation. The duration, terms, and conditions are set by the contract. Typical durations are 3-6 months for entry-level roles and 6-12 months for senior or skilled positions.
This guide covers the statutory rights that apply during probation, the specific contractual terms that typically operate, the route through performance issues, and the practical considerations around probation review and confirmation.
Statutory rights during probation
Most statutory employment rights apply from day one of employment, regardless of probation status. Anti-discrimination protection under the Equality Act 2010 applies from day one for the nine protected characteristics: age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, sexual orientation.
Other day-one rights: itemised payslip, statutory minimum wage, working time protections (rest breaks, 48-hour week opt-out), Statutory Sick Pay (subject to eligibility criteria), holiday accrual, pension auto-enrolment (subject to age and earnings thresholds), maternity/paternity rights (subject to qualifying service).
Statutory minimum notice from employer to employee during probation: 1 week during the first month, then 1 week per year of service capped at 12 weeks. Contracts typically specify shorter notice during probation (often 1 week each side) than after confirmation.
The right to NOT have unauthorised deductions from wages under section 13 ERA 1996 applies from day one. Where the contract permits specific deductions (training cost recovery, uniform charges) those are permitted; arbitrary or unauthorised deductions can be challenged at tribunal within 3 months.
Rights that require qualifying service
Unfair dismissal protection under section 94 ERA 1996 requires 2 years of continuous service in most cases. The Government has proposed changes through the Employment Rights Bill 2024 to make unfair dismissal a day-one right, but the legislation timeline and final provisions are not yet finalised at time of writing.
During the qualifying period (probation or first 2 years), the employer can dismiss with contractual notice without needing to show a fair reason in the way required for protected employees. Automatically unfair dismissal reasons (whistleblowing, asserting statutory rights, pregnancy-related, certain trade union activity) apply from day one.
Right to request flexible working: requires 26 weeks of continuous service to make a formal flexible working request under the Employment Rights (Flexible Working) Act 2023. Informal requests can be made any time but the formal protection only applies after qualifying service.
Statutory redundancy pay under chapter II part XI ERA 1996 requires 2 years of service. Redundancy during probation typically does not attract statutory redundancy pay; the dismissal may be characterised as 'failure of probation' or otherwise.
Performance management during probation
Reasonable employers conduct probation review meetings at defined points (typically 1 month, 3 months, 6 months for a 6-month probation). The reviews assess performance against the role requirements and identify any issues for improvement.
Where performance concerns arise, a Performance Improvement Plan (PIP) is the standard route. The PIP sets out specific improvement objectives, support to be provided, timeline (typically 4-8 weeks), and the consequences of not meeting the standard. Even during probation, a fair process improves the employer's position if dismissal becomes necessary.
Disability and reasonable adjustments: where performance issues relate to disability under the Equality Act 2010, the employer has a duty to make reasonable adjustments. Failing to do so before dismissal can result in discrimination claim even during probation. The 2-year unfair dismissal threshold does not apply to discrimination claims.
Practical action: where probation concerns emerge, engaging constructively with the employer, requesting clear feedback, and demonstrating responsiveness typically produces better outcomes than defensiveness. Where the employer is acting reasonably, working with the process usually preserves the role.
Probation failure and dismissal
Where probation is not confirmed, the employer can typically dismiss with the contractual notice period. Most contracts specify shorter notice during probation (1 week each side common) than after confirmation. The dismissal can be 'on notice' (worked or paid out) or with PILON (Pay In Lieu of Notice).
Reasons for dismissal during probation: performance concerns not resolved through PIP, conduct issues, attendance issues, fit/cultural concerns. The employer does not need to provide formal written reasons for dismissal during probation (the right to written reasons under section 92 ERA 1996 applies after 2 years), but most reasonable employers provide them.
Where dismissal occurs in circumstances suggesting discrimination, automatic unfair dismissal (whistleblowing etc.), or breach of contract (no notice, no payment in lieu), employment tribunal claims may be possible even during probation. The 3-month time limit from the issue applies; specialist employment advice within the period is recommended.
References: most employers provide a basic factual reference (dates of employment, role) for ex-probationary employees. The standard practice is honest factual reference rather than negative commentary. Where references are needed for future roles, asking specifically what will be said helps the ex-employee position themselves.
Probation extension and confirmation
Some contracts permit probation extension where performance is borderline. A 3-month probation might be extended to 6 months to give more time for assessment. The extension is typically done by mutual agreement, though some contracts allow unilateral extension within defined limits.
Probation confirmation: where probation is passed, the employee moves to full contractual terms. Some contracts specify a transition (longer notice after confirmation, full benefit entitlements, specific salary review). The confirmation is normally communicated in writing.
Where probation is silent (no formal confirmation or failure decision by the end of the period), the default position under most contracts is that probation is passed automatically. The employee continues on standard terms. Some employers fail to action confirmation through oversight; the employee can ask for written confirmation.
Practical action: requesting written confirmation of probation pass at the end of the period creates a clear record. Where the employer is silent past the probation end date, asking directly typically produces confirmation without difficulty.
Right to return after parental leave during probation
An employee who becomes pregnant during probation has the same statutory maternity rights as any other employee. The contract may permit the employer to delay or extend probation but cannot remove the right to take maternity leave.
Statutory Maternity Leave is 52 weeks (26 weeks Ordinary Maternity Leave + 26 weeks Additional Maternity Leave). Statutory Maternity Pay (SMP) is 6 weeks at 90% of average earnings + 33 weeks at GBP 184.03/week (2024/25). Eligibility for SMP requires 26 weeks of continuous service at the qualifying week (15 weeks before the expected week of childbirth).
Where probation is incomplete at the start of maternity leave, the typical approach is to suspend probation during the leave and resume on return. The probation completion date shifts by the length of leave taken. Where there are performance concerns pre-leave, the employer should address these before leave starts; using leave-related absence as a basis for dismissal is automatically unfair under section 99 ERA 1996.
Practical action: pregnancy or planned parental leave during probation should be communicated honestly. Some employers may extend probation post-return to allow sufficient assessment time. The employee's rights are protected regardless; the practical conversation is about how the assessment timeline accommodates the leave.

Frequently asked questions
How long is a UK probation period?
Entirely contractual - no statutory limit. Typical durations: 3 months for entry-level roles, 6 months for mid-level, 6-12 months for senior or skilled positions. Some specialist roles (medical, financial advisor) have 12-month or longer probationary periods reflecting the time needed to assess competence. The contract specifies the duration.
What employment rights do I have during probation?
Most statutory rights apply from day one: anti-discrimination, itemised payslip, minimum wage, holiday accrual, pension auto-enrolment, SSP, working time protections, automatically unfair dismissal protection. Unfair dismissal protection requires 2 years of service in most cases (proposed changes to make this a day-one right are pending). Notice during probation is typically shorter than post-probation notice.
Can I be dismissed without warning during probation?
With contractual notice yes (typically 1 week during probation). Most reasonable employers conduct review meetings and provide some opportunity for improvement before dismissal, but it is not a statutory requirement during the 2-year unfair dismissal qualifying period. Automatically unfair reasons (whistleblowing, pregnancy-related, etc.) and discrimination protect from day one regardless of probation.
Can probation be extended?
Sometimes, depending on contract terms. Some contracts permit unilateral extension within defined limits (e.g. 'probation may be extended by up to 3 months at the employer's discretion'). Others require mutual agreement. The extension is typically used where performance is borderline and more time is needed for assessment. Communication in writing of the extension reasons and timeline is the typical practice.
Do I get holiday during probation?
Yes. Holiday accrues from day one of employment under the Working Time Regulations 1998. The accrual is pro-rata based on time served. A 3-month probation gives 3/12 of the annual entitlement (around 7 days for a 28-day full-year entitlement). Most employers allow holiday to be taken during probation, though some restrict to ensure performance assessment can complete.
