Shared Parental Leave UK — Employer Rights Obligations and How It Differs from Maternity Leave
Why Trust This Assignment?
- AC 2.1For a side-by-side statutory comparison of ShPL against maternity leave in the context of the CIPD 5OS01 unit, the [maternity leave vs shared parental leave](/5os01-maternity-vs-shared-parental-leave/) page covers theassessment criterion with specific statutory values for both leave types.
Shared Parental Leave (ShPL) is a statutory entitlement introduced by the Work and Families Act 2006 and detailed in the Shared Parental Leave Regulations 2014, allowing eligible parents to share up to 50 weeks of leave and up to 37 weeks of Statutory Shared Parental Pay in the first year after a child’s birth or adoption. ShPL is not an extension of maternity leave. It is a separate, distinct entitlement that can only be activated when the mother or primary adopter curtails their maternity leave through a formal curtailment notice and both parents independently satisfy their own eligibility criteria. Available for babies born or adopted on or after 5 April 2015, ShPL represents the UK’s primary legislative mechanism for enabling flexible, shared childcare between two parents in the first year of a child’s life.
What Is Shared Parental Leave? — Definition and Legislative Basis
Shared Parental Leave allows eligible parents to share up to 50 weeks of leave between them following the birth or adoption of a child, under the Shared Parental Leave Regulations 2014 made pursuant to the Work and Families Act 2006. The 50 weeks figure derives from the total 52-week parental leave entitlement minus the 2 weeks of compulsory maternity leave that the mother must take immediately following birth — a period that cannot be shared.
The purpose of ShPL is to shift the UK parenting model away from the assumption that the mother will take all or most of the available leave. ShPL gives both parents the legal means to divide the available leave period in whatever pattern suits their family circumstances, including taking leave simultaneously. Eligibility requires both parents to meet separate criteria — ShPL cannot be taken unilaterally by one parent.
One structural feature distinguishes ShPL from maternity leave at the outset: ShPL cannot begin for either parent until the mother or primary adopter has submitted a curtailment notice. The curtailment notice is the procedural trigger that converts unspent maternity leave into the ShPL pool. Without it, no ShPL entitlement is accessible regardless of whether both parents meet their eligibility conditions.
For a side-by-side statutory comparison of ShPL against maternity leave in the context of the CIPD 5OS01 unit, the maternity leave vs shared parental leave page covers the AC 2.1 assessment criterion with specific statutory values for both leave types.
Take-up of ShPL by eligible fathers and partners has remained consistently below 5% since the regime launched in 2015 (CIPD, 2022). The primary deterrent is financial: Statutory Shared Parental Pay pays at a flat rate throughout, while Statutory Maternity Pay includes an enhanced 90% of average weekly earnings period in the first 6 weeks. This financial asymmetry is the central practical limitation on ShPL’s stated objective of enabling gender-neutral shared parenting.
Shared Parental Leave Eligibility — Two Separate Tests
Shared Parental Leave requires both parents to satisfy separate eligibility tests with their own respective employers. If either parent fails their test, neither parent can access ShPL. The dual-test structure is the most significant complexity distinction between ShPL and maternity leave, which requires only a single eligibility check.
The two eligibility tests operate independently. Each parent applies through their own employer. Both tests must be satisfied at the same time for ShPL to be available to either parent. An employer managing a ShPL request must verify their own employee’s eligibility and receive satisfactory written confirmation from that employee about the other parent’s eligibility status — even though the other parent’s employer is separately responsible for assessing that parent.
The Mother’s Eligibility Test
The mother’s eligibility test requires three conditions to be met simultaneously. First, the mother must be entitled to statutory maternity leave — which requires employee status and 26 weeks of continuous service with the same employer by the 15th week before the Expected Week of Childbirth — or entitled to Statutory Maternity Pay (or Maternity Allowance if SMP does not apply). Second, she must share caring responsibility for the child with her partner. Third, and critically, she must submit a curtailment notice to her employer specifying the date on which her maternity leave will end.
The curtailment notice is the activation trigger for ShPL. Many HR practitioners incorrectly assume that ShPL begins automatically when maternity leave ends or when the mother returns to work. This assumption is wrong. ShPL requires a formal curtailment notice, submitted in advance, naming the curtailment date. Without it, neither parent has access to ShPL regardless of eligibility. Once the partner has begun taking ShPL, the curtailment notice becomes binding and cannot be revoked. The mother cannot revert to maternity leave after curtailment has been activated by the partner’s ShPL start. The only exception is if the partner loses their eligibility before they actually begin their ShPL period — in that narrow circumstance, the curtailment notice can be revoked.
The Partner’s Eligibility Test
The partner’s eligibility test requires three independent conditions. First, the partner must have been employed by the same employer for at least 26 continuous weeks by the 15th week before the Expected Week of Childbirth. Second, the partner must earn at or above the Lower Earnings Limit of £123 per week (2024/25 rate, subject to annual uprating). Third, the partner must be living with the child and the mother at the time they take ShPL.
In addition to satisfying their own employer’s eligibility requirements, the partner must provide their employer with a written declaration from the mother confirming that she has curtailed (or intends to curtail) her maternity leave and agrees to share the remaining entitlement. This cross-employer documentation requirement adds an administrative step that has no equivalent in the maternity leave eligibility process. HR practitioners must build the receipt and retention of this declaration into their ShPL administration process.
Self-employed partners face specific complexity: a self-employed partner may still access ShPL if they satisfy the equivalent conditions under the Statutory Shared Parental Pay (General) Regulations 2014, including meeting the maternity allowance or SMP equivalent conditions. Agency workers face additional complexity around the continuity of employment test where assignment patterns are irregular.
How Many Weeks of Shared Parental Leave Are Available?
Up to 50 weeks of ShPL are available to share between both parents, calculated as the total 52-week parental leave entitlement minus the 2 weeks of compulsory maternity leave that must be taken by the mother immediately following birth. Those 2 compulsory weeks are not transferable. They are the mother’s alone, they cannot be converted into ShPL, and they reduce the maximum available ShPL pot from 52 weeks to 50.
Of those 50 weeks, up to 37 weeks carry an entitlement to Statutory Shared Parental Pay — because SMP runs for 39 weeks, and the 2 weeks of compulsory maternity leave already account for 2 of those 39 SMP weeks, leaving 37 weeks of ShPP available within the 50-week ShPL period.
For a comparison with the maternity leave entitlement structure — covering the Ordinary Maternity Leave and Additional Maternity Leave phases and their return-to-work implications — the maternity leave UK employer guide sets out the full employer obligations during each phase.
Sequential use is where parents take ShPL in non-overlapping blocks: one parent takes their leave first, then the other takes theirs. The pot depletes at 1 week per calendar week taken. Total elapsed calendar time may reach 50 weeks if parents take their leave back to back.
Concurrent use is where both parents take ShPL at the same time. Concurrent use depletes the pot faster: 4 weeks of concurrent leave by both parents consumes 8 weeks from the available total, because both parents are simultaneously drawing from the shared 50-week entitlement. Concurrent use reduces the total elapsed calendar period of leave coverage but gives both parents the experience of joint full-time childcare during the concurrent period.
For adoption: ShPL is also available where a child is adopted. The same 50-week pot applies, calculated from the date of placement. The primary adopter must curtail their adoption leave (the adoption equivalent of maternity leave) through a curtailment notice to activate ShPL for either adoptive parent. The mechanics are equivalent to birth-related ShPL.
Statutory Shared Parental Pay — Rate and Comparison with SMP
Statutory Shared Parental Pay pays £184.03 per week (2024/25 rate, subject to annual uprating each April) as a flat rate throughout the entire ShPP entitlement period, or 90% of average weekly earnings if that figure is lower. There is no enhanced payment in the first weeks of ShPP. The flat rate applies from the first week, with no escalating scale.
This contrasts sharply with Statutory Maternity Pay, which pays 90% of average weekly earnings (AWE) for weeks 1 to 6 with no upper ceiling, then drops to the flat rate of £184.03 per week (2024/25) for weeks 7 to 39. For an employee earning £35,000 per year — an AWE of approximately £673 per week — SMP in weeks 1 to 6 pays approximately £605 per week. ShPP in week 1 pays £184.03. The weekly financial gap is approximately £421. Across the first 6 weeks, the household income loss from the partner taking ShPL instead of the mother continuing on SMP is approximately £2,526.
This financial gap directly explains why CIPD (2022) research consistently finds fewer than 5% of eligible fathers and partners take Shared Parental Leave. Where the partner earns less than the mother — which remains the more common pattern in UK households — the family unit loses less income by keeping the mother on SMP and the partner at their full salary than by transferring leave to the partner and accepting ShPP in place of SMP. The financial structure of ShPP was designed to make the entitlement available, but not to remove the financial disincentive for the partner to take it.
The statutory basis for ShPP is the Statutory Shared Parental Pay (General) Regulations 2014. ShPP is recoverable by employers from HMRC in the same way as SMP: small employers (total employer NIC liability below £45,000 annually) can recover 103% of ShPP paid (including a 3% compensation for employer NIC costs); larger employers can recover 92%.
How to Take Shared Parental Leave — Blocks, Notice and the Curtailment Process
Shared Parental Leave activates only when the mother or primary adopter submits a curtailment notice to their employer specifying the date on which they will end their maternity leave. Until the curtailment notice is submitted, no ShPL entitlement exists for either parent. This is the single most important administrative point for HR practitioners to understand, because the assumption that ShPL flows automatically from maternity leave ending is incorrect.
Once the curtailment notice is submitted, the partner may then submit a block notice to their own employer requesting a period of ShPL, subject to meeting the 8-week advance notice requirement. The curtailment notice and the block notice are two separate documents, submitted to two separate employers.
Block booking notice requirements. Each block of ShPL requires at least 8 weeks’ advance written notice from the employee. The notice must state the start date, end date, and whether the employee is requesting Statutory Shared Parental Pay during the block. The employer has 2 weeks from receipt of the notice to respond. Up to 3 separate block booking notices are permitted under the Shared Parental Leave Regulations 2014 for each parent individually — not 3 combined across both parents.
Discontinuous block requests. An employee may request a discontinuous pattern — for example, 4 weeks of leave followed by 4 weeks of work followed by 4 weeks of leave — within a single block notice. An employer may agree to this pattern, negotiate an alternative, or refuse. If the employer refuses a discontinuous pattern and no agreement is reached within 2 weeks of the notice, the employee may withdraw the notice altogether or elect to take the leave as a continuous block instead. The employer cannot require the employee to abandon their ShPL entitlement on refusal of a discontinuous pattern — they must offer the continuous alternative.
Shared Parental Leave In Touch (SPLIT) days. During ShPL, up to 20 SPLIT days are permitted per employee. SPLIT days are days worked during the leave period by agreement with the employer. They do not end the leave period and do not extend the total entitlement. Each SPLIT day worked allows the employee to receive their normal pay for that day rather than ShPP, which may assist both the employee and the employer where the business has a temporary need for that employee’s skills. SPLIT days must be agreed — the employer cannot require SPLIT days and the employee cannot take them unilaterally.
For a full worked example of how the ShPL framework appears in a CIPD Level 5 assignment, the CIPD 5OS01 specialist employment law page applies these procedural elements to the AC 2.1 assessment criterion.
How Does Shared Parental Leave Compare to Maternity Leave for HR Planning?
ShPL generates significantly greater administrative complexity per leave episode than maternity leave. Maternity leave is triggered by a single eligibility check and a single notification at 15 weeks before the Expected Week of Childbirth. ShPL can generate dual eligibility verifications, a curtailment notice, up to 3 block notices per parent, employer responses, SPLIT day records, and multiple payroll adjustments across a leave episode that may span the better part of a year in non-consecutive blocks. HR teams that design their parental leave procedures around the maternity leave model will find those procedures inadequate for managing ShPL requests. Pay policy design adds a further dimension: where an employer enhances SMP, the equality law obligation to consider equivalent ShPP enhancement requires active HR policy decision-making rather than passive acceptance of the statutory default.
HR Administration Responsibilities for Shared Parental Leave
HR teams managing ShPL must operate a distinct administrative process from their maternity leave process. The volume of documentation per ShPL episode significantly exceeds that for maternity leave, and the multi-employer dimension — where the partner’s curtailment documentation originates from the mother’s employer — adds a cross-organisational coordination step.
For the equivalent employer obligations during maternity leave, including KIT day management, risk assessments during pregnancy, and suitable alternative employment obligations, the maternity leave UK employer guide covers the full maternity administration process.
The ShPL Administration Timeline
The HR administration sequence for a ShPL request follows seven steps per leave episode. Step one: receive the mother’s curtailment notice and record the curtailment date. Step two: issue written confirmation to the mother that her maternity leave has been curtailed and notify payroll to cease SMP from the curtailment date. Step three: receive the partner’s ShPL block notice at least 8 weeks before the intended start date. Step four: respond within 2 weeks — agree the block as requested, negotiate an alternative, or refuse a discontinuous pattern and offer a continuous alternative. Step five: calculate and administer ShPP for the block period, applying HMRC recovery rules. Step six: manage any SPLIT day requests during the block, confirming each by written agreement and adjusting pay accordingly. Step seven: process the return to work at the end of the block, confirming the right to return (same job or suitable alternative, depending on total leave duration).
HR must repeat steps three through seven for each of the up to 3 blocks an employee may request. A parent who takes 3 non-consecutive blocks generates 3 separate 8-week notice cycles, 3 employer response decisions, and 3 ShPP payroll adjustment sequences. Maintaining accurate records of each cycle is essential because eligibility to a specific return-to-work protection depends on the total duration of leave across all blocks.
Enhanced ShPP — The Equality Act Obligation
An employer who enhances Statutory Maternity Pay above the statutory rate — for example, by paying full salary for the first 16 weeks — faces an obligation to consider whether its ShPP policy is equivalent. Failure to offer equivalent ShPP enhancement where SMP is enhanced may constitute indirect sex discrimination under Equality Act 2010 s.19. The legal argument is that a provision, criterion, or practice that requires employees to take maternity leave (rather than ShPL) to access enhanced pay places male partners at a particular disadvantage, because male partners can only access parental leave through ShPL, not maternity leave.
The legal position remains contested. The Employment Appeal Tribunal considered related issues in Capita Hartshead Ltd v Duckworth [EAT 2016], where the employer’s enhanced maternity pay policy was found not to require identical enhancement to ShPP in all respects, but the decision turned on specific facts. The broader legal risk remains real, and the legal position has continued to develop since 2016. ACAS recommends that employers who enhance SMP review their ShPP policy to ensure the overall package does not systematically disadvantage male partners.
For a statutory comparison of SMP and ShPP rates in the context of the CIPD 5OS01 AC 2.1 assessment criterion, the maternity leave vs shared parental leave page provides the comparative analysis with specific 2024/25 pay figures.
What Employers Should Know About Enhanced ShPP
The practical test for enhanced ShPP equality risk is proportionality under Equality Act 2010 s.19. The employer must be able to show that any differential treatment (offering enhanced SMP but not enhanced ShPP) is a proportionate means of achieving a legitimate aim. The legitimate aim most commonly relied on is supporting pregnant employees and new mothers through the biological and physiological demands of pregnancy and early motherhood — a purpose that is sex-specific and cannot apply to partners. However, the proportionality assessment becomes more complex where the enhanced pay period extends well beyond the immediate post-birth recovery period into months 3 to 6 of leave, where the physiological rationale weakens. ACAS guidance recommends reviewing enhanced SMP policies on a rolling basis and considering whether enhancement should be extended to ShPP at least for equivalent periods beyond the compulsory maternity leave phase.
Shared Parental Leave in CIPD Assignments — Which Modules Cover This
Shared Parental Leave appears as a substantive topic in the CIPD Level 5 Associate Diploma in People Management, specifically within the 5OS01 Specialist Employment Law unit. Assessment criterion AC 2.1 requires students to explain the differences between maternity leave and Shared Parental Leave — making this employer guide directly relevant to students preparing their 5OS01 assignment answers. The statutory values on this page (50-week pot, £184.03/week ShPP rate, 8-week notice per block, 2-week employer response window) are the specific figures required to support an AC 2.1 answer at distinction level.

Frequently Asked Questions — Shared Parental Leave UK
Can a mother return to maternity leave after curtailing it for Shared Parental Leave?
No. Under the Shared Parental Leave Regulations 2014, once a mother has submitted a curtailment notice and the partner has begun taking Shared Parental Leave, the curtailment notice becomes binding and cannot be revoked. The mother’s maternity leave ends on the curtailment date. She cannot revert to maternity leave after that point. The one exception is where the partner has not yet started their ShPL: if the partner loses their eligibility before commencing ShPL, the curtailment notice can be revoked and the mother can resume maternity leave. Employers should confirm the partner’s eligibility status before processing a curtailment notice to avoid inadvertently activating this irrevocability.
Do both parents have to work for the same employer to take Shared Parental Leave?
No. Each parent satisfies their own eligibility test with their own employer, independently. The mother applies for ShPL through her employer; the partner applies through their employer. Both parents can work for entirely different organisations. The only cross-employer documentation is the written declaration from the mother confirming she has curtailed her maternity leave, which the partner provides to their own employer as part of the partner’s eligibility evidence. The two ShPL applications are processed entirely separately by separate employers — there is no joint application mechanism and no requirement for employer coordination beyond the documentation exchange.
What is the notice period for Shared Parental Leave?
Each block of Shared Parental Leave requires at least 8 weeks’ advance written notice to the employee’s employer. Under the Shared Parental Leave Regulations 2014, a parent may submit up to 3 separate block booking notices across the total ShPL entitlement. Each notice must state the start date, end date, and whether ShPP is requested during the block. The employer has 2 weeks from receipt of the notice to respond — agreeing to the request, negotiating an alternative, or refusing a discontinuous pattern and offering a continuous block instead. This notice structure contrasts with maternity leave, which requires a single notification at 15 weeks before the Expected Week of Childbirth with no further notice cycles.
Can Shared Parental Leave be taken at the same time by both parents?
Yes. Both parents can take Shared Parental Leave simultaneously — concurrent use is one of the structural flexibilities that distinguishes ShPL from maternity leave, which is exclusive to the mother. When both parents take ShPL at the same time, both draw from the shared 50-week pot simultaneously. Four weeks of concurrent leave by both parents consumes 8 weeks from the available total. Parents choosing concurrent use should plan the total pot consumption carefully: if both parents take 8 weeks concurrently, 16 weeks are consumed from the 50-week pot, leaving 34 weeks for the remaining sequential leave period. Each parent must submit their own 8-week advance notice to their respective employers independently.
