Six weeks’ paid paternity leave could add £2.68bn a year to UK economy, report finds

The Economic Case for Reform

The report, titled Economic and Social Benefits of Enhanced Paternity Leave: Scoping Review, suggests that the current statutory provision for fathers is insufficient to drive meaningful societal or economic change. Researchers analyzed 33 studies from across Europe, Canada, and the United States to determine how "use-it-or-lose-it" paternity leave schemes influence labor market participation.

The central recommendation is the implementation of at least six weeks of leave for fathers and non-birthing parents, compensated at 90 percent of average weekly earnings. Crucially, the researchers emphasize that this entitlement must be non-transferable. By reserving this leave for the father, the policy prevents the "transfer" of time to the mother, which often occurs under current systems and reinforces traditional gender roles that view childcare as an exclusively maternal responsibility.

Economically, the gains are projected to be significant. While the direct cost of paying fathers during their leave is estimated at £2.8 billion, the long-term multiplier effects—driven by higher female labor force participation and increased hours for working mothers—are estimated to generate £5.5 billion in output. This yields a net annual economic gain of £2.68 billion, a figure that provides a compelling argument for policymakers currently reviewing the UK’s broader employment landscape.

A Chronology of Paternity Leave in the UK

To understand the current urgency of these recommendations, one must look at the evolution of paternity rights in Britain. Historically, paternity leave was virtually non-existent, with the burden of care falling almost exclusively on mothers.

• 2003: The UK introduced the first statutory right to paid paternity leave, allowing eligible fathers two weeks of leave at a relatively low flat rate.
• 2015: The government implemented Shared Parental Leave (SPL), a policy intended to provide flexibility. However, uptake has remained notoriously low, with estimates suggesting that fewer than 5 percent of eligible couples take advantage of it. The complexity of the system and the financial loss incurred by families when a higher-earning father takes leave are often cited as the primary barriers.
• April 2024: Paternity leave became a "day-one" employment right, removing the requirement for long-term service before a father can request time off. While this was a positive step for labor rights, the fundamental issues of low pay and short duration remain unresolved.
• Present Day: The UK government is currently conducting a comprehensive review of the entire parental leave and pay system, including maternity and paternity provisions. This review is expected to culminate in a formal roadmap for structural reform.

Global Evidence and Lessons from Abroad

The report draws heavily on the "Quebec model" and other international success stories. In 2006, Quebec introduced five weeks of paternity leave at 70 percent of earnings. The impact was near-immediate: the take-up rate among fathers skyrocketed, and subsequent studies demonstrated a lasting shift in the domestic division of labor. Fathers who participated in the program were found to be more involved in day-to-day childcare and household management years after their leave concluded.

Similar trends were observed in Germany, where the implementation of "daddy quotas" led to higher rates of maternal return-to-work. Employers in these jurisdictions reported lower turnover rates, as mothers were more likely to return to their original firms following a period of balanced parental leave. This suggests that the "motherhood penalty"—a well-documented phenomenon where women see their earnings and career progression decline following the birth of a child—can be effectively mitigated through policies that normalize paternal involvement.

Strengthening the Family Unit

One of the most striking findings in the King’s College London research relates to the stability of the family unit. The study highlights data from Iceland, where the introduction of a dedicated month of paternity leave was associated with an 11.6 percentage point reduction in parental separation after five years, and an 8.9 point reduction after 15 years.

While the researchers advise caution in treating these results as a universal guarantee, the correlation is statistically significant. The report estimates that if similar trends were to materialize in the UK, the reduction in family breakdown could result in an economic benefit of approximately £599 million. This underscores the argument that family-friendly policies are not merely a matter of social welfare; they are essential infrastructure for a stable and productive economy.

Addressing the "Affordability" Gap

Professor Heejung Chung, director of the Global Institute for Women’s Leadership, emphasizes that paternity leave is frequently mischaracterized as a budgetary drain. "Paternity leave is still too often treated simply as a bill for government and employers," Professor Chung noted. "But the strongest evidence shows that when fathers have leave of their own and can afford to take it, they do more care at home and mothers are better able to stay in paid work, which benefits the country economically."

The report’s co-author, Shiyu Yuan, argues that the current UK statutory rate of £194.32 per week is essentially a deterrent for many families. "A few extra weeks that families cannot afford will not deliver the economic and social gains so many other countries have seen," Yuan stated. The researchers argue that for the policy to be successful, it must be inclusive, extending beyond traditional full-time employees to reach those in the gig economy, zero-hours contract roles, and the self-employed.

Implications for Employers and Small Businesses

While the proposal represents a significant change for the business community, the report suggests that the long-term benefits may outweigh the immediate adjustment costs. For employers, the primary advantage is retention. By fostering a culture where both parents share the responsibility of care, companies can reduce the loss of talent associated with women leaving the workforce during their child-rearing years.

To support this transition, the researchers recommend that any reform package include comprehensive guidance for employers and, crucially, financial support or tax incentives for smaller businesses that may struggle to cover the temporary absence of staff. By alleviating the administrative and financial burden on smaller firms, the government could ensure that the policy remains equitable across all sectors of the economy.

The Path Forward: A Call for Structural Change

The current UK review of parental leave presents a rare window for legislative intervention. As the government evaluates how to balance the needs of working families with the broader requirements of the national economy, the evidence from the King’s College London report provides a clear blueprint.

The distinction between "transferable" and "non-transferable" leave is perhaps the most important technical detail in this proposal. By making the six weeks of leave non-transferable, the government would be sending a clear signal that the state expects and encourages fathers to be primary caregivers. This shift in social norms is the final piece of the puzzle that the UK has been missing for decades.

As the debate continues, policymakers will be forced to weigh the upfront fiscal costs against the long-term gains in labor market productivity, reduced social service strain, and increased family stability. While the researchers acknowledge that international data serves as a guide rather than a precise forecast for Britain, the consistency of the findings across diverse economies like Germany, Canada, and Iceland suggests that the proposed model is not only viable but necessary for a modern, inclusive, and competitive British economy.

Ultimately, the goal of such a reform is to move beyond the antiquated view of paternity leave as a "perk" and recognize it as a fundamental economic investment. By empowering fathers to participate fully in the early stages of parenthood, the UK has the potential to unlock billions in economic output while simultaneously fostering a more equitable and stable society. The ball is now firmly in the court of the government as it works to finalize its long-awaited roadmap for the future of British working families.
