The UK government’s Immigration and Asylum Bill introduces major changes to how businesses must report on modern slavery, converting a long-standing voluntary requirement into a legally enforced duty. Currently, companies with annual revenues of at least £36 million operating in the UK must publish yearly statements on their efforts to combat exploitation within supply chains. This rule, established in 2015, has promoted transparency but faced criticism for lacking enforcement mechanisms. Without penalties for non-compliance, many firms produced superficial statements that offered little practical detail.
Flaws in the existing framework
The current system demands that statements be approved by a company’s board, signed by a director, and displayed prominently on the corporate website. While some organizations provide thorough risk evaluations and audit results, others simply restate existing policies without addressing actual vulnerabilities in supplier relationships. Additionally, public sector entities remain exempt, creating significant gaps in oversight and weakening the law’s intended impact. The primary objective—to ensure businesses actively monitor suppliers—has been undermined by these loopholes.
Critics argue the absence of consequences has turned compliance into a mere formality. Many statements remain virtually unchanged year after year, with little evidence of meaningful progress or accountability. The proposed legislation now seeks to remedy this by mandating the disclosure of specific risk assessments and due diligence outcomes, shifting focus from generic policy statements to verifiable actions.
Key changes and enforcement
The bill proposes three major reforms. First, companies will incur financial penalties for non-compliance, with fines capped at either £1 million or 1% of annual turnover, whichever is greater. Second, a public naming system will identify businesses that fail to publish required statements. Third, parent companies must verify that subsidiaries adhere to the rules, ensuring uniformity across corporate structures.
For the first time, public authorities meeting specific financial thresholds will also be required to disclose statements, eliminating a previously unaddressed exemption. While the bill does not mandate full supply chain due diligence, a demand from advocacy groups, it does require businesses to either document risk evaluations and mitigation efforts or explicitly state if no assessments were conducted. Enforcement will be stricter, with penalties now applicable for violations lacking a valid justification, a sharp contrast to the prior system where infractions went unaddressed.
The proposed changes aim to raise modern slavery statements from optional exercises to critical corporate priorities. Some observers may view the bill’s limitations as insufficient, particularly regarding supply chain scrutiny, but the shift toward mandatory compliance with real consequences represents a substantial advance. Previously, the lack of penalties allowed companies to treat the requirement as a public relations formality. That approach may no longer be viable.

The bill’s introduction to Parliament on June 30 signals the government’s commitment to reform. If enacted, the new rules will apply equally to businesses and public bodies, with penalties serving as a deterrent against superficial compliance. The challenge ahead lies in whether companies will treat these obligations as a necessary expense or as an opportunity to genuinely tackle modern slavery risks.
Adjustments for businesses
Organizations exceeding the £36 million turnover threshold must prepare for significant changes. The bill’s provisions indicate that modern slavery statements will demand more rigorous analysis, greater resource allocation, and clearer accountability. Risk assessments and mitigation strategies will need detailed documentation rather than vague references. Public sector bodies, previously excluded, will now participate in the process for the first time.
The transition from voluntary to mandatory reporting could introduce unintended effects. Smaller firms outside the current scope may adopt similar practices to remain competitive, while larger enterprises may face increased administrative burdens. However, the prior lack of penalties contributed to widespread complacency, and the new requirements may finally compel meaningful engagement. One notable detail is that the bill does not require full supplier due diligence, only the reporting of risk evaluations. This leaves interpretation open, but the introduction of penalties and public exposure could still drive action.
The government’s initiative reflects broader demands for corporate accountability regarding modern slavery. Whether these reforms deliver on expectations remains uncertain. The focus now shifts to implementation: how businesses respond to the new obligations will determine whether the law succeeds in reducing exploitation within supply chains.
Public sector bodies will soon face the same reporting obligations as private companies, closing a long-standing exemption. The bill’s passage would mark a turning point in how organizations address modern slavery, with penalties and transparency measures designed to encourage genuine progress rather than superficial compliance.
