The right to work compliance framework facing UK employers changed materially on 6 March 2026, when the Home Office updated its sponsor guidance to extend checking obligations beyond sponsored workers. Enforcement activity by the Home Office has intensified; legislative changes are already in effect or fast approaching, and UK employers who have not reviewed their compliance frameworks are operating in genuinely hazardous territory.
The stakes are no longer limited to civil penalties. Sponsor licence revocation, reputational damage, and criminal liability are all live risks for businesses that fall behind the pace of regulatory change.
What follows sets out where the law stands now, what changes on 1 October 2026, and how to build a compliance framework capable of absorbing both.
Why 2026 Is the Inflection Point for Right to Work Compliance
For years, the right to work framework was relatively straightforward:
- Hiring employees
- Employers checked employees before they started work
- Retained the evidence
- Repeated checks when time-limited permission was about to expire
That framework has been fundamentally altered. Three separate pressures converge to make 2026 uniquely consequential, including obligations already in force and actively enforced; new statutory duties taking effect on 1 October 2026; and updated Home Office guidance that has, in certain respects, moved ahead of the legislation itself. Employers who treat right to work compliance as a once-a-year audit exercise rather than a continuous operational discipline are particularly exposed.
Organisations that act now can build systems capable of absorbing the October changes without crisis-level disruption.
Phase One: What Is Already in Force
Many employers and HR professionals are unaware that significant changes to sponsor obligations are already live. This is a current exposure, not a future one.
The Expansion of Paragraph S1.40 to All Directly Engaged Workers
On 6 March 2026, the Home Office updated its sponsor guidance to extend the right to work checking duty beyond sponsored workers, inserting new language into paragraph S1.40 of the Part 2 of sponsor guidance. The change took effect immediately and without a transition period. The key provision requires sponsors to check that any worker they wish to employ or engage has permission to enter or stay in the UK and can do the work in question before they start working.
Previously, sponsors had to establish a statutory excuse for their employees and retain evidence of right to work checks for sponsored workers who were not direct employees. They were not, however, expected to extend checks to contractors or other workers who were neither employed nor sponsored. That exemption has now been removed for directly engaged workers.
A further clarification issued on 8 April 2026 added the qualifier “directly” before “engage” in the guidance. This was intended to address legitimate concerns that an unqualified duty to check all engaged workers could produce absurd outcomes, such as requiring a business to verify the immigration status of a courier delivering a parcel or a self-employed electrician attending for a one-off repair. This clarification narrows the obligation to direct engagement, though the term ‘directly engage’ remains undefined in the guidance itself.
The categories of workers that sponsors should now be checking include partners and members of limited liability partnerships, self-employed contractors directly engaged to perform work forming part of the normal day-to-day business activities of any UK entity covered by the sponsor licence, and non-employee zero-hours workers contracted by any UK entity covered by the licence but who are not employed under a standard employment contract.
This is not a future obligation. Sponsors who have not already audited and extended their right to work checking processes to cover these categories are currently in breach of their sponsor duties.
Phase Two: What Is Coming on 1 October 2026
On 15 April 2026, the Home Office opened a consultation on a draft Code of Practice for employers on avoiding unlawful discrimination while preventing illegal working. The draft Code states explicitly that it applies to all employment commencing on or after 1 October 2026, as well as to repeat checks on an existing worker where these must be carried out on or after that date to retain a statutory excuse. The publication of this consultation is the strongest official signal yet that the Home Office intends to implement the expanded illegal working regime by 1 October 2026.
The expanded definition of “employer” in the draft Code encompasses individuals employed under a contract of employment, under a worker’s contract, as an individual subcontractor, or via an online matching service. When this comes fully into force, the statutory obligation to carry out right to work checks will extend to gig economy platforms, umbrella company workers, personal service company contractors, and secondees, in addition to traditional employees and sponsored workers.
What Remains Uncertain
The primary legislation giving statutory effect to these changes has not yet been fully brought into force as of April 2026. The consultation on the draft Code closes on 29 April 2026 and the final Code may yet be revised. Implementation dates, while strongly signalled, are not yet confirmed in statute.
Employers should plan for a 1 October 2026 effective date while monitoring the Home Office Employer’s Guide to Right to Work Checks for updates, as this remains the operative document for compliance purposes.
The Operational Challenge for High-Volume and Flexible Workforces
The expansion of right to work obligations to cover worker contracts, individual subcontractors, and online platform arrangements creates substantial operational difficulties for many organisations, particularly those with high contractor usage or complex labour supply chains.
Scale and Complexity at Volume
Consider an organisation with several hundred self-employed contractors working on client sites at any one time. Under the new framework, each of those individuals will require a compliant right to work check before they commence work. For organisations that historically conducted checks only on payrolled employees, the administrative volume of this change should not be underestimated. Diarising repeat checks, managing eVisa expiry notifications, and maintaining audit-ready records across a non-employed population requires infrastructure that most HR teams do not currently have.
Platform Workers and the Gig Economy
The inclusion of online matching services within the expanded definition creates particular complexity. An employer that sources skilled professionals through a platform may find itself obligated to conduct right to work checks on individuals whose contractual relationship is primarily with the platform, not the end client. The precise scope of this obligation awaits final guidance, but compliance leads should begin mapping all categories of individuals providing services to their organisation, irrespective of the contractual structure.
Secondees and Supply Chain Workers
Secondees from overseas parent companies, workers supplied by staffing agencies, and subcontractors engaged further down a supply chain all present distinct compliance questions. Organisations should review existing contracts with agencies and suppliers to assess whether right to work warranties and indemnity clauses are appropriately placed and adequately drafted.
How the New Revocation Grounds Change the Risk Calculus
The most significant and underappreciated shift in 2026 relates not to who must be checked, but to what happens when things go wrong. The revised sponsor guidance has expanded the grounds on which the Home Office will normally revoke a sponsor licence, and the implications are considerable.
Revocation Even Where Correct Processes Are Followed
The revised guidance now states that if a sponsor is issued with a civil penalty, or otherwise fails to carry out the correct checks, the Home Office will normally revoke the licence. The phrase ‘or otherwise fails to carry out the correct checks’ is new and significant. It means that a civil penalty issued in connection with an expanded group of workers, including non-employees who were not previously within scope, can now trigger licence revocation.
For businesses that rely on their sponsor licence to hire international talent, the reputational and operational consequences of revocation are severe. Licence holders should treat this as a material business risk and conduct an urgent gap analysis of their current right to work checking practices against the expanded S1.40 obligations. Boards and senior leadership teams should be briefed accordingly.
Building a Scalable Compliance Infrastructure
The scale and complexity of the changes ahead mean that reactive, manual compliance processes are no longer viable for most organisations. Building a scalable infrastructure requires action across several interconnected areas.
- Identity Document Verification Technology (IDVT)
The expanded regime formally recognises Digital Verification Services as a prescribed method for conducting right to work checks. The Home Office has introduced a register of certified DVS providers, and the draft Code of Practice places new obligations on both employers and DVS providers to have systems that do not introduce or perpetuate discriminatory outcomes. Organisations that have not yet evaluated a DVS provider should do so as part of their pre-October preparation, particularly where they manage high volumes of onboarding across multiple sites or operate in sectors with frequent workforce turnover.
- Automated Diarising and Expiry Management
Time-limited right to work permissions require follow-up checks. Across a large, mixed workforce of employees, sponsored workers, self-employed contractors, and zero-hours workers, managing check expiry dates manually creates an unacceptable operational risk. Investing in automated diarising and workforce management systems that flag upcoming expirations is a necessity under the new framework, not a discretionary improvement.
- Policy Updates and Supply Chain Contractual Protections
Right to work policies must be updated to reflect the expanded scope of checking obligations. Existing contracts with agencies, labour suppliers, and subcontractors should be reviewed to ensure they contain appropriate warranties that all workers supplied have a right to work in the UK, along with indemnity provisions in the event of a breach. These contractual protections do not substitute for conducting checks directly, but they are important risk-allocation tools.
- Training for Hiring Managers
Front-line hiring managers are often the individuals who conduct or supervise right to work checks. Under the expanded regime, they will be dealing with a wider and more varied population of workers. The draft Code of Practice explicitly reinforces the obligation to treat all applicants fairly at each stage of the recruitment process, including when carrying out right to work checks. Training programmes should be updated and delivered before October 2026 to ensure consistent, non-discriminatory practices across all worker categories.
A Phased Action Plan: Now, by July, and by October 2026
Immediate Actions (April to May 2026)
The S1.40 expansion is already in force. Employers should conduct a comprehensive audit of right to work documentation across their entire directly engaged workforce. Where gaps are identified and the individual remains employed, reverification should be completed immediately and documented carefully. HR and legal teams should be briefed on the expanded obligations and empowered to escalate concerns without delay.
Actions by July 2026
By July 2026, employers should have completed their evaluation and selection of IDVT providers, updated their standard employment and contractor agreements to include right to work warranties and audit rights, and implemented automated diarising functionality in their HR systems. A training cycle for all hiring managers and HR business partners should also be under way. Organisations with complex supply chains should by this point have mapped their contractor and subcontractor population and opened conversations with suppliers about compliance expectations.
Actions by October 2026
The final weeks before 1 October 2026 should not be spent in frantic preparation. If the earlier phases have been executed well, October marks the operational go-live of an already-tested infrastructure. The focus in the final phase should be on stress-testing systems, conducting a tabletop exercise simulating a Home Office inspection, updating board-level reporting to include right to work compliance as a standing agenda item, and confirming that supply chain audit mechanisms are operational.
Conclusion
The 2026 right to work reforms represent a genuine step change in the obligations facing UK employers, not an incremental adjustment. The combination of expanded sponsor duties already in force, the October extension to worker and contractor populations, new revocation grounds that remove the protection previously offered by good-faith compliance, and an enforcement environment more active than at any recent point creates a risk profile that demands strategic rather than administrative responses.
Organisations that approach right to work compliance as a one-time onboarding task will find themselves exposed to enforcement action, financial penalties, and sponsor licence revocation in the months ahead. Those that invest in scalable infrastructure, trained personnel, and robust contractual protections will be positioned not merely to absorb the 2026 reforms but to turn compliance strength into a competitive differentiator, when bidding for contracts, attracting global talent, and demonstrating regulatory maturity to clients and investors.
Organisations that start now will be building on solid ground by October; those that wait will be scrambling to catch up.
