B-Rated Sponsor Licences: Immtell's 2026 Analysis

Adult social care accounts for almost half of B-rated sponsors

Adult social care businesses account for almost half of all UK sponsors currently holding a B-rated sponsor licence, despite representing fewer than one in twenty licensed sponsors overall. This finding comes from original Immtell research using the Home Office register of licensed sponsors as at 12 November 2026, supplemented by Companies House records to identify the sectors in which businesses operate.

Our analysis identified 117 B-rated sponsors across the UK. Of those, 54 were classified as operating in adult social care. The sector therefore accounts for just 4.3% of licensed sponsors but 46.2% of those currently holding a B rating. That is approximately 10.7 times its share of the overall sponsor population, a striking imbalance given the sustained Home Office scrutiny of the sector.

Key Takeaways

• Adult social care accounts for a substantial share of B-rated sponsor licences in Immtell's 2026 analysis.
• A B-rating means the sponsor must follow a Home Office action plan to address identified compliance failures.
• The commercial impact extends beyond the action plan: recruitment and ongoing sponsorship can be affected.
• Early investigation of the underlying record-keeping, reporting and employment practices is more useful than a superficial file tidy-up.

The findings at a glance

• Total licensed sponsors analysed: 127,583
• Sponsors holding a B rating: 117
• Adult social care sponsors: 5,535
• Adult social care sponsors holding a B rating: 54
• Adult social care share of all sponsors: 4.3%
• Adult social care share of B-rated sponsors: 46.2%

Adult social care is approximately 10.7 times more represented among B-rated sponsors than its share of all licensed sponsors would suggest. The accompanying original Immtell chart compares sector representation across the sponsor population with the distribution of B ratings.

What does a B-rated sponsor licence mean?

The Home Office normally awards an A rating when it grants a sponsor licence, provided the organisation meets the relevant requirements. Where compliance failings are identified, it may downgrade an existing sponsor to a B rating rather than immediately suspending or revoking its licence. A B rating requires the sponsor to follow a Home Office action plan to address the shortcomings identified.

A B-rated sponsor generally cannot assign new Certificates of Sponsorship (CoS) until its A rating has been restored, although limited exceptions can apply for existing sponsored workers. The sponsor must also pay for the action plan and demonstrate that the necessary improvements have been implemented. Failure to comply can ultimately result in revocation. For businesses dependent on overseas recruitment, a downgrade can therefore affect workforce planning, recruitment commitments and operational continuity.

Why is adult social care so heavily represented?

The disproportionate number of B-rated sponsors in adult social care needs to be considered against the background of significant abuse of the UK's sponsorship system within the sector.

In its May 2025 immigration white paper, Restoring Control over the Immigration System, the Government acknowledged exploitation and misuse of sponsorship arrangements in adult social care, including unethical recruitment practices, exploitation of overseas workers and employers failing to comply with their sponsorship obligations. The sector has consequently faced increased scrutiny.

The seriousness of those problems should not be understated. Exploitation of migrant workers and deliberate abuse of the sponsorship system warrant robust enforcement action. However, there is an important distinction between businesses deliberately circumventing immigration rules and otherwise responsible employers making genuine administrative or procedural mistakes.

In my view, there is a legitimate question about whether the Home Office's response to widespread abuse has resulted in an overcorrection. With adult social care receiving such intense scrutiny, there is a risk that genuine, well-intentioned sponsors find themselves facing formal compliance action for shortcomings that might previously have been addressed through guidance or proportionate remedial measures.

This is particularly relevant in a sector where employers often manage complex staffing arrangements across multiple locations, with variable working hours, shift patterns and significant administrative demands. Errors in salary calculations, record-keeping or SMS reporting can occur without any intention to abuse the immigration system. That does not remove a sponsor's legal responsibilities, but the nature and seriousness of a breach should matter when determining the appropriate response.

Our findings do not establish that the Home Office is treating care providers disproportionately, nor do they reveal the reasons individual sponsors received a B rating. They do, however, raise an important question: is the current approach to enforcement sufficiently distinguishing between deliberate abuse and genuine compliance failures?

For legitimate care providers, the practical reality is that heightened scrutiny makes proactive compliance management more important than ever. Even an unintentional failure can have serious consequences for a business, its employees and the vulnerable people who depend on the services it provides.

A B rating is not the only risk

Public discussion about sponsor compliance often focuses on suspensions and revocations, which understandably attract attention because of their serious consequences for employers and sponsored workers. B-rated licences receive comparatively little attention, yet a downgrade is itself a significant regulatory intervention. It indicates that the Home Office has identified failings serious enough to require formal remedial action.

The commercial consequences can arise well before a licence is revoked. An organisation unable to sponsor new workers may struggle to fill vacancies, fulfil contracts or maintain staffing levels. There is also the cost of implementing an action plan, addressing the underlying deficiencies and demonstrating that appropriate systems are in place. For businesses operating on tight margins, particularly in adult social care, those consequences can be substantial.

What should employers take from these findings?

The central lesson is that sponsor compliance needs to be tested against what is actually happening within the business, rather than relying solely on written policies and procedures. An employer may have documented recruitment processes, right-to-work procedures and systems for monitoring visa expiry dates, but those arrangements must work in practice.

Employers should be able to reconcile sponsored workers' actual salaries and working hours with their CoS, identify changes that require SMS reporting and demonstrate that the appropriate records have been maintained. These matters should be examined proactively, rather than for the first time when the Home Office announces a compliance visit. Independent reviews can identify discrepancies and provide an opportunity to address them before they become the subject of enforcement action.

Immtell's perspective

Immtell's sponsor compliance work is led by Ewen McKenzie, Head of Sponsor Compliance and a former Home Office Regional Compliance Manager. Our approach draws on direct Home Office enforcement and compliance experience to examine how an organisation operates in practice, including sponsored worker records, salary arrangements, reporting procedures and internal controls.

Research methodology and limitations

This analysis was undertaken by Immtell using the Home Office's published register of licensed sponsors (workers) dated 12 November 2026. We identified 127,583 sponsor records, of which 117 carried a B-rating designation. To assess sector representation, we matched sponsor information against Companies House records and examined available Standard Industrial Classification (SIC) codes.

For adult social care, the classification included SIC codes 87100, 87200, 87300, 87900 and 88100. We also included a limited number of sponsors whose names clearly identified them as adult social care providers. Of the 54 B-rated sponsors classified as adult social care, 39 were identified through relevant SIC codes and 15 through unambiguous business names. This deliberately conservative classification avoids overstating the finding, although a wider interpretation of potentially care-related businesses could produce a higher figure. Some sponsors could not be reliably allocated to a sector and remain unclassified.

Important limitation: These figures are a snapshot of sponsors holding a B rating on 12 November 2026. They are not the number of sponsors downgraded during 2026 and do not establish the number of Home Office compliance visits conducted in each sector. Sector classifications reflect Immtell's analysis of available records, rather than an official Home Office sector breakdown.
