UK Court Declares Home Office's Care Worker Sponsorship Rule Unlawful: A Victory for Workers' Rights!
In a landmark ruling, the King's Bench Division (Administrative Court) has determined that the Home Office's requirement for specific contracts with guaranteed hours in Defined Certificate of Sponsorship (DCoS) applications for care workers is unlawful.

The case, R (Hartford Care Group Ltd) v Secretary of State for the Home Department [2024] EWHC 3308 (Admin), highlights the importance of employing overseas workers in the care sector and beyond.
Today, our experts for sponsor licence assistance at UK Visas will guide you through the implications of this case so you can benefit from the recent developments while sponsoring migrant workers.
Background of the Case
Hartford Care Group Ltd, a leading care home provider in the UK, operates 19 care homes nationwide. It found itself in a legal battle after the Home Office refused to grant it 70 DCoS to recruit overseas workers. On January 9, 2024, Hartford made its initial request for the sponsorship certificates, and it previously obtained approval for 93 DCoS.
Later, the Home Office demanded that Hartford Care Group provide official contracts to prove the vacancies were authentic after their initial application. The request was denied on January 24, 2024, because no minimum work hours were documented within the submitted contracts. This prompted Hartford to challenge the refusal through judicial review.
Key Findings of the Ruling and Court’s Rationale:
Unlawfulness of Guaranteed-Hours Requirement
The court ruled that the Home Office's demand for work agreements with specified working hours to demonstrate legitimate employment positions was unjustified and irrational.
It highlighted that professional contracts in the care sector operate differently from standard practices because the sector needs adaptable staff schedules that can adjust according to local authority demands and user requirements.
Recognition of Genuine Vacancies Without Guaranteed Hours
The judgment validated that job openings can be legitimate despite lacking guaranteed working hour agreements. The court acknowledged flexible staffing systems as standard operational features in the care sector and asked the Home Office to consider them while making immigration-related decisions.
Criticism of Home Office Practices
The court criticised the Home Office for imposing additional requirements not outlined in immigration rules or published policies. This approach was impermissible as it burdens care providers and fails to consider industry norms.
Quashing of Home Office Decision
The High Court quashed the Home Office’s rejection of Hartford Care Group’s application for 70 Defined Certificates of Sponsorship (DCoS) and declared it unlawful. This decision was made to encourage more transparent and reasonable application criteria for those sponsoring overseas workers in the future.
What This Means for UK Employers Hiring Overseas Workers
Now that we have a thorough understanding of the R (Hartford Care Group Ltd) v Secretary of State for the Home Department rulings, let’s take a look at what they imply for you as an employer in the UK:
Policy Implications for the Home Office:
Review of Sponsorship Criteria
The ruling compels the Home Office to reassess its approach to evaluating Defined Certificate of Sponsorship (DCoS) applications. It demands the Home Office to implement transparent and realistic criteria for those applying for sponsoring migrant workers, as the requirement for guaranteed-hours contracts was deemed irrational and inconsistent with immigration rules.
Greater Accountability
The Home Office has to adhere to published policies and avoid unpublished or arbitrary requirements. This will ensure fairer treatment for you as an employer if you belong to sectors like adult social care that rely heavily on flexible staffing arrangements.
Improved Consultation with Stakeholders
The ruling demands that policymakers like the Home Office consult with industry representatives to better understand operational realities in various sectors. This will result in more transparent policies and fewer legal challenges when sponsoring migrant workers.
Flexibility in Employment Contracts:
Recognition of Sector-Specific Practices
Due to the recognition of flexible contracts in sectors like adult social care, where staffing needs fluctuate depending on external factors such as local authority funding and service user demands, contracts can now be structured without fear of rejection based on rigid requirements.
Encouragement for Innovative Staffing Models
As a UK-based employer, the ruling encourages you to explore flexible work arrangements, such as self-rostering or team-based scheduling, which are highly effective in sectors like health and social care. This flexibility will improve worker satisfaction while ensuring that operational needs are met.
Reduced Administrative Burden
Since the court has eliminated the need to produce guaranteed-hours contracts for DCoS applications, you can now enjoy a straightforward recruitment process without unnecessary documentation and delays.
Encouraging Ethical Recruitment Practices:
Alignment with Global Standards
The ruling demands that you, as an employer, adhere to ethical recruitment practices when sponsoring migrant workers. This implies that they must be paid fairly and provided with adequate support upon arrival.
Safeguards Against Exploitation
The court clarifies that although the absence of fixed-hour contracts does not breach sponsorship requirements, you must ensure that migrant workers are not subjected to exploitative conditions or unreasonable contractual obligations. You must also be transparent and fair during the hiring process.
Focus on Genuine Vacancies
The judgment highlights the need for employers to demonstrate genuine staffing needs without imposing unattainable requirements. This will foster trust between employers, workers, and government agencies while ethically addressing labour shortages.

Frequently Asked Questions
What is a sponsored worker?
A sponsored worker is an overseas worker authorised to work in the UK under a specific visa scheme. To get this authorisation, they need a licensed employer willing to sponsor them and a Certificate of Sponsorship, which allows them to come to the UK and work legally.
Here are some of the most common visa routes for sponsored workers:
Skilled worker visas (e.g., healthcare, engineering)
Health and care visas (for eligible NHS and social care roles)
Temporary worker visas (e.g., Seasonal Worker, Creative Worker)
Who is eligible for visa sponsorship?
To be eligible for sponsorship in the UK an employer must:
Have no unspent criminal convictions for immigration offences or any other type of offence
Have a legitimate business that operates legally in the UK
Have a proper system in place for managing sponsored workers and complying with reporting obligations
For a worker to be eligible for sponsorship, they must:
Have a job offer from an employer with a valid sponsorship licence
Have a Certificate of Sponsorship
Have a job that meets the minimum salary thresholds (varies by visa type)
Meet the skill requirement as per their visa type
What is the minimum salary for sponsorship?
Generally, the minimum salary threshold for a skilled worker visa is £38,700 per year, while that for a Health and Care Visa is £25,000/year (£12.82/hour).
How will the new rule affect the current workforce in the care sector?
Here are the probable effects of the new rule on the current workforce in the UK care sector:
Care providers can continue employing overseas workers under arrangements to meet the fluctuating demand
It reduces administrative burdens and prevents unjustified rejection of sponsorship applications
It will safeguard existing workers by prioritising ethical recruitment practices that ensure fair treatment and reduce exploitation risks
What are the potential financial impacts of the new rule on care providers?
The new judgment eliminates the administrative burden of guaranteed-hours contracts, reducing potential compliance costs. However, it does not address broader financial challenges such as rising National Insurance contributions and local authority funding constraints.
Due to these external factors, care providers might still face increased operational costs, potentially leading to higher service charges for clients. The ruling ensures more flexibility in staffing, which could help manage costs by aligning workforce needs with fluctuating demand. Overall, financial stability remains a challenge despite this legal victory.
How could this decision impact the relationship between care providers and local authorities?
The Hartford ruling will likely strengthen the relationship between care providers and local authorities by fostering collaboration and mutual accountability. By validating flexible staffing models, care providers can better adapt to fluctuating demands driven by local authority contracts, ensuring continuity of care.
The decision also emphasises the need for transparent communication regarding funding and recruitment practices, encouraging local authorities to support ethical hiring processes. Furthermore, the ruling may prompt local authorities to reassess their obligations under the Care Act 2014, ensuring adequate funding for eligible residents. This improved alignment could reduce disputes and enhance trust between both parties.
