Streamlining CoS Allocation: The Real Cost of Sponsoring Employees

When hiring international talent, obtaining and assigning Certificates of Sponsorship (CoS) is a core step—and a significant financial consideration. Understanding the full picture of costs associated with sponsorship enables HR teams to plan strategically, ensure compliance, and align talent acquisition budgets with long-term workforce ROI.

Understanding the CoS Framework

A Certificate of Sponsorship is an electronic record that allows a UK employer to sponsor a non-UK national under work visa categories such as the Skilled Worker or Global Business Mobility routes. Employers must hold a valid sponsor licence to issue CoS, and each certificate carries an assignment charge.

Key Sponsorship Costs Employers Should Plan For

1. Sponsor Licence Fees

Before issuing any CoS, a business must obtain a sponsor licence. The fee varies by company size:

• Small or charitable sponsors: £536
  
• Medium or large sponsors: £1,476
  

The licence is valid for four years, after which renewal fees apply.

2. Certificate of Sponsorship (CoS) Assignment Fees

Each time a CoS is assigned, the employer must pay a standard £239 per certificate. This charge applies to both defined and undefined CoS allocations.

3. Immigration Skills Charge (ISC)

In addition to the CoS fee, employers are normally required to pay an Immigration Skills Charge:

• Small or charitable sponsors: £364 per sponsored employee for the first 12 months, plus £182 for each additional 6 months.
  
• Medium or large sponsors: £1,000 per employee for the first 12 months, plus £500 for each additional 6 months.
  

This fee applies to most Skilled Worker and Senior or Specialist Worker routes.

4. Compliance and Administrative Costs

Ongoing sponsor duties also come with indirect costs, including:

• Time spent maintaining the sponsor management system (SMS) and updating records.
  
• HR hours dedicated to right-to-work checks, visa tracking, and renewals.
  
• Potential consultancy or legal fees for professional immigration support.
  

5. Licence Renewal Costs

Every four years, licence renewal requires a fresh submission and payment of the licence fee. Organisations often budget extra for audit preparation, internal compliance reviews, and legal oversight at renewal time.

Budgeting for Sponsorship

Effective cost forecasting means incorporating both visible and hidden expenses. HR departments should map expected recruitment volumes, visa types, and likely durations of sponsorship. It’s also essential to plan for contingencies, such as CoS requests being delayed or compliance audits requiring corrective action.

Using digital tools or managed immigration services can improve budget predictability and reduce administrative overheads by automating parts of the process, such as CoS tracking and compliance reporting.

Calculating ROI on Sponsorship

While the upfront costs of sponsorship can seem high, the ROI often comes from securing the right talent in competitive markets. ROI can be evaluated by comparing the cost of sponsorship with the value of filling critical skill gaps and the potential revenue impact of talent shortages.

Employers who model long-term workforce value—factoring in retention rates, productivity gains, and reduced turnover—typically find sponsorship to be a sustainable investment strategy rather than a compliance cost.

Optimizing CoS Allocation for Efficiency

To streamline the process, HR leaders should:

• Track CoS usage across departments to forecast needs accurately.
  
• Conduct regular internal compliance audits to avoid penalties.
  
• Leverage technology to automate reporting and deadline alerts.
  
• Engage professional immigration support to manage licence renewals and audits efficiently.
