Certificate of Sponsorship (CoS) Allocation and Assignment Process: A Complete Guide for Employers & HR Managers

What is a Certificate of Sponsorship (CoS)?

A CoS is an electronic record issued by a licensed sponsor through the Sponsor Management System (SMS) to a non-UK national, confirming their job role, salary, and visa eligibility. The CoS is a critical component for hiring non-UK nationals under routes like the Skilled Worker or Global Business Mobility (GBM) – Senior or Specialist Worker visas. There are two types of CoS:

• Defined CoS: For Skilled Worker applicants applying from outside the UK, requiring Home Office approval.
• Undefined CoS: For in-country applications (e.g., visa extensions, GBM routes) or roles not requiring pre-approval.

HR Action: Understand the distinction between defined and undefined CoS to select the correct type for each worker’s visa application.

CoS Allocation : 4-Step Process

Allocation refers to the process of obtaining CoS quotas from UKVI to assign to workers. Sponsors must request sufficient CoS to cover hiring needs.

Assess Hiring Needs:

1. Forecast the number of non-UK workers to be sponsored annually, based on recruitment plans and visa routes (e.g., Skilled Worker, GBM).
2. Consider visa durations (e.g., 3–5 years) and potential extensions.

Apply for CoS Allocation:

1. Log into the Sponsor Management System (SMS) and submit a request for defined or undefined CoS under 'Request CoS allocation.
2. For defined CoS (Skilled Worker, outside UK), apply via SMS with job details, salary, and role justification (RQF Level 6 or Temporary Shortage List).
3. For undefined CoS, request a yearly quota based on anticipated needs.
4. Processing time: 1–2 days for undefined CoS; up to 2 weeks for defined CoS.

Home Office Review:

1. UKVI assesses the sponsor’s compliance history and job role eligibility.
2. Defined CoS requires evidence of genuine vacancy and compliance with salary thresholds (e.g., £41,700 for Skilled Worker, £48,500 for GBM Senior/Specialist).

Allocation Approval:

1. Approved CoS are added to the sponsor’s SMS account for assignment.
2. Rejected requests (e.g., due to non-compliant roles) require resubmission with corrections.

CoS Allocation Costs

• CoS Fee: £525 per CoS (increased April 2025).
• Immigration Skills Charge (ISC): For Skilled Worker Visas only, £364/year (small sponsors) or £1,000/year (large sponsors). Not applicable to GBM routes.

HR Action: Plan CoS requests 3–6 months in advance to align with recruitment timelines. Budget for CoS fees and ISC for Skilled Worker roles.

CoS Assignment Process

Assignment involves issuing a CoS to a specific worker for their visa application.

Verify Worker Eligibility:

1. Confirm the worker meets visa requirements (e.g., prior employment for GBM, English proficiency for Skilled Worker).
2. Ensure the job role meets RQF Level 6 or Temporary Shortage List criteria and salary thresholds (e.g., £41,700 Skilled Worker, £48,500 GBM).

Assign CoS via SMS:

1. Log into SMS and select 'Create CoS'.
2. Enter worker details: name, nationality, passport number, job title, salary, and work location.
3. Specify visa type (e.g., Skilled Worker, GBM Senior/Specialist) and duration (up to 5 years for Skilled Worker, 5–9 years for GBM).
4. Attach supporting documents (e.g., job description, contract).

Issue CoS Reference Number:

1. Once created, the CoS generates a unique reference number for the worker’s visa application.
2. Provide the reference number to the worker within 3 months (CoS expires after this period).

Support Visa Application:

1. Guide the worker to use the CoS reference in their online UKVI application, alongside documents like passports and TB test results (if applicable).
2. Monitor application progress, as the CoS is linked to the sponsor’s SMS account.

CoS Allocation Processing Timelines

• CoS Creation: Instant for undefined CoS; 1–2 days for defined CoS approval.
• Visa Application: 3 weeks (outside UK) or 8 weeks (inside UK) standard; 5 days (priority, £500–£800) or next day (super priority, £800–£1,000).

Assign CoS promptly after allocation and verify worker details to prevent errors. Use priority services for urgent hires, refer expert CoS management guide for budgeting extra costs.

CoS Compliance Requirements in 2026

Compliance with CoS processes is critical to avoid penalties, especially with stricter 2025 audits (1,948 licence revocations from July 2024 to June 2025).

Integrate CoS tracking into HR systems to automate reporting and ensure audit-ready records.

CoS Penalties for Non-Compliance

Non-compliance with CoS processes risks severe consequences:

• Licence Downgrade: B-rating with a £1,476 action plan, halting new CoS issuance.
• Licence Suspension: Temporary halt of sponsorship, risking visa curtailments.
• Licence Revocation: Permanent loss, with a 12-month reapplication ban and £525/CoS losses.
• Civil Penalties: Up to £20,000 per illegal worker for failed right-to-work checks.
• Criminal Penalties: Up to 7 years’ imprisonment for knowingly employing illegal workers.

HR Action: Quantify penalty risks (£20,000–£100,000 for multiple violations) in process audits to justify compliance investments.

CoS Best Practices for HR Information Systems

Develop a centralized CoS workflow in HR systems, integrating forecasting, allocation, and compliance tracking.
