Secure Your Overseas Hire Without Sponsor Risk or Visa Refusal
Structured support for allocation increases, Certificates of Sponsorship (CoS) and work visa applications, aligned to current Home Office scrutiny standards.
Structured support for allocation increases, Certificates of Sponsorship and work visa applications, aligned to current Home Office scrutiny standards.
Holding a sponsor licence is only the starting point.
The operational risk now lies in how Certificates of Sponsorship are assessed, drafted and aligned with visa applications. Allocation increases are examined closely. Defined CoS requests are queried. Salary thresholds and transitional provisions require careful analysis.
A single misalignment can result in:
-
Visa refusal
-
Delayed onboarding
-
Loss of candidate confidence
-
Increased compliance scrutiny
We support UK employers in executing sponsorship correctly, from allocation strategy to visa submission, through structured, defensible submissions designed to withstand Home Office examination.

How the UK Sponsorship System Works
Employing an overseas worker under the UK sponsorship framework involves three stages:
- 1. Obtain a Sponsor Licence
Your business must hold a valid sponsor licence issued by the Home Office.
If you do not yet hold one, see our guide to applying for a sponsor licence. - 2. Assign a Certificate of Sponsorship (CoS)
Before a worker can apply for a visa, you must assign a valid Certificate of Sponsorship (CoS) via the Sponsor Management System (SMS).
This requires sufficient allocation and correct eligibility assessment. - 3. The Worker Applies for a Visa
The individual submits their visa application supported by the assigned CoS.
Approval depends on accurate alignment between the role, salary, skill level and immigration rules in force at the time of application.
Each stage must align. Errors or inconsistencies can lead to refusal, delay or increased compliance scrutiny.
Sponsorship Is Now a Risk Management Exercise
Many employers assume that once a sponsor licence is granted, recruitment becomes procedural.
In practice, the Home Office increasingly scrutinises:
- Undefined CoS allocation increase requests
- Defined CoS justifications
- Genuine vacancy assessments
- Salary threshold compliance (including transitional arrangements)
- Role and SOC alignment
- Reporting history
Allocation is frequently granted only where recruitment needs are clearly evidenced and commercially credible.
This is no longer a form-filling exercise. It is operational risk management.
How We Support Sponsorship Execution
Our work in this area is typically delivered on a matter-by-matter basis, depending on the stage of recruitment and the complexity involved.
Undefined CoS Allocation Strategy & In-Year Increases
Where annual allocation is insufficient, recruitment cannot proceed.
We support employers with:
- Allocation forecasting and workforce planning alignment
- Drafting and restructuring allocation increase submissions
- Commercial narrative development
- Evidence collation and justification
- Responding to Home Office requests for further information
- Priority submission monitoring where timing is commercially sensitive
Objective: Secure additional allocation through structured, commercially credible submissions.
CoS & Eligibility Assessment
Before a Defined CoS is submitted or an Undefined CoS is assigned, eligibility must align precisely with current Immigration Rules.
We support with:
- SOC code mapping
- Salary threshold and transitional provision analysis
- Genuine vacancy assessment
- Pre-submission risk review
- Drafting and SMS alignment
Objective: Reduce refusal risk before the visa application is lodged.
Received a Request for Further Information?
Allocation increase requests and Defined CoS submissions are increasingly met with detailed requests for further information.
These are not administrative queries. They are often targeted examinations of:
• Genuine vacancy credibility
• Salary justification
• Transitional arrangements complexity
• Role necessity
• Project timelines
• Workforce planning
• Previous allocation usage
An incomplete or poorly structured response can result in refusal, even where the underlying role is legitimate.
How We Support Requests for Further Information Responses
Even where we did not prepare the original submission, we can step in to:
- Analyse the Home Office query in context
- Identify underlying risk issues
- Restructure the commercial narrative
- Align supporting evidence to the specific concerns raised
- Draft a comprehensive response within required timeframes
Objective: Convert scrutiny into approval through structured, evidence-led responses.
Where deadlines are imminent, urgent review engagements may be prioritised subject to availability.
Priority Processing for Allocation Increase Requests
Undefined CoS allocation increases may take up to 18 weeks under standard processing.
Priority processing slots are:
- Strictly limited in number
- Released within restricted daily windows
- Frequently oversubscribed within minutes
Many sponsors struggle to secure access.
We provide a standalone monitoring service to assist eligible sponsors in obtaining a priority submission slot. Through structured monitoring of release windows and managed submission timing, most sponsors secure access within 2–5 working days.
This service relates solely to securing access to the priority mechanism. It does not require formal appointment as your legal representative or access to your Sponsor Management System.
Priority accelerates decision timelines. It does not replace the need for a robust, evidence-based submission.
Our Submission Integrity Commitment
Where we advise that a Certificate of Sponsorship or allocation increase request is ready for submission, and a refusal arises directly from drafting or narrative deficiencies within our control, we will provide corrective support without additional professional fees.
We cannot control Home Office decision-making.
We can stand behind the integrity of our work.
Work Visa Applications & Certificate of Sponsorship Assignment (Employer & Individual Support)
Once eligibility has been confirmed, the process moves to formal execution: assigning the Certificate of Sponsorship and preparing the visa application.
We support employers with:
- Drafting and assigning Certificates of Sponsorship via the Sponsor Management System
- Ensuring SOC code, salary and role details are correctly reflected
- Aligning CoS content with the Immigration Rules in force at the time of assignment
- Advising on start dates, contract alignment and reporting considerations
We support the sponsored individual with:
- Preparation and submission of the visa application
- Document guidance and eligibility confirmation
- Review of personal circumstances affecting eligibility
- Coordination of application timelines
- Ongoing communication until decision
Every visa application must align precisely with the assigned CoS. Inconsistency between the two is a common cause of refusal.
We manage both sides of the process to ensure technical consistency and structured execution from assignment through to decision.
Immigration applications are often high-pressure events for HR teams and employees alike. We provide clear oversight, defined responsibilities and controlled progression at each stage.
Your Investment
Professional fees depend on the scope and complexity of the matter.
Typical fee ranges:
- Undefined CoS Allocation Increase Request
£1,000 + VAT - Response to Additional Information (Allocation or Defined CoS)
£1,000 + VAT - Skilled Worker Visa – Full Support (CoS + Visa Application)
£2,200 - Skilled Worker Visa – Visa Application Only (CoS already assigned)
£1,500 - Skilled Worker Visa – CoS Drafting and Assigning Only
£1,100 - Priority Slot Service (Undefined CoS Annual or Allocation Increases Only)
£495 + VAT
Home Office application fees are payable separately.
Factors That May Affect Investment
Professional fees are influenced by:
• Whether support is required for CoS drafting, visa applications or both
• The complexity of eligibility and transitional salary assessment
• Whether allocation increases or additional information responses are required
• The urgency of the matter
• The volume of ongoing sponsorship activity
Employers with recurring sponsorship needs typically benefit from structured pricing arrangements, with reduced per-matter fees reflecting volume and ongoing engagement.
The commercial cost of refusal or delay often exceeds the professional fee required to structure the submission correctly at the outset.
Seek a Structured Review Before Submission
Once submitted, allocation increase requests, Defined CoS submissions and visa applications are difficult to amend.
Where recruitment timelines are commercially sensitive, structured review prior to submission can materially reduce risk.
