Applying for a Defined Certificate of Sponsorship

Applying for a Defined Certificate of Sponsorship (DCoS)

Sep 21, 2022

DisclaimerThe information in this blog is accurate as of its publication date. Any updates after that date are not reflected here.

What is a Defined Certificate of Sponsorship?

A Certificate of Sponsorship (CoS) is an electronic document with a unique reference number, that is issued by the sponsor, to a visa applicant.

Defined Certificates of Sponsorship, are used specifically for Skilled Workers applying from outside the UK and you must hold an A-rated licence to sponsor someone under this route.

Since December 2020, there have been two types of CoS – defined and undefined. Here we are talking about Defined Certificates of Sponsorship, which were formerly known as Restricted Certificates. 

How do we apply for a Defined Certificate of Sponsorship?

Before you can sponsor a migrant worker, you must first assign the Certificate of Sponsorship using the Sponsorship Management System (SMS). 

Defined Certificates of Sponsorship are used to sponsor Skilled Workers and your Sponsor Licence and you must hold an A-rated Worker Sponsor Licence to assign a Defined Certificate of Sponsorship. 

Assigning a Defined CoS is a two-step process. First you must request a Defined Certificate, then, once granted by the Home Office, the Certificate can be assigned to a candidate.

You will first need access to the Sponsor Management System (SMS). Then, your company’s Level 1, will need to complete a form on the system. They will need to provide the following information:

  • number of DCoS required
  • job title, standard occupation classification code (SOC) and a brief job summary
  • salary
  • whether the post meets the shortage occupation criteria
  • whether the worker has a PhD and if so, it should state why the qualification is relevant to the job and whether the PhD is in a Science, Technology, Engineering or Mathematics (STEM) subject) and if so, how
  • work start and end date

Once the required information is entered onto SMS, the information will be considered by the Home Office. A decision on a Defined CoS request is usually given within one working day. If further information is required from the sponsor, it could take 10 – 15 days (or more) to process.

There is no cost to apply for Defined Certificates of Sponsorship, and no priority service for Defined Certificate of Sponsorship applications.

Once the Defined CoS has been granted, the sponsor must then “assign” the CoS to the worker. The Defined CoS will be valid to assign for 3 months, from the day it is granted.

The worker then uses their assigned CoS (reference number) to complete their Skilled Worker visa application. 

They will need to make their visa application within three months of being assigned the CoS. 

Please note, once assigned, CoS are not transferable to other candidates.

When requesting and assigning a CoS, any errors on the Defined CoS form could result in a rejection of the Defined CoS request or later, a refusal of the Skilled Worker visa.

How much does the Defined Certificate of Sponsorship cost?

The cost to assign a CoS to a Skilled Worker is £199. This does not include the Immigration Skills Charge which is currently £364 (per year the CoS is assigned) for a small sponsor and £1000 per year for a large sponsor.

Conclusion 

Defined Certificates of Sponsorship are an important part of the Skilled Worker’s visa application. Without a validly assigned Defined CoS, the candidate cannot make a successful entry clearance application as a Skilled Worker. It is important to understand the requirements for the Certificates fully, since any mistakes can have a significant effect on a worker’s visa application; even to the extent of it being denied.

I was very fortunate to find AY&J Solicitors to assist me with my visa situation. My case was particularly complex. My previous visa was close to expiring, and my partner and I had scheduled our marriage for nearly three months after its expiry. At that time, I genuinely believed I had no choice but to leave the UK.However, from the very first call with AY&J, I felt reassured that I was in safe hands. They assigned Imad to my case, and he provided clear, professional advice. He explained that I could apply to extend my stay within the UK and submit a new application after our marriage, which was a huge relief for us.Throughout the entire application process, Imad carefully guided me, helping to organise all the required documents and ensuring everything was prepared with great attention to detail.I am truly grateful for their support and professionalism. Choosing AY&J Solicitors was definitely the right decision.

Ikra was very helpful and professional throughout my late application for the EU Settlement Scheme. She explained the process clearly, handled everything with great attention to detail and made what could have been a stressful situation feel straightforward and manageable. Thanks to her expertise, I successfully obtained EU settled status. I would highly recommend her 😁
