What Is a CoS in Healthcare? Meaning, SOC Codes, Sponsorship 2026

KEY TAKEAWAYS CoS for UK Health Care Visa

CoS = Certificate of Sponsorship, a reference number (not a paper certificate) a licensed employer assigns in the SMS so an overseas nurse, doctor, or health worker can apply for a Health and Care Worker visa.
SOC codes are chosen on duties, not job titles. Registered nurses are 2231, medical practitioners 2211, care workers 6135, senior care workers 6136, recheck Appendix Skilled Occupations each time.
What makes it a "health and care" CoS is the eligibility statement: the professional registration (NMC, GMC, etc.), the salary threshold, and, for private providers, the NHS contract or CQC-regulated activity.
Costs in 2026: £525 CoS fee (employer) and £324/£628 visa fee (applicant), with no Immigration Health Surcharge and no Immigration Skills Charge, saving £5,000+ per hire vs the standard route.
Care worker closure: no new overseas CoS for SOC 6135/6136 since 22 July 2025; in-country switching runs to 22 July 2028. Nurses and doctors are unaffected.

CoS in Healthcare: Meaning, SOC Codes, and How It Works for Nurses and Doctors

CoS stands for Certificate of Sponsorship, the electronic record a licensed UK employer assigns to an overseas worker so they can apply for a visa. In healthcare, it's the step where you sponsor a nurse, doctor, or other clinical professional for a Health and Care Worker visa: a reference number, generated in the Home Office Sponsor Management System (SMS), that sets out the role, salary, and occupation code and confirms the job qualifies for the health and care route.

This guide covers what's specific to sponsoring health and care staff, the SOC codes, the eligibility statement, the costs, and the 2025 care-worker rules.

What a Health and Care CoS must include

For a nurse or doctor, the CoS records the role, salary, weekly hours, work location, and SOC code, plus the part that's unique to this route: a short statement confirming the job qualifies for the Health and Care visa. That means naming the professional registration (for example, NMC for nurses or GMC for doctors) and confirming the salary meets the threshold. If you're a private provider rather than an NHS trust, you also evidence your NHS contract or CQC-regulated activity.

Get that statement clean and decisions come faster; leave it vague and you invite queries. Two practical points catch employers out: the CoS is valid for three months from assignment, and it can be assigned no earlier than three months before the start date on the certificate.

SOC codes for healthcare roles

The SOC (Standard Occupational Classification) code tells the Home Office which job you're sponsoring, and it's chosen on the worker's day-to-day duties, not their job title, the single most common cause of healthcare CoS refusals. The codes that matter most:

Role	SOC code	Registration
Registered nurses (all specialties)	2231	NMC
Medical practitioners (doctors)	2211	GMC
Care workers / home carers	6135	Closed to new overseas recruitment (see below)
Senior care workers	6136	Closed to new overseas recruitment (see below)

Other clinical roles, midwives, pharmacists, paramedics, physiotherapists, radiographers, have their own codes and registration bodies (HCPC, GPhC, GDC, GOC). Confirm the exact code and its going rate against the Home Office Appendix Skilled Occupations each time, since thresholds are reviewed yearly against ONS earnings data.

Before you assign: sponsor licence and CQC

Only licensed sponsors can assign a CoS, so your organisation needs a valid Home Office sponsor licence first.

For care roles in England there's an extra gate:

you must be registered with the Care Quality Commission (CQC) before you can sponsor.
If you're not licensed yet, our sponsor licence guide for health and care employers covers eligibility, key personnel, and the application.
The mechanics of assigning the certificate through the SMS are the same as any route and are covered in the guides linked above, what changes for health and care is the eligibility statement and the registration check.

The care worker CoS closure, read before you sponsor

Since 22 July 2025, you cannot assign a Certificate of Sponsorship for a care worker or senior care worker (SOC 6135 and 6136) to someone applying from overseas, that recruitment route is closed now.

Workers already in the UK can still be switched or extended into these roles until 22 July 2028.
Separately, new care workers have been unable to bring dependants since 11 March 2024.
Nurses, doctors, and other clinical roles are unaffected; this applies to the care codes only.

What are Health and Care CoS costs in 2026?

Cost	Amount (2026)	Paid by
Certificate of Sponsorship fee	£525 per CoS	Employer
Visa application fee (up to 3 years)	£324 per person	Applicant (often reimbursed)
Visa application fee (over 3 years)	£628 per person	Applicant (often reimbursed)
Immigration Health Surcharge	£0 (exempt)	— (vs £1,035/year on the standard route)
Immigration Skills Charge	Exempt for health and care roles	— (vs £480–£1,320/year on the standard route)

Against the standard Skilled Worker route (£819 visa fee plus the IHS and skills charge), the health and care route saves well over £5,000 per hire across a five-year visa, mostly from the IHS exemption. Our sponsor licence and CoS cost update has the full employer-side breakdown.

Common CoS mistakes in healthcare, and how to avoid them

Wrong SOC code. Matching on job title instead of actual duties is the top cause of refusals. Match on duties, and recheck Appendix Skilled Occupations each time you assign a CoS.
Missing CQC registration. Care roles in England require it before you can sponsor, confirm your status first.
English evidence gaps. New applicants need CEFR B2 (IELTS 5.5 in each component) from 8 January 2026 for the visa. The NMC or GMC may require a higher standard for registration, so pre-verify both.
Pay-period shortfalls. Since 8 April 2026 the salary threshold must be met in every pay period, not just as an annual average, watch part-time and variable-hours contracts.
Allocation running out. Forecast hires quarterly so you don't stall mid-recruitment waiting on additional certificates.

Frequently Asked Questions: UK CoS for Nurses and Doctors

What does CoS stand for in healthcare?

CoS stands for Certificate of Sponsorship. In UK healthcare it is an electronic record a licensed employer assigns to an overseas nurse, doctor, or health worker so they can apply for a Health and Care Worker visa — a reference number generated in the Sponsor Management System, not a physical certificate.

What is the SOC code for a registered nurse in the UK?

Registered nurses fall under SOC code 2231, and the role requires NMC registration. The code is selected on the worker's actual duties rather than their job title, so confirm it against Appendix Skilled Occupations before assigning the CoS.

What does a Health and Care CoS need to include?

It records the role, salary, hours, location, and SOC code, plus a statement confirming the job qualifies for the health and care route — naming the professional registration (NMC, GMC, etc.), confirming the salary threshold, and, for private providers, evidencing the NHS contract or CQC-regulated activity. It is valid for three months from assignment.

How much is the Certificate of Sponsorship fee in 2026?

The CoS fee is £525 per certificate, paid by the employer. Separately, the applicant pays a visa fee of £324 (up to 3 years) or £628 (over 3 years), and Health and Care applicants are exempt from the Immigration Health Surcharge.

Can you still assign a CoS for a care worker in 2026?

Not for new overseas applicants. Since 22 July 2025, care workers and senior care workers (SOC 6135 and 6136) cannot be sponsored from outside the UK. Workers already in the UK can be switched or extended into these roles until 22 July 2028. Nurses and doctors are unaffected.

What English level is needed for the Health and Care visa?

New first-time applicants must meet CEFR B2 (IELTS 5.5 in each component) from 8 January 2026, up from B1. Workers already in the UK who are extending or switching remain on B1. Regulators such as the NMC and GMC may require a higher English standard for registration, so check both.
