Managing Multiple Sponsored Workers: SMS Tips for Large Companies

The SMS compliance challenge scales with headcount. Tracking CoS assignments, visa expiry dates, 10-day reporting windows, and right-to-work re-checks across dozens of sponsored workers is genuinely complex. This guide covers the structures, tools, and habits that prevent the gaps that lead to enforcement action.

New to the SMS? Start with our SMS HR Guide 2026 for the fundamentals: user roles, reporting deadlines, CoS types, and the eVisa transition. This guide picks up where that one leaves off.

Build the right team structure first

One Level 1 User managing a large sponsored workforce is a structural compliance risk. When that person is on leave, off sick, or leaves the business, reporting deadlines are missed. The recommended structure for employers with 10+ sponsored workers:

• Multiple Level 1 Users - divide the sponsored workforce into portfolios. Each Level 1 User owns a segment and is responsible for all reporting within it.
• Named backups for every Level 1 User - a second person who can step in for leave, illness, or departure without any gap in coverage.
• An immigration compliance lead - a senior HR or legal person who reviews SMS activity monthly, owns the audit relationship, and escalates issues to the Authorising Officer.
• Level 2 Users for junior HR staff who need read access but should not independently assign CoS.

When a Level 1 User leaves the business, remove their SMS access immediately and reassign their worker portfolio before their last day - not after.

Connect your HRIS to your SMS workflow

The SMS has no direct integration with third-party HR systems and no bulk-upload function. Every worker record must be updated individually. But you can build workflows around it that prevent manual tracking failures:

• Configure HRIS alerts to trigger when a sponsored worker's record is updated - the alert should name the type of change and flag that an SMS report is due within 10 working days.
• Maintain a live compliance tracker (a shared spreadsheet or your immigration platform) covering every sponsored worker's CoS reference, visa expiry date, current salary vs threshold, right-to-work last verified date, and any open reporting obligations.
• Use immigration case management software to automate visa expiry alerts at 6 months, 3 months, and 1 month out.
• Store all compliance records in a cloud-based, access-controlled system - not in local folders or email chains that disappear when someone leaves.

Handling bulk changes - salary reviews, restructures, office moves

When a salary review, restructure, or office relocation affects multiple sponsored workers at once, the reporting burden multiplies. There is no shortcut — each worker requires an individual SMS update.

• Plan salary review timelines to leave enough room before the 10-working-day reporting window closes after the effective date.
• For office moves or hybrid work policy changes, identify all affected sponsored workers in advance and schedule SMS updates as part of the change project plan.
• Keep a project log recording the date each SMS update was completed. This is your evidence if a compliance question arises later.
• For restructures that change job titles or SOC codes, take immigration advice before issuing new CoS — the role may need to be re-assessed for eligibility.

Quarterly internal audit checklist

The sponsors who avoid enforcement action treat their SMS records as if a compliance visit could happen any day. Run this check every quarter:

• All active CoS records show the correct job title, salary, SOC code, and work location.
• All reportable changes in the past quarter were submitted within the 10 or 20-working-day deadline.
• Right-to-work records have been refreshed for workers whose eVisa share codes have expired (90-day limit).
• All sponsored worker salaries still meet current thresholds (£41,700 for Skilled Worker; £48,500 for GBM Senior/Specialist Worker).
• All sponsored roles still meet RQF Level 6 or appear on the current Temporary Shortage List.
• SMS user access is current -no dormant accounts, backups confirmed for every active Level 1 User.
• All Home Office correspondence has been acknowledged and responded to within the required timeframe.

If you find a gap during an internal audit, report it proactively via the SMS and document that you did. Voluntary self-reporting is treated more favourably than failures discovered at a Home Office visit.

If you receive a compliance visit notice

Compliance visits  announced and unannounced have increased significantly since 2024. If you receive notice:

• Acknowledge immediately. For desk-based audits, documents are typically due within 5–10 working days.
• Pull records for all sponsored workers: CoS assignments, right-to-work checks, payslips, contracts, and any correspondence about changes.
• Do not alter or backdate SMS records. The Home Office can identify manipulation and it will make the outcome significantly worse.
• Consider engaging an immigration solicitor before responding, particularly if there are any known gaps in your records.
