UK Points-Based Immigration System: A Technical Guide for HR Systems, Compliance Tools, and Developers

The UK Points-Based Immigration System (PBS) is the framework governing all work-related immigration since January 2021. If you build HR software, compliance tooling, or anything that touches workforce management in UK-operating businesses, the PBS is infrastructure you need to understand — because your users are navigating it daily and your data models may need to reflect it.

System Overview

The PBS replaced EU free movement and unified immigration rules so they apply equally to all non-UK nationals. Every route assigns points to criteria. Clear the threshold, you qualify. Fall short, you don't.

The dominant route for skilled professionals is the Skilled Worker visa. Most product and engineering teams building HR or people-management software will encounter this route above all others.

Threshold: 70 points

Points structure for Skilled Worker:

The mandatory 50 non-tradeable points must always be met. The remaining 20 come from salary, with limited substitution mechanisms.

Key Data Points for HR System Integrations

If you're building anything that tracks, validates, or surfaces visa compliance data, here are the core entities and their sources:

Sponsor Licence Register

The Home Office publishes a CSV of all licensed sponsors (and revoked licences). The file is updated frequently — typically multiple times per week.

• URL: https://assets.publishing.service.gov.uk/media/.../register-of-licensed-sponsors-workers.csv
• Columns include: Organisation name, town/city, county, type (employer/education), route(s) authorised
• Use case: Verifying whether an employer can legally issue a Certificate of Sponsorship; building company search UX

Certificate of Sponsorship (CoS)

A CoS is an alphanumeric reference number that a licensed sponsor assigns to an individual worker. It's unique per application and contains job title, salary, start date, and sponsor details. The worker includes it in their visa application.

HR system implication: You may need to generate or log CoS references, track assignment status, and flag expiry.

Salary Thresholds (2024 onwards)

The April 2024 changes raised thresholds significantly:

• General threshold: £38,700/year or the "going rate" for the SOC code, whichever is higher
• New entrant threshold: £30,960/year or 70% of the going rate
• Health and Care Worker: Role-specific, typically lower
• Immigration Salary List discount: 20% reduction on going rate for listed shortage occupations

Thresholds are set per Standard Occupational Classification (SOC) code. If your system matches job titles to SOC codes, this is where salary eligibility logic lives.

SOC Code Mapping

SOC 2020 codes underpin the skill level and salary threshold assessments. The Home Office's Skilled Worker appendix publishes a full table of approved occupations, their codes, minimum salary rates, and whether they appear on the Immigration Salary List.

If you're building a job eligibility checker, this table is your core reference dataset. It changes with each immigration rule update (typically announced in the Statement of Changes to the Immigration Rules).

Compliance Obligations as Data Events

Licensed sponsors have ongoing reporting duties. These map well to event-driven architectures:

• Worker starts role → Confirm start date within 10 days
• Worker's role changes significantly → Report via Sponsor Management System (SMS)
• Worker stops working → Report within 10 days
• Worker's contact details change → Update in SMS
• Absence exceeds 10 consecutive days (unauthorised) → Report

Failure to report triggers compliance visits. Sponsors can be downgraded from A-rated to B-rated, or have licences revoked entirely. If you're integrating with an SMS or building middleware around sponsor duty tracking, these are the trigger conditions.

The Sponsor Management System (SMS)

The SMS is the Home Office's portal for sponsors to manage licences, assign CoS, and file reports. It doesn't have a public API. Integration has traditionally required browser automation or manual workflows, which creates challenges for teams building automated compliance flows.

Workarounds used in practice:

• Scheduled data exports + human review workflows
• Robotic process automation against SMS
• OISC-adviser-managed portals that handle SMS interactions on behalf of sponsors

Graduate and Global Talent Routes (Lower HR Overhead)

Graduate visa: No sponsor required. Students who complete a qualifying UK degree can work for 2 years (3 for PhD graduates). Employers don't need a licence to hire Graduate visa holders, which meaningfully reduces compliance overhead. HR systems should surface visa type and expiry — not all "permitted to work" statuses are equal.

Global Talent visa: Endorsement-based. No employer sponsorship needed. Relevant primarily for hiring in R&D, deep tech, or academia. Visa holders can switch jobs freely without new sponsorship.

Building on Public Immigration Data

The register of licensed sponsors is one of the most useful public datasets in UK employment. At 125,000+ entries, it enables:

• Employer vetting flows in job platforms
• Candidate pre-screening ("is this company able to sponsor?")
• Market intelligence (e.g., which sectors have most active sponsors)
• Revocation alerting for compliance-sensitive HR functions

For tools and search access to the sponsor register, ImmigrationGPT provides a searchable interface and AI-assisted Q&A on UK immigration rules.

Summary: What the PBS Means for Your Systems

The UK Points-Based System is rules-based, threshold-driven, and deeply dependent on structured reference data (SOC codes, salary tables, sponsor registers). For developers and HR tech teams, this translates into:

• Reference datasets that need regular refreshing (salary tables, SOC appendices, sponsor register)
• Event-driven compliance workflows tied to specific employment changes
• Access control logic that distinguishes visa types and working permissions
• UI/UX that helps users navigate complex eligibility trees without becoming immigration lawyers themselves

The system isn't going away, and it's become more complex — not less — since 2021. Building well-informed tooling around it is a genuine product differentiator.
