Key Visa Rule Changes for 2025

Major visa rule changes activate on 22 July 2025, significantly impacting UK immigration. The Home Office aims to drastically cut net migration via these 2025 reforms. Employers face dramatically higher costs for sponsoring Skilled Workers under the new regime. Issuing a CoS before this date can bypass some harsh new rules.

The Skilled Worker visa replaced the former Tier 2 (General) visa route, streamlining work migration. Minimum skill level for new applicants elevates to RQF 6 (graduate) from the previous RQF 3. This shift targets higher-skilled graduate roles, aligning with evolving UK immigration policy. Overseas recruitment for care workers will cease from July 2025.

Understanding CoS Types and Validity

Defined CoS

Required for overseas applicants applying for a Skilled Worker visa from outside the UK. These are allocated by the Home Office monthly.

Undefined CoS

CoS Validity

A Certificate of Sponsorship is valid for only 3 months from its issue date. You must apply for your visa within this critical timeframe.

Health & Care Visa

This route offers lower fees and an Immigration Health Surcharge (IHS) exemption, providing a clear pathway for eligible professionals.

Salary Thresholds and Home Office Scrutiny

The general salary threshold surges from £38,700 to £41,700 in 2025, posing new challenges for employers. Employers must adapt to significantly higher salary thresholds for sponsored roles. Rising costs characterize all UK immigration routes for 2025, increasing the financial burden. The CoS assignment fee alone is £525, with visa fees adding substantially.

Inaccurate CoS or job codes risk immediate visa application refusal. Strategic planning of CoS volumes is vital to prevent recruitment delays and ensure compliance.
