The Home Office has introduced one of the most significant changes to the UK’s illegal working regime in recent years. Following the publication of the revised Code of Practice on 30 June 2026, the new framework will take effect from 1 October 2026, fundamentally changing who businesses must carry out right to work checks on and increasing the potential exposure to civil penalties.
For many organisations, these reforms will require a complete review of existing onboarding, procurement and contractor engagement processes.
What has/will change?
Historically, the obligation to carry out right to work checks applied primarily to individuals employed under contracts of employment or service. From 1 October 2026, section 48 of the Border Security, Asylum and Immigration Act 2025 extends the illegal working regime to a much wider range of working arrangements. This means organisations can no longer assume that immigration compliance rests solely with the direct employer. Depending on the working arrangement, businesses engaging labour through contractors, subcontractors, consultants, freelancers and other non-traditional arrangements may now have right to work obligations and could face civil penalties where illegal working is identified.
