Right to Work Checks for UK Contractors: What You Need to Know

Right to Work Checks for UK Contractors

Right to work compliance is a topic that many limited-company contractors and their clients treat as an employment-only concern. In practice, the rules are shifting, and both contractors and the businesses that engage them need to understand where responsibilities currently sit and what is changing from 2026 onwards.

The Current Position: Are Checks Mandatory?

For genuinely self-employed UK contractors operating through their own limited company, right to work checks are not currently mandatory for the end client under general Home Office rules. The legal obligation to conduct a statutory check attaches to employers engaging employees or workers, not to businesses procuring services from an independent contractor.

That said, the Home Office strongly encourages end clients to satisfy themselves that contractors either conduct their own right to work checks on any staff they deploy, or that the client performs checks directly. Ignoring this guidance may not attract an automatic penalty today, but it leaves a business exposed if the position of a contractor later becomes contested.

See the GOV.UK guidance on checking a job applicant's right to work for the authoritative statement of current obligations.

When a Check Is Already Mandatory

There is one scenario in which a right to work check is mandatory right now, regardless of whether the individual is a contractor: where the contractor is sponsored on a Skilled Worker visa or another sponsored route.

If your business holds a sponsor licence and is engaging a contractor who entered the UK under a sponsored visa, you must conduct a mandatory right to work check. Failure to do so can result in a civil penalty of up to £20,000 per illegal worker, and in serious cases, criminal liability. There is no discretion here.

Brightmine's HR compliance resource sets out the current framework clearly for those wanting further detail.

What Changes From April and October 2026

The compliance landscape for UK contractors is about to change significantly.

From 8 April 2026, right to work checks are expanded by law for businesses that hold a sponsor licence. The expanded duty will cover not just directly employed workers but also contractors, subcontractors, and individuals engaged through online matching platforms.

From 1 October 2026, full implementation of mandatory checks for all workers engaged by a business is expected to apply more broadly, moving beyond sponsored workers only. It is important to note that as of the time of writing, the relevant legislation was still in draft form. Contractors and clients should monitor updates closely.

Sources covering these incoming changes include the Access UK Visa analysis on LinkedIn and the YunoJuno blog on verifying contractor right to work in the UK.

Using the Home Office Online Service

For any contractor who holds a Biometric Residence Permit (BRP) or a Frontier Worker Permit (FWP), the only acceptable method of verification is the Home Office online share code service. Physical documents, including BRP cards, are no longer accepted as valid evidence for a right to work check.

The process works as follows:

• The contractor generates a share code via the GOV.UK view and prove your immigration status service
• The engaging business or client enters the share code and the contractor's date of birth into the Home Office online checker
• The checker returns a result confirming whether the individual has the right to work and, where relevant, any time limit on that right

Using the online service and retaining the result provides a statutory excuse against a civil penalty if a check is later found to have been incorrect, provided the check was conducted in good faith.

Practical Steps for Contractors and Clients

Contractors and the clients who engage them should consider the following:

• Contractors: Understand your own right to work position. If you employ staff through your limited company, you carry the obligation for those individuals as their employer. Keep records of any checks you conduct.
• End clients: Assess whether you hold a sponsor licence. If you do, mandatory checks for contractors are coming from April 2026. Begin reviewing your onboarding processes now.
• Everyone: Do not rely on physical BRP cards or other legacy documents. Insist on the online share code process where applicable.
• Check the legislation: The October 2026 expansion was still in draft at the time of writing. Subscribe to GOV.UK immigration updates to stay current.

Why This Matters for IR35 Decisions

Right to work compliance sits separately from IR35 status, but the two are often considered together during contractor onboarding. Clients who are bringing greater scrutiny to the engagement of contractors for right to work purposes may also be reviewing their IR35 supply chains. Contractors should be prepared for more thorough due diligence from clients, particularly sponsor licence holders, from mid-2026 onwards.

This platform does not determine, verify, or warrant IR35 status; the SDS is the client's legal responsibility. Contractors should take their own advice and consider IR35 insurance.
