The Paperwork Hurdle: Auditing Your Right to Work Before a UK Start Date

A UK job offer can stall at the least glamorous stage of the process: the paperwork. Candidates often prepare carefully for interviews, rehearse salary discussions and line up references, yet give little thought to the documents that prove they may legally work in the United Kingdom. When a hiring team reaches the compliance stage, a missing share code, an expired passport or a name mismatch can delay a start date and, in some cases, withdraw an offer altogether.

At BPL Jobs, the pattern is familiar. The right-to-work check is not an administrative afterthought. It is a legal requirement on employers, and it sits alongside the contract, the reference and the payroll setup as part of the final gate. A sensible candidate audits the evidence before the question is asked.

What Employers Are Actually Checking

Since the move to online immigration status services, the right-to-work check has become more digital but not necessarily simpler. Employers must establish that a person has the correct permission to work, and they must retain evidence of the check. For many candidates, this means one of two routes: a manual document check for British or Irish citizens and certain others, or an online check using a share code for those with a digital immigration status.

The precise documents accepted are set out by the Home Office and are commonly described as List A and List B. List A documents generally demonstrate a permanent right to work. List B documents demonstrate a time-limited right, often subject to conditions such as maximum hours, a specific employer or a fixed end date. Employers are not permitted to accept expired documents, and they must satisfy themselves that the photograph and personal details match the candidate.

For British and Irish citizens, a current passport is usually the cleanest route. Some employers also accept a birth or adoption certificate combined with an official document showing the person’s National Insurance number. The exact combination matters, so candidates should not assume that a driving licence alone will suffice. For visa holders, the online service is central. The candidate generates a share code, the employer checks it through the Home Office service, and the result confirms the status and any conditions attached to it.

The Documents That Commonly Trip People Up

The first recurring problem is expiry. A passport that was valid at interview may be close to expiry by the proposed start date. Some candidates assume that an expired biometric residence permit remains usable because it was once the central proof of status. In practice, the shift to eVisas means that many people now rely on an online account rather than a physical card. A card that has expired or been superseded should not be presented as the primary evidence without checking the current route.

The second problem is the share code itself. Share codes are time-limited and are typically valid for a short period. A code generated for one application may not be appropriate weeks later, and a code issued for a different purpose may not produce the right result. Candidates should generate a fresh code when an employer requests one and should check that the details shown in the online service match the name and date of birth on their passport.

The third problem is inconsistency. A marriage certificate, a deed poll or a variation in spelling can create a mismatch between the name on a passport, the name on a visa and the name on a payroll system. Employers are required to satisfy themselves that the person is who they claim to be. A simple covering explanation and supporting evidence can prevent a routine check from becoming an escalated query.

The fourth problem is conditionality. A visa may permit work but restrict the number of hours, the type of role or the employer. A candidate moving from a sponsored role to a new employer may need a new sponsor licence arrangement or a fresh permission. A student visa may carry term-time limits. A dependant visa may have different conditions from the main applicant’s visa. These are not details to discover after accepting an offer.

Auditing Your Own Position Before You Apply

A practical audit begins with the documents themselves. Check the expiry date on a passport and allow enough time for renewal if it falls close to a proposed start date. Log in to the relevant Home Office account and confirm that the status shown is current, that the personal details are accurate and that the conditions are understood. If a physical card has been replaced by an eVisa, do not rely on the old card as the main evidence.

Next, prepare a short document trail. That may include a current passport, a share code generated on the day of the check, evidence of any name change and, where relevant, a certificate of application or a letter from the Home Office. Candidates with a pending application should be particularly careful. A pending application is not the same as a granted status, and the evidence an employer may accept depends on the route and the stage of the application.

It is also worth checking the timing of the check against the start date. A share code generated too early may expire. A passport renewal may take longer than expected. A sponsor transfer may require coordination between the old employer, the new employer and the Home Office. Building a buffer of several weeks is prudent where any document is due to change.

Resolving Gaps Without Panic

Where a document is missing, the first step is to identify the exact route the employer will use. A British citizen without a current passport may be able to use an alternative combination. A visa holder should use the online service rather than presenting an old card. A candidate with a pending application should ask the employer what evidence it can accept and should not assume that a certificate of application automatically confirms a right to work in all circumstances.

If the position is unclear, specialist immigration advice is appropriate. Employers are not immigration advisers, and a job board cannot resolve a status question. The aim of an audit is to surface the issue early, gather the right evidence and give the hiring team a clear route to complete its check.

The right-to-work check should not be the moment an offer unravels. Treated as part of the application, it is a manageable piece of preparation. Treated as an afterthought, it can become the document that expires before the contract does. Candidates who audit their paperwork before the final hurdle give themselves the best chance of a clean start date and a calmer first day.
