Right to Work Checks: The Mistake That Costs £45,000

Most employers know they need to do right to work checks. Fewer know exactly what ‘correct’ looks like. And the gap between the two can be expensive.

The Home Office can fine businesses up to £45,000 per illegal worker for a first breach and up to £60,000 for repeat offences. These aren’t theoretical risks. Enforcement activity has increased significantly, and the checks that are failing audits are often not missing entirely. They’re just done wrong.

Here’s what the law requires, where businesses most commonly go wrong, and how to build a process that protects you.

Key facts at a glance

  • Every UK employer must carry out a right to work check before a new employee starts work. This is a legal requirement.
  • Employers can be fined up to £45,000 per illegal worker for a first breach, rising to £60,000 for repeat offences.
  • Accepting a photo or scanned copy of a document does not constitute a compliant check.
  • Time-limited right to work must be tracked and rechecked before expiry or you lose your statutory excuse.

What is a right to work check?

A right to work check is a mandatory process every UK employer must carry out before a new employee starts work. It involves verifying that the individual has legal permission to work in the UK by examining original documents in person, or by using the Government’s online checking service where applicable. Completing the check correctly gives the employer a statutory excuse against a civil penalty if illegal working is later discovered.

The key word is correctly. Simply having a document on file is not enough. The check must be carried out in a specific way, and the statutory excuse only applies if the prescribed process was followed.

Documents fall into two categories. List A covers those with a permanent right to work in the UK, including British and Irish passport holders. A single compliant check at the start of employment is sufficient for these individuals. List B covers those with time-limited permission, such as visa holders, who require an initial check and a follow-up check before their permission expires.

Where businesses most commonly get it wrong

Accepting copies or photographs instead of originals

One of the most common failures we see is managers accepting a photo of a passport sent via email or WhatsApp. This does not constitute a compliant check. Original documents must be physically inspected in person, or the Government’s online share code system must be used where the individual holds a digital immigration status.

The rule is straightforward: you must see the original document and satisfy yourself that it’s genuine. Email copies, WhatsApp photos, and scanned PDFs have no legal standing regardless of whether the underlying document is authentic. Using them removes your statutory excuse entirely.

Delegating without training

Right to work checks are sometimes delegated to line managers or team leaders who have never been properly briefed on what to look for or what the process requires. A check carried out by an untrained person, even with good intentions, may not be compliant.

Training doesn’t need to be complex. Managers need to know which documents are acceptable, how to examine them properly, and what to do if something doesn’t look right. A one-hour briefing with a clear reference guide is usually sufficient. An untrained manager who accepts the wrong document type removes your statutory excuse entirely.

No system for tracking expiry dates

For employees with time-limited right to work, such as those on a visa, the initial check is just the start. You are required to carry out a follow-up check before their permission expires. Without a tracking system, these deadlines can pass unnoticed.

A spreadsheet or HR system reminder is sufficient. What matters is that someone owns it and that reminders fire early enough to act before expiry. If an employee’s right to work lapses and you’ve continued employing them without a valid recheck, you lose your statutory excuse even if the original check was done perfectly.

Poor record keeping

Even where checks are done correctly, poor documentation means you cannot prove it. Records must be retained for the duration of employment and for at least two years afterwards. Failing to produce evidence during a Home Office audit is treated the same as failing to do the check at all.

The copy should be clear, dated, and stored securely. For online checks, save or print the result from the checking service. Store records consistently so that if an inspector asks to see a specific employee’s file, you can produce it immediately.

A real example: how one business fixed its process

We worked with a busy manufacturing company in the West Midlands that had recently moved right to work checks from HR to line managers during the interview process. Within a short time, it became clear that several managers were accepting photographs of documents via email rather than physically inspecting originals.

Although the documents were believed to be genuine, the process was non-compliant. We stepped in with a practical remediation plan: manager briefings across all supervisory levels, a standardised checklist embedded into the onboarding process, an audit of all existing employee files, and a tracker to flag visa expiry dates for follow-up checks.

The business achieved full compliance within six weeks. The audit gave them peace of mind they hadn’t had before, and the new process took far less time to run than the previous ad hoc approach.

How to build a compliant process

  • Carry out checks before the employee starts, not after
  • Inspect original documents in person, or use the Home Office online service for those with a share code
  • Take a clear copy of the document and date it on the day of the check
  • Keep records securely for the duration of employment plus two years
  • Create a tracker for time-limited permissions and diarise follow-up checks before expiry
  • Train anyone involved in recruitment on what a compliant check looks like

If you use agency workers, also confirm what right to work verification your agency carries out. You may not be liable in the same way, but it’s important to understand the cover you have.

The process is not complex, but it does need to be consistent. The biggest compliance failures come not from deliberate evasion but from inconsistency: checks done well for some employees and poorly for others, record-keeping that works for permanent staff but not agency workers, training that reaches HR but not the managers actually running interviews. Building the process once, training the right people, and reviewing it annually takes a few hours. The cost of not doing it can run to tens of thousands.

Get it right before an inspection finds it

Right to work compliance is one of those areas where the cost of getting it wrong far outweighs the cost of getting it right. Non-compliance doesn’t always look like a deliberate act. Often it’s a process that drifted, or a check that was done well for one person and poorly for another.

If you’re not confident your current process is fully compliant, our retained HR support includes compliance reviews that can identify and fix gaps before they become a problem.

FAQS

  • What documents are acceptable for a right to work check?

    Acceptable documents include a UK or Irish passport, a biometric residence permit, a document from the Home Office confirming right to work, or a share code from the Government’s online checking service. The Home Office publishes a full list of acceptable documents in its employer guidance, which is updated regularly. Always check against the current version before carrying out checks.

  • Can I do a right to work check remotely?

    For individuals with a digital immigration status, you must use the Home Office online share code service, which can be completed remotely. For individuals with physical documents such as a British passport, you must inspect the original in person. Temporary COVID-era adjustments allowing video checks have now ended. There are also certified digital identity service providers approved for certain checks on British and Irish citizens.

  • How long do I need to keep right to work records?

    You must keep copies of right to work documents for the duration of the individual’s employment and for at least two years after it ends. Records should be clear, dated, and accessible in the event of a Home Office audit. For online checks, save or print the result from the checking service at the time it is carried out.

  • What happens if I employ someone without the right to work?

    If you employ someone who does not have the right to work in the UK, you may face a civil penalty of up to £45,000 per worker for a first breach and up to £60,000 for repeat breaches. You will only have a statutory excuse against the penalty if you can demonstrate that the prescribed right to work check was carried out correctly before they started. In serious cases, criminal prosecution is also possible.

  • Do right to work checks apply to self-employed contractors?

    Strictly speaking, right to work checks apply to employees and workers, not to genuinely self-employed contractors. However, if there is any uncertainty about the employment status of someone you engage, it is worth seeking HR or legal advice before they start work, both to make sure you are compliant and to protect against misclassification risk.

  • From the initial conversation with Lisa, it was clear we needed to improve our contract and guide to help the new contractors understand the business and what is expected of them whilst working with us. The whole process has been seamless and working with both Lisa and Helen has been relaxed and clear throughout, the discussions to make sure all the information needed has been thorough and I am very pleased with the final results provided by Helen at Limelite HR. if I had not spoken to Lisa initially we would have been using an outdated contract with lots of loopholes and we wouldn’t have the User Guide to help promote our business. It has been an invaluable help to me and my business.
