Hiring someone in the UK often starts with optimism. A good CV, a solid interview, a sense that this person might actually make Mondays easier. Then the paperwork lands. Right to work checks. Dates. Copies. Deadlines that feel oddly personal. I once watched an office manager in Soho freeze mid-coffee when she realised a follow-up check had slipped by two weeks. That pause said everything.
Right to work checks sit quietly behind most UK hiring decisions, yet the consequences for getting them wrong arrive loud and expensive.
Why these checks exist (and why they keep changing)
UK employers must confirm that every employee has permission to work before employment begins. This applies across contracts of employment, service, or apprenticeship, written or spoken, formal or loose. The Immigration Act 2016 tightened expectations and widened liability. The idea is simple enough: prevent illegal working. The practice feels less tidy.
Where work permission has an expiry date, employers must repeat checks before that date passes. Once permission ends, the individual is treated as an illegal worker by the Home Office, even if the expiry happened quietly on a Tuesday afternoon while everyone was focused on quarterly targets.
In July 2024, the Home Office adjusted guidance around EU pre-settled status. Employers no longer need follow-up checks for staff holding that status, since extensions now happen automatically. Some HR teams missed that update. Others overcorrected and stopped tracking dates altogether, which brings a different headache.
Rules move. Emails get buried. Anxiety spikes.
When checks are not required (mostly)
There are limited situations where a statutory excuse does not apply:
- People working entirely outside the UK
- Staff continuously employed since before 27 January 1997, unless their role changes
- EEA or Swiss citizens who arrived before 1 July 2021
- Under-16s on work experience
Yet there is a catch that catches people. Sponsor licence holders still need records for sponsored workers, even where a statutory excuse is not required. Compliance duties do not take days off.
3 ways to run a right to work check
Employers can choose between online checks, manual document checks, or certified identity service providers. Each route feels different in practice, even if the goal is the same.
Online Home Office checks
If a candidate provides a share code and date of birth, employers can view their status through the Home Office service. The result shows permitted work types and, where relevant, expiry dates. The photo displayed must match the person in front of you. This sounds simple until lighting, hairstyles, or ageing get involved. Keep the result, digital or printed, for the full employment period plus two more years.
British and Irish citizens cannot generate share codes. When that fact surprises a hiring manager, confusion follows quickly. Online checks also fail when migrants cannot access their code in time. In those cases, another route is needed.
Manual document checks
Manual checks still matter. They require patience and a steady hand.
You inspect original documents from the accepted lists. You confirm photos and dates of birth match. You check name variations and supporting evidence. For limited leave holders, you confirm expiry dates, work types, hours, and student term times where relevant. Then copies are made, dated, and stored securely.
This process feels old-fashioned, maybe reassuring. Paper in hand. A slight smell of ink. Yet mistakes here are common. Expired documents slip through. Restrictions are misread. Storage rules get ignored until a data breach scare jolts everyone awake.
Identity service providers and digital checks
Certified IDSPs can verify British or Irish passports using digital tools. Employers still carry responsibility, which surprises some first-time users. You must keep the IDSP report and the documents checked, again for the employment period plus two years. Outsourcing does not equal offloading liability.
When things go wrong, and they often do
Right to work checks rarely fail in dramatic ways. They fail in small, human moments.
An employee cannot find their share code. A visa extension is pending longer than expected. Someone arrived in the UK decades ago and has never held formal proof. I once sat in a meeting where silence stretched after someone asked, “What happens if we just wait?”
Waiting is risky.
If a person has a pending application, appeal, or review, employers should contact the Home Office Employer Checking Service. The same applies where a Certificate of Application or Application Registration Card instructs the employer to check status directly. Employment can begin only after receiving a Positive Verification Notice. That notice must be kept. Lose it, and the protection disappears.
Compliance pressures that sneak up on employers
Common pressure points show up again and again:
- Missed follow-up checks when diary reminders fail
- Unfamiliar visa categories, especially for asylum seekers or refugees
- Data handling that drifts away from UK GDPR expectations
- Recruitment decisions influenced by assumptions about nationality or accent
Discrimination often hides behind speed. Rushing hires creates uneven checks. That exposes employers to claims and penalties. Slowing down feels frustrating. It also saves money.
Some businesses now run internal audits every quarter. Others rely on external advisers after a scare. Both approaches cost less than a civil penalty.
Penalties that change behaviour fast
Hiring illegal workers can lead to fines up to £60,000 per individual. In serious cases, criminal charges follow, with prison sentences and unlimited fines. Courts can order business closures. Directors may be disqualified. Sponsor licences can be downgraded or revoked. Profits linked to illegal working may be seized.
Certain sectors face extra scrutiny. Alcohol sales. Late-night refreshment. Private hire and taxi services. Licensing reviews in these areas can end operations overnight. I have seen businesses try to explain gaps in records while a council officer flicked through folders without expression. It is an uncomfortable scene.
Who can work lawfully in the UK
Lawful workers include:
- British citizens, by birth or naturalisation
- Irish citizens under the Common Travel Area
- Individuals with indefinite leave to remain
- EU or EEA nationals and eligible family members with settled or pre-settled status
- Holders of UK work visas and their permitted family members
- Family visa holders
- Students with defined work rights
Each category carries its own limits. Assuming permission without checking leads straight to trouble.
A practical rhythm that helps
Many employers now tie right to work checks into onboarding software. Others prefer manual logs with calendar alerts. Neither option feels perfect. What matters is consistency. Same checks. Same timing. Same storage method.
I keep hearing HR managers describe a strange emotional cycle: confidence, doubt, relief, then doubt again. That seems fitting. Immigration rules shift. Guidance updates arrive mid-year. Systems need adjusting while business continues.
Staying compliant does not require perfection. It requires attention, records, and a willingness to pause hiring when something feels off. That pause can feel painful. It also protects the business.
London’s hiring market moves fast. The law does not slow down to match it. Keeping up means accepting a bit of friction, a few awkward conversations, and the habit of checking twice even when everything seems fine.
Sometimes especially then.
