Frontier Worker Permit UK

The Frontier Worker permit is a post-Brexit immigration route designed for EU, EEA, and Swiss citizens who work in the UK but live in another country. It was introduced to preserve certain rights of cross-border workers who, before the end of the Brexit transition period on 31 December 2020, regularly travelled to the UK for employment or self-employment without living here permanently.

The scheme enables eligible workers to continue entering the UK for work without needing a visa under the points-based immigration system. It applies to both employees and the self-employed, offering legal certainty for those whose livelihoods depend on cross-border work between the UK and the EU.

The permit is granted under the UK Immigration Rules (Appendix Frontier Worker), which set out detailed criteria for eligibility, application, and conditions of stay. Holders of the permit are not subject to sponsorship requirements and can work in almost any sector, provided their work meets the definition of “genuine and effective” economic activity under UK law and is not classed as “marginal and ancillary” activity, which is excluded.

What this article is about
This article provides a detailed, UK law–aligned guide to the Frontier Worker permit, aimed at both individual workers and UK employers. It explains the eligibility requirements, the application process, the rights and obligations attached to the permit, and important strategic considerations for maintaining status. It also examines the permit’s interaction with other UK immigration routes, right to work compliance issues for employers, and potential changes that may impact cross-border workers in the future.

Section A: Eligibility Requirements

To qualify for a UK Frontier Worker permit, an applicant must meet strict criteria set out in Appendix Frontier Worker of the UK Immigration Rules. The route is only open to certain EU, EEA, and Swiss nationals and is intended to protect the rights of those who already had a regular work connection with the UK before the end of the Brexit transition period.

The Home Office applies a combination of nationality, work activity, and residence requirements to determine eligibility. Importantly, this route is not open to new cross-border workers who did not establish this pattern of working before 1 January 2021.

1: Definition of a Frontier Worker under UK law

A “frontier worker” is defined as a person who:

• Is an EU, EEA, or Swiss citizen
• Is not primarily resident in the UK (meaning they spend fewer than 180 days in the UK in any rolling 12-month period, unless retained status applies)
• Is employed or self-employed in the UK
• Was working in the UK before 31 December 2020 and has continued to do so since

This definition is rooted in the Withdrawal Agreement and implemented in UK domestic legislation to preserve certain free movement rights for those already engaged in cross-border work.

2: Qualifying work requirements (employed and self-employed)

The work carried out in the UK must be “genuine and effective,” meaning it must be real, substantive work that is more than marginal or ancillary. For employees, this will generally involve a formal employment contract, regular shifts or hours, and work that contributes directly to the UK labour market. For self-employed individuals, the work should demonstrate commercial activity, regular engagement with clients or customers, and financial transactions consistent with operating a business.

Activities that are purely incidental or preparatory—such as occasional meetings, short visits for training, or speculative business trips—are unlikely to qualify. The Home Office may request supporting evidence such as contracts, invoices, pay slips, tax returns, or client correspondence to verify that the work meets this threshold.

3: Residence requirements – living outside the UK but working in the UK

Applicants must demonstrate that they are “not primarily resident” in the UK. This means they must spend less than 180 days in the UK in any rolling 12-month period, unless they have retained status for specific reasons. The remainder of their time should be spent in another country, typically their country of nationality.

Evidence of residence outside the UK may include tenancy agreements, mortgage statements, utility bills, council tax records, or official correspondence from government bodies. This requirement distinguishes Frontier Workers from UK-based visa holders under the points-based immigration system.

4: Exceptions and retained status (illness, unemployment, training)

A Frontier Worker can retain their status, even without currently working in the UK, if they meet one of the “retained status” provisions in the Immigration Rules. This includes situations where the worker:

• Is temporarily unable to work due to illness or accident
• Is involuntarily unemployed and seeking work in the UK (retention lasts 6 months if employed for less than 12 months before unemployment, or can be indefinite if employed for a year or more)
• Has undertaken vocational training related to their previous UK work
• Is on maternity or paternity leave from UK employment

These provisions ensure continuity of status during temporary interruptions in work, provided the applicant can prove the circumstances and their intention to return to qualifying work.

5: Brexit transitional provisions

Only those who began working in the UK before 1 January 2021 can apply for a Frontier Worker permit. New cross-border workers cannot enter the UK under this scheme and must instead apply under the appropriate visa route within the points-based immigration system, such as the Skilled Worker visa.

The scheme has no set end date, but it remains subject to potential policy changes, meaning applicants should keep up to date with Home Office guidance and renewal requirements.

Section Summary
The Frontier Worker permit is a tightly defined route that safeguards the rights of certain EU, EEA, and Swiss nationals who had an established work pattern in the UK before Brexit. Meeting the definition of a frontier worker involves proving genuine and effective work, residence outside the UK, and continuity of activity since before 2021, with certain exceptions for illness, unemployment, or training. Understanding these criteria is critical for both applicants and employers to ensure compliance and avoid refusals.

Section B: Application Process

The Frontier Worker permit application process is handled entirely online through the official GOV.UK portal. The Home Office has designed this route to be free of charge and relatively straightforward, but applicants must still prepare accurate documentation and meet the requirements set out in Appendix Frontier Worker. Any errors or omissions can lead to delays or refusals, so careful preparation is key.

1: Where and how to apply (online application process)

Applications are submitted via the GOV.UK Frontier Worker permit service. Applicants must have a valid passport or national identity card from an EU, EEA, or Swiss country and access to a compatible smartphone or device to use the UK Immigration: ID Check app. The application can be made from inside or outside the UK, provided the applicant meets the eligibility criteria.

After creating an online account, the applicant will be guided through a series of questions covering personal details, work history, and residence patterns. The application requires uploading digital copies of supporting documents and, in some cases, booking a biometric appointment if the app cannot verify the applicant’s identity.

2: Required documents (proof of nationality, work, and residence)

Evidence requirements include:

• Proof of nationality: valid EU, EEA, or Swiss passport or national ID card
• Proof of qualifying work in the UK: contracts, payslips, invoices, tax returns, letters from employers or clients
• Proof of residence outside the UK: tenancy or mortgage documents, utility bills, official correspondence, or tax records

If applying with retained status, applicants must also provide documentation supporting the relevant circumstances (e.g., medical evidence for illness, redundancy letters for unemployment, training course enrolment).

The Home Office may request further information if the initial evidence is insufficient. Documents not in English or Welsh must be accompanied by a certified translation.

3: Application fees and biometric enrolment

No application fee is currently charged for a Frontier Worker permit, but this could change in future. Applicants may still incur costs for obtaining necessary documents or translations.

If the applicant cannot use the UK Immigration: ID Check app, they will be required to attend a UK Visa and Citizenship Application Services (UKVCAS) centre to provide fingerprints and a photograph. The appointment itself is free, but premium appointment slots may carry a fee.

4: Timelines and decision process

Most applications are processed within a few weeks, but timescales can vary depending on case complexity and the need for further evidence. There is no formal priority service for Frontier Worker permit applications.

Applicants will receive confirmation by email, and the permit will be issued in the form of either:

• A digital status accessible online
• A physical Frontier Worker permit card (in certain cases, particularly for those without a compatible device)

Employers can verify a permit holder’s right to work using the Home Office’s online right to work check service, which is the standard method for most holders.

5: Common application pitfalls

Refusals can occur if:

• The applicant does not provide sufficient evidence of “genuine and effective” work
• Residence outside the UK cannot be adequately proven
• The work pattern does not show regular activity since before 1 January 2021
• Evidence provided is inconsistent, incomplete, or not in the required format

Applicants should ensure that their work and residence evidence covers the relevant time periods and is consistent across all documents. Employers may also be asked to verify the work relationship, so it is advisable to inform them of the application in advance.

Section Summary
The Frontier Worker permit application is currently free, but it requires clear, consistent evidence of eligibility and compliance with the Immigration Rules. A well-prepared application covering nationality, qualifying work, and residence outside the UK is essential. Applicants should keep copies of all documents, use certified translations when required, and be prepared for the possibility of further evidence requests from the Home Office.

Section C: Rights and Conditions

The UK Frontier Worker permit provides a defined set of rights and conditions that enable eligible EU, EEA, and Swiss citizens to continue working in the UK without needing sponsorship or a visa under the points-based immigration system. While it is a flexible route, the permit comes with clear conditions that both workers and employers must understand to avoid breaches and potential loss of status.

1: Right to work in the UK (restrictions and permitted activities)

Holders of a valid Frontier Worker permit can work in the UK without sponsorship in almost any sector or role, including as an employee or self-employed person. There are no limits on the number of employers a permit holder can work for, and work can be full-time, part-time, or seasonal, provided it meets the “genuine and effective” test.

However, work must remain consistent with the nature and pattern of activity that qualified the worker for the permit. If the worker’s circumstances change significantly—such as moving their primary residence to the UK or ceasing to meet the work requirements—they will no longer be eligible for the permit and will need to switch to a different immigration route.

Time spent in the UK under this permit does not count towards the qualifying residence period for Indefinite Leave to Remain (ILR), unless combined with time in another immigration category that is a route to settlement.

2: Access to public services and benefits

The Frontier Worker permit does not grant unrestricted access to public funds. Permit holders may access certain services—such as the NHS when they are working in the UK—but are generally not entitled to claim most UK state benefits or housing assistance. Eligibility for benefits will depend on whether the individual meets the “right to reside” and “habitual residence” tests under UK social security law.

Since Brexit, social security coordination with EU countries has changed, so cross-border workers should also check their entitlement to benefits, pensions, and healthcare in both the UK and their home country.

3: Travel rights between the UK and EU countries

Permit holders can enter and leave the UK freely for work purposes during the validity of their permit. The route is specifically for cross-border workers who live outside the UK, so maintaining regular travel between the UK and the home country is expected.

The permit does not give rights of residence in the UK outside short stays necessary for work, and prolonged stays could jeopardise eligibility if they breach the “not primarily resident” requirement.

4: Permit duration and renewal process

A Frontier Worker permit is typically granted for five years if the applicant is currently working, or for two years if applying with retained status. It can be renewed indefinitely, provided the applicant continues to meet the eligibility criteria and the scheme remains open.

Renewal applications follow the same process as the initial application and must be submitted before the current permit expires. There is no requirement for continuous work in the UK for the full duration, but the pattern of activity must still satisfy the Immigration Rules at the time of renewal.

5: Grounds for refusal, cancellation, or curtailment

The Home Office may refuse, cancel, or shorten a Frontier Worker permit if the holder:

• No longer meets the eligibility requirements
• Has provided false or misleading information in their application
• Has been convicted of certain criminal offences or poses a security risk
• Has breached UK immigration laws

A decision to refuse or cancel a permit can be challenged through an administrative review or appeal, depending on the circumstances and rights available under the Withdrawal Agreement.

Section Summary
The Frontier Worker permit gives non-resident EU, EEA, and Swiss citizens broad rights to work in the UK without sponsorship, but it is not a settlement route and does not grant unrestricted access to public funds. Holders must maintain their cross-border work and residence patterns to keep their status, and employers must ensure ongoing right to work compliance. Understanding the conditions attached to the permit helps avoid breaches that could result in cancellation or refusal at renewal.

Section D: Strategic and Legal Considerations

The Frontier Worker permit remains a valuable route for certain EU, EEA, and Swiss nationals, but it requires careful management to maintain eligibility and ensure compliance with UK immigration law. Both workers and employers benefit from understanding how this permit interacts with the broader post-Brexit immigration system, as well as the potential risks and opportunities it presents.

1: Frontier Worker permit vs Skilled Worker visa

Unlike the Skilled Worker visa, the Frontier Worker permit does not require sponsorship by a licensed employer and has no minimum salary threshold. This makes it a more flexible and cost-effective option for eligible individuals. However, the permit is not a route to settlement, whereas the Skilled Worker visa can lead to Indefinite Leave to Remain (ILR) after five years of continuous lawful residence in the UK.

For some workers, the permit may serve as a short- to medium-term solution, with a planned transition to a settlement-qualifying route in the future if they wish to live permanently in the UK. The timing of such a transition should be planned carefully to ensure there are no gaps in lawful immigration status.

2: Impact on employers and right to work checks

Employers must carry out right to work checks on Frontier Worker permit holders in the same way as for other non-British workers. In most cases, verification will be via the Home Office online right to work check service, as physical permits are less common.

It is important for HR teams to note that the permit is time-limited, so follow-up checks must be diarised and carried out before the permit’s expiry date. Failure to do so could result in a civil penalty of up to £60,000 per illegal worker (as per 2024 penalty increases) for employing someone without valid permission to work.

3: Interaction with other immigration routes

Frontier Worker permit holders who move their main residence to the UK will no longer be eligible for the permit. In such cases, they would need to switch into another immigration route, such as the Skilled Worker visa, Global Talent visa, or other relevant category, each with its own eligibility criteria and application requirements.

Workers should plan ahead if they anticipate changes in their living or working arrangements, as switching routes may involve meeting salary thresholds, English language requirements, and sponsorship conditions.

4: Future changes and post-Brexit trends

The Frontier Worker scheme was created as part of the UK’s Brexit settlement with the EU and has no formal end date, but it could be amended or withdrawn by the UK Government. Any such change would likely be influenced by immigration policy priorities, labour market needs, and the UK–EU political relationship.

Holders should monitor Home Office announcements and guidance to ensure they remain aware of any rule changes that could affect their rights or renewal prospects.

5: Tips for compliance and maintaining status

• Keep accurate records of work and travel, including contracts, payslips, and evidence of residence outside the UK
• Plan renewals well in advance of the expiry date
• Check whether any changes in living arrangements or work patterns affect eligibility
• Employers should train HR staff to recognise the permit and manage follow-up right to work checks using the online service
• Consider an immigration strategy if the long-term aim is UK settlement, as this route will not lead directly to ILR

Section Summary
The Frontier Worker permit offers significant flexibility compared with sponsored work routes, but it requires continuous compliance with work and residence requirements. Employers must approach it with the same diligence as other immigration statuses when conducting right to work checks. Workers should incorporate the permit into a broader immigration strategy, particularly if settlement in the UK is a future goal, and remain alert to possible changes in policy that could impact the route’s availability or conditions.

FAQs

Who can still apply for a Frontier Worker permit?

Only EU, EEA, and Swiss citizens who began working in the UK before 1 January 2021 and who continue to meet the eligibility criteria can apply. This includes employed and self-employed individuals, as well as those with retained status due to illness, unemployment, maternity or paternity leave, or vocational training. New cross-border workers who started after this date are not eligible and must apply under a different immigration route.

Can I switch from a Frontier Worker permit to another UK visa?

Yes. You can switch to another immigration route, such as the Skilled Worker visa, provided you meet the requirements for that category. Switching is necessary if you move your main residence to the UK, as you would no longer qualify as a frontier worker.

How often do I need to renew my permit?

If you are currently working, the permit is usually valid for five years. If applying with retained status, it is valid for two years. You can renew indefinitely, provided you continue to meet the eligibility rules. Renewal applications must be submitted before your current permit expires to avoid losing status.

What happens if I lose my job in the UK?

If you become involuntarily unemployed, you may retain your status temporarily under the “retained status” rules. If you worked in the UK for less than a year before unemployment, retention lasts for six months. If you worked for a year or more, retention can continue indefinitely while you are seeking work, provided you remain resident outside the UK and continue meeting the criteria.

Do family members qualify for the same permit?

No. The Frontier Worker permit does not extend to dependants. Family members wishing to live in the UK must apply under a different immigration route, such as the EU Settlement Scheme (if eligible) or another visa category under the Immigration Rules.

Conclusion

The Frontier Worker permit is a distinct post-Brexit immigration route that allows eligible EU, EEA, and Swiss citizens to continue their established pattern of working in the UK while living primarily outside it. It preserves valuable cross-border working rights without the need for sponsorship, minimum salary thresholds, or restrictions on sectors of work.

However, the route is strictly limited to those who began working in the UK before 1 January 2021 and who continue to meet the eligibility conditions. It is not a settlement route and will not, by itself, lead to Indefinite Leave to Remain (ILR). Holders must maintain their “not primarily resident” status, ensure their work remains “genuine and effective,” and renew their permit on time.

For workers, maintaining eligibility depends on accurate record-keeping, keeping proof of work and residence outside the UK, and being aware of how changes in personal circumstances—such as moving residence or losing a job—affect their status. For employers, compliance requires conducting correct right to work checks (primarily via the online service), tracking permit expiry dates, and understanding the legal implications of employing Frontier Workers.

In a changing immigration landscape, the Frontier Worker permit remains an important mechanism for sustaining cross-border economic activity between the UK and the EU. But it should be approached as part of a wider immigration strategy—particularly for those who may eventually want to settle in the UK—while keeping a close eye on any future policy or rule changes that may affect its availability or terms.
