Working abroad for a UK employer: which rules apply?
A UK contract does not settle your rights abroad. Employment law, tax and social security each have their own test. Here is how to work out your position.
Working abroad for a UK employer does not mean you lose every UK right, and a UK payslip does not protect you by itself. If you are already abroad, start today: save your contract, rota, payslips, messages and a note of the days and hours you worked. Then ask your employer in writing which law covers your job, who is handling tax and social security, and what local work permission you need. Do not wait for a dismissal or the end of a posting to check a deadline.

Which rulebook applies?
For unfair-dismissal protection abroad, Lawson v Serco [2006] and Ravat v Halliburton [2012] require a sufficiently strong connection with Great Britain and British employment law. Recruitment, your base, the employer, contractual terms and actual working arrangements matter. UK payroll alone is not enough.
Your contract can choose English law, Scots law or another legal system. Under Rome I Article 8, that choice cannot remove mandatory protections under the law that would apply without it. Usually this is where, or from where, you habitually work, unless the employment is more closely connected elsewhere. A temporary assignment does not itself change your habitual workplace.
Local rules can also apply to temporary stays. Check work permission, posted-worker notifications, payroll obligations and mandatory workplace standards. Our employment contract guide explains the UK starting point.
Employees, workers and contractors
Employee
- May have unfair-dismissal, redundancy, notice and family-leave rights
- Each right has its own territorial and eligibility conditions
Worker
- May have minimum wage, holiday, rest-break and whistleblowing rights
- Worker status alone does not confer UK unfair-dismissal or statutory redundancy rights
A genuinely self-employed contractor does not get UK employee-only rights such as unfair-dismissal protection or statutory redundancy pay. But a UK “contractor” label does not bind foreign courts, and some protections use wider definitions. See employee, worker or self-employed?
In a Great Britain assignment, the Agency Workers Regulations 2010 normally give equal basic working and employment conditions after 12 qualifying weeks in the same role with the same hirer. Overseas assignments need a separate host-law check.
Do your UK employment rights travel?
For staff moving between countries, the base matters. A London-based engineer sent to Poland for three weeks has a different case from a permanent Prague hire. Recruitment in Leeds, British terms and a contractual return to Leeds support a UK claim during a Prague posting. None is decisive alone. Resigning and joining a Czech subsidiary on local terms usually weakens that connection.
Dismissal and redundancy
As at 1 October 2026, ordinary unfair-dismissal protection in Great Britain normally requires two years’ continuous employment. Service does not have to have been physically worked in Britain. Many automatically unfair reasons, including pregnancy and whistleblowing, do not require that qualifying period. Northern Ireland normally requires one year for ordinary unfair dismissal.
The government’s timetable schedules a six-month qualifying period and uncapped compensatory awards for GB dismissals from 1 January 2027. A GB-protected overseas employee with eight months’ service would meet the scheduled requirement in February 2027, but not the ordinary requirement in November 2026. See unfair-dismissal eligibility and claims.
Statutory redundancy pay normally requires two years’ service. Each completed year attracts half a week’s pay below age 22, one week’s pay at ages 22 to 40, and one and a half weeks’ pay at age 41 or over. Only 20 years count. In Great Britain, the weekly cap is £751 and the maximum is £22,530 for redundancies from 6 April 2026. Those caps should not be assumed to be Northern Ireland’s. There is no general UK entitlement to “severance pay”. Your contract may provide more.
Example: redundancy after a posting
Mara, a care worker, has 10 completed years’ service, including a Finnish posting within GB protection. Six years attract one week’s pay and four attract one and a half weeks. Her £900 weekly pay is capped at £751 for redundancy on 20 October 2026. That gives 12 × £751 = £9,012. The posting has not reset her service. See redundancy pay calculations.
Holiday, minimum wage and sick pay
The statutory holiday minimum is 5.6 weeks, capped at 28 days. For a regular three-day week, 5.6 × 3 = 16.8 days. Check whether the Working Time Regulations cover your overseas arrangement, what your contract promises and which mandatory local rights apply. The unfair-dismissal test does not conclusively answer those questions.
National Minimum Wage requires you to be working or ordinarily working in the UK. HMRC confirms that occasional overseas work can remain covered. A wholly overseas job does not qualify just because the employer is British. The UK rate for workers aged 21 or over is £12.71 an hour from 1 April 2026. Check contractual pay and local minimums abroad. See minimum wage rates and rights.
Statutory Sick Pay needs a separate employment and social-security eligibility check. From 6 April 2026, the weekly rate is £123.25 or 80% of average weekly earnings, whichever is lower, with no lower earnings limit. It starts on the first qualifying day of sickness and lasts up to 28 weeks. An eligible person earning £120 weekly gets £96 weekly SSP. See our sick pay guide.
| Pattern | Employment rights | Tax and social security | Before agreeing |
|---|---|---|---|
| Short business trip | An established GB base normally remains relevant | Check treaty conditions and social-security cover, even for short trips | Permitted activities, notifications and insurance |
| Temporary posting with a return date | Assess the GB connection and mandatory local protections | Check residence, payroll and eligibility for a certificate of coverage | Written posting terms and required registrations |
| Permanent move to a local employer | Local law usually becomes central; UK protection is not automatic | Reassess both countries’ tax and payroll obligations | New contract, immigration status and continuity of service |
Tax: where you work, where you live
There are two different 183-day questions. UK tax residence is one. A treaty exemption for overseas work is another.
Under the Statutory Residence Test, 183 days or more in the UK during a tax year makes you UK-resident. Fewer days does not automatically make you non-resident. Other tests consider homes, work and UK ties. Full-time overseas work can establish non-residence if you meet all the conditions, including fewer than 91 UK days and fewer than 31 UK workdays. Use HMRC’s RDR3 guidance.
UK residents normally pay UK tax on worldwide earnings. Non-residents generally pay UK tax on UK-source income, including UK workdays. A mid-year departure also needs analysis.
The host country may tax work performed there. A treaty’s short-stay exemption normally requires a stay within its day limit, an employer not resident in the host state, and pay not borne by a host permanent establishment. Check the exact treaty. The third condition is not simply that your employer has no overseas establishment.
Example: 150 days working in Germany
Alex, a warehouse worker, is UK-resident for treaty purposes and spends 150 days in Germany. Article 14 of the UK-Germany treaty allows no more than 183 days in any twelve-month period commencing or ending in the fiscal year concerned. If the employer is not German-resident and pay is not borne by its German permanent establishment, the covered salary is taxable only in the UK. If any condition fails, Germany may tax the German work. Double-tax relief is a separate question.
Your employer must normally continue UK PAYE income-tax deductions until HMRC confirms the appropriate treatment. A host payroll may also be needed. Follow HMRC’s overseas employee guidance. National Insurance follows different rules.
Where both countries properly tax the same earnings, treaty or domestic relief may provide a credit or exemption. This does not depend on meeting the short-stay conditions. Keep workday and travel records, payslips and foreign-tax evidence. Relief may need claiming and may not refund all foreign tax.
National Insurance and social security
Income tax and social security follow different agreements. You can be liable to UK income tax while paying social security abroad, or the reverse.
For work in the EU, Gibraltar, Iceland, Liechtenstein, Norway or Switzerland, contributions are usually due where you work. A qualifying temporary posting can retain UK National Insurance for up to two years with an HMRC certificate of coverage, often called a PDA1 or A1. Your employer must normally carry out UK activities and have sent you, or agreed to the temporary overseas work. Employee-requested remote work can therefore qualify.
Apply through HMRC’s guidance. The certificate evidences UK coverage and host exemption for the covered work and period. Multi-country work, Withdrawal Agreement cases and extensions need separate assessment.
Other agreement countries, including Canada, Japan and the USA, have their own posting rules and certificates. The 52-week rule is not a blanket rule outside Europe.
With no relevant agreement, UK Class 1 contributions normally continue for the first 52 weeks if your employer has a UK place of business, you are ordinarily UK-resident and you lived here immediately before starting overseas work. Local contributions may be due simultaneously. Check HMRC’s conditions and the host institution’s rules.
Your employer must assess local registration and business-tax exposure too. A payroll obligation is not the same as a permanent establishment. Article 5 of the UK-Germany treaty considers fixed places of business and habitual authority to conclude contracts. There is no universal safe remote-working period. Get a destination-specific assessment.
Before you go, agree it in writing
- Define the arrangement. Record the country, duties, dates, employing entity, continuity of service and any right to return. See remote work contract terms.
- Record the employment terms. Name the legal system. Confirm pay, currency, allowances, leave and termination terms, then check mandatory local protections.
- Agree the tax arrangements. Identify who assesses residence and treaty relief, runs any host payroll and pays for advice. Record who bears extra tax and delayed relief. Keep separate residence and treaty day counts.
- Confirm social-security cover. Apply for the appropriate certificate or establish the UK contribution period and any simultaneous local liability.
- Check permission and practical cover. Confirm permitted activities, registrations, health cover and insurance. An A1 or health-insurance card does not authorise employment.
Scotland and Northern Ireland
Scotland shares the main GB employment statutes but has separate tribunal arrangements. Breach-of-contract claims retain three months less one day for breaches before 9 November 2026, then move to six months less one day. Scottish income-tax status depends on residence rules, not the employer’s address. Recheck it after an overseas move.
Northern Ireland has separate employment legislation. Ordinary unfair dismissal normally requires one year’s service. The scheduled GB reduction does not automatically change that. Minimum wage rates are UK-wide and SSP’s April 2026 reforms apply in Northern Ireland too. Do not import GB paternity-leave changes, tribunal deadlines or redundancy caps. See Northern Ireland’s employment rules, nidirect and the Labour Relations Agency.
What is in force and what is scheduled?
- In force. Sick pay and leave changes
SSP waiting days and the lower earnings limit were removed. Paternity leave and unpaid parental leave became day-one rights in Great Britain. Pay eligibility remains a separate question.
- In force. Most GB tribunal time limits increase
For problems arising on or after this date, the usual limit is six months less one day. Earlier problems generally retain the old limit. Scottish breach-of-contract claims change on 9 November 2026. Some claims already had six-month limits.
- Scheduled. GB unfair-dismissal changes
The published timetable specifies six months’ qualifying service and uncapped compensatory awards for dismissals from this date. Fire-and-rehire protections are also scheduled for January. Future dates remain subject to parliamentary processes.
If your employer has cut shifts, withheld pay or threatened your job, save the messages and ask for help. Acas can explain early conciliation; Citizens Advice and a local law centre can help you weigh up next steps. Talk to your union: Unite in hospitality and logistics, UNISON in care and health, USDAW in retail, or GMB and IWGB where they organise your workplace. Use HMRC’s minimum-wage complaint route for underpayment, the GLAA to report exploitation in agriculture or food processing, the HSE for serious safety risks, and the EHRC for discrimination. A report is not a substitute for protecting a tribunal deadline.
Questions people ask
Can my employer cut my pay because I moved abroad?
The move alone does not authorise a pay cut. Check the contract and posting variation for location-based pay or allowances, plus mandatory local rules. See remote work and pay changes.
Does UK payroll preserve all my UK rights?
No. Payroll is one fact in the employment-law analysis. Holiday, minimum wage, statutory payments, tax and social security have separate tests.
Will I be double-taxed if PAYE continues?
You may initially face deductions in both countries. Relief for tax properly charged on the same earnings may require a claim. It is separate from the short-stay exemption.
Does an A1 certificate let me work from Spain or France?
No. It confirms social-security coverage, not immigration permission. Check your permitted activities and any posting notifications.
Am I protected if I invoice a UK client from abroad?
Invoicing does not settle employment status. Check the actual relationship and local law. A UK IR35 assessment does not determine foreign employment status.
