Understanding the Importance of an Employer of Record
An Employer of Record (EOR) is a third-party organisation that takes on the legal responsibilities of employment on behalf of another business. When a company wants to hire staff in the UK but does not have a registered legal entity there, an EOR provides the corporate infrastructure needed to make that hiring possible. The EOR becomes the official employer on paper, handling employment contracts, payroll, tax filings, National Insurance contributions, pension auto-enrolment, and compliance with UK employment law. The client company retains full control over the employee’s day-to-day work, responsibilities, and performance. This arrangement allows businesses to hire UK-based talent quickly and compliantly without first going through the time and expense of establishing a local subsidiary. For international businesses testing the UK market, scaling a remote team, or responding quickly to talent opportunities, an EOR provides a practical and legally sound alternative to entity formation.
A Practical Guide to Employer of Record in the UK
Hiring across international borders has become considerably more common, but the administrative and legal complexity has not reduced proportionately. A business based in the United States, Germany, or Australia that wants to employ someone in Manchester or Edinburgh faces a specific problem: to employ someone in the UK, you typically need to be a registered UK employer. Establishing that registration from scratch takes months, requires legal support, and generates ongoing administrative overhead that may not be justified for a small or early-stage team.
An EOR resolves this by providing the legal entity the hiring company lacks. The arrangement is well-established in UK law and widely used by international businesses at various stages of their UK presence, from initial market exploration through to teams of significant size.
Understanding how the EOR model works, how it compares to alternatives, and what it costs gives businesses the information they need to decide whether it is the right approach for their situation.
How the EOR Arrangement Works
The employment relationship in an EOR arrangement is divided between two parties, each fulfilling a distinct role.
The EOR is the legal employer. It holds the registered UK entity, enters into the employment contract with the individual, runs payroll, deducts and remits Income Tax and National Insurance through the PAYE system, enrols the employee in a qualifying pension scheme, and ensures that all statutory employment obligations are met. From HMRC’s perspective and under UK employment law, the EOR is the employer.
The client company is the operational employer. It directs the employee’s work, sets objectives, manages performance, determines the role’s scope, and makes decisions about progression and remuneration. The employee works to the client’s agenda, using the client’s systems and processes, even though they are formally employed by the EOR.
The client company pays the EOR a consolidated invoice, typically monthly, covering the employee’s gross salary, employer National Insurance, pension contributions, and the EOR’s service fee. The EOR distributes net pay to the employee, remits statutory deductions to HMRC, and manages all associated administrative tasks.
EOR vs PEO: An Important Distinction
The terms Employer of Record and Professional Employer Organisation are sometimes used interchangeably, but in the UK context, they describe meaningfully different arrangements.
A PEO operates on a co-employment model. It handles payroll and HR administration on behalf of a client, but it assumes the client already has a registered legal entity in the relevant country. The PEO shares employment liability with the client rather than assuming it fully. For a company without a UK entity, a PEO arrangement does not resolve the underlying compliance problem.
An EOR, by contrast, provides the legal entity. It is the sole registered employer for HMRC and UK employment law purposes. A business without a UK presence can use an EOR to hire legally without first establishing a subsidiary.
The practical consequence of choosing the wrong model is significant. A company engaging a PEO without a UK entity is operating without the legal foundation that the arrangement requires, creating exposure to HMRC penalties and leaving the company without the compliance protection it seeks.
UK Payroll and PAYE for International Employers
Any employer in the UK must register with HMRC and operate PAYE. Under this system, the employer calculates and deducts Income Tax from the employee’s wages each pay period and remits the deductions to HMRC, along with National Insurance contributions. The employee receives net pay; the employer handles all the compliance with the tax authority.
For a foreign company without a UK entity, setting up and managing PAYE independently is impractical. It requires a UK bank account, HMRC registration, and the ongoing administrative capacity to manage payroll accurately in accordance with UK rules. Errors carry financial penalties.
Through an EOR, this entire process is managed by the EOR using its own HMRC registration and payroll infrastructure. The client company receives a single monthly invoice in its home currency. The EOR handles all the underlying tax mechanics.
The Total Cost of UK Employment
Gross salary is only one component of the total cost of employing someone in the UK. Two statutory employer obligations add materially to the headline figure.
Employer National Insurance is charged at 13.8% on employee earnings above the secondary threshold. This is an employer cost, not a deduction from the employee’s pay, and it represents a significant addition to payroll budgets. For an employee earning £60,000 per year, the employer’s NI contribution adds approximately £6,900 to the annual cost before any other additions.
Pension auto-enrolment requires employers to contribute a minimum of 3% of the employee’s qualifying earnings into a workplace pension scheme. The employee also contributes, but the employer’s share is mandatory overhead that must be factored into the budget.
Combined, these statutory costs typically add 15%-20% to the gross salary. A business budgeting for a UK hire at £60,000 gross should plan for total employment costs of £70,000-£72,000 before EOR fees are applied.
EOR providers charge either a flat monthly fee per employee or a percentage of the employee’s gross salary. Flat fees provide more predictable budgeting, particularly for businesses hiring senior staff, since they do not increase with salary. Percentage-based fees may appear lower at the entry level but become more expensive as salary increases.
IR35 and Worker Misclassification
A common approach for businesses wanting to engage UK talent without the cost and complexity of employment is to classify the individual as an independent contractor. This avoids employer NI, pension obligations, and statutory employment rights. However, HMRC scrutinises exactly this scenario through the IR35 legislation, which governs off-payroll working.
Under IR35, if the working relationship between a business and an individual resembles employment, the individual must be taxed as an employee regardless of whether they invoice through a limited company. The key indicators are whether the business controls how the work is done, whether the individual could send a substitute, and whether there is an ongoing expectation of work in both directions. A UK-based individual who works full-time for a single client, uses client-provided equipment, works set hours, and follows the client’s direction is likely to be considered a disguised employee under these rules.
The consequences of misclassification include liability for back taxes, interest, and penalties, potentially covering multiple years. Medium and large businesses are responsible for determining IR35 status when they engage contractors.
Engaging a worker through an EOR removes this risk entirely. The EOR employs the individual formally; the relationship is transparently an employment one, and there is no scope for misclassification. For businesses that want to convert existing contractor relationships to compliant employment without establishing their own UK entity, an EOR provides the mechanism to do so.
UK Statutory Employment Rights
UK employment law provides employees with a robust set of protections that are non-negotiable for any employer operating in the country. International businesses accustomed to more flexible employment regimes, particularly those familiar with at-will employment in the United States, should be aware that UK employment law is structured quite differently.
Annual leave entitlement is a minimum of 28 days per year for full-time employees, typically inclusive of the eight public holidays. This is a statutory floor, not a discretionary benefit, and it accrues from the first day of employment.
Statutory Sick Pay is available to employees who are too ill to work, subject to a minimum earnings threshold and a three-day waiting period. The current rate is set by the government and reviewed annually.
Notice periods are a legal requirement rather than a matter of contract discretion. The statutory minimum notice period starts at one week for employees with between one month and two years of service, increasing by one week for each additional year up to a maximum of twelve weeks. Dismissal without following the required notice provisions, or without a fair process for disciplinary or performance reasons, exposes the employer to claims of wrongful or unfair dismissal before an employment tribunal.
An EOR administers all of these obligations on behalf of the client company. The EOR ensures that leave is tracked and paid correctly, that sick pay is calculated and issued in line with the statutory rules, and that any termination process follows the procedures required by law.
Permanent Establishment Risk
A less widely understood risk for international businesses hiring in the UK is the possibility of inadvertently creating a taxable presence, known as a permanent establishment.
UK tax law and the double taxation treaties the UK has with most countries generally define a permanent establishment as a fixed place of business through which an enterprise carries on its business, or as an agent who regularly concludes contracts on behalf of the enterprise. A remote employee in the UK who regularly negotiates and signs contracts on behalf of a foreign parent company may meet this definition, resulting in a portion of the company’s profits becoming subject to UK corporation tax.
Using an EOR creates a structural separation between the foreign company and its UK-based employee. The EOR is the employer, not the foreign company. Provided the employee’s role does not involve entering into contracts on behalf of the foreign company, the EOR arrangement reduces the likelihood that the foreign company will be considered to have a permanent establishment in the UK.
This is not a guarantee, and businesses with employees in client-facing, sales, or contract management roles should seek specific legal advice on the risk of permanent establishment. However, the EOR structure is widely recognised as reducing this exposure compared to a company employing someone directly in a country where it has no registered entity.
EOR vs Establishing a UK Subsidiary
For some businesses, the comparison is not between an EOR and nothing, but between an EOR and establishing a formal UK presence. Both routes can be appropriate depending on the stage and scale of the business’s UK ambitions.
Establishing a UK subsidiary provides the company with full control over its UK employment arrangements, a registered presence that can enter into contracts, open bank accounts, and build a local brand, and the ability to employ at scale without paying a per-employee service fee. The drawbacks are the time required to incorporate and register with HMRC, the cost of legal and accounting support, and the ongoing administrative burden of maintaining a compliant local entity.
An EOR provides immediate operational capability, no setup costs, and no ongoing entity-maintenance overhead. The trade-offs are the per-employee service fee and some limitations on the range of employment arrangements that can be structured, since the EOR is managing standardised compliance rather than fully bespoke arrangements.
For businesses exploring the UK market with a small team, an EOR is typically the more cost-effective and practical starting point. For businesses with a well-established UK operation or a headcount that makes per-employee EOR fees materially more expensive than entity maintenance, incorporation is likely the better long-term position. The two approaches are not mutually exclusive: many businesses begin with an EOR and transition to their own entity as their UK presence grows.
Choosing an EOR Provider
Not all EOR providers operate the same way, and the differences matter practically.
Some providers own their UK legal entity directly. Others operate as aggregators, subcontracting the UK employment to a third-party local partner. Direct ownership means a simpler structure, clearer accountability, and typically faster resolution of payroll or compliance questions. An aggregator model introduces additional layers that can slow communication and obscure responsibility when problems arise.
Pricing transparency is another important consideration. Some providers quote a base fee but charge separately for benefits administration, pension management, or compliance support. Understanding the total cost of the service before engaging prevents unexpected invoices.
Responsiveness and local expertise are material factors in day-to-day operations. A provider with UK-based payroll and HR support who understands the specifics of PAYE, HMRC processes, and employment tribunal risks will manage problems more effectively than one routing queries through a central support team unfamiliar with local nuances.
A Practical Starting Point
For a business that has identified UK talent it wants to hire and is not yet ready to establish a local entity, an EOR provides a fast, compliant, and well-understood route to employment. The arrangement is legally recognised in the UK, widely used by international businesses, and removes the most complex elements of cross-border hiring from the client company’s responsibility.
The starting points are the same regardless of the specific provider chosen: understand the total cost, including statutory contributions and service fees; confirm the provider owns its UK entity directly; verify that the employment contract and payroll arrangements meet UK legal requirements, and ensure the arrangement is structured in a way that manages IR35 and permanent establishment risk appropriately for the role being hired.
From that foundation, the operational relationship can begin quickly, with the EOR handling compliance and the client company focusing on the work it hired for.
