EOR vs Umbrella Company

You are running People Ops at a UK consultancy. HMRC has just opened an off-payroll compliance check on a contractor you engaged through their personal limited company in 2023. The inspector wants to see your status determination statement, your reasonable care process, and the contract chain.

You have none of those things in a defensible state.

Your finance director then asks why you cannot put them on the EOR you already use for your two engineers in Berlin. Both arrangements employ the worker. Both invoice you a fee.

On a one-line procurement summary, they look identical. They are not. Choosing the wrong one in a UK IR35 context can leave you with a tax liability in the high five figures plus interest.

This guide explains what each model actually does and where each one is the right answer. Umbrella companies exist because of UK off-payroll legislation. EORs exist because international employment law makes it impractical for a foreign company to hire directly across borders.

What an umbrella company actually is, and the IR35 context that created them

An umbrella company is a UK PAYE employer that sits between a contractor and the end client. The contractor becomes an employee of the umbrella, not of the end client. The umbrella runs PAYE, deducts income tax and both employer and employee National Insurance contributions, and pays the contractor a net salary.

The model exists almost entirely because of IR35 and the 2017/2021 off-payroll working reforms. Before 2017, a contractor decided their own IR35 status. From April 2021 in the private sector, the end client became responsible for determining whether the engagement was inside or outside IR35.

If inside, the fee-payer in the chain had to operate PAYE on the payment. Umbrella companies solved the structural mess by making the contractor a real employee of a real PAYE entity.

The wallet consequence: an inside-IR35 engagement run through an umbrella loses roughly 14 percent of the contract rate to employer NIC and Apprenticeship Levy before the contractor sees a payslip, plus the umbrella’s margin (typically £15 to £30 per week). A contractor on a £600 day rate who used to take home around £450 net through their own limited company outside IR35 will see closer to £330 net through an umbrella at the same day rate. That delta is why contractors push back hard when an engagement gets reclassified.

How the umbrella company employment chain works

The contractual chain runs four entities deep. The end client signs a contract with a recruitment agency. The agency signs a contract with the umbrella.

The umbrella signs an employment contract with the worker. Money flows in the opposite direction: the end client pays the agency, the agency pays the umbrella, the umbrella pays the worker.

The umbrella’s contract with the worker is a real UK employment contract. The worker accrues holiday pay (usually rolled up into the rate), gets statutory sick pay, gets pension auto-enrolment, and gets continuity of employment across multiple assignments. A contractor moving between three different end clients in a year stays employed by the same umbrella throughout, which simplifies mortgage applications and tenancy references.

The workflow consequence for the end client is minimal once the chain is set up: raise a purchase order against the agency, the agency invoices you based on timesheets, and the umbrella handles everything downstream. The friction sits at onboarding: the worker has to sign a new employment contract with the umbrella and understand that their take-home pay will drop versus an outside-IR35 limited company arrangement.

What an EOR does, and how the employment chain differs

An Employer of Record is a legal entity in a country where your company has no presence, which employs a worker on your behalf. You sign a service agreement with the EOR. The EOR signs a local employment contract with the worker.

The worker reports to you for day-to-day work direction but is legally employed by the EOR’s local entity.

The trigger for using an EOR is geographic, not regulatory. You want to hire someone in Germany, Brazil, or Singapore, and you do not have a legal entity there. Setting up a German GmbH costs around EUR 25,000 in fees and takes three to six months.

Hiring through an EOR costs a flat monthly fee (typically £400 to £600 per employee) and takes seven to fourteen days.

The chain is shorter than umbrella: you contract directly with the EOR, no agency in the middle. The EOR’s local entity is the employer of record on the worker’s payslip, on tax filings, and on any employment tribunal claim. You retain operational control; the EOR retains employment control.

Why EORs do not work for UK IR35 contractor engagements

An EOR will happily employ a UK-based worker for you. What they will not solve is your IR35 problem on a contractor who wants to keep contracting. EORs employ workers on full-time or fixed-term employment contracts.

If you push a UK contractor onto an EOR, you have hired them as an employee of a third party, structurally similar to umbrella but typically more expensive and without the contractor-friendly tooling umbrellas have built around weekly timesheets, expense claims, and same-week pay runs.

Geographic scope: where each model operates

Umbrella companies are a UK construct with a small footprint in Ireland and the Netherlands. The model depends on a specific tax framework where contractor-versus-employee status is litigated heavily enough that an intermediary PAYE employer becomes commercially valuable. There is no Spanish umbrella industry, no German umbrella industry, no US umbrella industry, because those countries enforce contractor status differently.

EORs operate globally. The major players cover 80 to 180 countries. The model is fungible across jurisdictions because the underlying problem (foreign company cannot hire directly) repeats in every country.

For any hire outside the UK, Ireland, or the Netherlands, umbrella is not on the menu.

Tax and compliance: PAYE under umbrella vs employer obligations under EOR

Under an umbrella, the umbrella is the UK PAYE employer. The end client’s only compliance obligation is to pass an accurate IR35 status determination statement down the chain. Under an EOR for a UK hire, the EOR’s UK entity is the PAYE employer.

The mechanics are nearly identical: PAYE, NIC, pension auto-enrolment, RTI. The difference is the contractual relationship: the worker is a permanent or fixed-term employee of the EOR, not a contractor working through a PAYE intermediary.

For an EOR hire outside the UK, the compliance picture changes completely. You are now exposed to the host country’s labour law. If the EOR is in France, the worker gets French statutory benefits: 25 days holiday, 13th month pay where applicable, mandatory complementary health insurance.

Expect a fully loaded employment cost in continental Europe of 1.35 to 1.55 times the gross salary, versus roughly 1.15 times in the UK.

Cost comparison: umbrella margin vs EOR fee

Umbrella companies charge a margin of typically £15 to £30 per week, deducted from the contract rate. The bigger cost is employer NIC and Apprenticeship Levy, which runs around 14 percent of the contract value. On a £3,000 weekly contract rate, the worker’s gross salary is closer to £2,580, and net take-home is closer to £1,650 to £1,750 depending on tax code.

EORs charge a flat monthly fee (£400 to £600 per employee per month at scale) or a percentage of salary. For a UK EOR hire on a £75,000 salary, expect a fully loaded annual cost of around £92,000 (£75,000 salary, £10,500 employer NIC and pension, £6,000 EOR fee). The same worker on umbrella at an equivalent contract rate would cost the end client roughly the same in total, but the worker receives less net pay because umbrella structures are optimised for short engagements and rolled-up holiday pay.

The decision driver on cost is rarely the headline fee. A six-week project with a UK contractor is umbrella territory. A two-year role for a UK-based engineer who needs employment-of-record is EOR territory.

When to use an umbrella company vs when to use an EOR

Use an umbrella when: the worker is UK-based, the engagement has been determined inside IR35, the worker wants to keep contracting (weekly timesheets, project-based work, rolled-up holiday pay), and the engagement is short to medium term (under 24 months).

Use an EOR when: the worker is outside the UK and your company has no entity in their country, or the worker is in the UK but you have no UK entity, or the role is permanent and salaried regardless of country.

Use neither when: you have an entity in the worker’s country and the role is permanent (direct hire is cheaper), or when the worker is genuinely independent and an outside-IR35 contractor relationship is defensible.

Decision framework in three questions

• Where is the worker physically located? If outside the UK and you have no entity there, EOR is the only option. If inside the UK, both are on the table.
• What is the engagement shape? Short, project-based, contractor pattern with weekly timesheets points to umbrella. Long, salaried, integrated into the business points to EOR.
• What does the worker want? A contractor pushed inside IR35 usually prefers umbrella because the workflow is contractor-shaped. A new hire who happens to be UK-based usually prefers EOR because the experience is closer to permanent employment.

Get those three answers and the choice resolves itself.

Frequently asked questions

Can an umbrella company employ a worker outside the UK?

Generally no. UK umbrella companies operate UK PAYE and are built around UK employment law. A few have Irish or Dutch sister entities, but the model does not extend to Germany, France, or the US.

For workers outside the UK, you need an EOR, a local entity, or an independent contractor arrangement.

Is an EOR cheaper than an umbrella company for a UK hire?

Roughly equivalent on total cost to the end client, but the cost structure differs. The worker’s net pay is usually higher under EOR for an equivalent contract value because EOR employment is salaried with separately accrued holiday and pension, whereas umbrella rolls holiday pay into the weekly rate.

Does using an umbrella company eliminate IR35 risk for the end client?

Materially yes on the engagement itself, because PAYE is being operated correctly within the chain. Residual risk sits in the status determination process: the end client must still issue an SDS with reasonable care, communicate it to the agency and worker, and respond to challenges within 45 days.

Can a worker move from umbrella to EOR mid-engagement?

Yes, but it is a contract change with friction. The umbrella employment ends, a new EOR employment starts. The worker may lose continuous service for redundancy and parental leave purposes.

Expect two to three weeks of HR work and a frank conversation with the worker about why the change benefits them.

What happens at engagement end under each model?

Under umbrella, the assignment ends and the worker remains employed by the umbrella for future work. Under EOR, ending the engagement means terminating the worker’s employment with the EOR, triggering local notice periods, potential redundancy pay, and contractual termination obligations. EOR exits are slower and more expensive than umbrella exits, which is one reason short engagements lean umbrella.
