EOR vs employing through your own entity in the United Kingdom
Reviewed by Mellow Editorial Team, HR & payroll content team
An employer of record (EOR) hires workers on your behalf, handling payroll, tax and compliance under its own legal entity. Employing directly means setting up and running your own UK employer infrastructure. Which makes more sense depends on your hiring volume, timeline and appetite for ongoing admin.
What each model actually involves
With a direct UK entity, you register as an employer with HMRC, run your own payroll under Real Time Information (RTI) rules, submit a Full Payment Submission (FPS) on or before every payday, manage auto-enrolment, handle P60s by 31 May and P11Ds by 6 July, and take on full Employment Rights Act liability. You own the employment relationships entirely.
With an EOR, the EOR becomes the legal employer. Your worker does the work for you, but the EOR's entity sits between you and HMRC. The EOR collects employer National Insurance at 13.8%, processes income tax via PAYE, administers the pension (minimum 3% employer contribution), and deals with statutory leave and sick pay. You pay a service fee that wraps most of those costs together.
Neither model is inherently better. They solve different problems.
Where an EOR has a genuine advantage
Speed. Setting up a UK employer entity, opening a PAYE scheme, registering for auto-enrolment and getting payroll software in place takes weeks at minimum. An EOR can put someone on payroll in days. If you need a hire to start quickly — or you're testing whether a UK presence makes commercial sense — an EOR removes the setup lag entirely.
Low headcount. Running a compliant UK payroll for one or two people is disproportionately expensive if you're doing it yourself. PAYE, RTI submissions, auto-enrolment administration, P60 production and employer liability insurance all carry fixed overhead. An EOR bundles this into a per-head fee that often costs less than the staff time or accountancy fees you'd otherwise spend.
No permanent establishment yet. Some businesses want UK workers but aren't ready to commit to a registered subsidiary. An EOR lets you operate without triggering a formal legal presence — useful during early-stage market entry.
Multi-country hiring. If you're hiring across several countries at once, an EOR (particularly one covering multiple jurisdictions, like how Mellow runs payroll across six countries on one platform) avoids building separate entity infrastructure in each market.
Where your own entity has a genuine advantage
Volume and permanence. Above roughly 10–15 employees in a single country, the per-head EOR fee typically exceeds what it would cost to run payroll directly, either in-house or through a payroll bureau. The fixed cost of your own setup amortises across more people.
Employment relationship clarity. Some roles — senior hires, equity holders, people with access to sensitive IP — work more cleanly under a direct employment contract with your own entity. There's no intermediary in the chain, and the contractual terms are entirely yours to define.
Culture and integration. Practically speaking, an EOR-employed worker is on a different contract template and may receive communications from the EOR about payroll and benefits. For most workers this is invisible, but it can create friction in organisations where tight HR integration matters.
Long-term cost. EOR fees are ongoing. Once you've built the infrastructure for direct employment, the marginal cost of adding employees is lower. If you're confident the UK headcount is permanent and growing, the crossover point comes faster than people expect.
The compliance picture either way
Whether you use an EOR or employ directly, UK employment law applies to the worker. Statutory annual leave (5.6 weeks, or 28 days including bank holidays for a five-day week), auto-enrolment pension rights, Statutory Sick Pay, and family-leave entitlements all remain in force. The Employment Rights Act 2025 has extended day-one rights further, meaning there is less distinction between new starters and established employees than there used to be.
With an EOR, the legal compliance burden sits with the EOR. That is only as reassuring as the EOR's own processes — it's worth asking specifically how they handle RTI submissions, what their process is for statutory payments, and how they manage employee data under UK GDPR.
With direct employment, the compliance burden is yours. That's not a reason to avoid it; it just means you need a payroll process (in-house or outsourced to a bureau) that you've verified is actually working.
How to make the call
Start with two questions: how many UK employees do you expect to have in twelve months, and how quickly do you need to hire?
If the answer is fewer than ten and soon, an EOR is usually the more practical and cost-effective route. If you're planning a meaningful UK operation — a proper team, long-term presence, integration with company equity or benefits — setting up your own entity and running payroll directly will almost certainly serve you better over a three-to-five year horizon.
The honest answer is that most growing businesses use both at different stages: EOR to get started, direct entity once scale justifies it.
