Entity vs EOR in United Kingdom: The Decision Framework for Growing Companies

Expanding into the UK often starts with a critical decision: establish a Private Limited Company (Ltd) or use an Employer of Record service. While incorporation through Companies House is relatively straightforward, becoming a compliant UK employer involves far more than registering a company. PAYE administration, workplace pensions, Employer National Insurance contributions, and ongoing HMRC obligations all need to be considered before your first hire.

This guide compares both approaches using UK-specific costs, compliance requirements, and hiring timelines to help you determine which path makes the most sense for your business.

Why companies hesitate before setting up a Private Limited Company (Ltd)

Using an employer of record in the UK is not the only path to compliant hiring, and understanding why companies consider a local entity first makes the comparison more useful. A Private Limited Company (Ltd) gives you full control: your own payroll, your own legal presence, and a permanent footprint in one of the world’s largest economies. For companies planning to hire a large team or establish long-term UK operations, that permanence has real value.

The reality, though, is that running a UK entity means absorbing compliance obligations from day one. Setup is faster than in most countries, but the recurring obligations — payroll, pension auto-enrollment, Employer’s Liability Insurance, and HMRC filing — start immediately and do not scale down if headcount stays small.

Here is what it actually costs to stand up a compliant UK entity:

The registration itself is inexpensive. What grows quickly is the annual compliance overhead: payroll processing, pension administration, HMRC submissions, and accountant fees — all of which apply whether you have one UK employee or 50.

What an EOR does instead

An Employer of Record becomes the legal employer of your UK workers. You retain full day-to-day direction over the work. The EOR manages the employment relationship: contracts, UK payroll, HMRC PAYE registration, auto-enrollment pension, and Employer’s Liability Insurance, all without you needing to incorporate.

This comparison captures the key differences between the two paths:

The EOR vs local entity question ultimately comes down to your timeline, commitment level, and how many people you plan to hire.

The 3 UK-specific compliance facts that change the EOR vs entity calculation

The UK’s compliance environment has three rules that are frequently underestimated by overseas companies. Each one changes the true cost of running your own entity — and explains why many companies choose an EOR even when they plan to grow a substantial UK team.

1. Employer National Insurance contributions

Employer National Insurance (NIC) is a mandatory payroll tax paid by the employer—not deducted from the employee’s salary—at 13.8% of earnings above the secondary threshold of $12,235 (£9,100) per year for the 2024/25 tax year.

For a UK employee earning $81,000 (£60,000) per year, the calculation is:

• Earnings above threshold: $68,715 (£50,900) = $81,000 (£60,000) minus $12,285 (£9,100)
• Employer NIC: 13.8% of $68,715 (£50,900) = approximately $9,482 (£7,024) per year

This is on top of gross salary. It is not negotiable, does not reduce with tenure, and applies to every eligible employee on your payroll. For a team of five employees each earning £60,000, employer NIC alone adds approximately £35,000 to your annual payroll cost before a single benefit is counted.

Companies using an EOR have these contributions managed on their behalf, with full transparency on the total employer of record cost.

2. IR35 off-payroll working rules

IR35 is the UK’s off-payroll working legislation. It targets contractors who operate through a Personal Service Company (PSC), a limited company set up to provide the contractor’s services, but whose working arrangements resemble employment rather than genuine self-employment.

Since April 2021, medium and large private sector companies have been responsible for determining the IR35 status of contractors they engage. If a contractor is assessed as inside IR35, the engaging company becomes liable for PAYE income tax and National Insurance on those fees. The liability sits with you, not the contractor.

Common triggers for an inside IR35 determination include: the contractor working exclusively for your business, using your equipment, being integrated into your team’s day-to-day management, and lacking genuine financial risk on the engagement. Many companies inadvertently fall foul of IR35 when scaling quickly without conducting formal Status Determination Statements (SDS) for each contractor engagement.

3. Auto-enrollment pension obligations

Under the Pensions Act 2008 and associated regulations, UK employers must automatically enroll eligible workers into a qualifying workplace pension scheme. Eligibility begins at age 22 for workers earning above $13,500 (£10,000) per year (2024/25). Enrollment is mandatory; workers can opt out, but the employer must enroll them first.

Minimum contribution rates for 2024/25:

• Employee contribution: 5% of qualifying earnings
• Employer contribution: 3% of qualifying earnings

These obligations activate from your first eligible employee. The Pensions Regulator issues fines starting at $540 (£400) per day for non-compliance, escalating to $13,500 (£10,000) per day for larger employers.

When does a United Kingdom entity make sense?

The financial case for a UK entity strengthens as headcount grows, because per-employee EOR fees eventually exceed the fixed overhead of running your own compliant payroll. That crossover typically happens somewhere between 10 and 25 employees — but only when you factor in all entity costs, not just the Companies House fee.

For companies testing the market, managing UK payroll through an EOR keeps costs variable until you are ready to commit.

Use this decision framework:

Note that permanent establishment risk is a separate consideration. If employees are signing contracts or closing deals on behalf of the parent company, a permanent establishment may already exist regardless of whether you have formally incorporated.

What the Private Limited Company (Ltd) entity carries that the EOR does not

From the moment your UK entity employs its first worker, it inherits a set of statutory obligations that continue for the life of the employment relationship, and in some cases, beyond it. Employment laws in the UK cover all of the following, and compliance with each sits entirely with your entity.

• Payroll compliance. Your entity is responsible for operating PAYE correctly: calculating income tax and National Insurance deductions, submitting Real Time Information (RTI) reports to HMRC with each payroll run, and filing annual employer returns. Errors attract penalties and interest.
• Social contribution management. Employer NIC at 15% above the secondary threshold applies to every eligible employee. There is no exemption for small employers.
• Notice obligations. UK statutory minimum notice is one week for each completed year of service, up to 12 weeks. Most employment contracts specify one to three months’ notice instead. Failure to follow the correct process exposes your entity to wrongful dismissal claims.
• Redundancy consultation. If you make 20 or more employees redundant within 90 days, UK law requires collective consultation with employee representatives for a minimum of 30 days. Failure creates liability for protective awards of up to 90 days’ gross pay per affected employee.
• IR35 status determinations. Your entity must issue a Status Determination Statement (SDS) for every contractor engaged through a PSC and maintain records of all determinations.
• Employer’s Liability Insurance. Legally required for any business with employees in the UK, with minimum cover of £5 million. The Health and Safety Executive can fine employers £2,500 per day for non-compliance.
• Auto-enrollment pension administration. The employee benefits in the UK framework requires you to enroll eligible workers, manage opt-outs, re-enroll every three years, submit pension contributions to your chosen provider, and keep records for six years, from your first eligible hire.
