Working for an umbrella company – be aware of the risks

By Ali Jaw ·

Umbrella companies have become increasingly popular with contractors and temporary workers across the UK. On the surface, they offer convenience – someone else handles your payroll, tax, and compliance. However, working through an umbrella company isn’t without risks, and it’s essential to understand what you’re getting into before signing up. As your Worcester-based accountants, we’ve seen both the benefits and the pitfalls, so we’ve outlined the key concerns you should consider.

What is an umbrella company?

An umbrella company is essentially a limited company that employs you as a staff member. Rather than working as a self-employed contractor or setting up your own limited company, you become an employee of the umbrella firm. The umbrella company invoices your client (the recruitment agency or end-user), receives payment, and then pays your salary through PAYE. On paper, this sounds straightforward – but the devil is often in the details.

Hidden costs and reduced take-home pay

One of the most significant risks of umbrella companies is the impact on your actual earnings. Whilst umbrella companies are regulated by HMRC, they typically charge various fees that can substantially reduce your take-home pay.

Common charges include:

  • Umbrella fees: Typically £10–£25 per week
  • Payroll processing fees: Often £5–£15 per week
  • Holiday pay contributions: Some umbrellas withhold a percentage and claim it’s for holiday accrual
  • Admin or compliance fees: Ranging from £2–£10 per week

When you add these together, you could lose £20–£60 per week from your gross pay. Over a year, that’s a potential £1,000–£3,000 reduction. Before signing up, always request a detailed breakdown of all charges and calculate your actual net pay.

Additionally, some umbrella companies operate questionable expense practices. Whilst legitimate expenses can reduce taxable income, HMRC has clamped down on aggressive expense claims. If your umbrella is claiming expenses that don’t genuinely relate to your work, you could face penalties if HMRC investigates.

Employment rights and National Insurance

Working through an umbrella company means you’re technically an employee, which sounds reassuring. However, this status doesn’t always provide the protections you might expect.

Umbrella employees may not receive the same benefits as permanent staff, such as sick pay, pension contributions (beyond the statutory minimum from April 2024), or redundancy payments. Crucially, if the umbrella company goes into insolvency – which does happen – you may not receive your full wages owed.

From a National Insurance perspective, you’ll pay both employee and employer contributions through PAYE on your salary. For the 2024/25 tax year, the employee rate is 8% on earnings between £12,570 and £50,270. This differs from self-employment, where National Insurance contributions are typically lower. Over a year, this can result in significantly higher tax and NI bills.

Compliance and HMRC scrutiny

HMRC has intensified scrutiny of the umbrella company sector in recent years. Whilst many operate legitimately, some engage in aggressive tax avoidance schemes – particularly around expense claims and salary sacrifices.

If your umbrella company is involved in non-compliant practices, you could face complications. HMRC can pursue workers as well as companies for unpaid tax, and penalties can be substantial. Before joining, investigate the company’s track record. Check Companies House records, ask for references from other workers, and question anything that seems overly generous regarding expenses or tax relief.

Should you use an umbrella company?

Umbrella companies aren’t inherently bad – they work well for some contractors, particularly those seeking simplicity and limited responsibility. However, they’re best suited to those taking short-term contracts where the convenience justifies the cost.

For longer-term contracting, establishing your own limited company or operating as a sole trader is often more tax-efficient. You’ll have greater control over your finances, typically lower overall costs, and the ability to retain profits within your company (subject to corporation tax at 19% for profits up to £50,000 for 2024/25).

Final thoughts

If you’re considering an umbrella company, ask difficult questions: What are all the fees? How are expenses handled? What happens if the company fails? Get everything in writing, and run the numbers yourself – don’t rely solely on the umbrella’s calculations.
