Umbrella Company Costs UK 2026: Fees, Deductions and Take-Home

Umbrella companies are the default route for contractors on inside-IR35 or short contracts — but the deductions confuse almost everyone. Where does the money go between the rate the agency quotes and the pay that lands in your bank? This guide breaks down every umbrella cost for 2026, with a worked example on £400/day.

The one question that matters: assignment rate or pay rate?

Agencies quote umbrella contractors an assignment rate — the total amount paid to the umbrella for your work. That rate has to cover the cost of employing you, not just your wage. Always ask: "Is that the assignment rate or my rate after deductions?" If an agency quotes £400/day as the assignment rate, your gross pay will be meaningfully lower. Get the answer in writing.

The deduction chain, in order

From the assignment rate, deductions come off in this sequence:

1. Umbrella margin — £15–£30 per week. The umbrella's fee for running payroll. This is the only fee the umbrella keeps. Anything much above £30/week deserves a question; anything disguised as something else deserves a challenge.
2. Employer National Insurance — 15% above £5,000 a year. This is the big one, and the most misunderstood: it is met out of the assignment rate, before your gross pay is calculated. It must never appear as a deduction from your gross pay on the payslip — if it does, challenge it immediately.
3. Apprenticeship / Growth & Skills Levy — 0.5% where the umbrella's total pay bill exceeds £3m a year. Most large umbrellas pass this on; smaller ones may not incur it.
4. Your gross pay — whatever is left after 1–3. From this the umbrella deducts:
   • Income tax via PAYE — 20% to £50,270, 40% to £125,140, 45% above (after the £12,570 personal allowance)
   • Employee National Insurance — 8% between £12,570 and £50,270, then 2%
   • Pension — auto-enrolment minimums unless you opt out
   • Student loan, if applicable

Worked example: £400/day

Assume 5 days a week, 46 working weeks a year (allowing for holidays):

• Assignment income: £400 × 5 × 46 = £92,000
• Less umbrella margin (~£25/week × 46): −£1,150
• Less employer NI (15% of ~£87,000 above the £5,000 threshold): −£13,050
• Less levy (0.5% where passed on): −£460
• Gross pay: roughly £77,300
• Less PAYE + employee NI: −£21,500 approx.
• Take-home: roughly £55,800 — about 61% of the assignment rate

Rule of thumb: on a £400/day assignment, roughly £2,000 of weekly assignment income becomes about £1,700 of gross pay before your own tax. The employer NI is doing most of the damage — which is why comparing "rates" without knowing which rate is being quoted is meaningless.

What you get for the deductions

It is not all one-way. As an umbrella employee you have employment rights a limited-company director does not:

• Holiday pay — usually accrued at 12.07% of gross, or rolled up into your pay. Check which your umbrella uses.
• Auto-enrolment pension — the umbrella must enrol you and contribute; you can opt out, but the employer contribution is free money if you stay in.
• Minimum wage protection, sick pay and statutory rights — you are an employee in law.
• Zero admin — no bookkeeping, no VAT returns, no company filings, no accountant's bill.

Red flags: schemes to avoid

• "90% retention" promises. Any umbrella or "loan scheme" promising unusually high take-home is almost certainly a disguised tax-avoidance scheme. HMRC is actively pursuing these, and the liability lands on you.
• Mini-umbrella companies. Fraudulent micro-companies used to exploit the employment allowance and VAT flat rate — if your "employer" keeps changing names, walk away.
• Offshore or non-UK payroll. Legitimate umbrellas operate UK payroll with full PAYE.
• Employer NI shown as a deduction from gross pay. It must come out of the assignment rate, never your gross. A payslip showing otherwise is wrong — or worse.

Choosing an umbrella: a checklist

1. Accreditation — look for FCSA or Professional Passport accreditation.
2. Written reconciliation — assignment rate → gross pay → net pay, before you start. Every deduction named.
3. Margin in plain figures — £/week, not buried in percentages.
4. Same-day or next-day payments and a UK-based support team.
5. Clear holiday-pay policy — accrued or rolled-up, stated upfront.

The bottom line

Umbrella costs are not mysterious once you see the chain: margin, employer NI, levy, then your own tax. The total cost of the route on typical rates is £15–£30/week in margin plus roughly 15% of the rate in employment costs — which is exactly why it suits short, inside-IR35 contracts and not long outside-IR35 ones.
