Self-Employment Guides UK — Tax, Business Setup, and Running Your Own BusinessUmbrella Companies Explained — What Contractors Need to Know
How umbrella companies work for UK contractors, what they cost, how pay is calculated, the difference between umbrella and limited company, and what to watch out for.
If you’re contracting through a recruitment agency, you may need to work through an umbrella company. Here’s how they work, what they cost, and whether they’re right for you.
How an Umbrella Company Works
| Step | What happens |
|---|
| 1 | You find a contract role (usually through an agency) |
| 2 | You sign up with an umbrella company as their employee |
| 3 | You do the work at the client site (or remotely) |
| 4 | You submit your timesheet to the umbrella company |
| 5 | The umbrella invoices the agency/client for your work |
| 6 | The agency pays the umbrella company |
| 7 | The umbrella deducts employer NI, employee NI, income tax, pension, and its fee |
| 8 | You receive a net PAYE salary into your bank account |
How Your Pay Is Calculated
| Deduction | Typical amount | Paid by |
|---|
| Your contract rate | e.g. £400/day | Starting point |
| Agency margin | Varies (deducted before you see the pay) | Agency |
| Assignment rate (what umbrella receives) | e.g. £350/day | This is your gross pay before deductions |
| Employer NI (13.8%) | Deducted from your assignment rate | Umbrella (from your gross) |
| Apprenticeship Levy (0.5%) | Deducted from your assignment rate | Umbrella (from your gross) |
| Umbrella margin/fee | £20–£35/week | Umbrella |
| Gross salary | What’s left after employer costs | |
| Employee NI | 8% on earnings £12,570–£50,270 | You |
| Income tax | 20% basic, 40% higher | You |
| Workplace pension (employee) | 5% of qualifying earnings | You |
| Net pay | What you actually receive | |
Example: £400/Day Contract Rate (Inside IR35)
| Item | Amount (per day) | Amount (per month, 22 days) |
|---|
| Assignment rate (after agency margin) | £350 | £7,700 |
| Less employer NI (13.8%) | -£43* | -£946 |
| Less Apprenticeship Levy (0.5%) | -£1.60 | -£35 |
| Less umbrella fee | -£5.70 (£25/week) | -£108 |
| Gross salary | ~£300 | ~£6,611 |
| Less income tax | -£40 | -£880 |
| Less employee NI | -£18 | -£396 |
| Less pension (5%) | -£12 | -£264 |
| Take-home pay | ~£230/day | ~£5,071/month |
*Employer NI is calculated on the gross salary amount above the NI threshold, not the full assignment rate.
Umbrella vs Limited Company
| Factor | Umbrella company | Limited company |
|---|
| Tax efficiency | Lower (full PAYE) | Higher (salary + dividends) |
| Take-home pay (approximate) | ~60–65% of assignment rate | ~70–80% of turnover (outside IR35) |
| Admin | Minimal — submit timesheets | Significant — bookkeeping, accounts, returns |
| Setup | Instant — sign up and start | 1–2 weeks (Companies House, bank account) |
| Running costs | £20–£35/week umbrella fee | £80–£150/month accountant, plus insurance |
| IR35 inside contracts | Simple — umbrella handles everything | Taxed effectively the same as PAYE |
| IR35 outside contracts | Still PAYE — less tax-efficient | More tax-efficient |
| Employment rights | Holiday pay, SSP, pension | None — you’re a director |
| Holiday pay | Accrued (12.07% of pay) | No — you manage your own |
| Pension | Auto-enrolled | Set up your own |
| VAT registration | Umbrella handles it | You handle registration and returns |
| Professional indemnity insurance | Usually included | You arrange your own |
| Best for | Short contracts, inside IR35, low admin preference | Long-term contracting, outside IR35, higher earnings |
When Umbrella Makes More Sense
| Situation | Why umbrella |
|---|
| Contract is inside IR35 | Tax difference is negligible — umbrella is simpler |
| Short contract (under 3 months) | Not worth limited company setup and costs |
| You want zero admin | Submit timesheets and get paid — nothing else |
| Agency requires it | Some agencies only work with umbrellas for inside IR35 roles |
| First time contracting | Try it before committing to limited company |
When Limited Company Makes More Sense
| Situation | Why limited |
|---|
| Contract is outside IR35 | Significant tax savings through salary + dividends |
| Long-term contracting (12+ months) | Setup costs amortised over longer period |
| Higher daily rate (£400+/day) | Greater tax savings at higher earnings |
| Multiple clients | More flexibility in how you manage income |
| You want to build a business | Retained profits, business expenses |
What to Look for in an Umbrella Company
| Feature | What to check |
|---|
| FCSA or Professional Passport accredited | Ensures compliance and independent auditing |
| Transparent fee structure | Fixed weekly fee, no hidden deductions |
| Clear payslips | Should show all deductions including employer NI |
| No tax avoidance schemes | No “loans,” offshore arrangements, or unrealistic take-home promises |
| Pension auto-enrolment | Must be included by law |
| Holiday pay | Should accrue or be included in hourly rate |
| Quick payment processing | How quickly after timesheet submission do you get paid? |
| Insurance included | Professional indemnity and public liability |
Red Flags — What to Avoid
| Red flag | Why it’s dangerous |
|---|
| “Take home 85%+” promises | Almost certainly a tax avoidance scheme |
| Payments described as “loans” | Loan charge scheme — you’ll owe HMRC the tax |
| Offshore payment arrangements | HMRC targets these aggressively |
| Flat-rate expenses without receipts | Non-compliant — you can’t claim expenses you didn’t incur |
| No employer NI on your payslip | They may not be paying it (illegal) |
| Percentage-based fees | Less transparent; can be very expensive at higher rates |
| Pressure to sign quickly | Legitimate companies give you time to review |
| Not FCSA or Professional Passport accredited | No independent compliance verification |
IR35 and Umbrella Companies
| IR35 status | What it means for you |
|---|
| Inside IR35 | You’re taxed as an employee — umbrella company is the simplest route |
| Outside IR35 | You can use a limited company for better tax efficiency |
| Who determines status? | The end client (for medium/large businesses) since April 2021 |
| Can you challenge the determination? | Yes — you have the right to dispute it with the client |
Holiday Pay Through an Umbrella
| Method | How it works |
|---|
| Rolled-up holiday pay | 12.07% added to your hourly/daily rate — no separate paid time off |
| Accrued holiday | Holiday pay builds up — you request paid time off from the umbrella |
| Which is better? | Rolled-up gives you higher pay per day worked; accrued gives you actual paid leave |
