Umbrella 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
