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.

Self-employment tax and business information is based on current HMRC rules. This is not tax or accounting advice. Consider consulting a qualified accountant for your specific circumstances.

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

StepWhat happens
1You find a contract role (usually through an agency)
2You sign up with an umbrella company as their employee
3You do the work at the client site (or remotely)
4You submit your timesheet to the umbrella company
5The umbrella invoices the agency/client for your work
6The agency pays the umbrella company
7The umbrella deducts employer NI, employee NI, income tax, pension, and its fee
8You receive a net PAYE salary into your bank account

When Limited Company Makes More Sense

SituationWhy limited
Contract is outside IR35Significant 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 clientsMore flexibility in how you manage income
You want to build a businessRetained profits, business expenses

What to Look for in an Umbrella Company

FeatureWhat to check
FCSA or Professional Passport accreditedEnsures compliance and independent auditing
Transparent fee structureFixed weekly fee, no hidden deductions
Clear payslipsShould show all deductions including employer NI
No tax avoidance schemesNo “loans,” offshore arrangements, or unrealistic take-home promises
Pension auto-enrolmentMust be included by law
Holiday payShould accrue or be included in hourly rate
Quick payment processingHow quickly after timesheet submission do you get paid?
Insurance includedProfessional indemnity and public liability

Red Flags — What to Avoid

Red flagWhy it’s dangerous
“Take home 85%+” promisesAlmost certainly a tax avoidance scheme
Payments described as “loans”Loan charge scheme — you’ll owe HMRC the tax
Offshore payment arrangementsHMRC targets these aggressively
Flat-rate expenses without receiptsNon-compliant — you can’t claim expenses you didn’t incur
No employer NI on your payslipThey may not be paying it (illegal)
Percentage-based feesLess transparent; can be very expensive at higher rates
Pressure to sign quicklyLegitimate companies give you time to review
Not FCSA or Professional Passport accreditedNo independent compliance verification

IR35 and Umbrella Companies

IR35 statusWhat it means for you
Inside IR35You’re taxed as an employee — umbrella company is the simplest route
Outside IR35You 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

MethodHow it works
Rolled-up holiday pay12.07% added to your hourly/daily rate — no separate paid time off
Accrued holidayHoliday 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
