Umbrella Company Margin Explained

What the umbrella margin is, what's included, typical costs, and how to compare umbrella companies fairly.

Last updated: April 2026

What is the Umbrella Margin?

The umbrella company margin is the fee the umbrella company charges for its services. It is the amount the umbrella retains from your assignment rate to cover its costs and profit — above and beyond the employer NI and apprenticeship levy which are statutory obligations.

The umbrella margin is how the company gets paid for running your payroll, maintaining compliance, and providing insurance cover. It is the only variable cost in umbrella pay that you can actually shop around for.

Unlike most service fees, the umbrella margin is usually charged as a fixed weekly or monthly amount (e.g. £25/week or £100/month), not as a percentage of your earnings. This means higher earners pay proportionally less in margin as a share of their total pay.

What's Included in the Margin?

A fully compliant, FCSA-accredited umbrella company's margin should cover:

Payroll processing (PAYE, NI, pension)

Employer's National Insurance

Auto-enrolment pension administration

HMRC RTI submissions

Statutory sick pay / maternity processing

Public Liability Insurance (usually £10m+)

Professional Indemnity Insurance (usually £5m+)

Employers' Liability Insurance

FCSA or industry body accreditation fees

Payslip generation and distribution

Holiday pay accrual and payment

Watch out: Some umbrella companies charge extra for same-day BACS, invoice queries, or have minimum term contracts. Always read the terms carefully before signing.

Margin Cost Comparison

The real cost is lower than the headline margin because it reduces your taxable income (assuming 40% tax rate for higher earners):

How to Compare Umbrella Companies on Margin

When comparing umbrella companies, don't just look at the weekly margin. Check:

Is professional insurance included? — PL and PI cover can cost £30–£60/month elsewhere
Is there a minimum term or exit fee? — Good umbrella companies don't lock you in
What is the payment frequency? — Weekly vs monthly can affect your cash flow
Are there charges for fast payment? — Same-day BACS should be standard, not extra
Is the company FCSA or APSCo accredited? — This provides compliance assurance
What is the customer service like? — You'll need responsive support when issues arise
