Umbrella Company Guide for Architecture Contractors

If you work through an umbrella company, you are usually employed by the umbrella company and paid after deductions such as tax and National Insurance. The important point is simple: understand the pay route before you accept the assignment.

This guide is a practical Architecture Social overview, not legal, tax or financial advice. For current official detail, use GOV.UK guidance and take professional advice where needed.

Watch: choosing who to trust in your job search

This Architecture Social conversation is not tax advice, but it is useful context for thinking carefully about recruiters, intermediaries and who you trust during a job search.

What an umbrella company does

An umbrella company normally sits between the worker, the recruitment business and the end client. The client or agency pays the umbrella company, and the umbrella company pays the worker through PAYE.

• You submit timesheets or approved hours.
• The umbrella company invoices the agency or client.
• The umbrella company processes pay through PAYE.
• Tax, National Insurance and any agreed deductions are taken before net pay.
• You receive a payslip showing how the payment was calculated.

Documents to check first

Before starting, ask for the key information document, assignment details, pay illustration and the umbrella company’s terms. Do not rely on a headline rate without understanding deductions.

• Assignment rate and expected gross pay.
• Employer and employee deductions.
• Umbrella margin or fee.
• Holiday pay arrangement.
• Pension position and any opt-out process.
• Who to contact if the payslip looks wrong.

Listen: recruiters, trust and candidate judgement

This related episode adds a wider conversation about recruiter relationships and judgement, which matters when a role involves several parties between you and the end client.

Checks before you accept an assignment

The key question is not only whether the headline rate looks good. It is whether the net pay, deductions and employment arrangement make sense.

• Does the pay illustration match what you were told?
• Is holiday pay clearly explained?
• Are deductions transparent?
• Does the umbrella company appear on official checks where relevant?
• Is anyone promising unusually high take-home pay?

Payslip checks after you start

Once you are paid, check the first payslip properly. If something does not match the key information document or pay illustration, raise it quickly and keep the paper trail.

• Gross pay and net pay.
• PAYE tax and employee National Insurance.
• Holiday pay treatment.
• Pension deductions or opt-out status.
• Umbrella margin or other agreed deductions.
• Any unexplained payment line, adjustment or reimbursement.

Warning signs

Be careful with any arrangement that looks too good to be true. HMRC has published warnings about schemes that move workers between umbrella companies or promise unusual tax outcomes.

• Take-home pay is much higher than normal PAYE expectations.
• The explanation relies on loans, advances, grants or unusual payments.
• You are moved between companies without a clear reason.
• No one can explain the payslip properly.
• You are pressured to sign quickly before asking questions.

Current GOV.UK guidance to read

For the official position, read GOV.UK guidance on working through an umbrella company, the GOV.UK pay calculator guidance, and the key information document guidance for agency workers paid through umbrella companies.

For recruiters and labour supply chains, GOV.UK also has guidance on responsibilities for employment businesses working with umbrella companies and PAYE rules for labour supply chains from 6 April 2026.

Questions to ask the agency or umbrella company

• Which umbrella company will employ me?
• What is the assignment rate and estimated net pay?
• How is holiday pay handled?
• What deductions will appear on the payslip?
• Who resolves pay issues if the client, agency and umbrella disagree?

Common mistakes

• Comparing roles only by headline day rate.
• Not checking holiday pay until after the first payslip.
• Ignoring an unclear key information document.
• Assuming every umbrella company works in exactly the same way.
• Failing to query unusual deductions quickly.

Architecture Social view

Stephen’s recruiter view is that payroll clarity protects everyone. Candidates should not need to become tax experts, but they should understand who employs them, who pays them and what deductions to expect.
