Supply teachers — agency PAYE vs umbrella, where the money goes

Decoding the hidden complexities of supply pay

Supply teaching offers fantastic flexibility, but how you actually get paid can be a minefield. When signing with an educational recruitment agency you'll typically be offered a choice between two completely different payment pipelines: Direct Agency PAYE or an external Umbrella Company.

While the umbrella option often advertises a higher daily rate, it uses accounting structures that can leave you with lower net take-home pay than the standard agency contract.

The assignment-rate trap

The single biggest source of confusion is the difference between an umbrella assignment rate and a true gross daily pay rate.

• An agency quoting £180 / day on Agency PAYE means £180 of gross taxable pay. The agency funds its own employer-side taxes and margin from its separate fee.
• An agency quoting £210 / day via an Umbrella Company is not quoting your gross taxable pay. That £210 is the assignment rate sent to the umbrella intermediary.

Before the umbrella calculates your payslip it slices its weekly processing fee (typically £15 – £30) plus all statutory employer-side liabilities out of that assignment pot. Only what's left becomes your gross taxable pay.

The four mandatory umbrella deductions

If you use an umbrella provider, your headline assignment rate is structurally reduced by these four items before your own taxes are even calculated:

1. Employer National Insurance — 15% on earnings above the secondary threshold.
2. Apprenticeship Levy — a 0.5% tax levied on large UK payroll entities; the umbrella, as the legal employer, surcharges this back to you.
3. Umbrella margin — the flat weekly or daily administrative cut kept by the provider.
4. Rolled-up holiday pay adjustment — often factored out of the base rate and re-applied to meet working-time compliance.

Only after those four come off do you reach your actual gross taxable pay, which is then hit with employee Income Tax, Class 1 NI (8%), and any Student Loan repayments. Consequently an advertised £210 / day umbrella rate frequently nets less than £180 / day direct agency PAYE.

Pension — what supply teachers usually miss

Direct agency PAYE supply contracts are not eligible for the Teachers' Pension Scheme — TPS membership is reserved for permanent and fixed-term contracts held directly with a TPS-registered employer. Umbrella structures break the employment chain entirely.

For long-term supply work it's worth requesting a direct contract with the school or local authority (often via Long-Term Supply arrangements) specifically to keep your TPS service continuous — that's worth far more over a career than a couple of pounds extra on the daily rate.

Always audit your Key Information Document (KID)

Under UK employment regulations, recruitment firms are legally required to provide a Key Information Document (KID) before you accept an assignment. The KID must show an exact, step-by-step mathematical breakdown of how your headline daily rate converts down to your final net pay. If a KID doesn't add up on the back of an envelope, that's the document to challenge.
