Supply teaching is one of the most flexible careers in UK education. Whether you're a qualified teacher who wants more control over your week, a returner getting back into the classroom, or a career changer testing the waters, supply work lets you choose your schools, your phases and (largely) your hours. This guide walks through exactly how to become a supply teacher in the UK in 2026.
Step 1: Confirm your qualifications
To work as a supply teacher in the UK you typically need Qualified Teacher Status (QTS) — gained through a PGCE, BEd, School Direct or Teach First route — and you must not appear on the DfE's prohibition list. International teachers can apply for QTS via the QTS award route or work in roles that don't require QTS (e.g. cover supervisor or HLTA-style work) while applying.
Step 2: Get safeguarding-ready
Every supply teacher needs an Enhanced DBS check on the Update Service, two professional references covering the last five years, identity documents (passport and proof of address), original qualification certificates, and a clean prohibition check. Reputable agencies like GAC Education will guide you through gathering and verifying every document.
Step 3: Choose your agency carefully
Pick an REC-accredited agency. REC membership signals legal compliance, fair pay practice and proper safeguarding. Ask about AWR (Agency Worker Regulations) compliance, how they pay (PAYE vs umbrella) and whether they offer pension and holiday pay. A good local consultant who knows the schools is worth more than a slightly higher headline rate.
Step 4: Understand the pay
Day-to-day supply rates in 2026 typically range from £130 to £220 depending on phase, key stage, location and experience. Long-term assignments are often paid to scale and become AWR-equivalent (matching a permanent teacher's pay) from week 13. Always check whether the rate quoted is gross or net of holiday pay.
Step 5: Be ready to say yes
The supply market rewards reliability. The teachers who pick up work first are the ones who answer 7am calls, arrive 15 minutes early and leave the classroom the way they found it. Schools talk to each other — and to your consultant. A strong first half-term unlocks a full diary.
