How to Become a Supply Teacher in the UK Meta

Supply teaching gives you the classroom without the marking pile, the planning nights, or the politics. For many teachers, that flexibility is highly appealing and worth a little uncertainty in terms of working patterns.

Becoming a supply teacher is fairly straightforward if you already have qualified teacher status, and there are routes in even if you don't. Here's how to get started, what you'll need, and how to find work that will suit you.

Key Takeaways

• Most supply teachers have qualified teacher status (QTS), though some cover roles don't require it.

• You can work through a supply agency or directly with schools and local authorities.

• You'll need an enhanced DBS check, references, and the right to work in the UK.

• Choosing the right agency and pay model makes a big difference to both your earnings and your experience.

What qualifications and requirements do you need to be a supply teacher?

The standard route is having qualified teacher status (QTS) (opens in a new tab), which you gain through a degree plus teacher training such as a PGCE. With QTS, you can pick up supply work across state schools.

You don't always need QTS, though. Cover supervisors and unqualified teaching roles take on classes without it, usually with less responsibility and lower pay, and some independent schools hire without QTS too.

Whatever your route, you'll need a few essentials. These are: 

• An enhanced DBS check (ideally registered on the update service)

• Two professional references

• Proof of your right to work

• Identity documents. 

If you've lived abroad, you may also need an overseas police check.

How to become a supply teacher: step by step

Once your qualifications are sorted, the process is quick compared with landing a permanent post.

1. Get QTS, or decide on a cover role if you're not a qualified teacher.

2. Apply for an enhanced DBS check (opens in a new tab) through your school or employer.

3. Prepare your references, CV, and documents so vetting goes smoothly.

4. Register with a supply agency or your local authority supply pool.

5. Complete the agency's compliance and safeguarding checks.

6. Start accepting bookings, from single days to longer placements.

Many teachers register with more than one agency at first, to keep the work coming in while they find their feet.

Supply agency vs local authority: choosing your route

There are two main ways to find supply work, and they suit different people. Most teachers start with an agency.

A supply agency finds work for you quickly and handles the admin, which is ideal if you want regular bookings with little legwork. The trade-off is that agencies take a cut, so your pay can sit below what you'd earn directly.

Going through a local authority supply pool or registering directly with schools often means better pay and pension access, since you're more likely to be paid to scale. The catch is that you'll usually get fewer bookings and have to chase work yourself. Roles in demand, such as for SEND support are often easier to find and can pay more, whichever route you choose.

How to choose a good supply agency

Not all agencies are equal, so it pays to compare a few before you commit. Look at reviews and reputation, how quickly they find work, and the quality of their support.

The most important thing to check is how they pay you. Ask whether you'll be paid to scale or by PAYE rather than through an umbrella company, which can deduct significant fees. Every agency must give you a Key Information Document setting out your pay and deductions before you start, so read it carefully. Supply teachers typically earn somewhere between £120 and £260 a day, depending on experience, region, and how you're employed. Our article on supply teacher pay rates breaks it all down.

Tips for succeeding as a supply teacher

Getting booked once is easy. Getting asked back is where the real job security lies, and it comes down to a few habits.

Walk in with strong behaviour management from the first minute, since pupils test new faces. Stay flexible across subjects and age groups, arrive early to get your bearings, and follow each school's policies on behaviour and safeguarding. Build rapport quickly, leave the class tidy, and the bookings tend to follow.

Supply can be unpredictable, so it helps to look after your wellbeing and keep a "supply bag" of go-to activities for when no work is available.

Frequently Asked Questions

Can you be a supply teacher without QTS?

Yes, in some roles. You can work as a cover supervisor or in an unqualified teaching role without qualified teacher status, usually for less pay. To work as a qualified supply teacher in state schools, though, you'll generally need QTS. Some independent schools are more flexible.

Can early career teachers do supply teaching?

ECTs can do supply work, but there are rules around induction. ECTs can undertake supply work, but short-term day-to-day supply generally does not count towards induction. Check the latest Department for Education guidance on induction requirements before relying on supply work long term

How much do supply teachers get paid?

Supply pay is usually a daily rate, typically around £110 to £260 a day depending on experience, region, and whether you're paid to scale or through an agency. Take-home is lower after tax and any umbrella fees. It's worth comparing offers carefully before accepting.

How long does it take to become a supply teacher?

If you already have QTS and your documents ready, registering with an agency can take just a week or two. The main delay is usually the enhanced DBS check, which can take a few weeks to come through, so apply for it early.

Supply teaching can be a brilliant way to teach on your own terms, whether you want flexibility, variety, or a way back into the classroom. Get your admin in order, choose your route, and you could be teaching within weeks.
