Best Side Hustles for Teachers UK 2026: Realistic Ways to Earn Extra Income

It’s 3:45pm on a Tuesday and you’re marking Year 9 essays while simultaneously wondering how you’ll afford the boiler repair that’s just come in. If that sounds familiar, you’re not alone. The teaching salary in the UK hasn’t kept pace with inflation, and most teachers I know are quietly looking for ways to top up their income without burning out completely. I’ve spent the last three years researching side hustles specifically for teachers, and I’ve learned which ones actually work and which ones are honestly just another time drain you don’t need.

Online Tutoring: The Most Reliable Income Stream

Online tutoring is hands down the most consistent way I’ve seen teachers make proper money on the side. You’re already qualified, you understand how students learn, and you can charge premium rates because you have actual credentials. Platforms like Preply, Chegg Tutors, and Tutor.com let you set your own hours, which is crucial when you’re juggling a full-time classroom job.

Here’s what the money actually looks like. On Preply, experienced teachers typically charge between £15 and £35 per hour, depending on the subject and your experience level. If you pick up just five students doing two sessions a week at £20 per hour, you’re looking at £200 weekly, which is roughly £800 monthly. That’s not life-changing money, but it absolutely covers bills.

The honest limitation here is that you need actual spare time, and if you’re teaching full-time, your evening and weekend availability is your only real window. I’ve watched teachers try to do this while managing full-time teaching and marking, and it works for maybe three months before they hit a wall. You’ve got to be realistic about your energy levels.

VIPKid is another option that pays around £14 to £22 per hour for teaching English to Chinese students. The shifts can be quite early mornings or late evenings, which actually suits some teachers better than evening UK students. The application process is thorough, which I appreciate because it filters out people who aren’t serious.

The real advantage of tutoring is that it uses skills you already have. You don’t need to learn anything new. You just need to be comfortable with online teaching platforms and ideally have a decent webcam and microphone setup (about £50 to £100 total investment).

Selling Lesson Plans and Digital Resources on TES

TES Resources is genuinely brilliant for teachers who’ve already created good teaching materials. Instead of letting your brilliant lesson plans gather dust in your documents folder, you can sell them for actual money. I know teachers earning between £100 and £500 monthly just from resources they’ve already made.

The thing about TES is that you’re selling to other teachers, so you understand your customer perfectly. You know what’s missing from the marketplace because you’ve been frustrated by the gaps yourself. If you’ve created a really good GCSE revision guide for English Literature or a complete unit on fractions that actually works, other teachers will buy it.

Pricing on TES typically ranges from £1.50 to £15 per resource, depending on complexity and comprehensiveness. A detailed scheme of work or a full unit with lessons, assessments, and answer keys could genuinely sell for £8 to £12. If your resource sells just 20 times a month at £5, that’s £100 recurring income for work you’ve already done.

The setup is free, and you’re not even giving TES exclusivity, so you can also sell on Teachers Pay Teachers if you want. Teachers Pay Teachers actually tends to have slightly better sales in my experience, and you can price things a bit higher there.

Where this works best is if you create resources consistently. Don’t just upload three random lesson plans and expect money. Build a portfolio of 15 to 20 solid resources, and then you’ll start seeing decent income. It’s genuinely passive income once you’ve done the work.

Exam Marking and Grading: Steady Work During Holidays

This is probably the easiest side hustle for teachers to jump into because exam boards are actively desperate for experienced markers. OCR, Edexcel, AQA, and WJEC all hire teachers to mark GCSEs, A-Levels, and other qualifications. During peak marking season (usually June to September), you can earn proper money relatively quickly.

Marking pays between £18 and £35 per hour depending on the qualification level and subject. Some teachers I know mark A-Level philosophy essays and earn closer to £40 per hour because it’s specialised. If you work just 10 hours a week during the summer holidays for eight weeks, that’s £1,440 to £2,800 depending on what you’re marking.

The logistics are straightforward. You apply directly to exam boards, go through training (which is thorough but free), and then work from home with an online marking platform. You can usually start with test batches to prove you mark consistently to the standard.

The downside is that the work isn’t evenly distributed throughout the year. You’ll have intense marking seasons, and then nothing for months. It’s not reliable as your sole side income, but as a supplementary hustle alongside tutoring or resources, it’s genuinely useful. You’re also marking papers in your summer holiday, which some teachers genuinely don’t mind because they’d be at home anyway.

I’d recommend having everything set up by April so you’re ready to go when marking season opens. Check the websites for OCR, Edexcel, AQA, and WJEC in early spring.

Creating and Selling Online Courses

This is where things get more ambitious, and honestly, it’s harder than the other options. But I’ve seen teachers make serious money this way, so I think it’s worth including. You’re essentially packaging your teaching expertise into a course that people pay for upfront.

Platforms like Udemy, Teachable, or Skillshare let you create video courses. A course on teaching English as a Second Language, GCSE exam technique, or professional development for teachers could genuinely attract students. Udemy is the most accessible starting point because they handle all the marketing, though they take a significant cut.

Here’s the reality: a quality course needs 10 to 20 hours of video content minimum. That’s 20 to 40 hours of recording, editing, and uploading. If you’re full-time teaching, that’s a serious time commitment. I’ve watched teachers take five to eight months to create a course, working on it nights and weekends.

The income potential is higher than resources, but less predictable. A course on Udemy might earn £500 in month one, nothing in months two to four, then £200 in month five. You’re dependent on people actually finding your course, which means basic marketing skills help.

Teachable lets you build your own platform and charge whatever you want, which is better for higher-priced courses. Teachers charging £50 to £200 for a course on exam technique or professional development can do reasonably well if they market it to their professional network.

My honest take is this works best if you genuinely love creating educational content and don’t mind the upfront investment of time with uncertain payoff. It’s not the quickest route to extra income.

Freelance Writing and Educational Content

Because you’re a teacher, you understand how to explain complex concepts clearly. That’s exactly what educational writers do, and it’s genuinely valuable. Companies creating educational materials, online learning platforms, and EdTech companies need people who can write clearly about educational topics.

Platforms like Upwork and Contently connect writers with clients. You’d typically charge between £0.10 and £0.50 per word for educational content, depending on your experience and expertise. A 2,000-word article about teaching strategies could earn £200 to £1,000.

The barrier here is building a portfolio and getting your first clients. Your first few jobs might pay less while you build credibility. But once you’ve got three to five solid writing samples, you can pitch directly to education blogs, EdTech companies, and training platforms.

Subject matter expertise matters here. If you’re a science teacher, you can write about science education. If you teach business studies, you can write about economics and business topics. The combination of teaching experience and clear writing is genuinely marketable.

The work is flexible and you control your hours completely. Some weeks you take on lots of projects, other weeks you do nothing. It’s less reliable than tutoring, but it’s less demanding than creating online courses.

ESL Teaching to International Students

If you’re a native English speaker (which most UK teachers are), there’s genuine demand for English lessons from international students. This overlaps with online tutoring, but it’s worth treating separately because the rates and platforms are different.

Italki, Verbling, and Tandem are platforms specifically for language learning. You can earn £15 to £25 per hour teaching English to speakers of other languages. Some teachers focus on conversational English, others offer exam preparation for IELTS or Cambridge exams.

The nice thing about ESL teaching is that students are often highly motivated. They’re paying for lessons specifically to improve their English, and they take it seriously. You’ll get fewer cancellations and better engagement compared to some other tutoring.

Many teachers combine this with Preply tutoring and other subjects. So you might teach science and maths to UK students on Preply and English to international students on Italki. The platforms work well together and don’t compete.

Building a good student base takes a few months. Once you’ve got regular students, you can earn consistently. Some teachers report £300 to £600 monthly just from ESL teaching alongside their main job.

Starting a Teacher Blog or YouTube Channel

This is the long-game option. I’m including it because I’ve seen it work, but you need to know it takes time before you see money. You’re essentially building an audience and then monetising them through ads, sponsorships, or selling products.

A YouTube channel about teaching strategies, exam tips, or classroom management could eventually earn money through YouTube Partner Program (which requires 1,000 subscribers and 4,000 watch hours). But that typically takes 12 to 24 months to achieve.

The real money usually comes from sponsorships or selling your own products. A teacher YouTuber with 100,000 subscribers might earn £2,000 to £5,000 monthly through a combination of ad revenue and brand partnerships. But that’s genuinely a two-year project minimum.

I’m going to be honest here: unless you genuinely enjoy creating content and building an audience, this isn’t the side hustle for you. It’s not quick money. But if you’re someone who likes being on camera and has teaching ideas you want to share, it could work.

Starting is free (YouTube costs nothing), but you’ll want decent equipment fairly quickly. A good microphone and lighting setup costs £100 to £300.

Textbook and Curriculum Consulting

Educational publishers, exam boards, and EdTech companies sometimes hire teachers as consultants to review materials, provide feedback, or help develop curriculum. This is more niche than the other options, but it’s genuinely lucrative if you can access it.

You’re typically paid between £25 and £60 per hour for this work. A textbook publisher might hire you to review a draft of teaching materials and provide feedback, which could be 10 to 20 hours of work at £40 per hour. That’s £400 to £800 for relatively focused work.

Getting into this usually requires connections or actively pitching to publishers and EdTech companies. If you’ve created resources that have gained traction, you’re already demonstrating that you understand what teachers and students need. You can approach companies and offer to consult.

The work is irregular, but it tends to pay quite well and is less demanding than tutoring. You’re not teaching, just providing expert feedback on educational materials.

Common Mistakes to Avoid

The biggest mistake I see is teachers trying to do too many side hustles at once. You’ll start tutoring, upload resources to TES, begin marking for exam boards, and start a YouTube channel all in the same month. You’ll be completely burnt out by week three. Pick one or two and build them properly.

Another mistake is underpricing your work. You have a degree, professional experience, and expertise. Don’t charge £5 per hour for tutoring just because you’re worried no one will pay more. Tutors with your qualifications genuinely command £15 to £35 per hour, and clients expect to pay that.

Some teachers create a single resource, upload it to TES, and then wonder why they’re not earning money. Building a portfolio takes work. You need 15 to 20 quality resources before you’ll see meaningful income.

Avoiding proper tax accounting is a mistake too. Any side income is taxable, and you need to report it to HMRC. It’s not complicated (there are excellent resources from HMRC for self-employed people), but ignoring it creates problems. Your teaching salary is PAYE, but your side income might need to be handled differently.

Finally, don’t sacrifice your main job for side income. If tutoring late into the evening means you’re too tired to teach well the next day, you’re hurting yourself. The side hustle should enhance your life, not replace your energy reserves.

Which Side Hustles Work Best Together

Some combinations work better than others. Tutoring and exam marking complement each other nicely because marking is seasonal (summer) and tutoring demand is more consistent throughout the year.

Selling resources and tutoring also work well together. If you’re tutoring students and creating materials, you can sell those materials. It’s like double-dipping on work you’re already doing.

ESL teaching and general tutoring can sit comfortably alongside each other because you can teach different student populations at different times. Morning ESL lessons before school, evening maths tutoring after school.

The combination I wouldn’t recommend is trying to do high-volume tutoring while also marking exams during marking season. That’s just stacking two intensive time commitments, and something will suffer.

Getting Started: A Practical Timeline

If you’re starting from scratch, here’s how I’d approach it. Month one, set up tutoring on one platform (I’d pick Preply). This is straightforward and gives you income quickly. Spend the first month getting students and settling into a rhythm.

Month two to three, create your first batch of resources for TES or Teachers Pay Teachers. Aim for 10 quality resources. You can create these from lesson plans and materials you’ve already developed. Upload them and let them sit while you focus on tutoring.

By month four, you should have a few tutoring students (maybe three to five) and resources uploaded. At this point, you can consider adding exam marking if it’s marking season. If it’s outside marking season, you could explore other options.

By month six, you should have a clear picture of what’s working. Which side hustle is generating income with reasonable time investment? Double down on that. If tutoring is working well, add more students. If resources are selling, create more.

This staged approach means you’re not overwhelmed, and you’re learning what actually works for your situation before committing too much time.

The Reality of Teacher Side Hustles

I want to be honest about something. Side hustles won’t solve systemic salary issues in teaching. They’re genuinely a band-aid. If you’re struggling financially because teacher salaries are too low (which they are), side hustles can help, but they’re not the answer. Some teachers earn an extra £300 to £500 monthly, which is significant but still not fixing the underlying problem.

That said, side hustles do provide some agency. You’re taking control of your income rather than waiting for salary progression. You’re using skills you already have, and in most cases, you’re not starting from zero.

The best side hustles for teachers are the ones that use existing expertise and fit around teaching schedules. Tutoring, resources, and marking tick those boxes. Creating online courses or YouTube channels require more upfront time investment but potentially higher returns later.

I’d pick your side hustle based on your personality. If you like one-on-one interaction, tutoring is for you. If you prefer creating things once and selling them repeatedly, resources or courses work better. If you like variety and focused work, consulting or marking is good. There’s genuinely something here for different teaching personalities.

Tax and Admin Considerations

Any income over £1,000 from self-employment needs to be reported to HMRC through a Self Assessment tax return. This isn’t optional, and it’s not complicated, but you do need to do it. You’ll need to keep records of income and any expenses related to the work.

Expenses you can claim against side income include things like equipment (webcam, microphone, desk for tutoring), software subscriptions, internet costs (proportional to your business use), and office supplies. If you’re spending £100 monthly on a tutoring platform or course software, that reduces your taxable income.

The good news is that a tutor or part-time creator earning £300 to £500 monthly typically owes relatively little tax, especially if you’re claiming expenses. But you still need to report it properly. The HMRC website has excellent guidance for self-employed people, or you can chat with an accountant for about £50 to £100 annually.

Some platforms handle tax reporting for you. Preply, for example, provides 1099 or equivalent documentation. Others don’t, so you need to track income yourself.

Finding Time When You’re Already Exhausted

The reality is you’re already tired from teaching. Finding time for side hustles is genuinely difficult. Here’s what actually works: be specific about when you’ll do it. Don’t say “I’ll tutor when I have time.” Say “I’ll tutor Tuesday and Thursday evenings from 6pm to 8pm.”

During marking season specifically, many teachers give themselves permission to dial back side hustles. Mark for exam boards, earn decent money, then take a break.

Summer is genuinely when you can push side hustles harder. You’ve got more available hours. Some teachers do intensive tutoring during school holidays, knowing they can take a break during term time.

The key is sustainability. A side hustle that burns you out in three months isn’t worth it. You need something that fits into your life without destroying you.

Building a Side Hustle Business Mindset

This might sound simple, but treating your side income seriously makes a difference. Have a separate spreadsheet tracking income. Set a goal (maybe £200 monthly). Check your progress monthly.

Professional presentation matters. If you’re tutoring, have a decent profile picture and clear description of what you offer. If you’re selling resources, use professional covers and clear descriptions. Small touches make a difference in conversion rates.

Customer service matters too. Respond to messages quickly. If someone has a problem with a resource they bought, fix it. Positive word-of-mouth and repeat customers are incredibly valuable for side income.

Don’t be afraid to ask for payment or to increase prices once you’ve got experience. Teachers are often uncomfortable with money conversations, but your expertise is valuable and priced accordingly.

Final Thoughts

The best side hustle for teachers isn’t the one that makes the most money or is the easiest. It’s the one that fits your life, uses skills you have, and doesn’t crush your energy reserves. For most teachers, online tutoring is the entry point because it’s straightforward, reliable, and doesn’t require much upfront work.

I’d honestly recommend starting with tutoring and selling resources. That combination is manageable alongside full-time teaching and can realistically generate £300 to £600 monthly. Add exam marking during summer, and you’re looking at serious supplementary income.

The bigger picture is that side hustles are genuinely helpful but not the solution to teaching salary problems. You’re working more hours to earn what you arguably should be earning in your main job. That’s frustrating but unfortunately realistic. Within that frustration, side hustles do provide some control and extra income, which matters when you’re juggling bills and a full-time job.

Start with one thing. Do it properly for at least three months before adding a second side hustle. Build slowly and sustainably. And be realistic about what you have energy for. Teaching is already demanding work.

Frequently Asked Questions

How much extra can I realistically earn monthly from side hustles?

This varies hugely depending on what you do and how much time you invest. A teacher with five tutoring students at £20 per hour, two sessions each weekly, earns roughly £800 monthly. Someone selling 20 resources at £5 each might earn £100 monthly. A combination of tutoring, resources, and occasional marking could realistically generate £400 to £800 monthly. Don’t expect significant side income without significant time investment.

Do I need special permissions or insurance for side hustles?

You don’t need special permissions in most cases. Check your teacher employment contract, though some schools have clauses about external work. Generally they’re fine with tutoring and selling resources as long as it doesn’t interfere with your teaching job. You don’t typically need special insurance for tutoring from home or selling educational resources, but check your home contents insurance to be sure. Marking for exam boards is explicitly supported by schools because it benefits education.

Which side hustle requires the least time investment?

Selling resources is probably the lowest time commitment once created. You create it once, upload it, and earn money while doing nothing. After the initial creation time (maybe 2 to 5 hours per resource), it’s genuinely passive. Tutoring requires ongoing time commitment but is more reliable income. Marking requires intensive time during specific seasons but pays very well hourly.

What if my school doesn’t approve of side hustles?

Most schools genuinely don’t care about tutoring or selling resources as long as it’s not conflicting with your job. Exam marking is usually supported. Check your contract and ask your head of department or headteacher if you’re unsure. If you’re doing it entirely outside school hours and it doesn’t impact your teaching, it’s usually fine. Be transparent rather than secretive about it.

Is it worth quitting part of my side hustle to focus on the most profitable one?

Yes, but only after you’ve tested what works. If tutoring is bringing in £400 monthly with 8 hours of work weekly, and resources are earning £50 monthly with 2 hours of maintenance, shift focus to tutoring. Conversely, if you’re exhausted from tutoring but resources are generating steady income with minimal effort, lean into resources even if the money is lower. Time and sustainability matter as much as raw income.
