Teaching is a profession built on expertise, subject knowledge, communication, planning, and the ability to explain complex ideas simply. Those skills translate directly into side hustle income.
The question is not whether a UK teacher can earn on the side, but which options fit around the realities of the job: marking, planning, parents’ evenings, and the kind of tiredness that arrives at 4pm on a Thursday.
This guide covers the best weekend and evening side hustles for UK teachers in 2026 with real hourly rates, an honest look at contract obligations, the tax rules that apply once earnings start to build, and which options protect your energy rather than drain it further.
For a broader overview of how side hustles work in the UK, see our complete guide to UK side hustles.
Can UK Teachers Legally Run a Side Hustle?
Yes, in the vast majority of cases. Teaching in the UK does not come with a blanket prohibition on outside work. Most teachers run side hustles without any issue and without telling their school.
The legal position is straightforward: there is no law in England, Wales, Scotland, or Northern Ireland that prevents employed teachers from earning money outside their contracted hours.
The Working Time Regulations 1998 require that combined working hours across all jobs do not regularly exceed 48 hours per week, but that threshold is rarely relevant for a teacher doing a few hours of tutoring or selling resources online.
What matters is not the law. What matters is your employment contract, your school’s policies, and whether your side hustle creates a conflict of interest. We cover each of those below.
The Contract Question: What You Actually Need to Check?
Before starting any side hustle, spend 15 minutes reading your employment contract. Look specifically for these three types of clause.
Outside Work Restriction Clauses
Some contracts include language such as “employees shall not engage in any other employment without prior written approval.” If yours does, you need written permission before starting.
The process is typically a short email to HR or the headteacher explaining the nature of the work. In practice, most employers’ concern is not whether you earn money elsewhere but whether that additional work creates a conflict of interest or interferes with your primary job.
A Saturday tutoring round or an Etsy shop selling classroom resources is almost never objected to.
If your contract has no such clause which is common in maintained schools using the Burgundy Book or National Conditions of Employment, you are generally free to work outside contracted hours without disclosure.
Conflict of Interest
This is the category that can cause genuine problems. Conflicts arise when your side hustle:
- Directly competes with your school’s commercial interests
- Uses confidential information (pupil data, internal assessments, school materials)
- Could embarrass or bring reputational risk to the school
- Uses school time, equipment, or resources
Tutoring former or current pupils is the most common grey area. Some schools prohibit tutoring their own pupils privately; others require disclosure. Always check this specifically if you plan to tutor students from your school.
Safeguarding and DBS
If your side hustle involves working with children independently, private tuition, childcare, or sports coaching, you need an Enhanced DBS check. If you already have one through your school, check whether it covers the regulated activity you intend to do outside school.
In many cases it does, but the regulated activity category needs to match. Update Check registration at gov.uk is the simplest way to maintain a portable DBS record.
The Practical Rule
Read your contract. If it requires prior approval, request it in writing and keep the response. If it does not, you are free to proceed.
One pattern that causes repeated problems is not the side hustle itself it is people who hid it and were found out when the business became visible online. If in any doubt, disclosure is always the safer path.
The 9 Best Side Hustles for UK Teachers
1. Private Tutoring
Earnings: £25–£65/hour | Time: flexible evenings or weekends | Startup cost: £0
Private tutoring is the most obvious teacher side hustle and, for many, the highest-earning one. Rates in 2026:
- Primary level: £25–£35/hour
- Secondary GCSE: £30–£45/hour
- A-level (Maths, Sciences, English Lit): £40–£65/hour
- 11+ preparation: £35–£55/hour
Platforms that bring clients to you: Tutorful, MyTutor, Superprof, and Tutor.com. Direct word-of-mouth through parent networks remains the fastest-growing source for established tutors.
One note on volume: two sessions per weekend (Saturday morning, Sunday afternoon) at £40/hour earns £160 per weekend roughly £640/month with no additional marketing spend once you have regular clients.
The safeguarding note: if tutoring your own school’s pupils, check your contract first. If tutoring pupils from other schools, a current Enhanced DBS for regulated activity is required by most platforms and most parents.
2. Selling Teaching Resources on Tes
Earnings: £30–£500+/month (passive once built) | Time: 2–4 hours per resource upfront | Startup cost: £0
TES (formerly Times Educational Supplement) is the UK’s dominant marketplace for teacher-created resources worksheets, revision guides, lesson plans, PowerPoints, and unit plans. You set the price; TES takes a commission. Resources typically sell for £2–£6 each.
The passive income case is real but slow to build. A teacher with 50 well-tagged resources across popular GCSE subjects can generate £150–£400/month with no ongoing work. Getting to that point takes 3–6 months of consistent uploading.
What sells best: GCSE revision materials (particularly Maths, English, and Sciences), A-level exam technique guides, schemes of work with editable PowerPoints, and SEND-differentiated resources.
Avoid uploading materials that use third-party copyrighted images or exam questions directly reproduced from past papers. TES will take them down.
The copyright point matters: only upload resources you have created yourself. Do not upload materials that contain reproduced exam questions in full (summary or example use is acceptable), third-party stock images without licence, or your school’s proprietary schemes of work.
ResourceRack is a growing UK-based alternative to TES with lower commission rates worth uploading the same resources to both platforms.
3. Online Exam Marking
Earnings: £8–£18 per script | Time: evenings in May–July (peak season) | Startup cost: £0
Every major UK exam board AQA, OCR, Edexcel, WJEC, Cambridge, recruits teachers as examiners and online markers. Pay is per script (£8–£18 depending on subject and paper length). A dedicated marking session of 4 hours can yield £80–£150 during peak season.
Applications typically open in September–October for the following summer’s exam series. Apply directly through each exam board’s website. You need QTS and relevant subject experience.
The workload is concentrated: May–July for the summer series. Outside that window, standardisation training (paid) and autumn resits add smaller amounts. Many teachers find this fits well as an annual income supplement rather than a regular monthly side hustle.
4. Corporate Training and Workshops
Earnings: £200–£600 per day | Time: weekends and school holidays | Startup cost: £50–£200 (basic materials)
Teachers are professional explainers. That skill has direct commercial value in the corporate sector communication skills training, presentation coaching, leadership development, and sector-specific technical training.
This is a higher-barrier hustle: you need a specific subject expertise that businesses will pay for, and your first client is typically the hardest to find. LinkedIn is the primary platform for corporate training leads. Starting with a clear, specific offer (“presentation skills training for professional services teams”) converts better than “training and development.”
Day rates for independent trainers range from £200 (early career) to £600+ (established reputation). Even two days per term at £300/day adds £1,800 per year with minimal effort.
5. Writing and Editing
Earnings: £15–£50/hour | Time: evenings, fully flexible | Startup cost: £0
Teachers are strong writers. Publishers, educational technology companies, assessment providers, and curriculum developers regularly commission freelance writers with teaching backgrounds. Specific opportunities include:
- Writing CPD materials for teaching organisations
- Authoring revision guides and exam practice books (Pearson, Hodder, CGP)
- Freelance education journalism (TES, Guardian Education, SecEd)
- Writing assessment questions and mark schemes for exam boards
CGP Books, Hodder Education, and Pearson are the largest commission sources for revision book contributors. Rates vary but typically run £25–£40/hour equivalent for structured commission work. Applications are usually via a speculative email with a writing sample.
6. AI Training and Content Quality Work
Earnings: £20–£40/hour | Time: fully flexible | Startup cost: £0
The emergence of AI training platforms has created a genuine income stream for teachers with subject expertise. Platforms including Outlier, Mindrift, Scale AI, and Surge AI pay UK-based subject matter experts to write, review, and rate AI-generated content.
Subject specialists in STEM, History, English Literature, and Law are in particular demand. Work involves tasks like writing example questions and model answers, grading AI responses for accuracy and clarity, and rewriting AI outputs to correct errors.
The hourly equivalent is typically £20–£35 for most tasks. The work is genuinely flexible you pick up tasks at any time, any day, with no fixed schedule. Apply directly through each platform’s website; Outlier is the most accessible entry point for UK applicants.
7. Private Exam Tutoring Intensives
Earnings: £300–£800 per week during holidays | Time: school holidays | Startup cost: £0
A variation on standard tutoring: intensive exam preparation programmes during school holidays. Many secondary teachers run 5-day intensive revision courses in the Easter holiday for GCSE or A-level students, charging £80–£150 per student for the week.
A course of 6–8 students at £100 each generates £600–£800 in a single week without any additional infrastructure. Booking through an established tutoring agency (Explore Learning, TutoringForExcellence) provides student flow; running independently through local marketing keeps more of the fee.
8. Educational Content Creation
Earnings: £50–£500+/month | Time: 2–4 hours per week | Startup cost: £0–£100 (basic recording equipment)
YouTube channels focused on GCSE and A-level subject revision have genuine and growing audiences. A channel covering A-level Economics or GCSE Biology can reach tens of thousands of students. Monetisation through AdSense typically activates at 1,000 subscribers and 4,000 watch hours.
Realistic income from a modestly successful educational YouTube channel (10,000–50,000 subscribers): £150–£800/month from AdSense alone, plus potential sponsorships from revision platforms (Seneca, Save My Exams, Revisely) and affiliate sales.
The timeline is long: 6–12 months of consistent uploading before meaningful income. This is a 2-year project if you approach it seriously, not a quick supplement.
9. Invigilating for Other Schools or Exam Centres
Earnings: £12–£18/hour | Time: exam season (May–July, November resits) | Startup cost: £0
Exam invigilators are in demand across the UK, particularly during the summer exam season. While many schools pay their own staff to invigilate, private exam centres, sixth-form colleges, and independent schools regularly hire external invigilators. JMB Education and Exams Officers across school consortia frequently advertise for sessional invigilators.
Pay is modest but the work is straightforward and fits around existing commitments for teachers who are already free during exam season.

The Tax Rules for Teacher Side Hustle Income
Your teaching salary is handled through PAYE, your school deducts income tax and National Insurance automatically. Your side hustle income sits entirely outside this system. You are responsible for calculating and paying the tax on it yourself.
The key threshold: if your gross side hustle income exceeds £1,000 in any tax year (6 April to 5 April), you must register for Self Assessment with HMRC by 5 October following that tax year.
Your salary will already have used your £12,570 personal allowance in most cases. That means every pound of side hustle profit above the £1,000 trading allowance is taxed at your marginal rate 20% for most teachers, 40% if total income exceeds £50,270.
The practical rule: set aside 25–30% of every side hustle payment into a separate savings account and treat it as tax you have already spent. This prevents the January shock.
For the full breakdown of how the £1,000 threshold works, how to choose between the trading allowance and actual expenses, and what to do if you have already crossed it, see our guide on how the £1,000 tax threshold applies to teacher earnings.
Which Hustle Fits Your Energy Level?
Teaching is cognitively and emotionally demanding. The worst side hustle is one that uses the same type of energy your job does, which is why many teachers burn out from tutoring every evening of the week, even though the hourly rate is excellent.
Use this framework to pick based on your actual situation.
- IF YOU ARE DRAINED AFTER SCHOOL: Choose passive or low-decision work. TES resources, AI training tasks, and invigilating all fit here. You are not required to be “on” you can work mechanically.
- IF YOU HAVE ENERGY ON WEEKENDS BUT NOT WEEKDAYS: Tutoring, intensive courses, and corporate training are ideal. The weekend schedule is predictable and protects your weekday recovery time.
- IF YOU WANT INCOME THAT BUILDS OVER TIME WITHOUT REGULAR EFFORT: TES resources and YouTube are the only genuine passive options. Both require 3–12 months of active building before income becomes meaningful.
- IF YOU WANT THE HIGHEST HOURLY RATE FOR LEAST TIME: Private tutoring at A-level or 11+ level, or corporate training if you have relevant sector expertise. These are the best value for time.
- IF YOU WANT HOLIDAY INCOME ONLY: Exam marking and intensive courses both concentrate into holiday periods — Easter, summer, and Christmas for mock preparation.
Frequently Asked Questions
Do I need to tell my school I am tutoring privately?
It depends on your contract. If your contract has an outside employment clause requiring approval, yes. If it does not, you are generally not required to tell anyone, unless you are tutoring current pupils from your school, in which case check the specific school policy, as some schools prohibit this to avoid perceptions of favouritism or safeguarding concerns.
Can I use school resources for my TES materials?
No. Resources for TES must be your own original work. You cannot use materials developed during paid school time, with school resources, or that incorporate the school’s proprietary schemes of work. Creating original resources at home, in your own time, is fine.
What is the best platform for tutoring in the UK in 2026?
Tutorful and MyTutor are the highest-volume platforms for school-age tutoring in the UK. Tutorful is stronger for in-person local tutoring; MyTutor is entirely online. Both vet tutors and handle payment processing. Going direct (through local Facebook groups, Nextdoor, or word of mouth) removes the platform commission but requires more client acquisition work.
How do I know if my DBS covers private tutoring?
Check your DBS certificate for the regulated activity it covers. For private tutoring of under-18s, you need an Enhanced DBS with a barred list check for child workforce. If your school certificate covers this, it may be portable register it on the DBS Update Service (£13/year) so any client or platform can check its status instantly without a new application.
Is tutoring taxable as soon as I earn the first pound?
No. The £1,000 trading allowance means the first £1,000 of gross tutoring income per tax year is tax-free and requires no registration. Once you cross £1,000 gross across all side hustle activities combined in the tax year, registration for Self Assessment is required. The allowance is per-person, not per-activity.
Are TES resource earnings considered self-employment income?
Yes. Any recurring income from selling resources on TES where you have set up a seller account and are actively selling, counts as trading income for HMRC purposes. It is subject to the £1,000 trading allowance like any other side hustle income.
What to Read Next?
If you are comparing teacher side hustles to other profession-specific options, our guides cover side hustle options for NHS nurses with similar constraints around contracts and registration.
Once your side hustle income starts to grow, the most important next step is understanding how the £1,000 tax threshold applies to teacher earnings, particularly how your salary interacts with self-employment income.
