Quick Answer
A side hustle is any income-generating activity you do alongside your main job, ranging from freelance skills like writing or design, to selling products online, tutoring, driving for a delivery platform, or renting out a spare room. The best side hustle for you depends on your existing skills, how much time you have available, and whether you want a flexible, low-effort option or something with longer term growth potential.
Freelance and Skill-Based Side Hustles
- Freelance writing or editing, suited to strong written English and research skills
- Graphic design or social media content creation, suited to a creative or visual skillset
- Web development or coding, suited to technical skills and often commands higher rates
- Virtual assistance, handling admin, scheduling, or email management for small businesses
- Tutoring, either academic subjects or specific skills like languages or music
Selling and Reselling
- Reselling secondhand clothing or items through platforms like Vinted, which charges individual sellers no fee, or eBay for a wider range of items, using Royal Mail’s free collect-from-home service to avoid extra trips
- Mystery shopping, visiting shops or using services in person and submitting a review in exchange for payment or reimbursement
- Cashback sites and apps, earning a small percentage back automatically on purchases you would be making anyway
- AI training and evaluation work, a fast-growing 2026 category where platforms pay for rating and improving AI model responses, with subject-matter experts in fields like law, medicine, or engineering often earning at the higher end
- Print on demand or handmade products, suited to those with a creative or crafting interest
- Dropshipping, selling products online without holding stock yourself
- Car boot sales or local marketplace flipping, buying undervalued items and reselling for profit
Asset and Space-Based Side Hustles
- Renting out a spare room through a lodger arrangement or short-term letting platform
- Renting out a driveway or parking space in areas with high parking demand
- Renting out equipment or tools you already own but use infrequently
Delivery, Driving and Task-Based Work
- Food or parcel delivery, offering flexible hours around existing commitments
- Rideshare driving, suited to those with a suitable vehicle and available evenings or weekends
- Task-based platforms, covering odd jobs like flat-pack assembly, gardening, or moving help
Choosing the Right Side Hustle for You
| Priority | Best Suited Side Hustle Type |
|---|---|
| Minimal time commitment | Renting out space, reselling unused items |
| Using an existing professional skill | Freelance writing, design, development, or tutoring |
| Flexible hours around a main job | Delivery driving, task-based platforms |
| Longer term growth potential | Selling products, freelance client work, content creation |
Practical Things to Sort Out Before Starting
- Check your main employment contract for any restrictions on outside work or conflicts of interest
- Register as self-employed with HMRC if your side hustle income goes beyond the trading allowance threshold
- Keep basic records of income and expenses from the start, rather than trying to reconstruct them later
- Set aside a portion of side hustle income for tax, since it is not deducted automatically as it would be from salaried pay
How Much Time Should You Realistically Commit?
Being honest about available time prevents a side hustle from becoming an added source of stress rather than a helpful extra income. Many people start with just a few hours a week, testing an idea before committing more time once they see whether it is genuinely worthwhile and enjoyable alongside their main job.
Frequently Asked Questions
Do I need to tell my employer about a side hustle?
Check your employment contract, since some include clauses about outside work, particularly where there is a potential conflict of interest.
Do I need to pay tax on side hustle income?
Generally yes once you exceed the trading allowance threshold, and registering as self-employed with HMRC is usually required at that point.
What is the easiest side hustle to start with no money?
Freelance skill-based work, such as writing, virtual assistance, or tutoring, typically needs little to no upfront investment beyond your existing skills and time.
How many hours a week does a side hustle usually need?
This varies widely, but many people start with a few hours a week and adjust based on how much time they realistically have and how the side hustle develops.
Can a side hustle turn into a full-time business?
Yes, many full-time businesses started as side hustles, though this usually requires a deliberate decision to scale up once the idea proves genuinely viable.
