How to Start a Business as a Teen in the UK (2025): A Step-by-Step Guide from Side Hustle to Startup

ByInnoVirtuoso

You’ve got ideas, energy, and a phone—what’s stopping you from starting a business before you even finish school? If you’re a teen in the UK, the path to earning your own money and building a brand is more open than you think. In fact, many of today’s best small businesses begin as simple side hustles run from a bedroom, a school library, or a corner of the kitchen table.

This guide walks you through every step—choosing a realistic idea, making it legal, handling taxes, finding startup money, marketing smart, and balancing it all with school and life. I’ll keep it practical, UK-specific, and honest. If you want fluff, this isn’t it. If you want clear steps and real results, you’re in the right place.

Can UK Teens Start a Business Legally? Yes—Here’s How It Works

Let’s start with the rules. In the UK, teens can trade and earn money, but there are age-specific limits you need to understand. You don’t need to “form a company” to get going; most young entrepreneurs start as sole traders.

  • Sole trader basics: You can operate as a sole trader at any age and trade under your own name or a business name. Read the government guidance on becoming a sole trader here: GOV.UK – Set up as a sole trader.
  • Limited company: You must be at least 16 to be a company director. If you’re younger, a parent/guardian would need to be director until you turn 16. Learn more: GOV.UK – Limited company formation and GOV.UK – Appoint company directors.
  • Work rules for under 16s: There are restrictions on hours and types of work, and you may need a work permit from your local council for part-time jobs. Check the rules: GOV.UK – Child employment.
  • Payments and platforms: Many payment processors, marketplaces, and banks require account holders to be 18+. If you’re under 18, you may need a parent/guardian to set up the account or act as an authorised user. Always follow each platform’s terms.
  • Banking: If a dedicated business account isn’t available to you yet, open a separate youth account just for business income and expenses. Keep your money separate to stay organised.

Here’s why this matters: following the right structure early keeps your business legit, protects you from platform bans, and makes taxes much easier down the line. Curious what basic supplies cost right now—label printer, postage scale, or receipt book—See price on Amazon.

Step 1: Pick a Smart, Low-Cost Idea for 2025

Start with an idea that fits your skills, budget, and free time. You don’t need permission to test it—only the discipline to begin.

Great teen-friendly ideas in 2025: – Service-based: tutoring, maths or science revision notes, basic web design, video editing, Canva design, social media content for local shops, lawn care, pet sitting, car washing, computer setup for neighbours. – Product-based: handmade jewellery, candles, art prints, crochet, baked goods (check food safety rules), stickers, digital templates, 3D-printed items, thrifted/vintage reselling (follow platform T&Cs). – Digital micro-businesses: Notion templates, study planners, preset packs for Lightroom/CapCut, e-books, revision guides, niche blogs, newsletter curation.

Focus on problems you can solve quickly. If you can deliver results in days (not months), you’ll learn faster and earn sooner.

Validate Your Idea in a Week

Before you spend money, test demand: 1. Ask 10 people who resemble your target customer what they currently use and what frustrates them. 2. Post a simple “coming soon” page or social post with a clear offer and ask for pre-orders, waitlist sign-ups, or deposits. 3. Run a 48-hour “beta” offer for your first 3–5 customers at a lower price in exchange for feedback and testimonials. 4. Ship the simplest version of your idea. Improve from there.

If nobody buys, the market is speaking—adjust the offer, audience, or price, and try again.

Tools and Gear: What You Actually Need (And What to Skip)

Keep it lean. Your phone can be your studio, HQ, and point-of-sale system. – Photo/video: A phone with a decent camera, a budget ring light, and a simple tripod are enough to look professional. – Audio: If you record voiceovers or TikToks, a clip-on lav mic makes a big difference. – Packaging/shipping: Padded envelopes, tissue paper, thank-you cards, and a small postage scale are essentials if you sell physical goods. – Software: Use free or low-cost tools—Canva, CapCut, Google Workspace, Wave/Excel for bookkeeping, Notion/Trello for tasks.

Pro tip: buy as you grow, not before. If you need beginner-friendly gear like a ring light or mic, Check it on Amazon before you buy locally.

Step 2: Make It Official—Registrations, Taxes, and Banking

Don’t stress—this section is simpler than it looks. You can handle it step by step.

  • When to register with HMRC: If you’re self-employed and earn more than £1,000 from self-employment in a tax year, you need to register for Self Assessment. Details: HMRC – Trading allowance.
  • How to register: Do it online here: GOV.UK – Register for Self Assessment (self-employed). You’ll get a Unique Taxpayer Reference (UTR). Keep it safe.
  • Taxes under 18: The rules are the same as adults—profit is taxable after allowances. If your profit is small, you may pay no income tax, but you must still follow the rules if you pass the reporting thresholds.
  • National Insurance: You don’t pay NI before age 16. After 16, NI depends on your profits and the current thresholds, which change over time—check HMRC guidance each year.
  • Record keeping: Keep receipts, invoices, and mileage logs. It’s the easiest way to file taxes and know your profit. See: GOV.UK – Records for self-employed.

Sole trader or limited company? – Start sole trader: It’s simple and flexible. You can always incorporate later. – Consider a limited company only if you’re 16+, dealing with bigger contracts, or you need limited liability. Otherwise, keep it simple at the start.

Licences, permits, and insurance: – Food businesses must register with the council at least 28 days before trading: GOV.UK – Register a food business. – Selling in public spaces may require a street trading licence—check your local council website. – Product and public liability insurance can protect you if something goes wrong. The Association of British Insurers explains the basics.

Data and privacy: – If you build an email list or process customer data, follow UK GDPR rules. Check whether you need to pay a data protection fee: ICO – Data protection fee. – If you do influencer deals, follow advertising rules: GOV.UK – Social media endorsements.

Banking setup: – If you can’t open a business account yet, use a separate youth account or a parent-supported solution. Never mix personal and business money.

For simple budgeting notebooks and ledgers, you can Buy on Amazon and start tracking from day one.

Step 3: Money—Price Smart, Fund Wisely, Avoid Debt

Price with confidence: – Work out your cost per unit or per hour (materials, packaging, software, fees). – Add your time at a fair hourly rate. – Add a margin (profit) and include taxes/fees. – Check competitor prices, but don’t race to the bottom. You’re selling value, not just a product.

Funding options for teens: – Start small with personal savings or pre-orders. People love supporting a young creator with a clear plan. – Ask family to pre-pay for a limited “launch batch” in exchange for a discount. – Apply for local youth enterprise grants or competitions through your council or school. – The Prince’s Trust helps young people start businesses (typically 18–30) with mentoring and funding pathways: The Prince’s Trust – Start a business. – Join programmes like Young Enterprise for mentorship, networks, and practical experience.

Cash flow rules to live by: – Keep a buffer—aim for one month of expenses. – Pay yourself something, even if small, to stay motivated. – Reinvest most profits in the first six months to scale sustainably.

Taking payments: – Online: Many gateways require you to be 18; under-18s may need a parent/guardian to hold the account according to each platform’s terms. – In person: Consider cash, bank transfer, or a parent-supported card reader if allowed.

Step 4: Marketing and Sales—Get Your First 10 Customers Fast

Brand basics you can do today: – Define a simple offer in one sentence: “I help [who] solve [problem] with [product/service].” – Pick a name you can actually use (search Instagram/TikTok and Companies House for conflicts). – Make a clean logo and social headers in Canva. Don’t overthink it.

Content that sells: – Show the process, not just the product: make short “before/after” or “day-in-the-life” clips. – Use social proof early: ask beta customers for testimonials and permission to use photos/videos. – Share wins, mistakes, and learnings. People support stories, not faceless brands.

Where to sell: – Social DMs and email work great for your first orders. – Marketplaces (e.g., Etsy, eBay) often require sellers to be 18. If you’re under 18, check the platform’s rules and, if allowed, use a parent/guardian account set up in line with their terms. – Local fairs and school events are underrated. You’ll meet real customers and get instant feedback.

Website or not? – Start with a link-in-bio page and a Google Form or simple checkout if platform rules allow. Upgrade to a full site once you have consistent sales. – If you use cookies or collect emails, follow GDPR rules and be transparent. The ICO has simple guides for small organisations.

Messaging that works: – Talk like a human, not a corporate brochure. – Make your first line scroll-stopping and your call-to-action crystal clear. – Answer objections upfront: price, delivery time, quality, and returns.

Step 5: Operations—Deliver Like a Pro (Even If You’re 15)

Systems save you hours and headaches. Set them up early.

  • Orders: Use a simple spreadsheet or Notion board to track orders, due dates, and statuses. Colour-code by stage.
  • Packaging: Keep it neat and on-brand. Include a handwritten note to boost repeat purchases.
  • Shipping: Batch-print labels and schedule Royal Mail drop-offs to save time. Offer tracked shipping for higher-value orders.
  • Returns/refunds: Write a short, clear policy and stick to it. Be fair but protect your time.
  • Quality control: Create a simple pre-ship checklist so mistakes don’t slip through.
  • Safety: If you sell cosmetics, candles, or food, follow the relevant safety and labelling rules. Food businesses must register with the council: GOV.UK – Register a food business.

Keep your books tidy: – Log every sale and expense the same day or once a week. – Back up receipts and invoices in Google Drive. – Set calendar reminders for tax deadlines.

Step 6: Balance School and Business Without Burning Out

Your grades and wellbeing come first. A business should fit around your life—not steamroll it.

  • Time block your week: Assign dedicated slots for school, business, and rest.
  • Use “theme days”: creation Monday, admin Wednesday, delivery Friday.
  • Set customer expectations: publish order cut-offs and response times, especially during exam season.
  • Work in sprints: 45 minutes on, 10 minutes off. Protect your sleep like it’s part of your brand.
  • Ask for help: share customer service or packaging with a parent or friend during busy weeks.

To keep schoolwork and orders organised, Shop on Amazon for planners or wall calendars that actually get used.

Real Stories, Real Lessons: UK Teens Who Built It

  • Jamal Edwards, MBE: Started SB.TV at 15 with a handheld camera and built a media platform that changed UK music. Lesson: Consistency beats gear.
  • Ben Towers: Launched a digital agency at 13 and worked with national brands before most teens sat GCSEs. Lesson: Start with services; upgrade as you learn.
  • Henry Patterson: Founded Not Before Tea at 9, turning a story and characters into a retail brand. Lesson: A strong story is a business asset.

These founders didn’t wait for perfect timing or permission—they started where they were, then levelled up.

Common Mistakes Teens Make (So You Can Avoid Them)

  • Overbuying gear before validating demand.
  • Ignoring platform age rules and getting banned.
  • Mixing personal and business money (nightmare at tax time).
  • Underpricing “because I’m young.”
  • Skipping insurance when selling products to the public.
  • Trying to be on every platform instead of mastering one or two.

Quick-Start Checklist (Use This as Your Launch Sprint)

  • Pick one idea and write a one-sentence offer.
  • Ask 10 potential customers for feedback.
  • Sell a beta version to 3–5 people this week.
  • Open a separate account for business income/expenses.
  • Set up basic records and a simple order tracker.
  • Publish your first three marketing posts or videos.
  • Book your next improvement: better photos, faster delivery, clearer pricing.

Helpful UK Resources

FAQ: Teen Entrepreneurship in the UK

Q: Do I need to pay tax if I’m under 18? A: Yes, if you make a profit above your personal allowance or you need to register due to the trading allowance rules. Age doesn’t exempt you from tax. Learn about the trading allowance here: HMRC Guidance.

Q: Do I need to register with HMRC right away? A: You must register for Self Assessment if your self-employed income is over £1,000 in a tax year. It’s smart to keep records from day one even if you register later in the year.

Q: Can I set up a limited company if I’m 15? A: No. You must be at least 16 to be a company director in the UK. A parent or guardian could act as director until you turn 16 if incorporation makes sense.

Q: Can I sell on Etsy/eBay as a teen? A: Many marketplaces require you to be 18 to hold an account. If you’re younger, check the platform’s terms—some allow parent/guardian involvement.
