Stick to What You Can (Legally) Do at Your Age

First things first: age matters. UK laws are fairly specific when it comes to what you can and can’t do before you turn 18. Some sites ask for users to be at least 13 or 16, while others set the bar at 18 – especially if money is changing hands.

That said, many opportunities do allow younger teens to get involved if there’s a bit of parental oversight – you’ll just need Mum or Dad’s help setting up an account or managing payments. Always read the terms and conditions properly (boring, yes, but essential!), and steer clear of anything that seems fishy or too good to be true.

Clear Out, Cash In: Selling Second-Hand Online

Selling your old stuff is hands-down one of the easiest ways to make money online – and no, you don’t need to start flogging vintage records or get heavily into car booting. Grab anything you’ve outgrown or no longer use – clothes, books, tech, even games – and pop them on platforms like:

• Depop: Brilliant for trendy clothes, trainers, or vintage bits and bobs.
• eBay: Bigger marketplace, ideal for everything from old phones to obscure collectibles.
• Facebook Marketplace: Great for local sells (read: fewer postage nightmares).

It’s also a cheeky little way to learn the ropes of basic business: setting prices, writing descriptions, negotiating (politely!), and working out postage. Not to mention it cuts down on landfill – two big sustainable thumbs up.

Dabble in Digital Freelancing or Microtasks

If your teen’s the creative type – decent with words, has a good eye for design, or can navigate Instagram like a pro – freelance gigs could be their ticket in.

Now, I’ll be honest: the big platforms like Fiverr or Upwork do require users to be 18, but with parental oversight, some underage teens can work alongside a family account (check the rules for each site carefully). For younger teens (13+), microtask apps like Swagbucks, Qmee, or even Google Opinion Rewards can pay a little for tasks like surveys or watching short videos. It won’t make you loads, but it’s a good start.

Bonus? These little jobs help build digital confidence – and let’s face it, that’s going to be gold dust on future CVs.

Make and Sell Your Own Digital Products

Here’s where things start to get really fun. If your teen’s got a creative streak – whether that’s designing, music-making, or writing – they can start building digital products and selling them online with very little upfront cost.

Here are a few starter-friendly ideas:

• Etsy or Redbubble: Sell digital art prints, planner pages, or sticker sets.
• Bandcamp/SoundCloud: Musicians can upload original audio, loops, or beats.
• Kindle Direct Publishing: Budding authors can self-publish eBooks.

What’s magic about digital products is the passive income potential – you make it once, and earn a bit every time someone downloads it. Like a vending machine, only cooler.

Start a Channel, Blog or TikTok Hustle

Let’s be honest – most teens are already dabbling in this world. If your young content creator fancies turning their YouTube channel, blog, or TikTok account into something more than just a hobby, it’s worth encouraging (with a side order of online safety advice, naturally).

Platforms like YouTube pay creators via ad revenue, sponsorships and merchandise sales. TikTok and Instagram have their own monetisation paths too, especially for influencers with strong engagement. The key is consistency, creativity – and a clear idea of what the channel’s about (gaming? book reviews? low-budget room makeovers?).

And remember, some platforms like YouTube require creators to be 13+ and may need an adult to set up the AdSense account.

A Quick Note on Safety and Scams

I can’t stress this one enough: always keep an eye out for scams. If it sounds too good to be true (like ‘Earn £500 in a day just by clicking!’), it probably is. Stick to well-reviewed platforms, check for payment protection, logins that look secure, and – for the love of passwords – never give out bank details unless you’re 100% sure who you’re dealing with.

Final Takeaway

Whether you’re flipping those old Harry Potter books on eBay or uploading your first original beat to Bandcamp, making money online as a teen in the UK is more possible now than ever. The trick is to start small, stay safe, and play to your strengths. Whether it’s design, decluttering or digital wizardry, there’s a money-making method to suit every teen…

…and who knows? It might just spark a lifelong side hustle or even a future business. Now that’s growth worth investing in.
