I’ve been on a bit of a mission lately. You know that feeling when your bank balance could use a little boost, but the idea of throwing yourself into a full-on side hustle just sounds exhausting? Yep, that was me. After a few too many late nights (and plenty of coffee), I pulled together some genuinely doable ways to earn extra money—without turning your life upside down.

No “hustle till you drop” mentality here. Just simple, flexible ideas that actually work—ones I’ve either tried myself or heard about from friends who swear by them.

1. Sell Stuff You Don't Need (and Keep All the Cash)

Clothing rack with colorful outfits, table with handbags, flowers, small figures, and a phone. Sunlit room with plants, cozy and inviting.

Let’s start simple. Got a closet full of stuff you forgot you owned? Platforms like Vinted and eBay have become goldmines. I recently made £150 just clearing out clothes that were collecting dust.

Time commitment? Just an hour or two on a Sunday afternoon.

Pro Tip: Take your photos in natural light, write honest descriptions, and keep your pricing fair. Buyers will come knocking faster than you'd expect.

2. Flip Free Stuff for a Profit

This one’s a little under-the-radar but surprisingly effective. Head over to the “Free Stuff” sections on Facebook Marketplace or Gumtree—you’ll find everything from furniture to appliances, all for free if you can collect.

With a bit of polish and a decent photo, you can relist and resell for profit. My cousin regularly makes £40–£70 flipping freebies—it adds up quickly!

Just a heads-up: some items may need a little cleaning or TLC, so it's perfect if you're a bit handy or at least own some disinfectant wipes.

3. Prolific: Surveys That Don’t Make You Want to Scream

I know—surveys usually feel like a scam or a waste of time. But Prolific is the real deal. It pays actual cash money (not gift cards or weird points), and the surveys are from legit researchers, so they’re usually quite interesting.

Quick note: I’m not affiliated with Prolific. I just use it myself and usually make about £75 a month in real cash, so I thought it was worth mentioning!

4. TikTok Shop Affiliate: Get Paid to Share

If you’re already spending hours scrolling TikTok (no shame), why not make a little money from it? With TikTok Shop’s affiliate program, you can post videos reviewing or showing off products and earn a commission when people buy through your link.

Time commitment: 10–20 minutes per video.A friend of mine earned £300 in her first month just by posting honest, casual videos of products she actually liked.

Don't worry about being perfect. You don't need a ring light and a script. Just be yourself.

5. Sell Your Knowledge: Create Digital Products

Everyone has something they know well enough to teach—yes, even you. Maybe it's a hobby, a career skill, or something friends always ask you for help with.

For me, it’s vocal techniques and performance. I’ve started packaging that into mini-courses and resources. Platforms like Stan Store or Linktree make it easy to sell ebooks, courses, or tutorials.

Great for: Teachers, creatives, coaches, or anyone with a skill to share. Create once, earn repeatedly. It feels amazing to know something you've created can help someone and bring in passive income.

6. Offer Services: You Only Need to Be a Few Steps Ahead

You don’t need a decade of experience to help someone—you just need to be a little further along than they are.

Think about your work or life experience. Could you tutor? Coach? Do admin support? As a teacher and life coach, I realised I could help trainee teachers through their tricky first year, all from home.

Flexible: You can take on as many or as few clients as your schedule allows.Helping people while also earning extra? Feels like a win-win.

7. YouTube Channel: Passion Projects That Pay

A woman smiles at the camera in a cozy room with books and yarn. A laptop displays “DIY Home Decor.” Warm, creative ambiance.

Starting a YouTube channel might feel intimidating, but hear me out. You don't need a massive setup or a viral video. You just need a niche you enjoy, a bit of consistency, and a willingness to learn.

I’ve seen small channels go from hobby to monetised in under six months—just by being real, useful, and relatable. Think: DIY's, book reviews, behind-the-scenes teaching tips or life updates for starters.

Best for: Passion projects you enjoy talking about anyway.

Start where you are. You never know what video might be the one that takes off.

8. Print on Demand: Create Once, Sell Again and Again

Woman with red hair draws in a notebook, surrounded by colorful pens and a laptop. A mug reads "Create & Inspire." Cozy, creative vibe.

This one’s creative and passive. With print-on-demand, you upload your designs to sites like Printful or Printify, and they take care of printing and shipping whenever someone orders.

Design mugs, t-shirts, or totes around seasonal vibes, funny quotes, or niche hobbies—then market them through TikTok or Instagram.

You don't need to be a pro designer - simple, bold ideas can sell really well!
