Sell Stuff You Don’t Use

Earning potential: £100–£200 in a few days

Let’s start with the easiest win. Go through your wardrobe, tech drawer, or bookshelves. Got clothes you haven’t worn since college? A speaker you never use? That old phone you keep “just in case”? Sell it.

Platforms like Depop, eBay, and Vinted make it super easy to list your stuff, and buyers are out there hunting for vintage fits, electronics, and bargains. Good photos and honest descriptions help it sell faster.

Top tip: You can list your first few items tonight and make your first sale by tomorrow.

Take Paid Surveys

Earning potential: £30–£80 per week

Surveys won’t replace a job, but they’re a great way to chip away at your target while watching Netflix or commuting. Sites like Swagbucks, Branded Surveys, and IPSOS iSay reward you for sharing your opinion with brands that need feedback.

If you join a few panels and stay active, you can stack up around £10–£15 a day. Do it consistently and you could easily make up to £80 within the week.

No experience needed, just a phone and spare time.

Play-to-Earn Mobile Games

Earning potential: £100–£150 per game

Believe it or not, some apps will actually pay you to play mobile games. It’s all part of their marketing to get new players in. If you’re a first-time user, games like Monopoly Go! or Animals & Coins can pay you solid money for reaching milestones.

All you need to do is follow the instructions (like completing a certain level) and cash out your reward. It’s fun, simple, and surprisingly quick money.

Work as a Virtual Assistant

Earning potential: £10–£30 per hour

If you’re good at organising, typing, or staying on top of emails, this one’s for you. Virtual assistants help small business owners, freelancers or busy professionals with admin, research, inbox tidying, and more.

Most gigs are flexible and remote, and platforms like Wing and Fiverr are a great place to start. You can also browse Prograd’s job listings for real VA roles suited to students and beginners.

Work just five hours in a week and you could earn £100 or more, depending on your rate.

Pick Up a Freelance Gig

Earning potential: £25–£150 per project

Got a skill like writing, editing, graphic design, or even social media captions? You can get paid for it. Freelance marketplaces like PeoplePerHour or Fiverr are filled with people looking for help with small one-off projects.

Even if you’re just starting out, you can offer a “micro service” that you can turn around in under an hour, like proofreading a CV, creating a Canva graphic, or editing a video clip.

Nail one or two gigs, and you're already £50–£100 closer to your goal.

👉 Need help finding where to start? Prograd’s freelance section has beginner-friendly gigs waiting for you.

Tutor Online

Earning potential: £12–£25 per hour

If you're confident in a subject like English, Maths, or even Music, tutoring online can be both rewarding and profitable. You don’t need to be a qualified teacher - just good at explaining things clearly and having the right knowledge.

You can teach GCSE or A-Level students through platforms like MyTutor and Tutorful, or even advertise your services locally. Even if you only do 3 or 4 sessions, that’s £60 to £100 in your pocket.

Babysit or Do Local Gigs

Earning potential: £40–£100 per night

If you’ve got experience with kids (or are just naturally great with them), babysitting is a quick way to make money. Most families pay in cash, especially for evening jobs, which means you can get paid instantly.

Even doing two evenings of babysitting this week could get you £80 or more. Check Babysits, local Facebook groups, or ask around your neighbourhood.

Bonus: Prograd also highlights simple offline gigs that can pay just as well -think dog walking, house sitting or tutoring younger kids.

Use Cashback and Quick Task Sites

Earning potential: £50–£120 over a weekend

Sites like Cashback.co.uk pay you for signing up to services, downloading apps, or trying out free trials. It might sound random, but companies pay for referrals, and you get a cut.

Some tasks are as simple as registering for a free trial or completing a sign-up journey. Just don’t forget to cancel any trials you don’t want to keep.

It’s an easy way to earn £50 or more in a single day if you hit a few offers back to back.

👉 Prograd highlights high-paying cashback and offer tasks that you can complete straight from your phone.

Quick Earning Combo That Gets You To £400

Here’s an example of how you could mix and match to hit your goal:

Sell your old clothes and tech for £150

Play one mobile game as a new user for £120

Do two babysitting evenings for £80

Complete some paid surveys and cashback tasks for £50

That’s £400, and you could do it all in a week if you stay consistent and make a plan!
