If you’re considering a side hustle and you’re full time employed, then you aren’t alone. Many full time workers are looking for side hustles to increase their income. 

Whether it’s for more disposable income, paying off debts or just giving themselves some financial breathing space, increasingly people are looking for the best side hustles for full-time workers. 

Balancing a full-time job and a side hustle can be challenging, but for many, the rewards far outweigh the effort. If you’re curious about adding a little extra to your monthly income, here’s a look at some of the best side hustles for full-time workers.

Why start a side hustle?

Let’s face it: most of us could use a bit more money in our pockets. Whether you’re saving up for something big, looking to cover monthly expenses, or just want a new challenge, a side hustle can be a flexible way to improve your financial situation.

The eight best side hustles for full-time workers

Here is our list of eight side hustles for full-time workers

1. Freelance writing or graphic design

If you have a knack for words or a creative eye, freelancing in writing or graphic design can be an ideal side hustle. Websites like Upwork and Fiverr offer plenty of opportunities, ranging from writing blog posts to creating logos. And because these gigs are often project-based, you can choose work that fits around your main job.

Pros: 

Flexible hours, no commuting, and good rates as you build experience.

Cons: 

Competition is tough, especially for newcomers, and work can dry up if demand falls.
‍

2. Online tutoring

Tutoring is a fantastic side hustle for anyone who has expertise in a particular subject. If you’re good at maths, languages, science, or even musical instruments, sites like Tutorful or MyTutor can connect you with students. Online tutoring allows you to teach from home, making it easier to manage around a full-time job.

Pros: 

High hourly rates and rewarding work.

Cons:

It may require a set time commitment, and you’ll need strong teaching skills.
‍

3. Ecommerce - selling online 

If you’re a bit entrepreneurial, setting up a small online shop could be just the ticket. Whether it’s selling handmade crafts on Etsy, vintage finds on eBay, or dropshipping through Amazon, ecommerce can be a lucrative side hustle. 

Keep in mind, though, it requires research to understand demand and competition in your chosen niche. We'd recommend checking out our article 'how to sell online like a pro' if you're just getting started.

Pros: 

Scalable and can turn into a primary business.

Cons: 

It takes time to set up and may require an upfront investment.

4. Delivery driving or ridesharing

If you’re up for a bit of driving, becoming a delivery driver for services like Deliveroo, Uber Eats, or even a rideshare driver for Uber can help you earn some extra cash. This is ideal if you have a car, a bit of free time in the evenings or weekends, and enjoy being on the move.

Pros: 

Flexible hours and tips.

Cons: 

Vehicle wear and tear, fuel costs, and dealing with traffic.
‍

5. Blogging or a YouTube channel

Starting a blog or YouTube channel is a slower burner but can generate passive income over time. Find a topic you’re passionate about, such as personal finance, fitness, or cooking, and create engaging content regularly. With time, you can monetise through ads, sponsorships, or even selling your own products.

Pros: 

Creative freedom and long-term income potential.

Cons: 

Requires consistency and time to build an audience; it may take months or even years to see a return.
‍

6. Pet sitting or dog walking

If you’re an animal lover, pet sitting or dog walking can be an enjoyable way to make extra money. Apps like Rover or Pawshake connect you with local pet owners who need reliable help. It’s also a great option for those who want to spend more time outdoors, get some exercise, and enjoy time with animals.

Pros:

Flexible hours and enjoyable work.

Cons: 

Can be physically demanding and requires a good level of responsibility.
‍

7. Remote customer service

Many companies hire part-time remote customer service agents to assist their customers over the phone or online. These jobs often have flexible shifts, so you can work a few hours here and there after your regular job. Customer service experience isn’t always required, but good communication skills are essential.

Pros: 

Reliable income and steady work.

Cons:

Dealing with customer complaints can be challenging, and shifts may not always be convenient.
‍

8. Social media management

If you know your way around Instagram, Facebook, and X (Twitter), consider offering social media management services to small businesses. This role involves creating posts, engaging with followers, and sometimes managing ad campaigns. Many business owners are willing to pay for someone who can help them grow their online presence without needing to hire a full-time employee.

Pros: 

Creative work and flexible hours.

Cons: 

It can be time-consuming and requires staying up-to-date with trends.

Tips for managing a side hustle with a full-time job

Starting a side hustle is exciting, but balancing it with your full-time work can be tricky. Here are a few tips to keep you on track:

Set boundaries:

Decide how much time you can realistically devote to your side hustle and stick to it. Burning out will only impact both your main job and your new venture.

Prioritise organisation:

Use tools like calendars or project management apps to keep track of deadlines and commitments.

Be honest with yourself:

Not every side hustle is going to suit your schedule or lifestyle. Pick something you genuinely enjoy or can manage easily on the side.

Stay compliant with your employer:

Check your employment contract for any clauses that might restrict outside work, and if needed, have an open conversation with your employer.

Save for taxes:

Remember that side hustle income is usually taxable. Setting aside some money each month will prevent a surprise tax bill down the line.

Is a side hustle right for you?

Side hustles aren’t for everyone. They require time, commitment, and often involve navigating a bit of a learning curve. However, for full-time workers looking to boost their income, gain new skills, or pursue a passion project, the right side hustle can be well worth the effort. Whether you’re freelancing, delivering food, selling online, or walking dogs, there’s a side hustle out there for almost everyone.

Just remember, side hustles should enhance your life, not add stress to it. Take your time, explore different options, and find something that works for you. With the right approach, you can make that extra income without sacrificing your work-life balance.

Don’t forget about Self Assessments

One important thing to keep in mind when starting a side hustle is that any additional income might mean you’ll need to file a Self Assessment tax return. In the UK, the tax deadline for self-employed or side hustle income is January 31st each year. If you’re earning money outside of your main job, you’ll need to report it. If you aren't sure whether you'll need to complete a Self Assessment, be sure to check out our article here which covers the circumstances that require a Self Assessment.

Filing a Self Assessment for the first time can feel a bit overwhelming, but planning ahead can make it manageable. We'd recommend checking out our Self Assessment knowledge section as it's packed full of helpful tips and guides, including completing your first Self Assessment. Setting aside a percentage of your side hustle income each month for tax and keeping records of your earnings and expenses will make things much easier when tax season rolls around. If you're unsure of your obligations or how much tax to set aside, getting professional advice can save time, money, and hassle.
