This role does require commitment but the rewards can be very lucrative.

Many new start-ups or small businesses just don’t have the money to pay big agencies for an all singing and dancing website.  This is where you can step in if you know Javascript, CSS, HTML or WordPress.

Getting Started

• Contact local companies directly (drop emails to businesses that have outdated or poor websites).
• Offer different packages such as a basic site, sites with payment options and sites with a booking system).

Potential Prices

4 – Teaching Coding In The UK

If you have a knack for explaining concepts, teaching people can be both a rewarding and lucrative coding side hustle.

Teaching Options

• 1-2-1 Tutoring: Offer sessions to beginners and those considering a change of career.
• Workshops: Work with coding bootcamps or local community centres to offer evening or weekend classes.
• Online Courses: Create content and sell on platforms such as Teachable, Udemy and Skillshare.  These courses can generate passive income long after you first publish them. 

Tutoring Income

5 – Build And Sell Software Tools

This is a good option for coders that like solving problems.  The tools you build don’t need to be massive solutions either.  Smaller tools can sometimes sell better and can be very profitable.

Example Tools

• WordPress plugins
• Chrome extensions
• Mobile apps with in-app purchasing
• SaaS (Software-as-a-Service) micro-products for niche solutions.

Monetising

• Sell on platforms such as CodeCanyon and Gumroad.

This type of activity doesn’t guarantee income but it can definitely create freelance opportunities and add to your CV.

7 – Creating Technical Content

Coding knowledge can be incredibly valuable and often complex.  Having a knack for explaining it in understandable terms can be very valuable. This can lead to making good money for writing and producing clear content for other developers. 

Example Content Roles

• Write guides for blogs and tech companies.
• Teach programming on a YouTube channel.
• Charge to produce a coding and tech newsletter.

Monetising Content

• Companies will pay £100 to £300 per article for good articles.

If you find content writing is your bag, you could consider doing freelance copywriting or self publish a book.

• Prizes vary from £500 to £10,000+.
• Find upcoming events on Hackathons UK and Devpost.
• They are a great opportunity for networking.

9 – Automating Tasks For Business

Businesses (particularly small businesses) waste a lot of time on money carrying out repetitive admin tasks.  Companies will happily pay you if you can automate tasks like report generation, email handling and data entry using JavaScript, VBA, Python etc. 

Examples

• Automating stock ordering systems.
• Create spreadsheet macros that track sales

Earnings

• Depending on the complexity of the project, you can command between £100 and £500 per project.

10 – Sell Templates And Code Snippets

Creating digital products is a fantastic way to earn passive income as once created, they can sell repeatedly.

Example Ideas

Earnings from this are very varied and can range from a few quid a month to thousands. 

TIPS: Balancing Coding As A Side Hustle In The UK

As this article is about coding as a side hustle, you’ll need to plan strategically about utilising your time to the best effect.

• Start slowly: Don’t stretch yourself too much.  In the beginning, do one project at a time.
• Time allocation: Try to allocate a fixed amount of hours each week to your coding hustle.  It will help you keep to a schedule and avoid over committing. 
• Remember your main job: Be sure your contract of employment doesn’t prevent you from taking on freelance work.
• Track finances: Keep your side hustle income separate from other finances as you may need to submit your earnings as self assessment.
• Taxation: Speaking of self assessment, you will be legally required to submit a self assessment to HMRC if you earn over £1,000.

Coding Side Hustle Pitfalls

• Undercharging: Don’t undervalue yourself or your skills.  Cheap rates can lead to too many projects.
• Stick to the brief:  Make sure clients understand what you’re delivering and don’t let them add extras in for free.
• Unreliable clients: Be sure to use contracts and gather deposits.
• Finances: Don’t fritter any income. Don’t forget you may owe the tax man some of it.
