Starting a side hustle in the UK is a practical way to boost your income, pursue your passions, or test the waters of entrepreneurship. With rising living costs in 2025, many people are turning to side businesses to supplement their earnings while maintaining their primary jobs. Whether you want to earn extra money, explore a hobby, or build new skills, a side hustle offers flexibility and opportunity.
What is a Side Hustle?
A side hustle is a part-time job or business you run alongside your main employment. It can range from selling handmade crafts on platforms like Etsy to offering freelance services online. The key is flexibility, allowing you to work around your existing commitments. According to Royal Mail, nearly one in three UK adults has a side hustle, often earning around £200 per month. Side hustles are a way to supplement income, develop skills, or pursue passions that your main job may not fulfill.

There are several reasons to consider a side hustle in 2025:
- Extra Income: Supplement your main job to cover expenses or save for goals like a holiday or wedding.
- Pursue Passions: Turn a hobby into a profitable venture.
- Skill Development: Learn new skills that could benefit your main job or future career.
- Flexibility: Work on your own terms, setting your own hours.
- Potential for Growth: Many side hustles evolve into full-time businesses, as noted by SumUp.
With economic challenges like inflation and rising living costs, a side hustle can provide financial security and peace of mind. AXA UK reports that 62% of UK small business ventures are part-time, highlighting their popularity.

How to Get Started with Your Side Hustle
Starting a side hustle requires careful planning. Here’s a step-by-step guide to help you launch successfully.
Identify Your Skills and Interests
List what you’re good at and what you enjoy. A side hustle that aligns with your passions is easier to sustain. For example, if you love animals, pet sitting might be ideal. If you’re tech-savvy, consider social media management.
Research the Market
Identify demand for your product or service. Use tools like Google Trends or browse social media platforms to see what’s popular. SumUp suggests finding a niche to reduce competition and build a loyal customer base.
Legal Considerations
- Register as Self-Employed: If your side hustle earns more than £1,000 in a tax year, you must register with HMRC as self-employed, as confirmed by The Accountancy Partnership.
- Tax Obligations: File a self-assessment tax return and pay tax on profits above the £1,000 trading allowance. Note that the threshold may increase to £3,000 by 2029, per IPSE.
- Business Insurance: Depending on your side hustle, you may need public liability insurance or professional indemnity insurance, as recommended by Simply Business.
Financial Planning
- Initial Investment: Many side hustles, like freelance writing or tutoring, require minimal upfront costs. Others, like e-commerce, may need investment in inventory or marketing.
- Pricing: Research competitors’ prices to set competitive rates. For example, check platforms like Fiverr for freelance service rates.
- Tracking Finances: Use accounting apps like QuickBooks or spreadsheets to track income and expenses. Crunch emphasizes the importance of tracking to avoid HMRC penalties.
Balancing Your Side Hustle with Your Main Job
Balancing a side hustle with a full-time job requires careful time management:
- Set Specific Hours: Dedicate specific times for your side hustle to avoid conflicts with your main job.
- Establish Boundaries: Inform friends and family about your work hours to minimize distractions.
- Avoid Burnout: Start small and scale up gradually to maintain your energy and enthusiasm.
