Earning extra income on top of your main job has become increasingly common in the UK. Whether the goal is to pay off debt faster, build savings, or simply have more breathing room, the right side income depends on your skills, time, and circumstances.
Important: Income from side activities is usually taxable. HMRC provides a £1,000 trading allowance per year for casual income. Earnings above this must be declared. Check GOV.UK and consider speaking to an accountant for your specific situation.
Low-effort or passive options
- Selling unused items: Vinted, eBay, Facebook Marketplace. One-off effort, can generate hundreds of pounds from existing possessions.
- Cashback and rewards: using cashback sites and credit cards (paid in full) for existing spending.
- Renting your driveway: apps like JustPark or YourParkingSpace connect you with people needing parking.
- Renting a spare room: the Government's Rent a Room scheme allows you to earn up to £7,500 per year tax-free from a furnished room in your home.
Skills-based income
- Freelancing: offer skills you already have — writing, design, development, marketing, bookkeeping — on platforms like Upwork, Fiverr or directly to clients.
- Tutoring: strong demand for tutors across all subjects and age groups. Platforms like Tutorful connect you with students.
- Consulting: if you have specialist professional knowledge, offering consultancy outside your employed role can be valuable — check your employment contract first.
- Virtual assistance: administrative, scheduling and research tasks for small businesses, often done remotely.
Gig economy options
- Food and parcel delivery: Deliveroo, Amazon Flex, DPD — useful if you have a vehicle or bike.
- TaskRabbit: local handyperson, assembly and moving tasks.
- Care and support work: platforms like Carer.com connect carers with families needing support.
What to consider before starting
- Check your employment contract for any restrictions on outside work
- Understand the tax implications — income above £1,000 per year must usually be declared
- Consider the time cost honestly — is the hourly rate worth it after expenses?
- Start with what you already know, not what requires significant new learning
