In short: Good one-person businesses use skills you already have, need little stock or equipment and can start part-time. Examples include consulting, freelancing, tutoring, bookkeeping, cleaning, pet care and online selling. Check whether your idea needs a licence, insurance or tax registration before you start.
You do not need a big team or a big investment to start a business. Many successful UK businesses are run by one person. This guide suggests ideas that are realistic to start on your own and explains what to check first.
What makes a business easy to run alone?
Look for ideas that:
- Use skills or experience you already have.
- Need little money up front.
- Can start part-time, alongside a job.
- Do not depend on staff or premises.
- Can grow by raising prices or adding services, not only by working more hours.
Service ideas
- Consulting. Sell your industry experience to businesses that need it short-term.
- Freelance writing, design or development. Work for clients across the UK and abroad.
- Virtual assistant. Manage diaries, emails and admin for busy owners.
- Bookkeeping. Small businesses always need help with records. Check whether you need to be supervised for anti-money laundering purposes.
- Tutoring and coaching. Teach online or in person. Working with children usually needs a background check.
- Social media management. Many local businesses want help but cannot afford an agency.
- Translation. Useful if you speak more than one language well.
Hands-on ideas
- Cleaning for homes, holiday lets or offices.
- Handyman and small repairs. Some trades, such as gas work, need specific registration.
- Gardening and landscaping.
- Dog walking and pet sitting. Some councils require a licence for boarding animals.
- Mobile car valeting.
- Photography for events, products or property.
Online ideas
- An online shop selling products you make or source.
- Print on demand, where a supplier prints and ships items when they are ordered.
- Digital products, such as templates, courses or guides.
- Reselling second-hand or vintage goods.
If you sell to consumers online, you must follow consumer rules on returns, information and pricing.
Before you start
- Test the idea. Talk to potential customers. Would they pay, and how much?
- Check licences and registrations. Food, childcare, animal boarding, alcohol and some trades need them.
- Get insurance. Public liability and professional indemnity insurance are common.
- Decide your structure. Sole trader or limited company.
- Register for tax. Sole traders register for Self Assessment. Companies register for Corporation Tax.
- Keep records from the first day.
Sole trader or limited company?
As a sole trader, setup is quick, but you are personally liable for business debts. Note that from April 2026, many sole traders with income over £50,000 must use Making Tax Digital for Income Tax, and the threshold drops to £30,000 from April 2027.
A limited company is a separate legal entity. Your personal assets are generally protected, it can look more professional to some clients, and you can bring in partners or investors later. It also has more admin: annual accounts, a confirmation statement and a Corporation Tax return.
Which is better for tax depends on your income and circumstances. Ask an accountant before you decide.
Keep your home address private
If you run a business from home, you may not want your address on your website or the public register. A Registered Office Address or virtual office gives you a professional address instead.
