Start with skills and resources you already have, test demand cheaply and avoid paying for a business before you have customers.
Choose a service before a business identity
At £0, the easiest starting point is usually a service: tutoring, admin, writing, gardening, pet care, cleaning, basic design or another skill you already possess. You do not need a logo before you know whether anyone wants the service.
Inventory what you already have
List your skills, equipment, transport, software, qualifications, local knowledge and available hours. Our Opportunity Finder can turn those constraints into a shortlist of ideas.
Define one small offer
Make the first offer narrow enough to explain in one sentence: what you do, for whom, what is included and how long it takes. Narrow offers are easier to price and test.
Find the first customer without paid ads
Start with people or communities where the service is genuinely relevant: local groups that allow it, professional contacts, community noticeboards or established marketplaces. Follow each platform’s rules.
Use free tools carefully
Free email, documents, spreadsheets, calendars and simple portfolio pages can be enough at the start. Do not buy subscriptions because a creator says every side hustle needs a software stack.
Price for the work, not just the visible hour
Include preparation, travel, messages, platform fees and materials when judging whether the work is worthwhile. A nominal hourly rate can look much lower after unpaid time.
Keep records immediately
Record money received and genuine business costs from day one. HMRC’s current guidance includes a £1,000 trading allowance for qualifying gross trading income, with conditions and exceptions. Check GOV.UK as your income grows.
Reinvest only after evidence
If customers are actually paying, then consider whether equipment, insurance, training or software would improve the service. Spend because there is evidence, not because buying things feels like progress.
Know when £0 is unrealistic
Some work legitimately requires insurance, licences, safety equipment, checks or specialist tools. Do not avoid necessary protections simply to preserve the “zero-cost” label.
Build from one repeatable win
The first goal is not to create a huge company. It is to prove that one person will pay for a clearly defined service, deliver it well, learn, and repeat.

Your £0 launch checklist
- Choose one service based on an existing skill or resource.
- Write a one-sentence offer and a simple price or pricing method.
- Create one example of your work if the service benefits from a portfolio.
- Ask for the first customer through a relevant free channel.
- After delivery, record time, costs, feedback and what you would change.
Common questions
Do I need a website?
Usually not for the first test. A clear profile, marketplace listing or simple portfolio can be enough until you know there is demand.
When should I spend money?
When a real constraint is stopping paid work or when a necessary protection is required. Spend against evidence, not the feeling that buying tools makes the venture more legitimate.
