Which UK Business Structure Should I Choose? (Sole Trader, Partnership, Limited Company)
Choosing the right business structure shapes your tax, personal liability, and how potential customers and investors perceive your company. Here’s a quick comparison:
| Structure | Who It Suits | Pros | Cons |
|---|---|---|---|
| Sole Trader | Freelancers, consultants | Simple, flexible, low setup costs | Unlimited personal liability |
| Partnership | 2+ co-founders, family | Shared responsibilities and skills | Joint liability, divided control |
| Limited Company | Growth-focused start-ups | Limited liability, credibility | More admin, formal compliance |
- Sole traders hold complete control but are personally responsible for all debts or claims.
- Partnerships divide both the rewards and the responsibility—although disputes can arise without a formal agreement.
- Limited companies keep your personal assets isolated from company debts and build trust, but demand strict reporting and more paperwork.

Essential Legal Documents for UK Startups: What You Need and Why
Every new business in England & Wales depends on strong, compliant legal documents. You must have:
- Articles of Association: Sets company rules, including director powers and shareholder rights (required for all limited companies).
- Shareholders’ Agreement: Clarifies founder roles, profit shares, dispute resolution, and exit plans.
- Employment Contracts: Sets the terms for staff employment—salary, notice, IP assignment, confidentiality.
- Consultancy or Freelancer Contracts: Protects both sides if using outside help, defining scope and payment.
- Non-Disclosure Agreement (NDA): Secures confidential information from leaks or misuse.
- Standard Terms & Conditions: Details how you work with customers—covering payment, liability, and cancellations.
These documents protect against disputes and are essential for investor confidence. Using unverified online templates often omits key points under UK law, leading to unenforceable or risky agreements.
Our platform provides downloadable, lawyer-reviewed contracts you can customise in minutes.

| Employment Contract | Notice & Termination Terms | Establishes how employment can end | Prevents unfair dismissal claims and sets expectations |
