Running a business in the UK isn’t just about sales, marketing, or cash flow — it’s also about staying on the right side of the law. From contracts to data protection, understanding key legal obligations is vital if you want to grow with confidence.

Here are 10 legal essentials every small business owner should know.

1. Employment Contracts: Get Them in Writing

Every employee must have a written statement of employment terms. Make sure contracts clearly outline duties, hours, pay, notice periods, and restrictive covenants. Ambiguity can cause disputes later on.

---

2. Non-Disclosure Agreements (NDAs)

Whether you’re pitching to investors or discussing ideas with potential partners, NDAs can protect your intellectual property. A properly drafted NDA can prevent others from using your ideas or confidential information.

3. Data Protection and GDPR Compliance

All businesses that process personal data must comply with the UK GDPR and Data Protection Act 2018. You may also need to register with the ICO as a data controller. Failing to do so can result in significant fines.

4. Transparent Pricing and Terms & Conditions

Since 2018, the SRA Transparency Rules have required solicitors to publish prices for certain services. Even if you’re not in the legal sector, clear terms and conditions are essential for managing customer expectations and reducing disputes.

5. Handling Client Monies Safely

If your business holds money on behalf of clients (for example, deposits or advance fees), strict rules may apply. In the legal sector, this is governed by the SRA Accounts Rules — and breaches can be serious.

6. Claims Management Costs

If your business offers claims management services, you must be transparent about fees and comply with FCA regulations. Failing to disclose true costs can lead to enforcement action.

7. Choosing the Right Legal Structure

Should you be a sole trader, partnership, or limited company? Your choice affects tax, liability, and compliance requirements. Many small firms incorporate as they grow, but advice from an accountant or solicitor is essential.

8. Drafting Bulletproof Terms & Conditions

T&Cs protect you against late payments, liability disputes, and intellectual property misuse. Templates can be useful, but for higher-risk businesses it’s worth investing in bespoke legal drafting.

9. Employment References – Do’s and Don’ts

If your business provides references, keep them factual. Overly positive or misleading references could expose you to legal claims. Likewise, refusing to provide references at all can harm employee relations.
