Complete Legal Guide to Starting a Business in the UK

Essential legal considerations when setting up and running a business

14 min readLast updated: 6 January 2025

Choosing Your Business Structure

The legal structure you choose affects your personal liability, tax position, and administrative requirements. The main options in the UK are sole trader, partnership, limited liability partnership (LLP), and private limited company. Each has advantages and disadvantages.

As a sole trader, you and your business are legally the same entity. This is the simplest structure with minimal admin, but you're personally liable for business debts. Partnerships are similar but with two or more people sharing profits, losses, and liability. An LLP provides partnership flexibility with limited liability for partners.

A private limited company is a separate legal entity from its owners (shareholders). Directors run the company, and shareholders' liability is limited to their investment. This structure offers credibility and tax planning opportunities but requires more administration, including filing annual accounts and confirmation statements with Companies House.

Registering Your Business

The registration requirements depend on your chosen structure. Sole traders must register for self-assessment with HMRC and notify them within three months of starting to trade. You'll need to keep records and submit a tax return each year.

Limited companies must be registered with Companies House. You can do this online, and it typically takes 24 hours. You'll need to provide details of directors, shareholders, a registered office address, and articles of association (or adopt model articles). Annual accounts and a confirmation statement must be filed each year.

You may also need to register for VAT if your taxable turnover exceeds £90,000 (or voluntarily if below), obtain relevant licences or permits depending on your industry, register as an employer if you hire staff, and consider data protection registration with the ICO if you handle personal data.

Contracts and Terms of Business

Clear contracts are essential for protecting your business. You should have written terms of business that cover your products or services, pricing and payment terms, delivery, cancellation rights, liability limitations, and dispute resolution. Different terms may be needed for business customers (B2B) and consumers (B2C).

Consumer contracts must comply with the Consumer Rights Act 2015, which gives consumers certain rights that cannot be excluded, including the right to goods of satisfactory quality and services performed with reasonable care. B2B contracts allow more flexibility, but terms must still be fair and clearly communicated.

Employment contracts are required for all employees and must include certain particulars (terms) within two months of starting work. Consider also having confidentiality agreements, intellectual property assignments, and restrictive covenants where appropriate. Having a solicitor review key contracts can prevent costly disputes later.

Protecting Your Intellectual Property

Intellectual property (IP) can be one of your most valuable business assets. The main types are trade marks (brand names, logos), patents (inventions), copyright (creative works), and design rights (product appearance). Understanding what protection you have and what you might need to register is crucial.

Trade marks should be registered to protect your brand name and logo. Registration gives you exclusive rights to use the mark for the goods or services covered and the ability to take legal action against infringers. The process takes about four months if there are no objections.

Copyright arises automatically when you create original works, but keeping records of creation dates is wise. Patents require registration and protect new inventions for up to 20 years, but the process is complex and expensive. Design registration protects the appearance of products. Consider what IP is important to your business and take steps to protect it.

Employment Law Basics

Once you employ staff, you take on significant legal obligations. Employees have extensive rights from day one, including protection from discrimination, the right to minimum wage, working time protections, and the right to a written statement of terms. After building service, additional rights like unfair dismissal protection apply.

You must operate PAYE (Pay As You Earn) to deduct income tax and National Insurance from employees' wages and pay these to HMRC. You must also provide workplace pensions under auto-enrolment rules. Keep careful records of hours worked, pay, and leave entitlement.

Employment law is complex and the consequences of getting it wrong can be serious. Having proper contracts, policies (including disciplinary and grievance procedures), and following fair procedures when issues arise is essential. An employment solicitor can help you set up compliant systems from the start.
