Legal & Compliance
You don't need to know all the rules. You need to know which ones apply to you.
Running a business comes with rules and responsibilities. The challenge isn't knowing every law — it's understanding which ones matter to your business.
- What do I need to have in place?
- Which rules apply to my business?
- What changes if I employ somebody?
- What am I forgetting?
The essentials
The 10 Legal & Compliance Non-Negotiables
Ten principles every small-business owner should understand. Not a legal checklist — a practical foundation.
Know which rules apply to your business
Legal obligations depend on what you do, how you're structured, whether you employ people, whether you sell to consumers, and whether your sector is regulated. The first step is understanding which rules are actually relevant to you — not trying to comply with everything.
Business Structure SelectorRegister your business correctly — and keep it current
Whether you're a sole trader registering with HMRC or a limited company filing with Companies House, registration is a legal requirement. Keeping your registration accurate — including notifying changes — is an ongoing obligation, not a one-off task.
Registering With HMRCUnderstand what your business structure actually means
Sole trader, limited company, partnership — the structure you choose determines your personal liability, your tax obligations, your filing requirements and what happens if things go wrong. Many founders choose a structure without fully understanding what it commits them to.
Choosing A Business StructureHandle personal data properly — and know your ICO obligations
If you collect, store or use any information about identifiable people — customers, employees, website visitors — UK GDPR applies to you. This includes having a privacy policy and understanding your lawful basis for processing. Depending on how you use personal data, you may also need to register with the ICO. This is not only for large organisations.
GDPR for Small Businesses
Put important agreements in writing
A verbal agreement is difficult to enforce and easy to misremember. Whether it's a contract with a client, terms of service for your website, or an employment agreement, written agreements protect both parties and reduce the risk of expensive disputes.
Creating Employment ContractsGet the insurance your business actually needs
Some insurance is legally required. Some is effectively required by clients or contracts. Some protects you from risks that could otherwise end your business. Understanding what you need — and what you don't — is a practical necessity, not a bureaucratic exercise.
Business Insurance GuideUnderstand what your customers are entitled to
Customers have legal rights — to refunds, repairs, replacements, and accurate information about what they're buying. These rights exist whether or not you've written them into your terms. Understanding them prevents disputes and protects your reputation.
Know your legal obligations before you employ anyone
Taking on an employee — even one part-time person — creates a set of legal obligations that many first-time employers don't anticipate: right-to-work checks, a written employment statement from day one, PAYE registration, auto-enrolment, and Employers' Liability insurance.
Hiring Your First EmployeeKeep proper records
Businesses are required to keep certain financial, company and employment records for specified periods. Good record-keeping isn't just good practice — in many cases, it's a legal requirement.
Know when professional advice is worth paying for
Business Handbook provides general guidance, not personalised legal advice. Some situations — a significant contract, a dispute, a regulatory question, a business sale — genuinely require a solicitor or specialist. Knowing when to get professional advice is itself a form of good judgement.
Worth knowing
The things you didn't realise were legal requirements
Most of these catch people out not because they're obscure, but because nobody told them.
If you process personal data
If your business holds personal data about customers, employees or website visitors, you are likely required to register with the ICO and pay an annual fee.
Most businesses. Not all. Check at ico.org.uk.
If you employ people
If you employ people, you may be legally required to have Employers' Liability insurance.
Check whether the requirement applies to your business.
If you employ people
Every employee and worker must receive a written statement of their employment terms on or before their first day. Not within a week. Day one.
On or before day one.
If you employ people
Before an employee starts working for you, you must check that they have the right to work in the UK and keep a record of that check. Checks can be done using original documents, online via the Home Office, or through an employer-checking service. The check must be completed before employment begins.
Before they start. Not after.
If you have a website
If your website collects any personal data — including through a contact form, a newsletter sign-up, or analytics — you are legally required to have a privacy policy that explains what you collect and why.
If you have a contact form, you need one.

A note on this guidance
Business Handbook provides general business information and practical guidance. It is not a law firm and does not provide personalised legal advice. Guidance reflects our understanding of UK law and practice at the time of writing. For advice specific to your circumstances, a solicitor or specialist adviser may be appropriate.
Sort the important stuff.
Then get back to the business.
The rules exist in the background of every business. Understanding which ones apply to yours — and having the right things in place — means you can focus on the part that actually matters: building something worth building.
