The good news is that you do not need a specific licence to sell most products on Amazon in the UK. But there are legal requirements you need to meet, and understanding the difference between business structures helps you start on the right footing.
The Short Answer
There is no "Amazon seller licence" in the UK. You can legally start selling on Amazon as a sole trader with minimal formal requirements. However, you do need to register as self-employed with HMRC if your trading income exceeds £1,000 per year, and you need to comply with general business regulations.
Sole Trader
Most new Amazon sellers start as sole traders. Registration is simple — you tell HMRC you are self-employed through their online portal. There is no cost to register, no formal paperwork beyond the HMRC registration, and you can start trading immediately.
As a sole trader, you and your business are legally the same entity. Your profits are taxed as personal income through Self Assessment. You are personally liable for any business debts or legal claims.
Limited Company
Registering a limited company through Companies House creates a separate legal entity. The company owns the business, and you are a director and shareholder. Registration costs £12–£50 and can be done online in a few hours.
The main advantages are limited liability (your personal assets are protected from business debts), potential tax efficiency at higher income levels (Corporation Tax may be lower than personal income tax), and a more professional business image.
The disadvantages are more administration (annual accounts, confirmation statements, Corporation Tax returns) and higher accountancy costs.
When to Switch from Sole Trader to Limited
Many sellers start as sole traders and switch to a limited company once their profits reach a level where the tax savings justify the additional administration — typically around £30,000–£40,000 in annual profit. Your accountant can advise on the optimal timing for your situation.
Category-Specific Licences
While there is no general Amazon seller licence, some product categories require specific approvals. Selling food products requires registration with your local council's Environmental Health department. Electrical products must meet safety regulations. Cosmetics must comply with UK cosmetics regulations. And some categories on Amazon require category approval (gating) through Seller Central.
Insurance
Amazon requires sellers with monthly sales above a certain threshold to carry product liability insurance. Even below that threshold, product liability insurance is a sensible precaution. Policies for small e-commerce businesses typically cost £100–£300 per year.
The barrier to entry for selling on Amazon in the UK is low — no special licence, minimal registration, and you can start as a sole trader. As your business grows, formalising your structure protects you and optimises your tax position.
