Making soap for personal use and selling soap to the public are very different things. Once money changes hands, soap making moves from a hobby into a regulated activity, and it’s essential to understand your legal responsibilities before selling even a single bar.
This guide outlines the key things every UK soap maker needs to know before selling soap legally.
1️⃣ Soap Is a Regulated Product
In the UK, most handmade soap is classed as a cosmetic product — even when it’s made using traditional methods and natural ingredients.
If your soap is:
- Used to cleanse the body, hands, or face
- Marketed with cosmetic claims (cleansing, moisturising, gentle, nourishing, etc.)
…it falls under UK cosmetic regulations and must meet specific legal requirements.
Natural ingredients, traditional methods, or small batch production do not exempt you from compliance.
2️⃣ You Must Have a Cosmetic Safety Assessment (CPSR)
Before you sell soap, each product must have a Cosmetic Product Safety Report (CPSR) completed by a qualified safety assessor.
A CPSR:
- Reviews your full formulation
- Assesses ingredient safety and usage levels
- Confirms the product is safe for consumer use
You cannot legally sell soap without a valid CPSR, even at:
- Craft fairs
- Markets
- Online
- To friends or family
3️⃣ You Must Notify the Product Before Sale
All cosmetic products sold in the UK must be notified on the UK cosmetic notification system before being placed on the market.
This process registers:
- The product
- The responsible person
- Ingredients
- Product category
This step is essential and must be completed before selling.
4️⃣ Correct Labelling Is a Legal Requirement
Soap labels must meet specific requirements. At minimum, labels must include:
- Product name
- Net weight at time of packaging
- Full INCI ingredients list (not common names)
- Name and address of the responsible person
- Batch or lot number
- Any required warnings (if applicable)
Incorrect or incomplete labelling is one of the most common compliance issues for new soap businesses.
5️⃣ You Must Keep a Product Information File (PIF)
A Product Information File (PIF) must be created and kept for each product.
This file contains:
- CPSR documentation
- Product formulation
- Manufacturing method
- Ingredient specifications
- Label artwork
- Batch records
PIFs must be kept up to date and available if requested by authorities such as Trading Standards or the Office for Product Safety and Standards.
6️⃣ Claims Matter More Than You Think
What you say about your soap matters legally.
You cannot make:
- Medical claims
- Healing or treatment claims
- Claims that suggest the product alters skin conditions
Even phrases used casually on websites, labels, or social media can affect how your product is classified.
When in doubt, keep claims:
- Factual
- Cosmetic-focused
- Non-medical
7️⃣ Insurance Is Essential
If you sell soap, you should have:
- Product liability insurance
- Public liability insurance (especially for markets)
Insurance protects you and your customers and is often required by:
- Market organisers
- Retail stockists
- Online platforms
8️⃣ “Small Business” Does Not Mean “Low Responsibility”
Many new soap makers assume rules only apply to large companies. This is not the case.
If you sell:
- One bar or one thousand bars
- Online or in person
- Part-time or full-time
…the same legal responsibilities apply.
Compliance isn’t about red tape — it’s about consumer safety, professionalism, and protecting your business.
9️⃣ Why Doing It Properly Matters
Selling soap legally:
- Builds trust with customers
- Protects you from fines or product recalls
- Makes future growth easier
- Positions your brand as professional and credible
Many successful soap brands — including Bold Natural Soap — started by learning these foundations early and building correctly from the beginning.
