REGULATORY COMPLIANCE
HSE Biocides Regulation in Great Britain
Overview
Understanding GB Biocides Compliance
In Great Britain, biocidal products are regulated under the GB Biocidal Products Regulation (GB BPR), with the Health and Safety Executive (HSE) as the competent authority. This page explains what regulatory compliance actually means, what different terms signify, and how the system works for professional mould removal products.
Product Authorisation
Legal permission to supply a biocidal product for specific uses in GB market
Article 95 List
Supply-chain requirement ensuring active substance sources are compliant for market access
Product Type (PT)
Classification determining regulatory requirements and assessed uses (mould products typically PT2)
THE REGULATORY FRAMEWORK
How GB Biocides Compliance Works: Step by Step
- 01
Step 1: Product Classification & Product Type
First, HSE determines whether your product is regulated as a biocidal product and which Product Type (PT) it falls under. Biocides are grouped into 22 product types across 4 main groups.
Product Type 2 (PT2): Disinfectants & Algaecides
For mould removal on indoor hard surfaces (walls, ceilings, bathrooms), products typically fall under PT2: "Disinfectants and algaecides not intended for direct application to humans or animals". This covers disinfectants used in private, public, industrial, and other areas for the disinfection of surfaces.
hse.gov.ukHSE: Product types and groupsWhy this matters: The PT determines what evidence is needed for authorisation (efficacy standards, exposure scenarios, labelling requirements, user categories).
- 02
Step 2: Active Substance Status
The active substance (the chemical that provides the biocidal action) must have an appropriate regulatory status for the relevant PT + market (GB or NI). HSE maintains active substance lists showing approval status, review status, and expiry dates.
For each active substance, HSE tracks:
- Approved product types for that active
- Whether it's under review, approved, or subject to transitional arrangements
- Expiry dates for approvals
- Whether it's supported for GB, NI, or both
- 03
Step 3: Article 95 Compliance (Supply Chain Gate)
Article 95 is a supply-chain eligibility requirement. In GB, if the relevant active substance source (for the relevant product type) is not on the GB Article 95 List, then biocidal products containing that active cannot be made available on the GB market.
What Article 95 IS:
- A supply-chain gate ensuring someone in the chain has dossier access/rights for the active substance
- Confirmation that the active substance supplier is compliant for that PT + market combination
- A requirement HSE can enforce (non-compliance may result in enforcement action)
What Article 95 is NOT:
- Not product authorisation or approval
- Not validation of your efficacy claims
- Not a marketing badge showing "HSE approved product"
- Not confirmation that your finished product is safe for any specific use
- 04
Step 4: Product Authorisation (The Key Step)
To place a biocidal product on the GB market, you need the correct authorisation route under GB BPR. This is where the actual product, its formulation, uses, claims, and safety profile are assessed and approved.
Product authorisation controls:
- Exact formulation/specification including tolerances and impurities
- Approved uses: PT, use areas, application methods, user category (professional/general public)
- Approved claims + directions: which organisms, which surfaces, contact times, soil load conditions
- Risk mitigation: PPE requirements, ventilation, re-entry times, occupancy conditions, disposal
- Classification & labelling: hazard statements, safety phrases, child-resistant closures
- Change control: many changes require formal variation or notification to HSE
Critical Point for "Safe for Occupied Properties" Claims:
Claims like "safe for occupied indoor spaces" or "no tenant evacuation required" are only defensible if your product authorisation and label conditions actually support that scenario. The risk assessment must have evaluated resident exposure, ventilation requirements, and re-entry times that match your marketing claims.
- 05
Step 5: COPR (Legacy/Transitional Route)
HSE still runs COPR (Control of Pesticides Regulations) for certain product categories during the transition to full GB BPR. Some products hold COPR approvals which function similarly to authorisations for specified uses.
HSE publishes detailed COPR approved product lists showing:
- Product name and HSE approval number
- Expiry dates
- User category (professional/amateur)
- Target organisms
- Use areas
- Formulation type
- Risk mitigation measures required
Due diligence
How Procurement Teams Verify Compliance
When evaluating supplier claims about "HSE approved" or "regulatory compliant" biocidal products, procurement and health & safety professionals should verify against official HSE sources:
1. Check UK Authorised Biocidal Products List
HSE publishes comprehensive lists of biocidal products authorised under GB BPR and NI BPR. This is the primary verification source for product authorisation claims.
hse.gov.ukHSE: UK authorised biocidal products2. Verify Article 95 Listing
Check that the active substance source is listed on the GB Article 95 List for the relevant product type. This confirms supply-chain compliance but remember: Article 95 listing alone does NOT mean the product is approved.
hse.gov.ukThe GB Article 95 List3. Request Product Authorisation Details
Ask suppliers for their GB BPR authorisation number or COPR approval reference, and verify that:
- The authorised user category matches your intended use (professional vs general public)
- The approved use areas cover your application (residential housing, healthcare facilities, etc.)
- The efficacy claims match your needs (target organisms, contact times, surface types)
- Any PPE, ventilation, or occupancy restrictions are acceptable for your operations
4. Review Safety Data Sheet (SDS)
Request the current SDS and confirm that classification, handling requirements, and disposal instructions align with the supplier's safety claims. If a product is marketed as "non-hazardous" or "COSHH-free", the SDS should support this.
Two regimes
Great Britain vs Northern Ireland: Different Regimes
Since Brexit, biocides regulation in the UK has diverged:
Great Britain (England, Scotland, Wales)
- Regulated under GB BPR
- HSE is the competent authority
- GB Article 95 List applies
- Separate authorisation route from EU/NI
Northern Ireland
- Generally aligned to EU BPR
- ECHA systems and EU Article 95 apply
- Different authorisation requirements
- Must be considered separately for UK-wide supply
Understanding UK-wide Market Access:
Products marketed as "UK-wide approved" require appropriate authorisations for both GB and NI, as these are separate regulatory regimes with different requirements, lists, and competent authorities. When evaluating product compliance, procurement teams should verify which markets (GB, NI, or both) the product is authorised for.
TECHNICAL REQUIREMENTS
What Goes Into a Product Authorisation Dossier
Product authorisation under GB BPR requires comprehensive technical documentation demonstrating safety and efficacy. Understanding what regulators assess helps buyers evaluate supplier claims and identify potential gaps in compliance.
1. Product Identity & Composition
The authorisation ties the product to a specific formulation with defined tolerances:
- Active substance(s): Identity, concentration, purity specifications, and impurity profiles
- Co-formulants: All other ingredients including stabilisers, surfactants, buffers, preservatives
- Manufacturing process: How the product is made, quality control procedures, batch-to-batch consistency measures
- Physical-chemical properties: pH, density, viscosity, stability over shelf life, storage conditions
Why this matters for buyers: If a supplier makes formulation changes (even seemingly minor ones like switching raw material suppliers or adjusting stabiliser concentrations), they may need regulatory approval for the change. Ask suppliers about their change control process and whether recent modifications required HSE notification.
2. Efficacy Assessment
Efficacy claims must be supported by appropriate testing demonstrating the product works as claimed:
- Target organisms: Which specific fungi, bacteria, or other microorganisms the product is approved to remove (you can't just claim "all mould")
- Test standards: Evidence following recognised protocols (e.g, BS EN 1650 for disinfectants, EN 13697 for surface disinfectants)
- Contact times: How long the product must remain on the surface to achieve claimed efficacy (critical for "10 minute contact time" type claims)
- Application conditions: Temperature, soil load conditions, surface types where efficacy has been demonstrated
- Use concentration: The approved dilution or ready-to-use concentration that delivers the claimed performance
Red flags for buyers: Vague claims like "kills 99.9% of bacteria and viruses" without specifying which organisms, test standards, or contact times. Legitimate products have specific efficacy data tied to their authorisation. Ask suppliers for copies of efficacy summaries or test reports.
3. Human Health Risk Assessment
Probably the most critical section for "safe for occupied spaces" claims. The risk assessment evaluates:
- Exposure scenarios: Professional use vs general public; indoor vs outdoor; spray application vs wipe; occupied vs unoccupied spaces
- Exposure routes: Inhalation (most critical for sprays), dermal contact, accidental ingestion, eye contact
- Vulnerable populations: Children, pregnant women, elderly, occupational exposure for workers
- Risk mitigation measures: PPE requirements (gloves, masks, goggles), ventilation needs, re-entry times after application
- Classification & labelling: Hazard statements, precautionary statements, signal words (Danger/Warning), pictograms
Critical for Social Housing & Healthcare:
Products marketed as "safe for occupied properties" or "no evacuation required" must have risk assessments that specifically evaluated resident exposure scenarios during and after treatment. If the authorised label says "use only in unoccupied, well-ventilated areas" or "do not allow re-entry for X hours", then marketing claims about occupied-space safety are not aligned with the regulatory approval. Always request the approved label and safety data sheet to verify.
4. Environmental Fate & Effects
Environmental assessment evaluates what happens to the product after use:
- Degradation: How quickly the product breaks down in water, soil, or air; what breakdown products form
- Aquatic toxicity: Effects on fish, invertebrates, algae (relevant when product rinses down drains)
- Bioaccumulation: Whether substances accumulate in organisms or food chains
- Waste disposal: Requirements for disposal of unused product, empty containers, application residues
5. Labelling & Instructions for Use
The approved label is legally binding and must include:
- Authorisation number: The GB BPR or COPR reference that buyers can verify on HSE lists
- Approved uses: Exactly what surfaces, areas, and organisms the product can be used against
- Directions for use: Application method, dilution (if applicable), contact time, surface preparation
- Safety information: Hazard statements, precautionary statements, first aid, safe disposal
- Storage conditions: Temperature limits, shelf life, container requirements
Verification Tip:
Request a copy of the approved product label and compare it against marketing materials. All claims in advertising must be supported by the authorised uses and not contradict any label restrictions or warnings. If marketing says "no PPE required" but the label mandates gloves and eye protection, that's non-compliance.
Myths vs reality
Common Misunderstandings About Biocides Regulation
Misunderstanding: "Article 95 listing means the product is HSE approved"
Reality: Article 95 is purely a supply-chain compliance mechanism. It confirms that someone in the supply chain has dossier rights for the active substance + product type combination, allowing products containing that active to be marketed. It does NOT mean:
- Your specific finished product has been evaluated or approved by HSE
- Your efficacy claims have been validated
- Your safety claims are correct
- Your product meets any particular standards
What to do: Always ask for the actual product authorisation number, not just Article 95 status.
Misunderstanding: "If the active substance is approved, our product is approved"
Reality: Active substance approval (inclusion on the positive list for a PT) is only one step. Each individual biocidal product containing that active still requires its own authorisation covering:
- The specific formulation (including all co-formulants and their interactions)
- The specific uses and application methods
- Product-specific risk assessment based on actual exposure scenarios
- Product-specific efficacy data at the use concentration
Different products with the same active substance can have completely different authorisations, approved uses, and safety requirements.
Misunderstanding: "COSHH-free means no regulation applies"
Reality: "COSHH-free" typically means the product is not classified as hazardous under CLP (Classification, Labelling and Packaging) regulations, which reduces COSHH assessment burden but doesn't eliminate it. More importantly:
- The product still requires biocides authorisation
- Employers still have general health & safety duties
- Instructions for use must still be followed
- "Non-classified" doesn't automatically mean "safe for all applications"
Best practice: Even for non-classified products, maintain records of use, train staff on proper application, and follow manufacturer instructions.
Misunderstanding: "Testing to a standard (e.g, BS EN 1650) equals regulatory approval"
Reality: Test standards like BS EN 1650, EN 13697, EN 14476 are methods for generating efficacy data, not approval schemes. You can have:
- Products tested to these standards that are not authorised
- Test results that don't meet pass criteria
- Tests conducted under conditions that don't match real-world use
What to verify: Ask whether the test results were submitted as part of an authorisation dossier and accepted by HSE, not just whether testing was done.
Misunderstanding: "Natural ingredients mean no regulation/no hazard"
Reality: Regulatory requirements apply equally to biocides made from natural or synthetic sources. Many natural substances can be hazardous (e.g, plant extracts, essential oils, naturally-derived acids). The biocides framework regulates based on function (biocidal activity), not origin. A product made from "just water, salt, and electricity" still requires:
- Product Type classification
- Active substance approval status
- Article 95 compliance
- Product authorisation with risk assessment
- Approved label and safety data sheet
COSHH
Understanding "COSHH-free" in Context
"COSHH-free" is a common marketing term in the biocides sector, particularly for mould removal products targeting social housing and healthcare. Here's what it actually means and what it doesn't mean.
What is COSHH?
COSHH (Control of Substances Hazardous to Health) is UK workplace health and safety legislation requiring employers to prevent or reduce workers' exposure to substances hazardous to health. COSHH applies to substances classified as hazardous under CLP regulations.
When a product is classified as hazardous (based on its toxicity, corrosivity, irritancy, etc.), employers must conduct COSHH risk assessments, implement control measures (PPE, ventilation, exposure monitoring), maintain health surveillance where needed, and keep records.
What "COSHH-free" usually means:
- Product is not classified as hazardous under CLP regulations
- No hazard pictograms, signal words, or H-statements on label
- Reduced or simplified risk assessment requirements
- Generally no mandatory PPE beyond basic hygiene practices
- Lower training burden for operational staff
- Simpler storage and handling procedures
What "COSHH-free" does NOT mean:
- Product doesn't require biocides authorisation
- No regulatory compliance is needed
- Product can be used outside authorised conditions
- No general workplace risk assessment required
- Instructions for use can be ignored
- Product is automatically safe for all applications
Best Practice for Procurement:
When evaluating "COSHH-free" products, request:
- The current Safety Data Sheet (SDS) - Section 2 will show classification status
- The product label - confirms no hazard classification
- The GB BPR authorisation number or COPR approval - confirms regulatory compliance
- Confirmation that intended use matches authorised uses
- Details of any use restrictions even for non-classified products (e.g, ventilation recommendations, application methods)
