BPR Compliant Disinfectant
A complete guide to the UK Biocidal Products Regulation — what it means for your disinfection programme, how to verify product compliance, and why BPR authorisation matters for duty holders, facilities managers, and water treatment professionals.
The Biocidal Products Regulation (BPR) is the legal framework governing the sale, supply, and use of biocidal products in Great Britain. Any disinfectant used to control harmful organisms — whether for water treatment, surface disinfection, food processing hygiene, or healthcare infection control — must hold valid BPR product authorisation for its intended use. Non-compliant products expose organisations to legal risk, invalidate insurance, and may compromise public health. This guide explains the BPR framework in practical terms, outlines the product type categories relevant to disinfection, and shows how to verify that the products you use are fully authorised.
What Is the Biocidal Products Regulation (BPR)?
The Biocidal Products Regulation — originally EU Regulation 528/2012 and retained in UK law as the GB BPR following Brexit — establishes the rules for placing biocidal products on the market in Great Britain. The regulation is administered by the Health and Safety Executive (HSE) in England, Scotland, and Wales, with separate arrangements in Northern Ireland under the EU BPR.
The BPR requires that all biocidal products are authorised before they can be sold, supplied, or used. Authorisation involves a rigorous assessment of the product's efficacy (does it work?), safety for human health and the environment, and physical and chemical properties. Only products that meet these standards receive a BPR product authorisation number.
The regulation covers 22 product types (PTs) grouped into four main areas: disinfectants (PT1–PT5), preservatives (PT6–PT13), pest control (PT14–PT20), and other biocidal products (PT21–PT22). For water treatment and disinfection professionals, the most relevant product types are PT2 (disinfectants for private and public health areas), PT4 (food and feed area disinfection), and PT5 (drinking water disinfection).
It is important to understand that BPR authorisation is product-specific and use-specific. A product authorised for surface disinfection (PT4) is not automatically authorised for drinking water treatment (PT5) or swimming pool disinfection (PT2). Duty holders must verify that the specific product they use carries authorisation for their specific intended application.
Understanding Product Types: PT2, PT4, and PT5
PT2 — Disinfectants and algaecides not intended for direct application to humans or animals — covers products used for disinfecting surfaces, equipment, and water in private and public health areas. This includes swimming pools, spas, hot tubs, cooling towers, air conditioning systems, and building water systems. PT2 is the most common authorisation required for water treatment disinfectants used in Legionella control, spa disinfection, and cooling water treatment.
PT4 — Food and feed area disinfection — covers products used for disinfecting equipment, containers, utensils, surfaces, and pipework associated with the production, transport, storage, or consumption of food, feed, or drink. This includes commercial kitchens, food processing plants, dairy facilities, breweries, and any environment where surfaces come into contact with food or beverages. PT4 authorisation requires demonstration of food-safe residues.
PT5 — Drinking water disinfection — covers products used for the disinfection of water intended for human consumption. This is the most stringently assessed product type, requiring proof of efficacy at the point of use and comprehensive toxicological assessment to ensure that treated water meets drinking water quality standards. PT5 products must not introduce contaminants or by-products that exceed Drinking Water Inspectorate (DWI) limits.
Other product types relevant to specific disinfection applications include PT11 (preservatives for liquid cooling and processing systems) and PT12 (slimicides — products used to prevent or control slime growth on materials, equipment, and structures used in industrial processes). Understanding which product type applies to your application is the first step toward ensuring compliance.
Why BPR Compliance Matters for Duty Holders
Under the Health and Safety at Work etc. Act 1974, the Management of Health and Safety at Work Regulations 1999, and specific regulations such as the Control of Substances Hazardous to Health Regulations 2002 (COSHH), duty holders have a legal obligation to ensure that any biocidal products used in their premises are suitable for purpose and compliant with applicable regulations.
Using a non-BPR-authorised disinfectant is a regulatory offence. The HSE can take enforcement action against organisations that sell, supply, or use unauthorised biocidal products. Penalties can include prohibition notices, improvement notices, and prosecution. In the event of a public health incident — such as a Legionella outbreak — the use of non-compliant products would be a significant aggravating factor in any investigation or legal proceedings.
Insurance implications are equally serious. Many professional indemnity and public liability policies require compliance with applicable regulations as a condition of cover. An organisation using an unauthorised biocidal product that subsequently causes harm may find their insurance claim denied. Water treatment contractors and service providers face particular exposure — their professional credibility depends on using and recommending only fully authorised products.
Beyond legal and financial risk, BPR compliance is a matter of public health. The authorisation process exists to ensure that disinfectants actually work at the concentrations and conditions claimed, and that they do not introduce unacceptable risks to users, bathers, building occupants, or the environment. Using authorised products means using products that have been independently assessed and verified.
How to Verify BPR Compliance
Every BPR-authorised product is assigned a unique product authorisation number. In Great Britain, this takes the format of a GB BPR number, while products authorised under the EU BPR (relevant in Northern Ireland) have an EU authorisation number. This number should be clearly displayed on the product label and in the product's Safety Data Sheet (SDS).
The HSE maintains the GB Biocidal Products Register, which is the official database of all authorised biocidal products in Great Britain. Duty holders and specifiers can search this register to verify that a product holds valid authorisation for the claimed product type. If a product does not appear on the register with the correct product type authorisation, it should not be used for that application.
When evaluating a disinfectant supplier, ask for the following documentation: the BPR product authorisation number, the current Safety Data Sheet (SDS), the Technical Data Sheet (TDS), and confirmation of the specific product types for which the product is authorised. Reputable suppliers will provide this information readily — reluctance to share regulatory documentation is a significant red flag.
It is also important to verify that the product authorisation covers your specific use case. A product authorised only for PT4 (food area disinfection) cannot legally be used for PT2 (water treatment in spas and pools) or PT5 (drinking water), even if the active substance is the same. The formulation, concentration, and conditions of use are assessed separately for each product type.
Common Compliance Pitfalls to Avoid
One of the most common compliance failures is using a product for an application outside its authorised product type. This often occurs when a general-purpose disinfectant is used in a drinking water system, or when a product authorised for surface cleaning is repurposed for water treatment. Even if the active substance is effective, the product itself must be authorised for the specific application.
Another frequent issue is relying on active substance approval rather than product authorisation. The BPR operates at two levels: active substance approval (confirming that a substance can be used in biocidal products) and product authorisation (confirming that a specific formulated product is safe and effective). Active substance approval alone does not permit sale or use — the formulated product must hold its own authorisation.
Transitional arrangements have created confusion in the market. Some products may be on the market under transitional provisions while their authorisation applications are being assessed. While these products can legally be sold during the transitional period, duty holders should understand the difference between a fully authorised product and one operating under transitional arrangements, and factor this into their procurement decisions.
Finally, some suppliers import products authorised in other jurisdictions and claim equivalence with GB BPR authorisation. Following Brexit, the GB BPR is a separate regulatory regime. Products must hold specific GB BPR authorisation — an EU authorisation alone is not sufficient for the Great Britain market (England, Scotland, and Wales).

How to Ensure Your Disinfection Programme Is BPR Compliant
A practical step-by-step guide to verifying and maintaining BPR compliance across your disinfection programme.
Identify All Biocidal Products in Use
Create a complete inventory of every disinfectant, biocide, and antimicrobial product used across your premises. Include water treatment chemicals, surface disinfectants, hand sanitisers, and any other products intended to destroy, deter, or render harmless any harmful organism. Record the product name, manufacturer, supplier, and claimed application.
Determine the Required Product Type for Each Application
For each product, identify the correct BPR product type based on its intended use. Swimming pool or spa disinfection requires PT2. Surface disinfection in food areas requires PT4. Drinking water treatment requires PT5. Cooling water treatment may require PT2 or PT11 depending on the system. Match each product to the correct product type.
Verify Product Authorisation on the HSE Register
Check each product against the HSE's GB Biocidal Products Register to confirm it holds valid authorisation for the required product type. Record the BPR authorisation number and verify it matches the number on the product label and Safety Data Sheet. Flag any products that cannot be verified.
Obtain Complete Regulatory Documentation
Request the current Safety Data Sheet (SDS), Technical Data Sheet (TDS), and BPR authorisation confirmation from each product supplier. File this documentation centrally and ensure it is accessible for regulatory inspections, COSHH assessments, and insurance audits. Replace any outdated SDS versions.
Replace Non-Compliant Products and Update Records
For any products that lack valid BPR authorisation for their intended use, identify compliant alternatives.

Expert Insights
"BPR compliance is not optional and it is not a box-ticking exercise — it is the foundation of a responsible disinfection programme. Every product we supply carries full authorisation for its intended product type, with complete documentation to back it up. If a supplier cannot provide you with a BPR authorisation number and current SDS, that should be an immediate disqualifier."
Gavin Owen
Managing Director, ChloroKlean
"We regularly encounter organisations using disinfection products that are not authorised for their specific application — a surface cleaner used in a water system, or a product authorised in the EU but not under the GB BPR. The regulatory risk is real, and in the event of an incident, non-compliance will be the first thing an investigator looks at."
Gavin Owen
Managing Director, ChloroKlean
"The BPR exists to protect public health. When you choose a fully authorised product, you know it has been independently assessed for efficacy and safety — not just by the manufacturer, but by the regulator. That assurance is worth everything when you are responsible for the water quality in a hospital, a hotel, or a public swimming pool."
