Simplified active substances
To encourage the use of products with a more favourable environmental or human or animal health profile, the GB Biocidal Products Regulation (GB BPR) establishes a list of active substances that are eligible for simplified product authorisation in Great Britain (GB).
The GB Simplified Active Substance List is intended to include substances identified as presenting a "low risk" and currently includes substances in the following categories:
- category A – equivalent to categories 1-5 of Annex I of the EU Biocidal Products Regulation (EU BPR) – includes substances such as food additives, weak acids and pheromones
- category B – equivalent to category 6 of Annex I of EU BPR – includes substances for which an active substance dossier has been validated in accordance with Article 7 (3) of GB BPR
- category C – equivalent to category 7 of Annex I of EU BPR – includes substances other than those in categories A and B
Applications can be made to HSE to include an active substance in category A or B of the GB Simplified Active Substance List. Products using simplified active substances may be eligible for the simplified authorisation procedure.
Active substances that may meet the criteria to be included on the GB Simplified Active Substance List (and that were not supported in the GB Review Programme) cannot be used in biocidal products / biocidal product families made available on the GB market until the active substance is formally included on the List and the biocidal product / biocidal product family is authorised.
Making available on the market means any supply of a biocidal product, whether in return for payment or free of charge, at all stages of the supply chain. Some examples of this could include:;
- manufacturer to distributor
- distributor to retail store
- retail store to user
Enforcement action may be taken where a simplified biocidal active substance that is not yet included on the List is made available on the GB market in a biocidal product / biocidal product family.
Check the criteria
Before considering supporting a simplified active substance for inclusion on the List in GB, you should check if it meets the criteria. To be considered for inclusion on the GB Simplified Active Substance List, there must be evidence that the substance does not give rise to concern.
An active substance is considered to give rise to concern where:
- it meets the criteria for classification according to GB Classification, Labelling and Packaging of Substances and Mixtures (GB CLP) Regulation as
- explosive / highly flammable
- an organic peroxide
- acutely toxic (category 1, 2 or 3)
- corrosive (category 1A, 1B or 1C)
- respiratory sensitising
- skin sensitising
- germ cell mutagenic (category 1 or 2)
- carcinogenic (category 1 or 2)
- toxic for reproduction (category 1 or 2 or with effects on or via lactation)
- toxic for specific target organs (single or repeated exposure)
- toxic to aquatic life (acute category 1)
- it fulfils any of the substitution criteria set out in Article 10 (1) of GB BPR:
- it meets the criteria for classification according to GB CLP as:
- carcinogenic (category 1A or B)
- mutagenic (category 1A or B)
- toxic for reproduction (category 1A or B)
- it meets the criteria to be considered to have endocrine disrupting properties
- it meets the criteria for being Persistent, Bio-accumulative and Toxic (PBT) or very Persistent and very Bio-accumulative (vPvB) according to UK REACH
- it meets the criteria for classification according to GB CLP as respiratory sensitising
- the acceptable daily intake / acute reference dose / acceptable operator exposure level is significantly lower that the majority of approved active substances for the same product type and use
- it meets two of the criteria for being PBT according to UK REACH
- there are concerns linked to the nature of the critical effects even with very restrictive risk mitigation measures
- it contains a significant proportion of non-active isomers or impurities
- it meets the criteria for classification according to GB CLP as:
- it has neurotoxic or immunotoxic properties
- a level of concern equivalent to that described in points 1 to 3 can be reasonably demonstrated based on reliable information

- Paper dossiers (or partial paper dossiers) must not be submitted.
- Dossiers should consist of three main sections:
- data in the form of study reports
- summaries of those data – either in IUCLID or word documents
- assessments of the hazard, exposures, risks and efficacy of the active substance in a representative product, including an overall summary – using this Risk Assessment Report (RAR) template
- All documents / attachments should be included within your IUCLID dossier
- Guidance on information requirements for active substances and biocidal products – applicants should use this document when preparing dossiers for active substance approval
- Biocides Submission Manual (BSM) series - describes how to build IUCLID dossiers with detailed and illustrative technical assistance
- Guidance and training on IUCLID is also available – please note that HSE is unable to provide support on IUCLID
Things to note
- HSE encourages pre-submission meetings with applicants to discuss:
- the simplified active substance dossier structure
- potential issues
- the basis of data waiving arguments – to reduce potential problems later in the process
- the proposed timescale for submission – to allow better work scheduling
- fees and likely timelines
What HSE will do
Applications for category A
After receiving your application HSE will:
- conduct a brief initial check of the information to confirm that it meets the requirements for the application type
- estimate how much it may cost ("initial estimated fee") to process the application based on the information provided
- issue an invoice to the applicant which must be paid within 30 days of the date of the invoice – failure to pay the requested fees will result in your application being rejected
- evaluate the application (once the initial estimated fee has been paid) to assess whether there is evidence that the substance does not give rise to concern – this will take approximately 180 days from the payment of the fees
- make a recommendation to the Secretary of State and Devolved Authorities as to whether the active substance can be included on the GB Simplified Active Substance List
- issue an invoice for a "top up" fee if the cost of evaluating the application has gone beyond the initial estimated fee, which must be paid within 30 days of the date of the invoice – failure to pay the requested fees will result in the substance's inclusion in the List being withheld
You may be asked to provide further information at various stages of the process. When such requests are made, the indicative timeframes given above will be suspended. Please note if the information you provide is not satisfactory, or you fail to provide the information within the specified deadline, your application may be rejected.
Applications for category B
After receiving your application HSE will:
- conduct a brief initial check of the information to confirm that it meets the requirements for the application type
- issue an invoice to the applicant for the validation fee which must be paid within 30 days of the date of the invoice – failure to pay the requested fees will result in your application being rejected
- conduct an initial assessment (validation) of the submitted information – this will take approximately 30 days from receiving the application and includes:
- determining if there are any significant data gaps – additional information may be requested
- estimating how much it may cost ("initial estimated fee") to evaluate the full application based on the information provided
- issue an invoice to the applicant for the initial estimated fee once the application has been validated
- evaluate the application to assess whether there is evidence that the substance does not give rise to concern – this will take approximately 365 days from validating the application
- make a recommendation to the Secretary of State and Devolved Authorities as to whether the active substance can be included on the GB Simplified Active Substance List
- issue an invoice for a "top up" fee if the cost of evaluating the application has gone beyond the initial estimated fee, which must be paid within 30 days of the date of the invoice – failure to pay the requested fees will result in the substance's inclusion in the List being withheld
You may be asked to provide further information at various stages of the process. When such requests are made, the indicative timeframes given above will be suspended. Please note if the information you provide is not satisfactory, or you fail to provide the information within the specified deadline, your application may be rejected.
Active substance inclusion / non-inclusion decision
When the evaluation of an application is completed, a decision will be made as to whether the active substance can be included on the GB Simplified Active Substance List. HSE will recommend that the active substance is not included on the List where:
it cannot be suitably demonstrated that the substance does not give rise to concern (ie it cannot be shown that the substance does not meet the criteria for concern given in Article 28 (2) of GB BPR)
Inclusion recommended
HSE will:
- send the applicant a copy of the draft conditions HSE intends to set for the active substance – these are set out in a draft Competent Authority Report (CAR)
- take into account the applicant's comments, where relevant
- recommend to the Secretary of State and Devolved Authorities that the active substance be included on the GB Simplified Active Substance List
- publish the Secretary of State's decision
- add the active substance onto the GB Simplified Active Substance List
You should:
- examine the draft Competent Authority Report (CAR) and return it to HSE (with comments if necessary) to indicate your agreement with the conditions
- wait until the inclusion decision has been published, and the active substance is included on the GB Simplified Active Substance List, and ensure you apply for and gain Product authorisation overview before making any products available on the market in GB
- ensure you comply with any deadlines associated with the inclusion, such as for any post inclusion data requirements or the substance may be removed from the List
- ensure you comply with general chemical and product safety law which continues to operate such as:
Inclusion not recommended
HSE will:
- send the applicant a copy of HSE's assessment and conclusions – these are set out in a draft Competent Authority Report (CAR)
