Upcoming GB active substance renewal submission deadline

Apply for active substance renewal by the deadline to keep products on the GB market.

Under the GB Biocidal Products Regulation (GB BPR), active substance approvals will expire unless a renewal application is submitted to HSE at least 550 days before their expiry date.

The 550-day deadline is coming up for the following active substance/product type combinations under GB BPR:

27 August 2026

  • α-cyano-4-fluoro-3-phenoxybenzyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (cyfluthrin) (CAS 68359-37-5 EC 269-855-7) in product type 18
  • citric acid (CAS 77-92-9 EC 201-069-1) in product type 2


Any person, company or task force/consortium can support an active substance/product type combination for renewal – it doesn’t have to be the original supporter.

Check the GB Article 95 List to see who the original supporters were.

If any of these active substance/product type combinations are important to you, consider contacting your supplier to let them know.

If a renewal application is not submitted for the above active substance/product type combinations under GB BPR, the approvals will expire. This means the active substances will no longer be able to be used in biocidal products of the relevant product types in GB.

In addition articles treated with such products will no longer be able to be placed on the market in GB.


Upcoming GB active substance open invitation deadline

Submit a notification by the deadline to keep active substances in the GB Review Programme.

HSE has published an open invitation to provide an opportunity for a person, company or task force/consortium to notify an intention to take up or take over the role of participant in the GB Review Programme for the following active substance/product type combinations.

Anyone wishing to support one of the active substance/product type combinations listed in GB will need to submit a notification to HSE by the following deadline:

18 February 2027

  • Silver phosphoborate glass (CAS N/A EC N/A) in product types 2, 7 and 9


If a notification to take over the role of participant is not received, the active substance/product type combinations will be subject to a GB non-approval decision. This means the active substance will no longer be able to be used in biocidal products of the relevant product types in GB.

In addition articles treated with such products will no longer be able to be placed on the market in GB. HSE will provide separate updates on these where relevant.

If you are aware of any disproportionate negative impacts that are likely to arise from the non-approval of the active substance/product type combination listed, please contact us via email.


Upcoming GB active substance expiry date

Biocidal products must be phased off the GB market.

The active substance/product type combination listed is due to expire under the GB BPR on the following date:

28 February 2027

  • Bacillus thuringiensis subsp. kurstaki, strain ABTS-351 (CAS N/A EC N/A) in product type 18


Once the approval expires, the active substance will no longer be able to be used in biocidal products of the relevant product type in GB.

In addition articles treated with such products will no longer be able to be placed on the market in GB.

If you hold an affected GB BPR product authorisation or Control of Pesticides Regulations (COPR) product approval, we will contact you about cancelling or revoking your authorisation or approval. You will have an opportunity to submit comments or additional information and we will take account of these when finalising our decision.

If you are aware of any disproportionate negative impacts that are likely to arise from the expiry of the active substance/product type combination listed, please contact us via email.

New to the job: health and safety

Workers have the same chance of an accident in the first 6 months at a workplace as during the rest of their working lives.

Anyone new to the workplace will be facing unfamiliar risks from the job they will be doing and from their surroundings.

We have guidance to protect those new to a job, which includes an in-depth guide to these 6 steps to protect new workers.
