Biocide Regulations and Pest Control: UK Biocidal Products Regulation, Professional Use Products and Record-Keeping

Summary

The UK biocide regulatory framework underwent significant change following Brexit. Retained EU law — primarily EU Biocidal Products Regulation 528/2012 — became UK BPR, now administered domestically by the Health and Safety Executive (HSE). The practical effect for pest controllers is that product authorisations, active substance approvals, and labelling requirements continue largely as before, but with the HSE as the national competent authority rather than ECHA (European Chemicals Agency).

For everyday pest control operatives, the most important distinction is between general-sale products (available to the public) and "restricted use" or "professional use" products. Rodenticides containing second-generation anticoagulant rodenticides (SGARs) such as brodifacoum, bromadiolone, difenacoum and flocoumafen are the prime example: these are available only to trained professionals holding a recognised certification, and their use is further governed by the Campaign for Responsible Rodenticide Use (CRRU) UK Code of Best Practice. Misuse or improper disposal of these products carries serious legal consequences under both the Health and Safety at Work etc. Act 1974 and the Wildlife and Countryside Act 1981.

Record-keeping obligations are often underestimated. COSHH requires employers to maintain COSHH assessments for every substance used. For pest controllers operating commercially, this extends to site-specific risk assessments, product application logs, and proof of competency. These records are not merely bureaucratic box-ticking — they are the primary defence in any enforcement action by the HSE, local authority Environmental Health Officer (EHO), or in civil litigation following an incident involving non-target species, contamination, or human exposure.

Key Facts

• UK BPR — The domestic retained version of EU BPR 528/2012; administered by HSE post-Brexit. Governs product authorisation, active substance approval, and labelling
• Product Types under UK BPR — PT14 (rodenticides), PT18 (insecticides), PT19 (repellents), PT08 (wood preservatives with pest relevance) are the main pest control product types
• Restricted Use Products — May only be applied by, or under direct supervision of, a trained professional. Label states "For professional use only"
• CRRU Code of Best Practice — Voluntary but widely enforceable by contract; covers SGAR use in urban and agricultural settings; updated 2016 and 2021
• COSHH Regulations 2002 — Require employers to assess risks from hazardous substances, implement controls, and maintain records
• BASIS Prompt — Industry benchmark qualification for pest management professionals; covers legislation, biology, and safe use
• RSPH Level 2 Award — Entry-level professional qualification; minimum standard for most commercial pest control contracts
• BPCA membership — British Pest Control Association; members commit to CRRU and professional standards
• HSE product database — All authorised biocidal products searchable at hse.gov.uk; check before purchase or use
• Label is law — The product label constitutes legally binding conditions of use. Off-label use is illegal under UK BPR
• Record retention — COSHH records must be kept for at least 2 years; where biological monitoring is involved, 40 years
• SDS (Safety Data Sheet) — Must be obtained and reviewed before using any professional biocidal product; supplier must provide free of charge
• Secondary poisoning risk — SGARs accumulate in predators (owls, foxes, kestrels). CRRU bait points must be secured against non-target species
• Second-generation anticoagulants (SGARs) — Brodifacoum, bromadiolone, difenacoum, difethialone, flocoumafen — all "professional use only" in the UK
• First-generation anticoagulants (FGARs) — Chlorophacinone, coumatetralyl, diphacinone — some available to public, some professional only; check individual label
• Disposal obligations — Dead rodents from SGAR treatments must be collected and disposed of in accordance with the Environmental Protection Act 1990

Detailed Guidance

What UK BPR Means in Practice

The UK Biocidal Products Regulation (UK BPR) came into force on 1 January 2021 under the Biocidal Products (Regulation) (Amendment) (EU Exit) Regulations 2019. It retained the structure of EU BPR 528/2012 but created a parallel domestic authorisation system. Products authorised under EU BPR before the transition period ended continue to be recognised under Transitional Authorisations (TAs), but these are time-limited — they must be replaced by full UK BPR authorisations.

For pest controllers, the practical implication is: always verify that the product you intend to use holds a current UK BPR authorisation. The HSE publishes the UK Register of Biocidal Products. Using a product whose authorisation has lapsed is illegal, regardless of whether you personally knew the authorisation had expired.

Where a product is authorised in Great Britain (England, Scotland, Wales) but not Northern Ireland (which follows different arrangements under the Windsor Framework), this is clearly marked. Pest controllers operating across the border must check which authorisations apply.

Professional Competency Requirements

There is no single mandatory national licence to work as a pest controller in the UK, but several factors create de facto qualification requirements:

Contracts with public bodies (local authorities, NHS, food businesses) routinely specify RSPH Level 2 minimum or BPCA membership. Insurance underwriters frequently require proof of competency, and an unqualified operator who causes harm will find their liability exposure substantially greater.

For SGAR use specifically, the CRRU UK Code of Best Practice (2021 revision) effectively mandates that only trained professionals use these products in urban environments. "Trained" means holding an appropriate qualification — BASIS Prompt, RSPH Level 2, or equivalent. Operatives should keep certificates current; BASIS Prompt is a points-based CPD system requiring renewal.

Fumigation with aluminium phosphide is the most heavily controlled activity: operators require additional competency documentation, and applications in occupied buildings require HSE notification under COSHH regulation 16. Methyl bromide is effectively banned for most uses under the Montreal Protocol and can only be used for specific quarantine and pre-shipment treatments.

COSHH Compliance for Pest Controllers

COSHH 2002 creates a hierarchy of controls: eliminate the hazard, substitute with something less hazardous, apply engineering controls, administrative controls, and as a last resort, personal protective equipment (PPE). Pest controllers must document this hierarchy in their COSHH assessments for each substance.

A compliant COSHH file for a commercial pest controller should contain:

1. Inventory of all biocidal products used
2. Safety Data Sheets (current version — SDSs are revised when new hazard information emerges)
3. Substance-specific risk assessments for each product
4. Records of operator training and competency
5. Health surveillance records where relevant (e.g., for organophosphate exposure)
6. PPE inspection and maintenance records

COSHH assessments must be reviewed whenever the product, process, or workforce changes — not just annually.

Record-Keeping for Each Application

For every professional pest control visit, best practice — and often contractual requirement — is to record:

• Date and time of application
• Address and precise location of treatment
• Pest species being controlled
• Product name, UK BPR authorisation number, batch number
• Amount used (in grams or litres)
• Method of application (bait station, spray, dust, etc.)
• Operator name and qualification
• Any non-target species observed
• Client signature (for domestic contracts)

For rodenticide programmes, the CRRU Code additionally requires bait station maps, with GPS coordinates recommended for larger sites. Records must be available to show HSE inspectors or EHOs on request.

Reporting Incidents and Adverse Events

If a biocidal product causes unintended harm — poisoning of a non-target animal, human exposure, environmental contamination — this must be reported. Routes include:

• HSE — for worker or public exposure incidents (RIDDOR where relevant)
• Environment Agency / Natural Resources Wales / SEPA — for environmental contamination
• WIIS (Wildlife Incident Investigation Scheme) — for suspected secondary poisoning of wildlife; operated by HSE and Natural England
• NPIS (National Poisons Information Service) — for human poisoning; telephone 0344 892 0111

Prompt reporting is not just a legal obligation — it demonstrates responsible practice and is a significant mitigating factor in any subsequent enforcement action.

Frequently Asked Questions

Do I need a licence to buy SGAR rodenticides?

There is no formal HSE licence for purchasing SGARs in the UK, but retailers are only supposed to sell professional-use products to trained operators. In practice, some retailers check for proof of qualification; others do not. Regardless of how you obtained the product, using it without appropriate training is illegal under UK BPR and may attract HSE enforcement. The CRRU Code of Best Practice makes training a condition of responsible use.

What happens if I use a product off-label?

Using a biocidal product in a manner inconsistent with its authorised label is a criminal offence under the UK BPR. This includes using a higher dose than specified, applying to a surface not listed, or using in a location the label prohibits (e.g., near water courses). HSE can issue improvement notices, prohibition notices, or prosecute. Off-label use also invalidates your professional indemnity insurance.

How long must I keep application records?

COSHH requires records to be kept for at least 2 years. However, for contract pest control businesses, many commercial and public sector clients require records to be held for the duration of the contract plus 3–5 years. Records relating to potential long-term health exposure (e.g., fumigants) should be kept for 40 years under COSHH regulation 11(3).

Can I use general-sale insecticides professionally without any records?

Legally, COSHH applies to any substance that presents a health hazard, including general-sale products. You still need a COSHH assessment and should keep application records as a matter of good practice. If a client or their insurer queries the treatment, a record is your only evidence.

What is the CRRU Code and is it legally binding?

The Campaign for Responsible Rodenticide Use (CRRU) UK Code of Best Practice is a voluntary industry code, not primary legislation. However, it is written into many commercial pest control contracts, local authority tender requirements, and insurance policies. Breach of the Code in connection with environmental harm could also be used as evidence of negligence in civil proceedings.
