Barkwith Group

Barkwith Associates is a specialist regulatory affairs consultancy providing expert compliance services across the chemical, biocide, plant protection, and fertiliser sectors. Established in 2002, we operate from offices in Lincoln, England and Dublin, Ireland, serving clients throughout the United Kingdom and European Union markets. We deliver comprehensive regulatory support across seven core service areas: plant protection products (PPP), biocides (BPR), classification and labelling (CLP), fertilisers and biostimulants (FPR), biological assessment dossiers (BAD), biopesticides, and industrial chemicals including REACH compliance. Our plant protection products team provides full life-cycle support from active substance approval through product authorisation, including dossier preparation, risk assessment, efficacy evaluation, regulatory submissions, mutual recognition procedures, comparative assessment, substitution candidate evaluation, renewal applications, and post-authorisation change notifications. We support clients with regulatory strategy development and market access planning across EU and UK markets. For biocides, we offer expertise in active substance approval, product authorisation under the Biocidal Products Regulation, product family development and notifications, Article 95 list applications, treated article compliance, technical equivalence assessments, active substance and product authorisation renewals, and regulatory change management. Our Biocides team works across all 22 product types, supporting clients with Union authorisation procedures, mutual recognition, simplified authorisation routes, and regulatory strategy for both legacy active substances and new market entrants. Our classification and labelling services cover CLP regulation compliance, SDS authoring and updating, hazard classification and assessment, labelling review and optimisation, poison centre notifications including UFI generation and PCN submissions, CLP inventory notifications, harmonised classification dossier preparation, and ongoing regulatory monitoring to ensure continued compliance with evolving classification criteria. We support clients with self-classification processes, classification justification documentation, and preparation for regulatory authority queries. In fertiliser and biostimulants, we provide regulatory support under the Fertilising Products Regulation, including product compliance assessment, component material category evaluation, labelling and claims substantiation, conformity assessment body liaison, technical documentation preparation, CE marking compliance, and market surveillance response. We advise on the transition from national fertiliser schemes to EU FPR, supporting manufacturers with product reformulation strategies and authorisation pathways. Our biological assessment dossier services support the preparation and submission of ecotoxicological and environmental fate studies, toxicological assessments, exposure modelling, risk characterisation, endpoint study reports, read-across justifications, and QSAR analysis. We provide expert review of study reports, prepare robust study summaries and endpoint summaries, and support clients in regulatory authority discussions regarding data requirements and waiving strategies. For biopesticides and biological active substances, we deliver specialised regulatory support recognising the unique characteristics of microbial and biochemical plant protection products and biocides. Our services include development of biological dossiers, efficacy demonstration for biological modes of action, environmental fate assessment for biologicals, regulatory pathway selection, and liaison with evaluating authorities to ensure appropriate assessment frameworks are applied. Our industrial chemicals practice provides REACH compliance services including registration dossier preparation and updating, chemical safety assessment and chemical safety report authoring, exposure scenario development, substance evaluation support, restriction and authorisation dossier preparation, downstream user obligations, only representative services for non-EU manufacturers, consortium management and data sharing negotiation, and ongoing compliance monitoring. We support clients across the full REACH life-cycle from pre-registration through substance evaluation and restriction processes. We also provide classification and labelling support under REACH, SDS compilation for complex substance and mixture portfolios, regulatory horizon scanning to identify upcoming legislative changes, training and capacity building for in-house regulatory teams, and strategic regulatory consulting to optimise product portfolios and market access strategies. Our team of regulatory professionals brings deep technical expertise across chemistry, toxicology, ecotoxicology, environmental science, and regulatory affairs. We combine scientific rigour with practical commercial understanding, delivering regulatory solutions that enable market access while managing costs and timelines effectively. We work with chemical manufacturers, formulators, importers, distributors, only representatives, industry associations, and legal firms requiring specialist regulatory expertise. Our client base spans agricultural chemicals, industrial chemicals, biocides, detergents, cosmetic preservatives, construction chemicals, water treatment products, wood preservatives, antimicrobials, rodenticides, insecticides, disinfectants, fertilisers, soil improvers, growing media, and speciality chemical applications across multiple industrial sectors.

We also support UK regulatory frameworks including UK REACH, UK BPR, UK PPP regulations, GB CLP, and Great Britain and Northern Ireland regulatory requirements. We provide regulatory support across product life-cycles from initial market entry strategy through active substance approval, product authorisation, post-authorisation maintenance, regulatory change management, renewal applications, and product portfolio optimisation. Our services are designed to be flexible, supporting clients with full outsourced regulatory management or targeted project-based support depending on organisational needs and internal capabilities. Our dossier preparation services meet regulatory authority standards, with rigorous quality control processes ensuring submission-ready documentation. We prepare applications in required formats and manage the full submission process including competent authority liaison and response to regulatory questions. We support clients with regulatory strategy development, advising on optimal authorisation routes, data protection strategies, timing of market entry, competitive positioning relative to substitution and comparative assessment criteria, and long-term regulatory sustainability of product portfolios. Our commercial awareness ensures regulatory advice is delivered in the context of business objectives and market realities. For multinational clients, we coordinate regulatory activities across multiple European markets, managing zonal applications, mutual recognition procedures, parallel applications in multiple member states, and ensuring consistency in regulatory messaging and data interpretation across territories. We work effectively with local representatives, distributors, and legal entities to deliver coordinated pan-European regulatory programs. Our technical capabilities include human health risk assessment, ecological risk assessment, environmental fate modelling, occupational and consumer exposure assessment, and preparation of comprehensive risk characterisation documentation. We maintain extensive regulatory intelligence resources, tracking legislative developments, competent authority guidance updates, regulatory authority opinions, Commission decisions, court rulings affecting chemical regulation, and industry consultation processes. This intelligence informs our client advice and enables proactive regulatory planning. Our quality management processes ensure accuracy, consistency, and regulatory compliance across all deliverables. We maintain comprehensive audit trails, version control, peer review processes, and quality checking procedures to deliver regulatory submissions that withstand competent authority scrutiny. We support clients in regulatory authority interactions, including preparation for and attendance at competent authority meetings, response to requests for further information, defence of data waiving proposals, negotiation of testing strategies, and management of regulatory challenges or objections. For active substance approvals, we provide gap analysis of existing data against regulatory requirements, study monitoring, endpoint study report review, assessment report preparation, response to peer review processes, and strategic advice on data generation and submission timing.
