Understanding fire safety risks in Essex renewable energy sector: Essential strategies for compliance and protection in 2025
This guide explains what fire safety risks in Essex renewable energy sector look like, why they matter for site owners and managers, and the practical, compliant measures you should adopt in 2025 to protect people, assets and operations. You will learn how battery energy storage, EV charging, solar arrays and other renewable installations change fire risk profiles, what legal duties apply, and how to create a robust, evidence-based mitigation plan.
Why the renewable transition changes fire risk in Essex
Essex is seeing rapid growth in renewable infrastructure: rooftop and ground-mounted solar, commercial electric vehicle charging, solar-plus-storage and increasingly large battery energy storage systems. These installations are essential for net zero targets, but they introduce new fire hazards that differ from conventional fuel or electrical systems.
Battery chemistries can experience thermal runaway, and poorly installed or stored batteries increase the chance of rapid, hard-to-extinguish fires. Fire and Rescue Services and national bodies have highlighted a rise in battery-related incidents across the UK, making these hazards a priority for premises managers and developers. See nfcc.org.uk for reporting on battery incidents.
Key fire safety risks in Essex renewable energy sector
Battery energy storage systems present one of the most significant risks. Large-scale and modular battery installations contain many cells packed closely together. If one cell fails, heat can propagate quickly, creating a thermal event that may ignite adjacent cells and produce toxic gases. Relevant UK guidance for grid-scale storage highlights the need for specific health and safety planning for these systems. See gov.uk for technical guidance.
Electric vehicle charging and EV fleets create another area of risk. On-site charging rooms, poorly ventilated garages and communal residential charging points increase the presence of lithium-ion batteries in daily use and storage. GOV.UK guidance on e-cycle and e-scooter battery management demonstrates the practical fire-safety concerns linked to charging behaviour and storage locations. See gov.uk.
Solar arrays and inverter substations usually represent a lower fire frequency but carry significant fire spread and access issues. Roof-mounted arrays can complicate firefighting access and smoke management. Additionally, the interaction between renewable plant and existing oil or flammable material stores on industrial sites must be assessed. HSE and sector guidance on storage of flammable liquids remain applicable where biodiesel, lubricants or fuels are present. See hse.gov.uk for guidance on flammable liquid storage.
Hydrogen and biofuel projects are less widespread in Essex but are growing. Each fuel type brings specific storage and ventilation requirements. Early engagement with planners and fire authorities is essential to ensure safe siting, separation and mitigation.
Regulatory duties and enforcement: what Essex businesses must know
The Regulatory Reform (Fire Safety) Order 2005 places responsibility on the dutyholder to carry out a suitable and sufficient fire risk assessment and to implement measures proportionate to the risk. Failure to have an up-to-date assessment can result in enforcement action and significant safety consequences. Local Fire and Rescue Services continue to flag missing or inadequate assessments as a main compliance issue in 2025. See en.wikipedia.org for the Order reference.
In addition, specialist installations such as grid-scale storage must follow relevant technical standards and guidance from government departments and national committees. Planning consultees, building regulations and guidance from the National Fire Chiefs Council should inform mitigation and operational planning. The NFCC is updating its BESS guidance to reflect industry learning, and fire and rescue services increasingly expect operators to provide pre-plans and risk information. See nfcc.org.uk for consultation material.
Practical mitigation: design, installation and site management
Start with a site-specific fire risk assessment that recognises renewable-specific hazards. A competent assessor will identify ignition sources, evaluate battery management practices, and set out segregation, detection and suppression requirements. For help with this step, property managers often engage specialists. Total Safe’s fire risk assessment services can be used to develop a bespoke mitigation plan that aligns with British Standards and local expectations. Total Safe fire safety services.
Design controls should focus on separation, ventilation and thermal management. For battery systems, physical separation between battery strings, fire-resistant barriers, and clear access corridors allow early intervention and reduce likelihood of escalation. Consider remote monitoring for cell temperature and smoke detection within battery enclosures, and place firefighting-rated isolation switches for electrical isolation.
Suppression choices depend on the installation. Traditional water-based systems may be suitable for surrounding plant, but some battery fires require specialist suppression and remote extinguishing strategies. Operators should consult manufacturer guidance and pre-arrange response plans with the local Fire and Rescue Service.
Charging infrastructure must be installed to recognised standards, with dedicated circuits, appropriate RCDs and fixed charging points where possible. Avoid ad-hoc charging in escape routes or communal stairwells. Establish charging policies, clearly labelled charging bays and locking storage for user-owned batteries.
Operational controls and workforce readiness
Training, inspection and maintenance form the daily backbone of safety. Provide staff and contractors with training on charging protocols, safe battery handling and emergency shutdown. Regular tests of alarm systems, weekly fire alarm tests and periodic drills build familiarity and confidence.
A clear incident plan should identify the roles and responsibilities during a battery or electrical incident. That plan should include escalation to specialist manufacturers for technical support, and liaison contacts for local Fire and Rescue Services. Ensure that emergency plans are included in contract handovers for third-party operators and contractors.

Planning, consultation and community engagement
Developers and site operators should involve the local planning authority and, where appropriate, the Fire and Rescue Service at the earliest stages. NFCC guidance stresses collaboration to produce proportionate local risk management and operational plans for grid-scale BESS and similar projects. Early engagement reduces delays and ensures emergency response teams understand the layout and hazards before an incident occurs. See nfcc.org.uk.
Local community and waste-management risks must also be considered. Battery fires in waste streams have risen markedly and can affect surrounding areas through smoke and air pollution. Implementing recycling and disposal procedures on-site, and educating staff about safe disposal, can reduce the chance of off-site escalation. NFCC reporting highlights this as a national concern. See nfcc.org.uk.
Insurance, incident learning and continuous improvement
Insurers expect documented risk assessments, maintenance records and evidence of good practice. A single major incident can affect premiums or lead to policy exclusions. After any incident, conduct a formal review, record findings and update the risk assessment and operational procedures. Share lessons with the workforce and, as appropriate, with local responders.
Industry guidance and government publications on grid-scale storage, battery safety and e-mobility provide useful technical references when developing mitigation strategies. Use these documents to inform hazard analyses and to justify design decisions during planning and procurement. Reference: gov.uk.
