How to Prepare Your Essex Event Venue for the Rising Threat of Solar Panel-Related Fire Risks in 2025

Why solar panel-related fire risks in 2025 matter to Essex venues

Solar panel-related fire risks in 2025 are becoming a pressing concern for Essex event venues. As renewable energy uptake grows, so does the complexity of fire safety at public venues. This guide explains the key hazards, legal duties, practical mitigation steps, and the checks you must carry out now to protect visitors, staff, and assets.

More event venues in Essex are adopting rooftop or ground-mounted photovoltaic systems. Additionally, battery energy storage and hybrid systems are increasingly common. Together, these create new ignition and spread pathways. For example, faulty electrical connections can produce DC arc faults, which are harder to detect and control than AC faults. Therefore, fire behaviour can change and become less predictable.

Moreover, temporary event set-ups, high footfall and limited escape routes increase consequences. A small rooftop fire can force mass evacuation, cause reputational damage and interrupt bookings. Consequently, venue managers and duty holders must act now to reduce risk.

Understand your legal responsibilities and guidance

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must ensure safety for staff and visitors. This duty covers risks introduced by solar installations. Furthermore, other legislation and guidance apply, such as electrical safety duties and building regulations.

“The responsible person must ensure that risks from new systems — including photovoltaics and batteries — are assessed and managed.”

You can consult recognised sources for detailed guidance. The Health and Safety Executive provides general electrical safety advice and hazard information. For fire safety and building standards, consult GOV.UK for official guidance and the National Fire Chiefs Council for operational insight. These references help shape good practice at venues.

How to assess solar panel-related fire risks in 2025 at your Essex event venue

Begin with a full fire risk assessment that includes photovoltaics and batteries. Use a competent assessor who understands electrical risks and PV systems. The assessment should cover:

• PV system design and installation records.
• Battery type, location and communication with the grid.
• Locations of isolators and labelling for first responders.
• Roof access, material compatibility and ventilation.
• Fire spread paths from roof to escape routes.
• Interaction with temporary structures and staging.

Inspectors should check for manufacturer recalls, degraded connectors, and visible damage to modules. For example, micro-cracks or discolouration can indicate increased risk. In addition, evaluate any previous maintenance reports and incident records.

Practical site measures to reduce ignition and spread

Start with basic maintenance. Clean and inspect panels regularly. Check cable glands, fixings and junction boxes for corrosion. Replace damaged connectors promptly. Use only qualified contractors for any electrical work.

Install or confirm labelling. Clear, standardised labels for isolators and battery locations help fire services act fast. Provide roof plans and PV system schematics to the local fire service, and ensure they are updated after changes.

Improve compartmentation where possible. Fire-resisting barriers around service risers and plant rooms limit spread. In addition, keep combustibles away from roof lights, vents and service penetrations.

Ensure safe access and egress. Maintain unobstructed evacuation routes and keep assembly points clear. If you run temporary tents or marquees, enforce a safe distance from PV arrays. Regularly walk through event layouts to spot new risks.

Battery storage and combined systems: special considerations

Battery energy storage systems change the risk profile. They can store high energy and release it quickly. As a result, thermal runaway and re-ignition can occur even after initial extinguishing.

Place batteries in dedicated enclosures where possible. Ensure enclosures have suitable ventilation and cooling. Also, install temperature and smoke detection specific to battery chemistry. For lithium-ion systems, consider remote monitoring and rapid-fire suppression options.

Train staff to treat battery fires differently. For example, water application may be required but only under trained supervision. In all cases, liaise with the fire service on the preferred tactical response.

Fire detection, suppression and firefighter access

Review your alarm and detection systems. Standard smoke detectors may not detect DC arc faults easily. Consider installing specialised detectors or thermal sensors in roof voids and plant rooms.

Assess suppression needs. In some venues, enhanced sprinkler coverage or targeted suppression for plant rooms and battery enclosures is prudent. Where sprinklers are not viable, consider water fog systems or fixed gaseous suppression for electrical risks, in consultation with specialists.

Moreover, provide clear rooftop access for firefighters. Safe access routes and roof hatches speed intervention. Also, ensure lifting equipment and fall protection are available and properly maintained.

Contractor competence and procurement

Only use certified installers for PV and battery work. Ask for proof of competence, accreditation and insurance. Obtain full installation records and electrical test certificates. Keep a copy on file and share essential details with your safety team.

When procuring further work, include fire-safety performance targets in contracts. For example, require attention to cable management, labelling and separation distances. These contractual requirements improve outcomes and reduce liability.

Training, drills and communication

Train staff on new risks. Include PV and battery hazards in induction briefings and safety manuals. Explain how to isolate systems safely and who to contact in an emergency.

Run regular evacuation drills that consider roof and plant fires. Practice communicating with the fire and rescue service. Establish a single point of contact for emergency responders who can provide system schematics on arrival.

Prepare tenant and hirer guidance. If you host third-party caterers or contractors, supply clear rules about hot work, storage and electrical access. For example, prohibit unauthorised roof access and unsupervised hot works near PV arrays.

Record-keeping and monitoring

Keep up-to-date records for all solar-related equipment. Store maintenance logs, inspection reports and warranty papers in a central location. Use digital records where possible for rapid sharing with emergency services.

Install monitoring systems that alert you to performance drops. Sudden changes can indicate faults that might lead to fire. Remote monitoring reduces reaction time and allows prompt remedial action.

Insurance and third-party verification

Notify your insurer about PV and battery installations. Failure to disclose can affect cover. Discuss whether policy adjustments or special endorsements are needed. Some insurers require enhanced inspection regimes for high-capacity storage.

Consider third-party verification from a specialist fire safety consultancy. An independent review will highlight blind spots and provide practical, site-specific recommendations. Total Safe UK can perform these checks and provide tailored reports to support compliance and insurance requirements.

Working with the local fire and rescue service

Engage your local fire and rescue service early. Share site plans and system schematics. Invite them to familiarisation visits. This builds operational knowledge and reduces response time in an incident.

Also, ask for local guidance on access routes and tactical considerations. The fire service can advise on isolator labelling, rooftop hazards and safe assembly points. Their input can inform your mitigation strategy.

Preparing for temporary events and seasonal peaks

Event venues often change layouts. As a result, a PV risk plan must be dynamic. Assess risks before each large event. For example, large stages, lighting rigs and generators can alter ventilation and heat pathways.

During busy seasons, increase inspection frequency. Also, brief temporary staff on PV hazards and the location of isolators. Keep a log of every temporary structure and its proximity to PV arrays.

Next steps for Essex venue managers

Start with a PV-inclusive fire risk assessment. Then, prioritise remedial works that address the highest risks first. Allocate budget for specialist detection, labelling and training. Review insurance cover and maintain a clear line of communication with your local fire service.
