As the use of renewable energy solutions such as PV solar panels and EV charging stations becomes more common on construction sites and completed buildings, new fire risks are emerging. While building regulations focus on fire performance of roofing and cladding materials, recent examples have shown that fires can start within PV arrays or faulty EV units and spread rapidly to the building fabric.
This presents a challenge: compliance with standards such as BS EN 13501-5 and Approved Document B may not fully mitigate the risk of fires starting externally in renewable energy systems. Fire protection guidance now recommends the use of limited-combustibility materials around these installations, but this must be balanced with durability and maintenance requirements.
During our recent Hot Topics CPD session in London, attendees discussed how temporary fire alarm systems, including linear heat detection, can play a vital role in protecting construction sites and welfare units. By providing early detection along rooflines and extended escape routes, these systems can give workers more time to evacuate and reduce the risk of fire spreading.
For further insight into the fire risks associated with renewable energy installations and roofing materials, see the Roofing Today article: Roofing Today – Sept/Oct 2025, page 23.
At Howler, we specialise in designing and installing temporary fire alarm solutions that address modern construction risks, including those posed by renewable energy installations. By integrating regulatory guidance with practical on-site protection, we help clients safeguard both people and property while staying ahead of evolving site safety standards.
