Commercial insurer QBE warns solar panel fires are increasing across UK domestic and commercial properties, highlighting installation and maintenance risks.
Commercial insurer QBE has issued a warning regarding a significant increase in fires linked to solar panel installations across the UK. The insurer highlighted that incidents are escalating in frequency and severity across residential dwellings, commercial units, and industrial buildings, with fires spreading more readily across affected structures.
The growth in solar photovoltaic adoption has accelerated across the UK building sector, driven by net-zero targets and high energy costs. However, the rise in property claims points toward critical vulnerabilities in component quality, system isolation, and installation practices. Poorly fitted connectors, DC isolator faults, and inadequate thermal management behind panels are frequently cited as key triggers for roof-space fires.
For electricians, roofers, and solar installers, this warning signals impending scrutiny on installation standards, sign-offs, and component sourcing. Installers should avoid unbranded DC isolators and cheap connector units often bundled in budget kits, opting instead for certified components from established trade merchants. Electricians must ensure strict adherence to MCS standards and thorough testing of DC cabling, as insurers are increasingly likely to challenge claims linked to substandard installations. DIYers attempting retrofits should take note that self-installation without full certification could invalidate home insurance policies.
Roofing and electrical contractors should incorporate strict thermal inspection routines and routine maintenance checks into their service packages. Ensure all isolators and cabling are correctly rated and adequately protected from environmental degradation to limit fire risks.
