Labour's plan to encourage millions of homes to be fitted with solar panels (the so-called rooftop revolution) and create more solar farms will lead to more claims. Technology is developing at pace; initial installation costs are high; not all roofs are suitable; safety and fire risks are high; and the skilled workforce is unlikely to be able to meet anticipated output. While the industry gets to grips with all of this, we predict greater risks for insurers that all stakeholders will need to consider. Construction all risks underwriters need to consider their exposure carefully and ensure wordings and premium accurately reflect the risks involved.
