Allianz UK strengthens battery storage underwriting proposition
Allianz UK has expanded its underwriting capability for Battery Energy Storage Systems (BESS) giving brokers specialist support for customers with renewable energy projects.
As the UK accelerates its transition to low-carbon energy, battery storage is becoming an increasingly important part of the infrastructure needed to manage renewable energy generation and strengthen grid resilience.
For brokers, this creates growing demand for insurer partners with the people, experience and confidence to support clients in a fast-moving market.
Developed by Allianz in the UK, leveraging our leading global expertise in energy underwriting, the proposition has been designed for mid-market energy clients and can be tailored to provide customer-led solutions for complex risk features.
Christian Simpson, Head of Construction, Engineering and Energy Insurance, Technical and Underwriting at Allianz UK, said:
“Battery energy storage is becoming an increasingly important part of the UK’s renewable energy infrastructure, and brokers are seeing more clients exploring opportunities in this space. It’s a developing area of risk, which is why early conversations with experienced underwriters and renewable energy specialists are so valuable.
This enhanced proposition underscores Allianz’s commitment to supporting the transition to net-zero solutions by providing comprehensive insurance product for low-carbon technologies and renewable energy projects.
By working closely with Allianz Commercial, we’re giving brokers clearer access to the right expertise across Allianz. We want brokers to feel confident bringing BESS opportunities to us so we can understand each project, look at the controls in place and discuss where we can support both the broker and the customer.”
The announcement forms part of Allianz UK’s wider renewable energy strategy and reflects its commitment to supporting brokers and clients as they respond to the changing energy market. The expanded BESS capability sits alongside Allianz UK’s existing renewable energy expertise across wind, solar, hydro, biomass, anaerobic digestion and short-term operating reserve, giving brokers a clear route to Allianz’s specialist people and capability in this growing sector.
