Despite a softening insurance market, inflation continues to increase the cost of rebuilding, repairing and replacing assets. Brokers should encourage customers to regularly review sums insured, indemnity periods and asset valuations to help ensure cover remains aligned with current exposures and replacement costs.

Lower insurance premiums should not be interpreted as lower risk. The gap between falling rates and rising replacement costs can increase the likelihood of underinsurance if valuations are not reviewed regularly. (Source: marsh.com)

Supply chain disruption

Ongoing supply chain disruption can prolong recovery times following a loss, increasing the importance of reviewing business interruption indemnity periods and contingency planning. Brokers may wish to discuss whether customers' current cover reflects the longer timescales now associated with repairing, rebuilding or replacing critical assets.

Food inflation, driven by global conflict, energy costs and supply-chain disruption, is expected to hit 9-10% by late 2026. (Source: The Food and Drink Federation)

Approximately 80% of fruit and nearly half of vegetables consumed in Britain are imported and many of the supplying regions are also experiencing heat and water stress leading to a lack of resilience in supply chains and anticipated increases to costs and availability of produce.

Rising food, fuel and supply costs can increase stock values and business operating costs. Brokers should encourage customers to review declared values regularly, particularly where stock levels, inventory values or supply-chain dependencies have changed significantly over the last 12 months.

Steel is currently one of the clearest areas of inflation as it is being affected by energy costs, raw-material costs and international trade conditions. (Source: Eurometal)

Construction material inflation continues to place pressure on rebuild costs. Businesses that have not reviewed valuations recently may find declared values no longer reflect true replacement costs, increasing the risk of underinsurance in the event of a major loss. Professional valuations and regular reviews remain important.

Building costs are forecast to rise 15% over the next five years. (Source: BCIS)

Construction output is forecast to grow by approximately 11% in 2027, driven by infrastructure, retrofit and a gradual recovery in private-sector development. (Source: London Construction Magazine)

Higher labour and energy costs continue to increase production and transportation costs for businesses. Many firms report rising staffing costs and ongoing concerns about energy and fuel prices, while supply chain disruption is also expected to increase transportation costs. [Source: ons.gov.uk], 

Growth in construction activity, combined with higher material, labour and transportation costs, reinforces the need for regular reviews of contract values, rebuilt values and project timelines. Brokers can play an important role in helping customers ensure cover keeps pace with changing project costs and exposures.
