For many SMEs, the biggest lesson of recent years has been that even well-run businesses are only as resilient as their supply chains. From raw materials to finished goods, any disruption in the chain can halt operations, slash revenue and damage client relationships.
Business Interruption (BI) insurance has traditionally focused on risks like fire or flood. But in today’s interconnected world, many interruptions are caused by third parties, suppliers, distributors, logistics providers, or overseas manufacturers. This is where extended business interruption cover, including contingent BI, comes into play.
The Modern Supply Chain Challenge
- Global dependence: SMEs often source materials from abroad to cut costs. This introduces exposure to geopolitical risk, trade disputes, or shipping delays.
- Single supplier reliance: Many firms use just one or two suppliers for critical components: creating a bottleneck.
- Inflation & cost volatility: A delay in one part of the chain can cause cascading costs, including expedited shipping and storage fees.
Where Standard BI Coverage Falls Short
Traditional BI policies usually respond to physical damage at the insured premises (e.g., fire shutting down operations). However:
- They may not cover disruptions caused at a supplier’s premises.
- They may exclude “non-damage” events such as port strikes or cyber-attacks on suppliers.
This means SMEs relying heavily on supply chains could be left unprotected.
Contingent Business Interruption (CBI) Insurance
What it is:
CBI extends BI coverage to include losses resulting from damage at the premises of suppliers, customers, or other dependent entities.
Why it matters:
- If a supplier’s factory floods in another country and you can’t get raw materials, your cover responds.
- If a key customer site is destroyed and they stop buying, CBI can help bridge your lost sales.
Real-World Example
A UK furniture manufacturer imports timber from a single supplier in Eastern Europe. When severe flooding halts the supplier’s operations, shipments stop for two months.
- Without contingent BI: the manufacturer faces lost orders, idle staff and no cover.
- With contingent BI: their policy pays for lost income during the downtime and helps cover extra costs (like sourcing alternative suppliers).
Practical Steps
- Map your supply chain: Identify your top five suppliers and customers.
- Check your BI policy: Does it include contingent extensions? If not, speak to your broker.
- Review limits and indemnity periods: Global disruptions often last months, not weeks.
- Add crisis planning: Insurance is vital, but having back-up suppliers reduces reliance.
Why This Matters Now
- Recent years have seen Red Sea shipping route disruptions, Brexit-related customs delays, and material shortages in construction.
- SMEs without robust BI protection risk cashflow crises, even if their own premises are unaffected.
Supply chain fragility is here to stay. Businesses that only insure against direct property damage are leaving themselves exposed to hidden business interruption risks.
Next step:
- Review your BI cover with a broker.
- Ask whether contingent BI and non-damage extensions (like denial of access or cyber-triggered events) should be added.
