BUSINESS INTERRUPTION COVER THAT KEEPS YOUR FACTORY ALIVE
What Is Business Interruption (BI) Insurance?
Business interruption (BI) insurance is designed to protect your business’s income after a major insured event damages your premises or equipment and prevents you from trading normally. For metal and engineering manufacturers, BI is often the difference between “we’ll survive this” and “we’ll never recover”.
A fire, flood, theft, escape of water or serious damage can stop production overnight. Even if your property policy pays for repairs, you still have a problem: wages, rent, finance costs, and overheads continue while output drops. Customers may move to alternative suppliers if you can’t deliver. That’s the gap BI is intended to fill — by replacing lost gross profit and supporting recovery costs.
The key is structuring BI for engineering reality: replacement lead times for CNC machines and specialist plant, commissioning and calibration time, tooling rebuild, supplier dependencies, and the “bottleneck machine” that holds the schedule together.
Why BI Matters in Metal & Engineering Manufacturing
Engineering manufacturers are capital intensive. You rely on machines, power, compressed air, extraction, tooling, metrology, and often skilled staff who can’t be replaced easily. A major loss doesn’t just damage buildings — it breaks the production system: capacity, capability and delivery.
The financial impacts can include lost revenue, wasted labour, cancelled orders, expedited purchasing, outsourcing costs, and long-term customer churn. If your business is contract-driven, missed milestones can also create disputes and penalty pressure. BI isn’t a “nice-to-have”; it’s one of the most important covers for manufacturers with meaningful overheads and delivery obligations.
BI can also be used strategically. With the right increased cost of working cover, you can justify recovery actions that keep customers supplied: temporary premises, overtime, additional shifts, outsourcing, hiring replacement plant, or expedited freight for critical orders.
- Replaces lost gross profit after insured damage
- Supports wages and overheads during downtime
- Funds recovery actions (outsourcing, overtime, temporary premises)
- Reduces risk of losing key customers due to delivery failure
- Accounts for machine lead times and re-commissioning
- Aligns to “bottleneck” machines and single points of failure
What Does BI Insurance Pay For?
BI policies can vary by insurer and wording, but the core concept is consistent: if you suffer insured damage that interrupts trading, BI helps replace your lost gross profit for the indemnity period (the time it takes to return to “normal” output).
Many BI policies also include “Increased Cost of Working” (ICOW). This is critical for manufacturers because it funds the steps you take to keep trading: overtime, outsourcing, hiring additional machines, renting temporary premises, or expediting suppliers. Done properly, ICOW is a practical tool, not just a technical clause.
BI can also include additional extensions depending on needs: denial of access, supplier/customer dependencies, loss of utilities, and sometimes interruption following machinery breakdown where offered. The right mix depends on your “failure modes”.
- Loss of gross profit during the indemnity period
- Standing charges / overheads (where included in gross profit basis)
- Increased cost of working (outsourcing, overtime, temporary premises)
- Extra expenses to reduce loss and maintain customer supply
- Optional extensions: denial of access, supplier/customer dependency
- Utilities interruption options (power/water dependency) where available
The Two Biggest BI Mistakes: Underinsuring Gross Profit and Choosing Too Short an Indemnity Period
BI claims often go wrong for two reasons: the gross profit sum insured is too low, or the indemnity period is too short. Both are common in manufacturing because businesses underestimate how long recovery actually takes.
Engineering recovery timelines are influenced by factors beyond building repairs: machine lead times, import delays, control systems, electrical work, compressed air and extraction reinstatement, re-commissioning, calibration, quality requalification, and rebuild of tooling and fixtures. For specialist CNC or automation equipment, lead times can be substantial.
If your BI indemnity period is 12 months but your realistic recovery is 18–24 months, you can run out of cover before you’re back on your feet. That’s a silent failure — the policy exists, but doesn’t last long enough. We help clients model realistic downtime and structure BI accordingly.
- Gross profit often underestimated (especially when turnover is growing)
- Indemnity period should match realistic engineering recovery timelines
- Machine lead times and commissioning can exceed building repairs
- Calibration, qualification and capability rebuild take time
- Bottleneck machines can define the true recovery duration
- A structured BI review can reduce disputes and improve outcomes
Engineering BI Needs to Consider “Bottleneck” Risk
Many manufacturers have one or two critical constraints: a single CNC machine, a heat treatment process, a coating line, a test rig, a laser cutter, or a specialist grinder that determines output. If that bottleneck is damaged, the whole factory slows down. If it’s not damaged, you may recover faster than expected by moving work around.
A good BI plan identifies bottlenecks and builds contingencies: alternative suppliers, outsourcing options, machine rental, or redundancy strategies. BI insurance supports this because increased cost of working can fund outsourcing or accelerated production.
Underwriters respond well when you can demonstrate you understand your bottlenecks and have credible recovery options. This can improve not only claim outcomes, but also underwriting terms.
- Identify the machines/processes that constrain throughput
- Model downtime based on bottleneck replacement timelines
- Use ICOW to fund outsourcing and keep customers supplied
- Consider single points of failure (power, compressors, extraction)
- Build contingencies for tooling, programming and quality capacity
- Demonstrate recovery planning for better underwriting confidence
BI Extensions That Often Matter for Manufacturers
Beyond the standard “damage at your premises” scenario, manufacturers can suffer interruption from other events. Depending on insurer and wording, BI can sometimes be extended to cover additional triggers.
Examples include denial of access (e.g., the premises is cordoned off), loss of utilities (power outage affecting production), and dependencies on key suppliers or customers. These extensions must be chosen with care — you want cover that matches your exposures, not generic bolt-ons.
We’ll help you identify the extensions most likely to materially affect your business and then structure them within a coherent programme.
- Denial of access / prevention of access options
- Utilities and services interruption (power, water) where available
- Supplier dependency (critical material or subcontract process)
- Customer dependency (where a small number drive revenue)
- Interruption at third-party storage locations (where stock is held)
- Engineering breakdown-trigger BI options (when offered)
How We Help You Structure BI Properly
Business interruption should be structured, not guessed. We’ll typically work through: your turnover and gross profit basis, your key costs and dependencies, your bottleneck machines, and your realistic recovery timeline after a worst-case loss.
For engineering businesses, this often includes reviewing: machine schedules and values, lead times, supplier dependencies, calibration and testing requirements, and whether outsourcing or temporary premises is feasible. Once that’s mapped, we can recommend a BI sum insured and indemnity period that fits your business — and present it clearly to insurers.
This process often leads to better outcomes: fewer disputes, fewer undervaluation issues, and smoother claims. It can also reduce premium volatility because insurers see that your BI values are evidence-based.
- BI sums insured based on realistic gross profit calculations
- Indemnity periods aligned to machine lead times and capability rebuild
- ICOW structured to support outsourcing and rapid recovery actions
- Better clarity for underwriters = fewer restrictive terms
- Joined-up with property values, machinery breakdown and supply chain risk
- Renewal-ready BI story to reduce premium surprises
Our building could be repaired in months — but replacing and commissioning our key machines would take much longer. Insure24 helped us restructure BI with a realistic indemnity period and enough increased cost of working to outsource and keep customers supplied.

FREQUENTLY ASKED QUESTIONS
+-
What does business interruption insurance cover for manufacturers?
BI typically covers loss of gross profit following insured damage (such as fire or flood) that interrupts trading. It can also include increased cost of working to fund recovery actions like outsourcing and overtime, subject to policy terms.
+-
How do we choose the right indemnity period?
Engineering recovery is often defined by machine lead times, commissioning and calibration, tooling rebuild and quality requalification. Many manufacturers choose 12, 18, 24 or 36 months depending on how long a worst-case recovery would realistically take.
+-
What is “increased cost of working” (ICOW)?
ICOW funds extra costs you incur to reduce the interruption and keep trading, such as outsourcing, overtime, temporary premises, hiring replacement plant, or expedited freight. It’s a key part of BI for manufacturing businesses.
+-
How is the BI sum insured calculated?
It’s typically based on your annual gross profit (and sometimes adjusted for trends and growth), multiplied by the chosen indemnity period. Getting the gross profit basis right is critical — undervaluation can lead to reduced claim payments.
+-
Can BI cover losses caused by a supplier problem or power outage?
Standard BI usually requires damage at your premises, but policies can sometimes be extended for supplier/customer dependency, denial of access, or utilities interruption (depending on insurer and wording). We’ll recommend extensions based on your real exposures.
+-
Is BI included automatically with property insurance?
Not always. BI is often selected as an additional section of a property policy and must be set up with the correct gross profit, indemnity period and extensions. Many businesses discover they have no BI (or inadequate BI) only when reviewing a claim scenario.
+-
What information do you need to quote BI for an engineering manufacturer?
Typically: turnover and gross profit, key overheads, growth trends, property and plant values, key/bottleneck machines and lead times, dependency on utilities/suppliers/customers, and your realistic recovery plan after a major loss.
