What makes commercial claims different
A business loss has two layers. The first is physical: buildings, fit-out, stock, plant and equipment. The second is financial: the gross profit that disappears while the business is disrupted, the extra costs paid to keep trading, and sometimes penalties or lost contracts. Each layer has its own valuation logic and its own policy wording.
Commercial policies also contain more conditions than household cover: sums insured per item, indemnity periods, declared values, average or underinsurance clauses, waiting periods and specific exclusions. Misreading one of them can change the settlement considerably.
Losses covered by these guides
The pages listed below follow the main types of commercial cover and the expertise each one requires.
- Commercial property damage to premises, stock and contents
- Business interruption and loss of gross profit after an insured event
- Machinery breakdown and electrical damage to production equipment
- Industrial risk programmes for plants, warehouses and multi-site groups
- Cyber incidents, data restoration and resulting business disruption
- Pollution and environmental damage linked to an operation
The professionals usually involved
On large files the insurer generally appoints a loss adjuster, who may in turn instruct forensic accountants, engineers or IT specialists. On the policyholder's side, a public adjuster, loss assessor or independent claims expert can coordinate the company's own specialists, prepare the quantification and negotiate. The titles and the rules on who may act for a policyholder differ from one country to another.
Where the numbers are usually contested
Disputes tend to concentrate on the trend used to project lost revenue, the length of the indemnity period actually needed, savings the insurer deducts, whether stock is valued at cost or selling price, and whether repaired equipment is truly back to its former condition. Underinsurance discovered after the loss is another frequent source of tension.
How to navigate this section
If the main issue is damage to buildings or contents, begin with the commercial property guide. If revenue is the bigger concern, go to business interruption. Equipment failures belong to machinery breakdown or electrical damage, while digital incidents are covered on the cyber page. For complex sites with several exposures, the industrial risk guide gives a wider view. Each subject has a related page on how independent experts charge for this type of work.
Preparing the company for the claim
Name one internal contact for the insurer, preserve damaged items and logs, separate claim-related costs in the accounts from day one, and gather recent management accounts, budgets and order books. Clear records shorten the adjustment and reduce arguments about assumptions.
Large losses and multi-policy programmes
Groups with several sites often buy a master programme with local policies underneath, sometimes placed with different insurers or through a captive. After a major event, the allocation of the loss between property, interruption, machinery and liability covers can become a negotiation in itself. Deductibles may apply per site, per event or in aggregate, and the order in which they are applied affects the net recovery.
In such files, an interim payment schedule agreed early helps the business keep paying suppliers and staff while the final figures are worked out. Requests for interim payments should be supported by a short, credible estimate rather than a single global figure, and each payment should be documented as on account of the final settlement.

Frequently asked questions
Does business interruption pay without physical damage?
Usually not under standard wording, which requires insured damage first. Some extensions cover specific events such as denial of access or supplier failure, depending on the contract.
Should our accountant prepare the claim?
Your accountant provides essential data, but a claims specialist knows how policy definitions of gross profit and savings translate those figures into an insured amount.
When is an independent expert most useful?
On losses with a large financial component, several policies or disputed indemnity periods, where technical and accounting arguments must be built in parallel.
