Commercial water damage and business interruption documentation
On a commercial loss the building is only half the claim. The other half is what the closure costs you, and that runs entirely on documentation.
- Two claims: property damage and business interruption
- Phasing work to keep trading where it is safe
- Multi-tenant buildings mean multiple insurers
- Records from day one decide the interruption claim

Two claims, not one
Property damage covers the building, fixtures, equipment and stock. Assessed much as a residential loss, at larger scale.
Business interruption covers lost income during the period the business cannot operate normally, plus continuing expenses that run regardless — rent, salaries, loan payments.
The second is frequently the larger figure and is almost entirely dependent on records. A well-documented property claim with a poorly documented interruption claim leaves substantial money unrecovered.
What the interruption claim needs
- Financial records establishing normal trading — prior periods, same period last year
- A clear record of when operations stopped and when they resumed, including partial resumption
- Documented continuing expenses through the closure
- Evidence of steps taken to reduce the loss — temporary premises, partial operation, extended hours afterwards
- Extra expenses incurred specifically to keep trading
- Contemporaneous notes on cancelled orders, lost bookings, contracts affected
Start that record on day one. Reconstructing it weeks later from memory produces a weaker claim than writing it down as it happens.
Where restoration meets the interruption claim
Our documentation supports both. The same moisture logs and dated scope that justify the property claim also establish how long the space was genuinely unusable — which is exactly what an interruption adjuster is assessing.
Drying records showing equipment on site through specific dates are objective evidence of the closure period, rather than an assertion.
Phasing, and why it matters commercially
On a residential job the goal is to dry the building. On a commercial one it is frequently to dry the building while keeping the business running, which is a different problem.
That can mean working out of hours, isolating a section behind containment so the rest can trade, sequencing so customer-facing areas are restored first, or prioritising stock and equipment before structure.
Tell us your operational constraints on the first call rather than after equipment is placed. What matters most to you — reopening the front, protecting inventory, keeping one department working — shapes the whole plan.
Multi-tenant and landlord situations
A failure in one unit affecting others produces several parallel claims: the building owner's property claim, each tenant's contents and interruption claims, and potentially liability questions between them.
The practical advice is the same as in residential multi-unit buildings and it is worth stating plainly: document your own space immediately and let drying start. Waiting for responsibility to be established is what turns a dry-out into a mold claim four weeks later, and it does not improve anyone's position.
Access to a common riser or a neighbouring unit usually needs the managing agent, so involve them early.
Stock and equipment
Frequently the priority, and worth saying explicitly at the outset. Depending on what it is and how long it has been wet, some can be dried and salvaged and some cannot.
On a sprinkler discharge in a warehouse, moving and drying product sometimes has to precede addressing the structure. That is a legitimate sequencing decision and it needs to be made deliberately rather than by default.
Electronics and machinery: do not power anything on to test it. Applying power to wet equipment is usually what destroys it.
Practical points that are easy to miss
Photograph stock and equipment before moving it, and record serial numbers. Keep every invoice, including temporary premises and extra staffing. Note the date and time operations resumed, even partially. And check whether your policy carries a waiting period before interruption cover begins — many do, and it changes the arithmetic on a short closure.
Questions, answered
What is business interruption cover?
It covers lost income while the business cannot operate normally after a covered loss, plus continuing expenses like rent and salaries. It is frequently the larger part of a commercial claim and it depends almost entirely on financial records and a documented closure timeline.
Can you work around our trading hours?
Usually, at least partly. Out-of-hours work, containment so unaffected areas keep operating, and sequencing customer-facing space first are all normal. Raise your constraints on the first call — it shapes the equipment layout and the plan.
A leak from another unit flooded ours. What do we do?
Document your own space immediately and start drying. There will be several insurers and probably a managing agent involved, and waiting for responsibility to be established costs you material without improving your position. Each affected space gets its own moisture record.
Should we move stock before or after the structure is addressed?
Depends on what it is and how long it has been wet. On a sprinkler discharge in a warehouse, protecting and drying product frequently comes first. Tell us the value and nature of the inventory on the first call so the sequence is deliberate.
