Industrial Unit & Warehouse Insurance
Industrial property is rated on two things a visitor would never notice: what the walls and roof are built from, and what the occupier actually does inside.
The Panels And The Occupier
A large clear span building is cheap to put up and expensive to lose, because fire in a big open volume spreads without the compartmentation a conventional building has. Composite panel construction, which is most of the modern industrial stock, behaves very differently depending on whether the core is mineral wool or a combustible plastic foam, and insurers treat that distinction as decisive rather than technical.
Then there is the tenant. The same unit let to a document storage company, a furniture importer, a battery distributor and a food producer is four different risks, and a landlord who does not know which one is in the building cannot have it insured properly.
What Industrial Unit & Warehouse Insurance Covers
Buildings, including cladding and roof
The structure on a reinstatement basis. On industrial buildings the cladding is a large proportion of the value and the core material of it is a large proportion of the rating.
Loss of rent
Rent lost while the unit cannot be occupied. Industrial rebuilds can be quick, but demolition, clearance and a contaminated site can extend the timeline considerably.
Property owners liability
Claims from tenants, their staff and visitors arising from the building, the yard and the estate common areas. Yards, loading areas and vehicle movements are where these claims actually arise.
Fire protection systems
Sprinklers, hydrants and detection, including the cost of reinstating them after a loss. Where sprinklers are fitted and maintained they usually have a material effect on terms.
Debris removal and environmental clean up
Clearing a burnt out industrial building is expensive, and where the occupier's stock was involved there may be contamination to deal with. These costs are easy to under-set.
Terrorism
Excluded from standard commercial wordings and bought back separately. Commonly required where there is lending against the property.
Where The Cover Stops
Wordings differ between insurers, so treat these as the usual position rather than as universal fact. Where one of them matters to you, it is worth checking on your own schedule before you need to.
Combustible composite panel core
The most significant single factor on modern industrial property. Polyurethane and polystyrene cored panels are rated far more heavily than mineral wool, and some insurers decline them outright or require sprinklers. Not knowing the core material is itself a problem at placement.
Undeclared tenant trade
Cover follows the trade described. A unit declared as general storage and occupied by a company processing or storing something hazardous is a materially different risk, and the landlord is the one holding the policy.
Racking height and storage configuration
High bay storage changes fire behaviour and sprinkler performance. Insurers ask about rack height and aisle width because a sprinkler system designed for one configuration may not protect another.
Empty units
Industrial voids are common and the unoccupancy conditions apply as everywhere else. An empty unit also attracts metal theft, and stripping cable and copper from a vacant building does structural damage well beyond the scrap value.
Yard, external storage and vehicles
Goods and equipment stored outside are often excluded or limited, and the yard is where most liability claims on an industrial estate originate.
Find Out What The Panels Are Made Of
If you own industrial property and do not know the core material of the cladding, that is the first thing to establish, because it affects whether you can be insured at all and at what price.
Mineral wool cored panels behave broadly like a conventional non-combustible wall. Panels with a plastic foam core, typically polyurethane, polyisocyanurate or expanded polystyrene, can contribute fuel to a fire and in a large open building that changes the outcome materially. Insurers have taken a progressively harder line on this, and some will not write buildings with certain cores without sprinklers.
Evidence helps. Original build specifications, a panel manufacturer's certificate, or a surveyor's confirmation all carry more weight than an assurance. Where the building is older and nobody knows, a survey is cheaper than the premium loading applied to an unknown.
The Tenant's Trade Is Your Rating
As a landlord you insure a building, but the building is rated on what happens inside it, and you are relying on the tenant to tell you when that changes.
Lithium battery storage and distribution is the clearest current example. A unit let for general distribution that becomes a battery warehouse is a transformed fire risk, and this has moved quickly enough that plenty of policies describe a trade the tenant no longer carries on. Waste and recycling, tyre storage, foam and furniture, aerosols and paint, and anything involving spraying or heat are the other categories insurers ask about specifically.
Build it into the lease and into your management. A clause requiring the tenant to notify a change of use, and an annual check that the declared trade is still accurate, is the cheapest risk control available on industrial property.
Sprinklers, And Whether They Still Suit The Building
A maintained sprinkler system is the single most effective improvement on an industrial building and insurers price it accordingly. The subtlety is that a system protects the configuration it was designed for.
A sprinkler installation designed for low level general storage may not control a fire in high bay racking, or in a building now storing something with a very different fire load. When the occupier changes or the racking goes up, the question is whether the protection still matches what it is protecting, and that is a question insurers do ask.
Maintenance records matter as much as the system. Where sprinklers are a condition of the terms, servicing certificates and valve checks are the evidence that the condition was met, and they are the first thing requested after a fire.
How To Choose Cover For Industrial Property
Industrial is the property class where the gap between a well placed and a badly placed risk is widest, because the rating factors are technical and a generic quote hides them. We are an FCA regulated broker and will not claim to be the best choice. This is what decides it.
Did they ask about the panel core before quoting?
A quote for a modern industrial building produced without asking about composite panel core material has been priced on an assumption. That assumption surfaces at claim stage.
Do they know the tenant's actual trade, not the one on the lease?
Leases describe permitted use; tenants do what they do. A broker who asks what is physically in the unit is asking the question the insurer will ask after a fire.
Is there a change of use notification process?
Industrial risk changes when the occupier changes. Ask how that gets to the insurer, and whether the lease supports it.
Have they assessed whether the sprinklers suit the current use?
A system designed for one storage configuration may not protect another. This is the question that separates a technical placement from a renewal rolled forward.
Is clean up and debris removal realistically set?
Clearing a burnt out industrial building, potentially with contaminated residues, is a large cost that is routinely under-set because it is not the headline number.
Factually, we ask for panel construction and the occupier's actual trade before approaching the market, we flag where a sprinkler installation may no longer match the use, we set debris removal and clean up as considered figures rather than defaults, and we ask landlords to tell us when a tenant changes rather than finding out at renewal. We are a broker, so it goes to several insurers rather than one, and industrial is a class where that difference shows.
What Moves The Price
Property of this kind is priced on the building and the way it is used rather than on a tariff, so a published figure would tell you nothing. What we can tell you is what the premium is actually built from.
- Composite panel core material, which is often the decisive factor
- The occupier's actual trade and what is stored
- Sprinklers and whether they suit the current configuration
- Building size, clear span and compartmentation
- Racking height and storage arrangement
- Void periods, estate security and claims history
We are a broker, so we take it to several insurers rather than quoting one. Call 02382 000820 for a quote.
What We Need To Quote
- Address, reinstatement value and floor area
- Construction, including composite panel core material if known
- The tenant's actual trade and what is stored on site

Common questions
Why do insurers ask about composite panels on a warehouse?+
Because the core material changes how a fire behaves in a large open building. Mineral wool cored panels act broadly like a non-combustible wall. Plastic foam cores, typically polyurethane, polyisocyanurate or polystyrene, can add fuel to the fire, and in a clear span building with no compartmentation that changes the outcome. Some insurers decline certain cores outright or require sprinklers, so establishing what you have is the first step rather than a detail.
Does my tenant's trade affect my landlord insurance?+
Substantially. You insure the building but it is rated on what happens inside it. A unit let for general distribution that becomes lithium battery storage is a transformed fire risk, and the policy still describes the old trade. Waste and recycling, tyre storage, foam, aerosols and any process involving heat are the categories insurers ask about specifically. A lease clause requiring notification of a change of use is the practical control.
Who insures warehouses and industrial units in the UK?+
Most commercial property insurers will write industrial, but the terms vary enormously with construction and occupancy, and the ones that will write combustible cored panels or higher hazard trades are a narrower set. This is a class where going to several insurers changes the outcome rather than shaving the price, which is the main argument for using a broker on it at all.
Do sprinklers reduce warehouse insurance premiums?+
A maintained system usually has a material effect on terms, and on some risks it is the difference between terms and a decline. The caveat is that a sprinkler installation protects the configuration it was designed for, so if racking height or the stored goods have changed, the question is whether the protection still matches the use. Servicing records are what evidence the condition was met.
What happens if my industrial unit stands empty?+
The usual unoccupancy conditions apply, narrowing cover after a continuous period of 30 or 45 days, typically removing escape of water, theft and malicious damage. Empty industrial units also attract metal theft, and stripping cable and copper causes structural damage far exceeding the scrap value. Tell the insurer before the unit goes empty, and secure and inspect it to the conditions stated.
Is stock stored outside in the yard covered?+
Often not, or only to a limited amount. Goods and equipment in the open are usually excluded or sub-limited, and need declaring specifically if they matter. The yard is also where most liability claims on an industrial estate arise, from vehicle movements and loading rather than from anything inside the building.
