What Is Commercial Property Insurance?
Commercial property insurance provides financial protection for the buildings and contents of business premises in the UK. It covers the cost of repairing or rebuilding a commercial property following damage from insured events such as fire, flood, storm, or escape of water, and replaces business contents and equipment if they are damaged, destroyed, or stolen.
Unlike domestic home insurance, commercial property insurance is designed to reflect the specific risks associated with business use: higher footfall, specialised equipment, complex fit-outs, and the financial consequences of being unable to trade following a loss. The policy structure and underwriting approach differ significantly from residential insurance.
Who needs it: Commercial property insurance is relevant to any business that owns or occupies commercial premises — whether a shop, office, warehouse, restaurant, or industrial unit. It is also relevant to property investors and landlords who own commercial buildings let to business tenants.
Buildings vs Contents Insurance
Commercial property insurance typically comprises two distinct elements: buildings insurance and contents insurance. These can be arranged separately or combined into a single policy.
| Element | What It Covers | Who Arranges It |
|---|---|---|
| Buildings insurance | The structure of the building, including walls, roof, floors, fixed fixtures and fittings, and outbuildings | The property owner (freeholder or head leaseholder) |
| Contents insurance | Furniture, equipment, stock, computers, and other moveable items within the premises | The business occupying the premises (tenant or owner-occupier) |
Where a business owns its own premises, it will typically need both buildings and contents insurance. Where a business rents its premises, the landlord is usually responsible for buildings insurance, and the tenant is responsible for insuring their own contents and equipment. Lease terms should always be reviewed to confirm the insurance obligations of each party.
What Does It Cover?
A standard commercial property insurance policy covers damage arising from a range of specified perils. The exact scope varies between insurers and policy wordings, but typically includes:
| Peril | What Is Covered |
|---|---|
| Fire and explosion | Structural damage and contents loss caused by fire, including smoke damage and firefighting efforts |
| Storm and flood | Damage from severe weather, including roof damage, flooding, and fallen trees |
| Escape of water | Damage caused by burst pipes, leaking appliances, or water tank failures |
| Theft and vandalism | Theft of contents and damage to the building caused during a break-in or by vandalism |
| Subsidence | Structural damage caused by ground movement beneath the building |
| Impact damage | Damage from vehicles, falling aircraft, or falling objects |
| Accidental damage | Unintentional damage to the building or contents (often available as an optional add-on) |
Some policies are written on an "all risks" basis, which provides broader cover for any sudden and unforeseen physical loss or damage, subject to specific exclusions. This is generally preferable to a "specified perils" policy, which only covers the events explicitly listed.
Reinstatement Value and Underinsurance
The sum insured for commercial buildings insurance should reflect the reinstatement value — the cost of demolishing the existing structure and rebuilding it to the same specification, including professional fees, site clearance, and compliance with current building regulations. This is distinct from the market value of the property.
Underinsurance is a significant risk in commercial property insurance. If the sum insured is set below the true reinstatement value, insurers may apply the principle of "average" — reducing any claim settlement proportionally. For example, if a property is insured for 70% of its reinstatement value, a claim may only be settled at 70% of the loss.
Reinstatement cost assessments: For significant commercial properties, a professional reinstatement cost assessment (RCA) carried out by a chartered surveyor provides an accurate rebuild cost figure and reduces the risk of underinsurance. RCAs should be updated periodically to reflect changes in construction costs.
Contents sums insured should reflect the full replacement cost of all business equipment, furniture, stock, and other contents at current prices — not the original purchase price or depreciated value, unless the policy is written on an indemnity basis.
Business Interruption Insurance
Business interruption insurance (also known as consequential loss insurance) covers the financial losses a business suffers when it is unable to trade following an insured event. If a fire destroys a commercial premises, the buildings and contents insurance covers the cost of reinstatement — but business interruption insurance covers the lost revenue and additional costs incurred while the business is unable to operate.
Key elements of business interruption cover include:
- Loss of gross profit or revenue during the period of interruption
- Increased costs of working — additional expenses incurred to maintain trading (e.g., temporary premises, additional staff)
- Wages for employees who cannot work during the interruption period
- Cover for the indemnity period — the maximum period for which claims can be made, typically 12, 24, or 36 months
The indemnity period should be set to reflect the realistic time required to reinstate the premises and return to normal trading. For complex commercial properties, this can be significantly longer than many business owners assume.

Types of Commercial Property
Commercial property insurance is available for a wide range of property types. The underwriting approach and premium will vary depending on the nature of the premises and its use:
| Property Type | Key Considerations |
|---|---|
| Offices | Lower risk profile; cover for IT equipment and business contents is important |
| Retail premises | Stock cover, public liability, and business interruption are key; security requirements may apply |
| Warehouses and industrial units | High stock values, forklift and machinery risks, and fire suppression systems affect underwriting |
| Restaurants and hospitality | Commercial kitchen risks, food stock, and loss of licence cover are relevant |
| Mixed-use properties | Combination of residential and commercial use requires careful policy structuring |
| Listed buildings | Higher reinstatement costs due to specialist materials and craftsmanship requirements |
Lease Obligations and Tenant Responsibilities
Commercial leases typically contain specific provisions relating to insurance. Common arrangements include:
Under a full repairing and insuring (FRI) lease, the tenant is responsible for maintaining the property in good repair and may also be required to reimburse the landlord for the cost of buildings insurance via a service charge. The landlord arranges the buildings insurance, but the cost is passed to the tenant.
Under an internal repairing and insuring (IRI) lease, the tenant is responsible for internal repairs and their own contents, while the landlord retains responsibility for the structure and external repairs.
Tenants should always review their lease carefully to understand their insurance obligations and ensure that their policy meets any requirements specified in the lease. Failure to maintain required insurance may constitute a breach of lease.
Liability Cover for Property Owners
Property owners have a legal duty of care to ensure that their premises are safe for occupants, visitors, and members of the public. Property owners' liability insurance (also known as premises liability) covers legal liability for injury or property damage to third parties arising from the ownership or occupation of the premises.
For businesses that occupy their own premises, public liability insurance typically covers both the business activities and the premises. For landlords who let commercial premises to tenants, property owners' liability insurance is arranged separately to cover the landlord's obligations as property owner.
Getting Covered
Arranging commercial property insurance through a specialist broker gives you access to insurers who understand the specific risks associated with different types of commercial premises. A broker can help you establish the correct reinstatement value, identify the right policy structure, and ensure that all relevant disclosures are made correctly.
When approaching a broker, it is helpful to have the following information available:
- The address and type of each property to be insured
- The year of construction and construction type
- The current use of the property (owner-occupied, let, or mixed)
- The reinstatement value or rebuild cost estimate
- The total value of business contents and stock
- The annual turnover of the business (for business interruption cover)
- Details of any claims in the past five years
- Details of any unusual features (e.g., listed building status, flat roof, hazardous processes)
