Finding low cost commercial insurance is a top priority for many business owners and landlords. But while saving money is important, it’s just as crucial to make sure your policy gives you the right protection. The cheapest option might not cover everything you need – especially when it comes to rebuild costs, liability cover, and policy exclusions.
With insurance prices going up and many businesses at risk of being underinsured, knowing what affects your commercial building insurance costs can help you make a smart choice. This guide explains the key factors that impact pricing, clears up common misunderstandings, and shows you how to get affordable commercial insurance without sacrificing essential coverage.
Why understanding commercial building insurance matters
Owning a commercial property comes with financial risks. Without the right insurance, damage from fire, flooding, or structural issues could leave you with huge costs. Commercial building insurance helps protect business owners and landlords by covering repair costs, rebuild expenses, liability claims, and lost rental income.
But many businesses are underinsured – often realising too late. Our data shows that up to 79% of UK commercial properties don’t have enough cover, putting owners at risk of financial loss.
Do you have the right cover?
Many landlords believe their policy is enough – until they need to claim. A common mistake is confusing market value with rebuild costs, leading to inaccurate commercial building insurance quotes. You can learn how to make sure your policy reflects the true cost of rebuilding here.

How much does commercial building insurance cost?
Commercial building insurance isn’t the same for everyone. Your premium depends on several factors, including your property type, location, and the level of risk insurers attach to it. Understanding these factors can help you better compare policies and find the right cover.
Common misconceptions about low cost commercial insurance
Many property owners wrongly believe that market value equals rebuild cost. This mistake can lead to inadequate cover. Some rely on a commercial building insurance calculator, expecting an exact rebuild cost. But these tools often oversimplify estimates and don’t always consider:
Building structure – Older buildings or those with special materials may cost more to rebuild.
Listed or unique properties – These often require expert valuations.
Changing material and labour costs – Prices can rise over time, affecting rebuild expenses.
Relying on an online calculator alone could leave your property underinsured. Premiums don’t just depend on the building itself. To make sure your policy provides the right cover, it’s essential to base your sum insured on an accurate rebuild valuation.

Key factors that affect commercial building insurance costs
Property type & rebuild cost
A high-rise office in a city costs more to rebuild than a small shop in a rural town.
Larger or older buildings are often more expensive to insure due to higher rebuild costs.
Listed or specialist properties may need tailored insurance, which increases premiums.
Some insurers calculate commercial building insurance cost per square foot, based on location, materials, and risk.
Location & risk factors
Insurers assess risks like flooding, subsidence, and crime rates in your area.
Properties in flood-prone zones usually have higher insurance costs.
City centre buildings may also face increased premiums due to higher liability risks.
Business type & liability cover
A warehouse with few visitors has a lower risk than a restaurant or shop with daily customers.
Some industries require extra liability insurance, which increases overall costs.
How insurers calculate premiums
Insurers look at rebuild costs, location, and business type to set your premium.
Choosing a higher deductible can lower your premium but means paying more if you claim.
Wear and tear is not covered in most cases – owners are responsible for maintenance costs.
So, what can help? It’s important to regularly review your rebuild cost, to ensure you’re not overpaying or leaving your property underinsured. Comparing providers can also help you find affordable commercial building insurance quotes that offer the right level of protection without unnecessary costs.
Comparing insurance costs by property type
Property Type | Typical Insurance Cost Trend |
Retail Shop | Moderate – higher foot traffic increases liability risks. |
Office Building | Lower – generally lower fire and damage risks. |
Warehouse | Lower – fewer liability risks but affected by location factors. |
Restaurant/Pub | Higher – increased fire risk and public liability exposure. |
Industrial Unit | Variable – depends on the machinery and processes used. |

Types of commercial building insurance & coverage options
Picking the right commercial building insurance means knowing what is covered – and what isn’t. Different policies protect against different risks, so it’s important to choose one that matches your business needs.
What’s covered?
Most commercial property insurance policies include these key types of cover:
Buildings Insurance vs. Contents Insurance
Buildings insurance covers damage to the structure caused by fire, floods, storms, or vandalism.
Contents insurance protects fixtures, fittings, and equipment owned by the landlord.
Public Liability & Employer’s Liability
Public liability insurance covers claims if someone is injured on your property.
Employer’s liability insurance is required by law if you have staff. It covers workplace injuries and illness claims.
Business Interruption Cover
Business interruption insurance helps if your business has to close due to an insured event, like fire or flood damage. It can cover lost income during this time.

Customising your policy
Every business faces different risks. A standard commercial building insurance policy covers the basics, but you may need extra protection. Here are some optional add-ons to consider:
✔ Accidental Damage Cover – Protects against unexpected damage that isn’t caused by wear and tear.
✔ Loss of Rent Cover – Ensures landlords still receive rental income if the property becomes uninhabitable.
✔ Terrorism Cover – Covers damage caused by terrorist incidents, which is often excluded from standard policies.
✔ Unoccupied Property Insurance – Essential if your property will be empty for a long period.
What’s not covered?
Not all policies cover every risk. If you don’t check exclusions, you could face unexpected costs when making a claim. Common exclusions include:
Gradual wear and tear
Poor maintenance or neglect
Damage from events that aren’t insured (e.g., some natural disasters)
Reading your policy terms carefully helps ensure there are no hidden gaps in your cover.
How to compare & choose the right insurance provider
Selecting a commercial property insurance provider isn’t just about finding the lowest price – it’s about ensuring reliable coverage, fair claims handling, and financial security when you need it most. Many business owners make the mistake of focusing solely on cost, only to face unexpected policy gaps or claim delays.
Checklist: How to choose the right commercial property insurance provider
Finding low cost commercial insurance with the right coverage can be tricky. Use this checklist to compare providers and avoid common mistakes.
What to look for
✔ Does it cover everything you need? Look for policies that cover your rebuild costs, include liability cover, business interruption, and unoccupied property protection.
✔ Are the costs clear? Some policies have hidden fees. If a deal looks too cheap, check for missing coverage.
✔ Is the claims process fair and fast? Some insurers delay payouts or make claiming difficult. Read reviews and check how quickly claims are settled.
✔ Is the provider trusted? Look at customer reviews, case studies, and industry ratings to see if the insurer is reliable.
✔ Is the provider financially secure? Make sure they are regulated by the Financial Conduct Authority (FCA). This helps protect your investment.
Understanding the average clause & underinsurance risks
Even with a trusted insurance provider, underinsurance is a major risk for commercial property owners. Many policies include an "average clause," which can reduce claim payouts if your property is underinsured.
Here’s how it works:
If your property is insured for only 50% of its true rebuild cost, your insurer may only pay 50% of any claim.
This means you would have to cover the rest of the costs yourself.
This clause can leave you financially exposed if disaster strikes.

Not all policies are created equal
A low-cost commercial insurance policy means nothing if your insurer delays or denies claims when you need them most. Choosing a trusted provider with transparent pricing and strong claims handling is key to protecting your property.
Save money & get the best coverage
Many business owners assume their commercial property is fully covered – until they file a claim and find out otherwise. Underinsurance is a persistent problem, with our data suggesting that up to 79% of UK commercial properties underinsured (latest industry infographic). The financial consequences can be devastating, leaving property owners responsible for unexpected shortfalls.
