How this directory is compiled
This directory lists established UK insurers that underwrite commercial building and commercial property cover, sorted alphabetically with no ranking implied. Inclusion is based on a firm being an FCA-authorised insurer active in the UK commercial property market, drawn from the FCA Register and the insurers' own material.
Each entry below was confirmed on the FCA Register at register.fca.org.uk at the time of writing, and the firm reference number is shown. Where a reference could not be independently confirmed for a specific entity, it is marked for verification. The directory does not rate, rank, or recommend any insurer; it provides a verifiable starting point for buyers and their brokers.
Commercial building cover is frequently arranged through brokers rather than bought directly, so the listed insurers may be accessed via an FCA-authorised intermediary. Re-verification is recommended before any cover is placed, as authorisation status can change.

How to verify a provider's authorisation
The FCA Register at register.fca.org.uk is the primary check. Search the insurer's name or reference number to confirm authorisation and the activities it is permitted to carry out. Because large groups use several legal entities, match the entity on your policy schedule to the Register entry.
Where cover is arranged through a broker, the broker must also be FCA-authorised; confirm both the broker and the underlying insurer. Companies House at find-and-update.company-information.service.gov.uk provides a cross-check on legal status and filing history.
The Register confirms authorisation but does not tell you about claims handling or service quality. For commercial property, the policy wording, the basis of settlement, and the sum insured matter as much as the insurer's identity, so read the documentation and consider professional reinstatement valuations.
How to compare providers in this category
Start with the sum insured. Commercial buildings are usually insured on a reinstatement basis, so the figure should reflect the full rebuilding cost, including demolition, professional fees, and compliance with current regulations, not the market value. Underinsurance can lead to claims being scaled down.
Check the perils and exclusions, including flood, subsidence, and escape of water, and any conditions for unoccupied premises, which are common in commercial property. Consider whether you need loss of rent or business interruption cover alongside the buildings section.
Verify the insurer and any broker on the FCA Register before placing cover. If a claim is later declined and you disagree, eligible policyholders can refer the complaint to the Financial Ombudsman Service once the insurer's complaints process is complete.
Frequently asked questions
Is commercial building insurance a legal requirement?
It is not generally required by law, but mortgage lenders and commercial leases routinely require buildings insurance to be in place. A lease often specifies who must insure and to what standard.
How should I set the sum insured for a commercial building?
Commercial buildings are usually insured on a reinstatement basis, so the sum insured should reflect the full rebuilding cost, including demolition and professional fees, rather than market value. A professional valuation helps avoid underinsurance.
Do I buy commercial building insurance direct or through a broker?
Both routes exist. Some insurers sell direct, but commercial property is frequently arranged through brokers who can place complex risks. Confirm that any broker and the underlying insurer are FCA-authorised.
What does commercial building insurance cover?
It covers the structure of commercial premises against perils such as fire, flood, storm, and escape of water, usually on a reinstatement basis. Cover for loss of rent or business interruption is often added separately.
How do I verify a commercial building insurer?
Search the insurer on the FCA Register at register.fca.org.uk and match the legal entity to your policy schedule. Cross-check legal status on Companies House. For broker-arranged cover, confirm the broker is also authorised.
What if my commercial building insurance claim is rejected?
Use the insurer's internal complaints process first. If you remain dissatisfied and are eligible, you can refer the complaint to the Financial Ombudsman Service for a free, independent review.
