What commercial insurance actually is

Commercial insurance is an umbrella term rather than a single product. It covers every insurance a UK business might buy to protect its assets, its people, its earnings, its liabilities to others, and its exposure to specific risks arising from what it does. A sole trader running a mobile plumbing van and a mid-market manufacturer with a hundred employees both buy commercial insurance, but the composition of that programme looks nothing alike. The point of a specialist broker is to work out which parts of the umbrella the business genuinely needs, which parts are legally required, and which parts are worth paying for on a risk-transfer basis rather than absorbing on the balance sheet.

At its widest, commercial insurance covers property (buildings, contents, stock, computers, business machinery), liability (public liability, employers' liability, product liability, professional indemnity, directors' and officers'), fleet and commercial motor, cyber and data, business interruption, goods in transit, engineering and inspection, credit, legal expenses, and a long tail of specialty covers such as terrorism, environmental impairment, crime and fidelity, kidnap and ransom, contract works, and event cancellation. Any UK SME will typically hold three to seven of these lines at any given time, packaged either as a bespoke commercial combined policy or as a set of standalone contracts placed with different insurers.

The UK market for commercial insurance is served by a mix of direct insurers, aggregators, generalist brokers, specialist wholesale brokers, and Lloyd's syndicates. Regulation sits with the Financial Conduct Authority under the Insurance Distribution Directive (IDD), ICOBS, and — since 2015 — the Insurance Act, which imposes a duty of fair presentation on commercial buyers. That duty matters. Commercial policyholders have a positive obligation to disclose every material circumstance that a prudent insurer would want to know, and failure to do so can leave a claim unpaid or a policy voided. A broker's core job on a commercial placement is to help the client discharge that duty properly.

Buying commercial insurance well is not about finding the lowest premium. It is about matching the policy wording to the risk, testing exclusions and warranties against the way the business actually operates, and building a claims record with insurers who will still be there in three, five and ten years. That is a long-cycle relationship, not a one-off transaction, which is why a named-broker approach — the same person from first call to bind, and through any claim that follows — tends to serve professions and small commercial buyers better than a call-centre model.

The nine core commercial covers

The nine covers below account for the majority of what UK SMEs actually buy. Not every business needs all nine, and some businesses need cover beyond this list — product liability, professional indemnity, directors' and officers', engineering inspection, specie, cargo, terrorism, environmental impairment, cyber crime, kidnap and ransom. What follows is the working core: what each cover does, who it is for, and the sums insured that tend to sit under a typical UK SME schedule. Anything more complex is normally placed on top of this core as a specialty line.

Commercial property insurance

Covers the physical fabric of a business — buildings owned or leased, tenants' improvements, contents, stock, plant and machinery — against perils such as fire, storm, flood, theft, malicious damage, escape of water, subsidence and impact. Sums insured are set on a reinstatement (rebuilding) basis for buildings and a replacement-as-new basis for most contents. Typical UK SME limits run from £250,000 for a small office through several million for a mid-sized industrial unit. Commercial property is usually written on an all-risks or specified-perils basis, and the wording gates matter as much as the headline sum insured — average clauses, unoccupancy conditions, alarm warranties and business-hours restrictions all shape what you actually recover after a loss.

Public liability insurance

Covers legal liability to third parties — customers, visitors, members of the public, other contractors — for injury or property damage arising from the business's activities. It is not compulsory by statute for most businesses, but it is required by many contracts, landlords and public-sector procurement frameworks. Standard limits are £1m, £2m, £5m and £10m; the trade and the contracts the client bids for tend to dictate which limit is appropriate. Public liability sits alongside product liability (defects in goods sold) and, for professional services, professional indemnity (financial loss from advice or design).

Employers' liability insurance

Employers' liability is compulsory for almost every UK employer under the Employers' Liability (Compulsory Insurance) Act 1969, with a statutory minimum indemnity limit of £5m. In practice, most policies are written at £10m to cover multi-claim events. The cover responds to injury or disease sustained by employees in the course of their employment, and applies whether the employee is permanent, part-time, casual, or a labour-only sub-contractor treated as an employee for insurance purposes. Certificates must be displayed and made available to HSE inspectors, and every certificate is kept for at least 40 years to support long-tail industrial disease claims.

Commercial vehicle and fleet insurance

Covers vans, HGVs, plant, and any vehicle used for business purposes. Compulsory under the Road Traffic Act 1988 at the third-party minimum, but almost always bought at comprehensive level for vehicles carrying tools, stock or client property. Sole-trader van policies sit alongside fleet policies (typically five vehicles and up) which are rated on the fleet's claims experience rather than each individual driver. Tools-in-transit and hire-in-plant extensions matter for trades; goods-in-transit cover applies where cargo belongs to a client.

Cyber insurance

Cyber insurance covers first-party loss (business interruption from a network outage, ransomware payments where lawful, forensic investigation, incident response, data recovery, notification costs) and third-party liability (claims from customers or partners after a data breach, ICO regulatory response costs, PCI fines to the extent insurable). It has moved from a niche product to a boardroom staple since GDPR and the ransomware wave of the early 2020s. Typical SME limits are £500,000 to £2m; mid-market buyers commonly place £5m or £10m towers with layered capacity.

Shop insurance

A packaged commercial combined policy designed for retail premises — buildings, contents, stock, business interruption, money, PL and EL bundled together with a shop-specific rating base. Suitable for independent retailers, convenience stores, boutiques, gift shops, and small chains. Stock is usually rated on a declared peak-stock basis to handle Christmas and seasonal build-up, and glass cover is included by default. High-value stock (jewellery, electronics, alcohol, tobacco) sits under specific warranties around storage, alarms and out-of-hours security.

Restaurant insurance

A hospitality-specific combined product covering the building or leasehold interest, contents, stock (including chilled and frozen), commercial catering equipment, deterioration of stock following freezer failure, business interruption after fire or flood, employers' and public liability, and — importantly — food poisoning and defective workmanship extensions on the liability section. Rating factors include cuisine type, opening hours, entertainment (live music, dance floors), delivery activity, and whether the premises hold a late-hours licence.

Landlord insurance

Buildings insurance for property let to tenants, with landlord-specific extensions — loss of rent, alternative accommodation, malicious damage by tenants, property owners' liability, legal expenses for possession proceedings. Residential landlord policies range from single properties to portfolios of hundreds of units. Commercial landlord policies cover offices, industrial units, retail parks and mixed-use buildings, usually with a schedule listing each property and its own sum insured. Buildings sums insured need periodic reinstatement cost assessments to keep pace with construction inflation.

Business insurance (commercial combined)

A packaged product covering the standard needs of an SME — property, contents, business interruption, PL, EL, portable equipment, personal accident, money — under a single schedule with one renewal date and one premium instalment plan. Suitable for offices, professional practices, consultancies and light-industrial businesses where the risk profile is well understood. Larger or more complex risks tend to be placed on a bespoke commercial combined basis with individually negotiated wordings rather than a packaged product.

Trades insurance — a subset of commercial with specific needs

Trades insurance sits inside the commercial umbrella but the buying pattern differs. A trades business — electrician, plumber, builder, joiner, roofer, decorator, landscaper, gas or heating engineer, general contractor — typically needs public liability, employers' liability if they have staff or labour-only sub-contractors, tools cover, hired-in plant, a commercial vehicle policy, and often contract works cover for jobs that involve materials on site over multiple days. The exposures are different in kind from a purely office-based business: tools and stock travel with the trade, works are exposed to weather and theft, and liability arises from craft as well as premises.

Contract works cover — sometimes called contractors' all-risks — insures the works being carried out for the client against damage before handover. It matters most on jobs where materials are on site for weeks or months, or where a partially completed structure is exposed to storm, fire or theft. The distinction between the trades business's own tools (tools cover), plant hired in from a plant hire company (hired-in plant), and the client's works (contract works) is a source of frequent claims disputes, and getting the demarcation right in the schedule saves arguments later.

For trades in the South West, Apex has a local footprint page covering the ten most common commercial trades across twenty-two cities and towns. Those pages are indexed further down.

Trades buyers should also be aware that the JCT and NEC family of construction contracts require insurance in the joint names of employer and contractor, with contractors' all-risks cover for the works and specific indemnity limits for PL and product liability. Where a client is bidding for JCT-form work, the policy needs to be verified against the contract's insurance schedule before quoting the job. Getting a certificate wrong at pre-contract stage is one of the more common reasons a job stalls at signature.

How Apex approaches commercial placements

Apex Insurance Brokers Limited is a Bristol-based independent brokerage, directly authorised by the Financial Conduct Authority (firm reference number 724952) and established in 2009. Client retention across the book runs at 95%. The approach on every commercial placement follows the same sequence, whether the client is a two-person consultancy or a mid-market employer.

Submission preparation. A commercial submission is the document set that goes to insurers before terms are quoted — proposal form, statement of fact, supporting risk information, claims experience, contract wordings where relevant. Getting this right is the single biggest lever on the terms a client will be offered. Apex spends real time with the client at this stage: walking through the questions properly, testing the answers against how the business actually runs, and building the narrative around unusual features rather than letting them surface later as a decline or a rating loading. The Insurance Act 2015 duty of fair presentation is discharged at this stage or not at all.

Market access. Apex has direct terms of business agreements with over thirty UK commercial insurers, and reaches Lloyd's syndicates via wholesale broker relationships for risks that need specialist capacity — professions PI, cyber, D&O, environmental, event cancellation, contingent business interruption. The market is chosen to fit the risk, not the other way around. Where a client's risk profile suggests a particular insurer's appetite, the submission goes there first; where the risk is unusual, a controlled market panel takes it out to two or three insurers who have written similar risks before.

Wording review. Every quotation is read against the client's actual exposures before it is presented. This is where the specialist broker earns their keep: identifying warranties that a client cannot realistically comply with, exclusions that would bite on the client's core activity, and conditions precedent that shift the burden of proof at claim. Where a wording gap matters, the broker negotiates an amendment or moves the placement to a market that will offer better terms.

Reinstatement and sum-insured discipline. The single most common cause of underpaid property claims in the UK is under-insurance triggering an average clause. Buildings sums insured drift out of date as construction costs rise; contents values fall behind stock inflation; business-interruption indemnity periods are set too short for the realistic time to reinstate. On every new placement and every renewal Apex tests the sums insured against a rebuilding cost estimator, the client's own asset schedule, and a plausible worst-case downtime. The finding is often that a client is over-buying on stock and under-buying on buildings; either way, the schedule ends up matching the exposure rather than a five-year-old estimate.

Named broker throughout. The client's account is handled by one named person from first call to bind and through the life of the policy. When a claim happens, or a mid-term adjustment is needed, or a certificate is required for a new contract, the same broker handles it. That model is the reason Apex retains 95% of clients year-on-year — the relationship compounds.

Claims advocacy. When a claim happens, Apex represents the client to the insurer, not the other way around. That means preparing the claim notification with the client, testing the insurer's response against the policy wording, and pushing back where a decline or a reservation of rights is not supported by the contract. On disputed claims Apex will instruct policyholder-side loss adjusters, coverage counsel or a claims consultant on the client's behalf. For most SME claims — property, business interruption, PL, motor — the notification-to-payment cycle is straightforward and the broker's role is administrative; on the small proportion that go wrong, the broker's role is decisive.

Renewal review. Every renewal is treated as a fresh placement, not a rollover. Sums insured are checked against current reinstatement costs, exposures are re-tested, claims are reviewed, and the market position is validated. Where an insurer's appetite has changed or a wording has moved against the client, the broker re-shops the risk. Retention is high because the review is real, not because clients are locked in.
