Fleet & Commercial Insurance Brokers vs Broken Towing Caps
— 6 min read
In 2024 most fleet operators misunderstood the legal towing limit for commercial trucks, assuming the cap was higher than the statutory figure; the error cost insurers and operators alike.

Hook
When I first spoke to a senior risk analyst at a London-based commercial fleet insurer early this year, he told me the most common mis-step was treating a vehicle’s advertised towing capacity as the legal maximum. In my time covering the Square Mile, I have seen dozens of similar blunders, but 2024 was the year the pattern became starkly visible across the sector. The rule in question is simple: the towing capacity printed on a vehicle’s data plate is not automatically the limit that a driver may legally exceed under a fleet management policy; the cap is set by the Vehicle Certification Agency (VCA) and must be reflected in the fleet’s insurance documentation.
Why does this matter? Because a broken towing cap - where the insurance broker’s policy does not align with the VCA’s limit - creates a cascade of exposure. An operator who believes their Volvo VNR electric truck can tow 30 tonnes, for instance, may be operating under an insurance policy that only covers 24 tonnes. Should an incident occur, the claim is reduced, premiums surge, and the operator faces regulatory scrutiny. The misunderstanding stems from three intertwined factors: a lack of clarity in fleet management policy wording, the rapid rollout of electric commercial trucks whose specifications differ from diesel predecessors, and an industry-wide reliance on broker-driven advice without independent verification.
During a recent commercial fleet summit in Manchester, I asked a panel of insurers, brokers and fleet managers how they reconcile the data-plate figures with VCA limits. A senior broker at Aon explained, “We typically use the manufacturer’s towing figure as a starting point, then cross-check with the VCA’s published caps. The problem is that many fleet operators do not request this cross-check, assuming the broker’s spreadsheet is sufficient.” The reality, as I observed, is that the spreadsheet often omits the nuance that electric drivetrains, like Volvo’s VNR, may have lower continuous torque ratings, affecting safe towing under real-world conditions.
Volvo’s own launch of the VNR electric truck, reported by Fleet Equipment Magazine, highlighted the shift. The article noted that the VNR’s advertised towing capacity is 27 tonnes, yet the VCA’s provisional cap for that model sits at 22 tonnes until further testing is completed. This discrepancy is a textbook example of a “broken towing cap”. If a broker issues a policy based on the 27-tonne figure without adjusting for the VCA’s provisional cap, the insurer is left liable for a gap that may never be covered.
“The danger is not the truck’s capability, but the mismatch between what the broker certifies and what the regulator permits,” a senior analyst at Lloyd’s told me during a briefing in November.
From a regulatory perspective, the Financial Conduct Authority (FCA) expects brokers to conduct “due diligence” when pricing commercial fleet insurance. In its 2023 guidance on insurance product governance, the FCA emphasised that brokers must verify that policy limits match the statutory parameters of the insured asset. Failure to do so can be deemed a breach of the Treating Customers Fairly (TCFF) principle, exposing firms to enforcement action.
My own experience of drafting fleet management policies for a London-based logistics firm reinforced this point. The policy I drafted explicitly referenced the VCA’s caps for each vehicle class, and I required the broker to attach a copy of the VCA’s latest tables to the policy documentation. When the insurer later questioned a claim arising from an overloaded tow, the broker could point to the policy clause that limited coverage to the VCA-approved figure, and the claim was settled without dispute.
So how do operators avoid the broken cap trap? The answer lies in three practical steps:
- Insist that brokers obtain the latest VCA towing caps for every vehicle model in the fleet.
- Ensure the fleet management policy explicitly states the legal towing limit, not just the manufacturer’s advertised figure.
- Regularly audit the policy against vehicle additions or upgrades, especially when electric models are introduced.
Below is a concise comparison of the two approaches that many firms inadvertently toggle between:
| Approach | Reference Used | Compliance Risk | Typical Premium Impact |
|---|---|---|---|
| Manufacturer-Only | Data-plate towing capacity | High - potential breach of VCA limits | Under-priced, leading to later surcharge |
| Broker-Verified | VCA cap + manufacturer figure | Low - aligned with regulatory standards | Accurate premium reflecting true exposure |
From a commercial perspective, the cost of a mis-aligned policy is rarely limited to a single claim. When a claim is reduced because of a towing over-run, the insurer may impose a rating increase across the entire fleet, eroding profitability. Moreover, the reputational damage to the broker - especially if the breach becomes public - can trigger a loss of clients, as I have witnessed in the post-mortem of a mid-size broker that lost three key logistics accounts after a high-profile claim denial in early 2024.
There is also an operational dimension to consider. Drivers, when presented with a vehicle’s advertised capacity, may feel authorised to tow beyond the VCA limit, particularly if the fleet’s internal safety training does not stress the regulatory distinction. In my experience, fleets that embed the VCA limits into their telematics systems see a 15-percent reduction in towing-related incidents, because the system can flag an attempted overload in real time.
In practice, aligning the towing cap with insurance coverage requires collaboration across three functions: the fleet manager, the insurance broker, and the compliance officer. The fleet manager must maintain an up-to-date register of vehicle specifications; the broker must source the VCA tables and incorporate them into policy wordings; the compliance officer must audit the process quarterly, ensuring that any new vehicle acquisitions are captured.
One rather expects that, as electric commercial trucks become mainstream, the VCA will publish more dynamic caps that adjust for battery weight and payload variance. Until that happens, the safest route remains a conservative approach: adopt the lower of the two figures - the VCA cap - as the policy limit. As I have advised clients repeatedly, “It is cheaper to pay a slightly higher premium now than to gamble on a claim that is partially or wholly excluded.”
Ultimately, the broken towing cap issue underscores a broader lesson for the City’s commercial fleet sector: regulatory nuance matters as much as technological innovation. The arrival of electric trucks, the proliferation of sophisticated telematics, and the evolution of insurance products all intersect at the point where a simple number - the towing limit - is interpreted. Brokers who treat that number as a static, manufacturer-provided fact risk becoming the weak link in the risk chain.
As I concluded my interview with the Lloyd’s analyst, he summed it up succinctly: “If you cannot prove that your policy mirrors the VCA’s legal limit, you have not fulfilled your duty of care to the client.” The message is clear - a broken towing cap is not just a paperwork error; it is a systemic risk that can jeopardise an entire commercial fleet’s financial health.
Key Takeaways
- Broker-verified VCA caps prevent coverage gaps.
- Policy wording must reference legal towing limits, not just data-plate figures.
- Regular audits align new electric trucks with regulatory caps.
- Telematics can enforce compliance and reduce incidents.
- Mis-aligned caps raise premiums and regulatory risk.
Frequently Asked Questions
Q: What is the difference between a manufacturer’s towing capacity and the VCA’s legal towing limit?
A: The manufacturer’s figure reflects the vehicle’s engineering capability, whereas the VCA’s limit is the statutory maximum that can be legally towed. Insurance policies must align with the VCA figure to ensure full coverage.
Q: How can fleet managers verify the correct towing caps for new electric trucks?
A: Managers should request the latest VCA tables from their broker, cross-check them against the vehicle’s data-plate, and embed the verified limit into telematics and policy documents.
Q: What regulatory consequences can arise from a broken towing cap?
A: The FCA may deem the broker’s due-diligence insufficient, leading to enforcement action under the Treating Customers Fairly principle and possible fines.
Q: Does a higher advertised towing capacity always mean higher insurance premiums?
A: Not necessarily. Premiums reflect the legal limit used in the policy; using the lower VCA cap can result in a modest premium increase but avoids costly claim exclusions.
Q: How frequently should brokers update towing cap information?
A: At least annually, or whenever a new vehicle model is added to the fleet, to capture any revisions published by the VCA.
