### Car Insurance Warnings as Drivers Risk Policies by Asking Friends for Petrol Money

Motorists in the UK are being cautioned about the risks of accepting money for petrol from friends, with experts warning that such actions—if not carried out carefully—could lead to their car insurance policies being invalidated.

The warning centres on the fine line between recouping the genuine costs of a journey and making a profit from carrying passengers. While sharing the expenses of a trip with friends may appear innocuous, experts advise that overcharging, even by a few pounds, could have far-reaching consequences.

Alicia Hempsted, a car insurance specialist at MoneySuperMarket, has raised concerns over the practice, explaining that while cost-sharing for fuel is permitted, charging more than what the trip actually costs can land drivers in hot water. “At first glance, asking for a tenner when the petrol only cost a fiver might seem harmless,” Hempsted says. “However, from an insurer’s perspective, this could amount to making a profit. Just a small surplus can shift you into territory known as ‘hire and reward’—essentially meaning you’re operating as an informal taxi service, which standard insurance does not cover.”
She warns that in the unfortunate event of an accident while such arrangements are in place, insurers may not only reject any claims, but could also cancel the insurance cover entirely. The ramifications, she points out, are serious, potentially including heavy fines and prosecution for uninsured driving.
The Association of British Insurers and HM Revenue and Customs both permit genuine, non-profit cost-sharing amongst friends or colleagues, but they are clear: any form of profit-making, however trivial it might seem, can constitute a breach of policy terms. This places the driver at risk of being categorised as conducting a commercial activity, which usually requires specialist ‘hire and reward’ insurance.
Further complicating the matter, behaviours such as regularly offering lifts in exchange for money, consistently charging above the real cost of fuel and wear, or even advertising lift services online could be deemed evidence of running a commercial operation. Should an accident occur under any of these circumstances, insurance firms may choose to void the cover from the outset, effectively treating the policy as if it never existed. Claims for damages, injury, or loss would be denied, and the incident could even be reported to the authorities.
“Drivers sometimes overlook how seemingly minor actions can have major implications,” Hempsted notes. “Being uninsured means out-of-pocket costs, possible endorsement points on your licence, or even facing prosecution. It’s not just about a denied insurance claim—it’s about the legal consequences too.”
When it comes to staying within the rules, Hempsted recommends that drivers strictly limit any reimbursement requests to actual journey costs, including both fuel and reasonable wear and tear. A practical way to gauge this is by using prevailing HMRC mileage rates—which at present stand at 45p per mile. This figure is designed to cover not only petrol but also broader running costs such as maintenance and tyre wear.
She further advises drivers to thoroughly check the terms of their insurance policies, as provisions around lift sharing can differ considerably between providers. Some policies contain explicit clauses outlining what is allowed and what is not, so understanding these details is crucial for all motorists.
Those considering using their car for any sort of regular income—such as ride-hailing for companies like Uber, or making deliveries—are emphatically advised to seek out appropriate business or ‘hire and reward’ cover. “Don’t take chances. Compare quotes and ensure the insurance you have matches the way you use your vehicle,” says Hempsted.
As road users across the UK seek ways to mitigate motoring costs, the temptation to recoup a bit extra from friendly lift-sharing arrangements is ever-present. Nevertheless, experts stress the importance of transparency and caution, noting that a few pounds gained in petrol money is simply not worth the prospect of being left uninsured and potentially facing legal action.
Motorists are encouraged to remain vigilant and informed, ensuring that their efforts to save money do not end up leading to much greater losses.
