Most of us know that if you want to drive on British roads, you’re legally required to have adequate insurance for your vehicle.

The best kind of insurance policy is one you never have to use, but in the unfortunate event that you find yourself in need of assistance from your provider, you may fall foul of some easy-to-miss details that could leave your policy invalidated – and your wallet facing a hefty hit.

The first major pitfall is often covered in headlines, yet plenty of drivers still breach it every year. Known as “fronting”, this infringement is where a low-risk driver, like a parent, is listed on an insurance policy as the primary driver, when in fact they aren’t.

It might be tempting to put someone else as the primary driver as a way to reduce insurance premiums, but it’s actually a type of fraud – and therefore a criminal offence – to do this. Not only will you invalidate your insurance policy, but you also risk getting six points on your licence, an unlimited fine, a possible ban from driving and even a criminal record and prison time.

In fact, providing any false information – regardless of how innocuous it might seem – could result in an invalidated policy. Most of us know that you should inform your provider when you change address (as premiums are partly calculated based on your location), but you also need to tell them if you change jobs. This is especially important if the change has an impact on your usual driving habits, as longer or more frequent commutes could increase your risk.

It’s not just your personal information you need to be honest about – you also need to be transparent about how you use your car. If you’ve ever considered moonlighting as a delivery driver or offering paid-for ride sharing services, you’ll most likely need to have a specialised insurance, which may differ from your everyday policy.

What’s more, if you’re pulled over by police making deliveries on the wrong kind of insurance, you can face up to six penalty points on your licence as well as up to £300 in fines.

Aside from the risks of delivering burgers, pizzas or people around your area, you might also invalidate your insurance by travelling with friends and family – specifically, too many of them. Overloading your vehicle – whether it’s with people or possessions – and exceeding the recommended weight or passenger limit could result in mechanical issues and your insurance policy being invalidated in the event that you need to make a claim.

It’s also important to check the weather before you set out on the roads, as ignoring official advice and driving in certain weather conditions could be viewed as negligence, resulting in your policy being invalidated. This rule is more in relation to the Met Office’s rare red weather warnings, the last of which was issued in July 2022, during a heatwave that saw some road surfaces melt as the government declared a “national emergency”. Choosing to ignore these warnings could see your insurer viewing you as knowingly putting yourself and others at risk, meaning that if you have an accident, they are unlikely to provide cover for it.

Regtransfers‘ CEO Mark Trimbee said: “It’s important to take care when setting up your insurance policy – making sure you get the right cover, and that all your information is correct and up-to-date, can be the difference between peace of mind and a potential nightmare.

“If you’re ever unsure about what your policy covers, check your documentation or insurer’s website to read up on the finer details. Above all else, drive responsibly and consider whether your actions, as a motorist, could be considered “careless”. Always err on the side of caution to avoid a nasty shock!”

Finally, Regtransfers recently revealed that almost half (46%) of all vehicle thefts in the UK last year occurred as a result of the doors being left unlocked. If the stress of having your car stolen wasn’t enough, this could also be another way for your insurance policy to become invalid.

“It should become a habitual behaviour to lock up your car, even if you’re just refuelling or parking briefly in your driveway.. Youu should never leave your vehicle running if you’re leaving the driver’s seat, and keep an eye out to make sure all windows and sunroofs are fully closed.”
