Are you allowed to modify a financed car?

In most cases, you aren’t the full owner of the vehicle, and won’t be allowed to modify the car. Some lenders may allow customers to modify the vehicle, but you need to get their consent first. It depends on your agreement, so check your contract or contact your lender if you are unsure.

It’s important to take your time when thinking of buying a new car. It can be a very exciting time but make sure you thoroughly check the car to ensure it has everything you need. For more information please see our guide which describes the checks you should make when buying a car.

Can you modify a car financed through a personal loan?

Unlike car finance agreements such as HP, PCP, CS or PCH, personal loans aren’t usually tied to the vehicle itself. This means that you paid for the vehicle in full and are the legal owner. This means you can modify the vehicle how you are like. Make sure any modifications are done safely and legally, and don’t invalidate your insurance or make it more expensive.

We’ve written a guide that explains the differences between car finance and a personal loan, so you can understand them better and make an informed decision.

What does it mean to modify your car?

Modifying a car is when you make a change to a car that makes it different from the manufacturer’s original specifications. Modifications can change the appearance or performance of the vehicle.

Some common modifications include:

  • Cosmetic changes: Changing the colour, installing new wheels, diffusers, spoilers, window tints, light upgrades, and adding body kits.
  • Performance upgrades: This includes even slight adjustments to the engine, suspension, gearbox, brakes, exhausts, etc.
  • Equipment upgrades: Adding a tow bar, upgrading the battery, changing the sound system, installing custom seats.
  • Entertainment changes: Upgrading the stereo or changing the infotainment system.

This is not an exhaustive list, so it’s essential to check with your car finance company to understand if you’re allowed to make any changes – even the smallest part or detail might be considered a modification.

This doesn’t mean you can’t replace parts if you need to get the car serviced. Changing tires, the oil filter, and small things like this are fine. Nor does it mean you can’t add seat covers or a phone holder to the car. Something like replacing a battery is usually ok but changing it to a different spec could be classed as a modification.

What if the modifications increase the car's value?

Modifying your car may seem like a win-win situation if the changes increase its value, but it’s not that straightforward. Modifications do not always have good resale value.

Upgrades to the performance or appearance may enhance the car. But the finance company will have trouble determining the new value of the modified car. Modifications that are not easily reversed, such as a rear spoiler or custom paintwork, may decrease the car’s value compared to its original factory appearance.

Most lenders simply won’t allow any vehicle modifications until you own the vehicle, even if the modifications increase the value.

What happens if I modify a financed car?

Most modifications to a vehicle can be reversed, including engine and performance changes. However, the ability to modify a car while under a finance agreement depends on the finance company’s policies. They often view temporary modifications as permanent because they can affect the car’s value.

Modifying a financed car without the lender’s approval can put you in a difficult position. The finance company may terminate the agreement and give you a deadline to pay off the finance in full. Depending on the type of modification(s), you may be charged according to your contract.

The best thing to do is to check with your lender before making any changes to your car.

Why you should always check your finance agreement

As with all significant financial commitments, it’s essential to review the finance contract thoroughly. If the contract states that you cannot modify the car, there probably won’t be much flexibility.

If you have specific modifications in mind, such as installing towing equipment, speak with the car finance company. This way, you’ll receive clear answers and avoid any confusion.
