You may be able to lower your premium, yes. Firstly, be careful when it comes to modifications. If a more powerful engine has been added, the insurance provider may take this as a risk that you’ll drive faster and have an accident. So, in that case, it’s likely your insurance premium will be high. Insurance providers also think that modified cars look better and catch the attention of thieves, who might steal the car, or vandals, who might damage it.
Some modifications are seen as beneficial, however. For example, putting in a car immobiliser, a tracking system or an alarm. These help to prevent your vehicle from being stolen and could lower your insurance premium. However, you may need to speak directly with your insurance provider to see these reductions reflected in your premium.
Another way to possibly reduce the cost of your premium is to avoid any unnecessary add-ons and to pay the full cost of your car insurance upfront.
