    Car modification laws in the UK and elsewhere are in place to ensure drivers who want to enhance their vehicles adhere to certain safety standards. While modifications are a great way to alter the look and performance of a car, some may also affect the handling and overall safety of the vehicle on the road.

    You may need to inform your insurance company of any modifications made to your car – whether they were already installed when you purchased the vehicle or if you have done them yourself. If you don’t tell your insurer, any future claim you make could be turned down. Worse still, your insurance could be completely invalidated. Modifications carried out to any car may affect the vehicle manufacturers warranty.
