If you’ve modified your car, chances are you’ve spent money and time on making it the vehicle you want. We offer agreed value policies to cover the car and its modifications. This ensures that even if you have to rebuild the car from scratch, you don’t get paid for less than the true value of the vehicle.

Is modified car insurance more affordable?
Yes, when compared to non-modified cars that offer like-for-like performance, modified car insurance can be cheaper. There are a number of discounts available to modified car owners, including for limited mileage cover, modifications you’ve done yourself, and for owners club members. Compared to similar non-modified performance vehicles, most custom cars are also treated as classics so premiums reflect this.

Cover for young drivers
Insurance is already expensive for young drivers, but pair this with a modified car and you’ll be paying through the roof. Thankfully, we view you a little differently. We understand that passion for cars begins early, which is why we insure people that other insurance brokers deem “uninsurable”.
Cover for adapted vehicles and WAVs
And if you’re a disabled driver? We also cover you if you have a disability and need to modify your car so it’s more usable. Disabled adaptions can be covered on a new for old policy – ask us about new for old cover on disability adaptions. We also offer cover for wheelchair accessible vehicles (WAVs).
Should I tell my insurance provider my car is modified?
Yes, modifications can void your insurance policy if not declared, which is why we offer dedicated insurance specifically for modified cars. Even if you don’t think a modification matters, it’s best to let us know when you’ve made a change to your vehicle. This way, we can alter your policy in line with your needs and make sure anything disclosed is covered.
Can I get modified classic car insurance?
Whether you’ve restored your classic to its former glory or you’ve modified your vintage car, we can cover it. We offer modified classic car insurance to petrolheads who have gone a step further to make their classic vehicle their own.
