Car Insurance For Modified Cars

What Car Mods Are Covered?

From Subtle To Extreme, Most Mods Are No Problem

We welcome a wide range of modifications, from subtle OEM+ upgrades to fully bespoke builds. Common modifications that we cover include:

  • Engine: remaps, turbo/supercharger kits, engine conversions
  • Chassis: air-ride, coilovers, big brake upgrades
  • Wheels & tyres: aftermarket alloys, various stance-related modifications
  • Bodywork: wide arches, aero kits, wraps, smoothed bays
  • Interior: bucket seats, harnesses, cages, retrims, audio installs

Even if your car’s been heavily modified, chances are we’ll be able to cover it on a like-for-like basis where possible.

We understand how quickly a build can evolve, and our policies are flexible enough to keep pace. Planning to go forced induction next year? Adding a respray or switching wheels for the show season? With Brentacre, cosmetic mods don’t impact your premium, and we don’t penalise you for building your car your way.

Our team personally reviews every quote, which means there are no algorithms, no call centres, just real people who understand the scene.


Get The Right Insurance For Your Modded Car

Talk To Enthusiasts, Not Call Centres

You won’t be passed around a call centre or fobbed off with someone reading from a script. At Brentacre, you’ll speak directly to someone who actually understands modified cars because we own them, build them, and insure them every day.

Whether you drive a mapped Civic, a bagged A3, a retro JDM import, or something no one else has ever built, we get it. Our team knows the difference between coilovers and cut springs, forged pistons and painted rocker covers, and we’ll help make sure every single mod is properly covered.

Already Modifying? Planning To? We’ve Got You Covered

If you’ve just bought a stock car with big plans for the future, start your policy with Brentacre. You can modify throughout the year, knowing you won’t get stung with admin fees or hidden costs for cosmetic changes.

Insurance For Modified Cars

Classic Cars & Modified Vans Welcome

Every build has its own story. From resto-modded icons to repurposed panel vans, we understand what makes your vehicle unique and worth insuring properly. We provide tailored cover that reflects what your vehicle really is, with the same flexible benefits you’ll find in our classic car insurance policies, including agreed value, limited mileage, and like-for-like replacement on declared mods.

If you’ve got a resto-modded Golf, a ’70s Mustang with a heart transplant, or a T5 that’s been reworked into the ultimate self-build campervan, we’ll insure it the right way, not as a generic factory model. And if your pride and joy falls under the banner of a modified van, you’re in exactly the right place.
