I wonder if refusal by some insurers to cover the pedal box is due to other risk factors when considered in conjunction with the pedal box? Maybe a ‘young’ driver with pedal box = refuse to provide cover and more ‘mature’ driver = OK to cover. Just a thought.....
Also, bear in mind that some insurer’s may have a range of car insurance products, ranging from a ‘low cost’, no-frills policy where only ‘standard’ changes can be made (often with the customer making the change themselves on a self service basis via a web portal) to a more flexible product supported by a large call centre operation and a team of underwriters. The no frills product will be cheaper to buy than the more flexible one as the insurer’s operating costs are lower so will be popular with the costumer, but the downside is that it will be more restrictive in terms of the changes that can be made. These basic, no frills products might not allow vehicle modifications.
Could be the reason why an insurer adopts a different approach to different customers with pedal boxes; happy to cover those who have the ‘flexible’ product but not those with the no-frills product?
