Failing to declare modifications could invalidate your coverage, leaving you liable for costs in the event of an accident or theft.
Different insurance companies have varying thresholds for what they consider a “significant” modification. Some insurers might allow mild cosmetic changes without increasing your premiums, while others will raise rates for even minor tweaks. Always check your specific policy and ask clarifying questions to avoid misunderstandings. Being transparent and proactive with your insurer ensures you remain protected and clarifies any potential impact on your premium.
