I live in Northern Ireland, how will Brexit affect my car insurance?

There’s no impact on your car insurance. Your normal cover details (as set out in your Insurance Document wording) apply.

An agreement has been reached (the Withdrawal Agreement), which means that previous arrangements remain applicable until 31st December 2020.  Therefore, there is no need to provide any special documents (such as a Green Card) as proof of insurance when driving outside of the UK.
