You must tell your car insurance company about heath changes such as Parkinson's.
It is a criminal offence to make a false statement or to withhold information to get motor insurance and it may also make your policy invalid.
Renewing or switching car insurance
Some car insurance companies may add extra premiums for people who have disabilities or medical conditions, including Parkinson's.
Shop around for the most competitive cover and get a number of quotes.
It is also very important to check the policy thoroughly and to read the small print before you sign anything.
The British Insurance Broker's Association can help you find companies willing to quote for drivers with Parkinson's.
If you have a complaint about a car insurance company, the Financial Services Ombudsman may be able to help you.
The ombudsman is an independent and impartial organisation set up to sort out complaints that consumers and businesses are unable to resolve themselves.
It is important that you try to resolve your problem with your insurance company before contacting the ombudsman.
