Buying your first home can affect your car insurance because changing your garaging address, parking arrangements or daily driving distance may change the insurer’s assessment. Tell your insurer before moving and check that your policy covers the new address, especially if the car will be parked in a driveway, garage or on the street. Some insurers may offer a multi-policy discount when you insure your home and car together, but this is not guaranteed and should be compared with separate quotes. Ask the insurer how the change affects your premium, excess and cover.
