Property insurance covers the building itself against natural damage as well as causes such as vandalism and falling aircraft!
Cover for accidents to fixed glass and ceramics (bath, toilet, windows etc) are usually covered on standard policies but can be extended to all parts of the house for an extra cost, e.g. damage caused to the ceiling when you fall through it from the loft.
mortgage2move can advise on the differences between policies, compare prices from more than just one company, arrange cover and aim to ensure that a certificate of cover is sent to your legal advisers to enable exchange of contracts to take place on time.
