We’ve got a water leak from (we believe) our mains pipe under the kitchen. They can’t start the work to access & identify the cause (& therefore insurance accept liability) until we move out. My question is this - on what basis ‘could’ insurance reject the claim? They seem to refer to gradual damage, but I don’t see how we could have known about it, so that seems unfair? Also we changed insurers in May, could they go back & try & push on to the previous insurers, or does that not happen? Any advice from knowledgable people in this field, gratefully received! Thanks
