Hoping for some advice, We have recently had our basement converted into proper living space. Part of the work included underpinning along the front of the house and half of one side due to the foundations not being deep enough. There hasn't been a history of subsidence or stuctural issues previous, just normal settlement. We thought we'd do the right thing and let our insurance provider (M&S) know and they have said they won't cover the house because it has been underpinned and have now cancelled our insurance (21 days notice). I have now spoken to Tesco to get a quote and they asked the question about cancelled insurance. Once again I did what I thought was right and mentioned the issue with M&S. They have said they won't even consider giving us due to the cancelled insurance. Not sure what to do next and hoping for some advice? Thanks, Kyle
