So..I have a 2 bed upstairs flat as part of a house conversion. Subsidence started a few years ago. Managing agent and insurance company are fannying about. Tenants moved out after about a year as claim wasn't moving forward very fast. I had reduced their rent as there were some cracks. There is some water ingress now so I don't feel it's right to rent it out. Insurance are charging £2.5k (split between 3 flats for buildings only, excluding subsidence. As my flat has now been empty for more than 12 months, my cover is limited to FLEA only, so of pretty much no value. As much of the delay has been down to the insurers, can I contest this? I feel like everyone else is fannying about and I'm suffering the cost.
