OK. So we rent out the house my husband had before we got married. Yesterday we got a letter from the neighbour via the estate agent that manage it for us. It said she wanted to have a log burner and chimney needs upgrading. We don't have any fires in our property so don't require a chimney, it's not causing a leak or in a state where it's likely to fall over. The quote said £1500 plus scaffolding of unknown cost and states the neighbours are splitting 50:50.
Being this is the first we've heard of it and it's functional for our needs at the moment do you think it's fair for us to pay half because she now wants a log burner?
