Thanks BrendanRead this slowly line by line.
I will start with the conclusion just so you do not get confused. You absolutely need buildings insurance.
1) Your house burns down and does not damage anyone else's
Your insurance company will fix the problem.
2) Your house burns down and damages your neighbour's house
You will be liable for the damage done to their house.
Your insurance company will pay for the damage done to their house
3) Your neighbour's house burns down and damages your house
3A) Neither of you have any insurance
You can claim off your neighbour but they probably won't be able to compensate you.
3B) Your neighbour has insurance but you don't.
You can claim off your neigjbour and their insurance company will compensate you
3C) You have insurance but your neighbour doesn't.
Your insurance company will compensate you and may go after your neighbour
3D) You both have insurance.
Your insurance company will compensate you and then discuss the matter with the other insurance company.
In all cases, you are better off with your own insurance.
I'm sorry if I'm upsetting people, that is not my intention. I know that I will be better off with insurance in the event of an accident, etc. I've always had house insurance and understand the importance, but am trying to clarify how it operates.
Would you mind applying you points above to the last two of my original questions, and I'll leave it at that then.
4. Unforeseen events; e.g. say in a storm a tile or slate fell my house on landed on a neighbour's car?
5. Conversely to No. 4 above; if the neighbour's aerial fell over and damaged the shared chimney (I don't have an aerial) or my roof, would they be liable for repairs or because it is a shared chimney we would both have to pay for repairs even though it's their aerial?
These events haven't happened, but I'm particularly interested in the aerial on chimney situation. I live in an area where high TV aerials are required, I don't have an aerial on our shared chimney, but my neighbour does. I have no problem with that, but these aerials are heavier than we often think and when a storm is blowing move quite a lot. I haven't heard of this happening, but I could imagine a chimney at least being cracked if not further damaged. It's our shared chimney, but the neighbour's aerial. How would insurance handle it?
Thanks
