The cost to insure your block is more expensive than the other block due to the open fire. The cheapest quote we could get is €2285. The cost to insure the other block is €1100.
If your block paid separately the cost per unit would be €285, whereas if the 2 blocks paid together and divided the cost equally, the charge to each unit would be €211.50.
Previously the difference in insuring the blocks was not as much as that, but the open fire issue has only been disclosed recently and has pushed the cost up.
Obviously, the issue now is how the insurance will be paid by each block. It is cheaper for your block by grouping the blocks together and dividing the cost but due to the higher insurance of your block the members of the other block may object.
The practice has been to split the cost evenly and I think that any changes to that practice should be raised at a meeting and put to a vote.
