Leak from our bath into downstairs spare room

[concertplayer]

It poured down causing a hole in their ceiling. We had to wait 2 hours for
an emergency plumber and we could not turn off the stopcock.
So just using bowls etc to catch the water.
Plumber says it was due to a crack in the bath wastepipe
and he will fix tomorrow.
Can I claim for this on our buildings insurance?

Yes I believe you can claim for the damage caused by water spillage but not the actual repair if that was someone's fault.

Obviously check what your excess is and consider that your premiums might rise.

Thanks I do not think anyone did it deliberately.
The crack -wear and tear? must have been there for a while
and just got worse.

It sounds like you will need to claim on insurance as your downstairs neighbour will have a claim against you.

Thanks JE678 We are both on the same insurance policy

Plumber states it is our builders who have disconnected the pipe
accidentally (work going on)

If it's the fault of the builders their insurance should cover it.
