Rights question, rented flat is water damaged by flat above

[gavgavgav]

A friend of mine owns a flat that he leases out, there are 2 flats in the building and the owner above (flat also leased out) owns the freehold with my friend having the leasehold of his flat. There is 'landlords' building insurance for both flats existing that my friend is looking into what that would cover. He does not have specific landlords insurance in addition to this.

The flat above had a leaking boiler which has damaged the flat below, what you would expect being the ceiling, wall, carpets (maybe floor). The may be damage to a futon from the Tennant too.

The tenants notified my friend there was water coming in, my friend notified the flat owner above & he has said the leak has now been fixed.

The problem is that he is not taking responsibility for the damage caused. His claim is that the tenants of my friends flat should of notified that the leak was there earlier.

The citizens advice was not very helpful. Is there a useful statement somewhere that we can use to help encourage the landlord above to take responsibility?

Thanks for the responses so far, my friend has read them all. Looks like it is one of those situations where what feels to be the 'right thing' in our society doesn't match the legal association of responsibility.

Luckily for my friend is that the damage is quite minimal.

Upside is he may join pistonheads now!
