Hot water cylinder leaking

[n111ck]

Came home to find water leaking through living room ceiling - turned out to be from hot water cylinder.

Does anyone know if a knackered cylinder:

- would be covered by nhbc as home is less than 10 years old
- cylinder would be covered by any sort of warranty
- home insurance would cover replacement?

Will be ringing round tomorrow to get definitive answers but anyone's experience would be useful.

Not had much luck with the warranty as there is no evidence that it has been serviced annually.

However it may not be a leak - plumber thinks that thermostat got stuck on and the water was condensation from the tank overheating. This would run down the inside of the tank and come out of the hole for one of the pipes.

Have switched it back on and checked the water is normal hot temp but there is new condensation under the lid where the expansion vessel is - would that be normal?
