OK, ask yourself this - when was the last time you heard about a gas leak in your street, in your neighbourhood? town? Indeed can you remember it ever happening?
The fact is that statistically there is avery low probability of it happening, which is why the premium is so low (though not as low as it could be - utilities make millions from these policies. Ditto water.
Electricity? well the cabling to your meter box is the utilities to sort out anyway, so there is really no point in having cover for that (if that is what it is).
Now, if I lived in a really old house and in an area known for subsidence or heave, I might just think �60 pa was worth it. Otherwise, no way.
