Received a letter offering Plumbing & Drainage Plus for 75p a month for 12 months £9 total no excess.
Looking at the url doesn't look like its specific to my address so other people might be able to us it.
Might not cover everything but for £9 and no excess not a bad piece of cover for just in case.
Whenever I have used them they have always been good and cancelling after 12 months is easy enough.
Hope it helps someone
