Thanks Bren.
Well went home at lunch sorted the fuse (i was being a complete woman and forgot i could do trip switch -doh) toilet flushed, shower worked and tap worked. looks like im just going to have to have heating on in the middle of the night. boo to the gas bill eh?
went to shop on way back to work and got some Gin just in case its needed later.
Fingers crossed everything ok :S
