before i phone up and sound like a tit

moving out of my flat for a month till the new ones least starts

Moving to my parents for a month who have their own crap policy for contents.

Can i move my contents insurance with me to my parents as it covers my bikes and for accidental damage and theft away from home.

Yes, your premium may alter if parents house is a bigger/lesser risk. Be aware as well that in the event of a claim, two companies would try and split the risk/payout.

Very much dependent upon the insurance policy I would say.

Best to phone them up and discuss.
