i haven't done our house, but have done this at mum's cos i was sure she was well under-insured. she had it at around 60k - when we estimated for basics (not her book collection - lines two walls, or her dvd's) it was up around 135k. her and dad have a LOT of stuff in the shed and i think that's been underestimated too

don't forget if you have antiques then they need to be valued, as well as unique collections. we have one bottle of Bundy that, if i go by ebay sales over the past 2 years, is worth around 900, another over 500. we have two complete sets of limited edition ports - one is valued at over 1000. i know we're JUST insured to cover the basics for now - all that stuff needs to be specially itemised so i've been in contact with the relevant valuers to get help with that so that i can itemise it

if you have a substantial DVD collection, you can put in values in DVD profiler and get an insurance report - i am seriously scared at the value of our DVD's - it's another thing we have to seperately itemise and keep a record of for insurance purposes - the average claim payout for dvd's is only 2k - our collection is worth at least 10 times that!
