Ok, here goes then, hopefully this may be helpful to someone else!

With 4 weeks to go, this is what I've done already -

Water - final bill requested based on estimate of what we'll use before we go
electric - can't get final bill until meter readings on the last day but can then pay the final bill over the phone by card and close account,
council tax - - advised of date moving out of property closed account
tv licence - can't be done until 2 weeks before you go
Contents insurance - changed policy to a rented property policy and replaced existing policy
life insurance - (relating to mortgage) called for advice on whether i would still be covered for life or critical illness cover if I live abroad (basically yes but the critical illness is not 100% guarantedd to pay out, only on a case by case basis)
Tesco club card - changed address to my mums
mobile phone -changed account to pay as you go cancelled monthly contract
inland revenue - printed off P85 forms and trying to make sense of them!
contact lenses - had a check up and ordered 9 months worth so I won't run out anytime soon
mortgage - asked for statements to be sent to mums address

erm...i think thats about it. Apart from putting everything we own on ebay which is stressful in itself! we have aslo packed up all books, dvd, photo album to go in my mums loft, and have sorted clothes inot piles of taking, maybe taking and not taking.

apart from my house looking like a jumble sale, I think we're doing OK! if anyone has any other advise or anything I've forgotten please let me know!
thanks
