Cheers for the info. Am moving from my rental house back into the mess before I go, so gonna tell Sky there's no way I can continue to be a customer of theirs and that I WILL come back when I get back (someone I've spoken to did that last year and had their contract canxd early without charges).
Have also spoken to Vodafone now, they will refund my rental when I get back on two conditions. 1. The phone is not used when I am away, and 2. I get a letter from work detailing my deployment dates.
Ref the car insurance, I've never actually cancelled car insurance before, so wasn't sure I could just cancel without having to still pay (as it's a contract).
Thankfully the lease on the house is due to end the month I go, which is a bonus because it's a fixed term lease, so if I left one month in they'd be able to make me pay the full six months.
Council tax will be a pittance as I'll be living in, so not too bothered about that.
Thankfully I never got around to getting a TV licence for the house, because I know what those ****s are like with refunds.
Thanks again.
