You can declare yourself non-resident from the day you left the UK. That should mean you don't have to pay tax on what you send home (though I'm not an expert).
You may still be asked to do a tax return come april, in which case you'll need to tick the box for Split Year Treatment. I recommend TaxCalc software for doing your tax return as it makes it very easy and can actually save you some money (e.g. it offsets UK bank interest tax against your personal allowance - something I wasn't aware of).
I seriously suggest you do a search for non-residency on the hmrc website as it contains lots of information.
