You have to be careful how you do that as it can be a pain to lose the UK tax residency even if you live in another country.
I know, i'm reading all about it. I know it's 5 years out of the UK....but the way I look at it I could spend 5 years traveling, come back, sell my stuff as a tax resident of another country and still be in a better position that paying another 25% on the tax.
You can still be in the UK up to 180 days a year or so.
