Nintendo New 3DS XL [Black/Blue] – £139.75
Nintendo New 3DS XL [Black/Blue] – £139.75 delivered
Australian version, but the hardware is identical to the UK version. You’ll get to get a charger though.
I have imported plenty of stuff from Australia in the past and never been charged any additional fees. Your millage may vary.
Update: You could opt to get it gift wrapped for $4.90 (£2.67), which would in theory remove the risk of getting slammed with import fees.

There is an extra charge for those in the UK which adds 65 Aus dollars to price (~£35) for insurance. I had ordered 2 days ago but received email informing me of this today.
same as above.
Total for XL ~ £175
still worth it???
Where are you guys looking? The websites I’m finding keep saying this item can’t be shipped to the UK
