Yes you will have to pay import duty. As the import duty is calculated on the item cost INCLUDING shipping and insurance, added to Evikes horrific shipping costs you WILL pay a lot of it too.
Evike are okay. They know about UKARA and will even 2 tone if necessary. Delivery is not fast but is reasonable and you get tracking numbers. Expect to pay an additional 20% tax plus £8 handling charge.
Tax is 20% but that's on top of import duty as well which will depend on what you're bringing in. £8 seems low for a handling fee. If Royal Mail get involved it'll be more like £13, if it's UPS then it could be more.
