But if the company or person were to "accidentally" mark the customs form "gift" then you wouldn't get charged anything.
If the rules are properly applied, and the sender shows up as a company, it won't qualify as a gift since the sender MUST be a private individual. There's a raft of other rules the "gift" must qualify for as well. You might be lucky and have it go thorugh anyway, but it's is luck if it does.
David _b, there's no easy way to be sure of the actual cost in advance. The general rule (unless excise duty is also involved, like on booze, tobacco, etc) is that you add up the cost of goods, postage, insurance, etc, and then apply a duty rate to that total according to the commodity code the goods fall into .... and there's tens of thousands of commodity codes, with rates from 0% to >70%.
Then, having worked that out, you add VAT (on most items) at 17.5% on that previous total (including the import duty, so yes, you pay VAT on mport duty).
Then, in all likelihood, you pay a flat charge (£10-£20 typically) for "handling".
It is certainly true that many goods get charged duty at 3.5% because, for many low value postal gifts that's a flat rate applied instead of the commodity code rate. In which case, duty and VAT will amount to about 22% and probably that flat charge on top of that. So a decent guess would be 22% plus £15.
But you'll only know for sure when the goods arrive .... with the Customs bill.
