Some points drawn from my understand of the legislation and my experience of buying from 17 international vendors since the 1st Jan.
Not sure if maggards lower price every time but if they don't these are the things to consider
If you order the timeless in 4 separate orders (top cap, base plate, handle and stand) and pay for 4 lots of shipping and each consignment is below £135 you won't pay VAT, customs duty or admin fee. You will however pay more in total for all parts compared to a complete razor set (just checked and the same 4 parts of the Ti are $295 as a complete razor and stand or $345 ordered separately. And thats before you take into account 4 lots of shipping opposed to 1 and that you now have 4 packages to pray over so they don't get lost lol.
On the alternative side
If you buy as one order you will save $50 on total cost of razor and stand. But you do pay royal mail 2.5% Customs duty for total cost (goods, postage and insurance) then VAT at 20% drawn from the value of the goods, postage and customs duty as well as the loved royal mail £8 admin fee.
So it all comes down to which will you rather, i've not done the maths as I wasn't sure which razor you were after.
I will also add if you do go for the split order route ensure you talk to maggards ahead of placing the orders so they don't think they're doing you a favour and combine the orders and refund you the shipping lol
