They do seem to be adding something extra into the price, maybe it's to cover the 2 year EU-mandated warranty:

If it just used the exchange rate plus tax, the prices would be 15" Air = £1199, 14" Pro = £1899.

There's probably some extra due warranty, but there are also other minor things that add costs (or might be more expensive outside US). Like developing and maintaining different language versions (both SW and packaging) and chargers, shipping, marketing etc. And, I think they also raise international prices when there's more uncertainty in the currency markets. They rarely change prices between updates, so whenever they see a currency risk, they take that in to account.
