Comparable sails at comparable prices are frequently made on the other side of the World, either for or by some of the more prominent UK-based companies, frequently using materials shipped or even air-freighted from Europe.
The finished product may well be air-freighted back into the UK to meet delivery promises.

You might like to ask some other sailmakers where the sails they sell in this country are actually made.
You might be quite surprised!
