In London, with prices of £3000 - £5000 per m2, you don't get a whole lot of customers with 3 bathrooms, hence very few inquiries for unvented.
Have had plenty of clients who reluctantly agreed on a big combi as they were used to cylinders and suspicious of combis, but 100% satisfaction rate so far.
Vast majority of property here still have 15mm incoming mains anyway, so unvented would not perform as well as possible, or incur lot of extra cost for upgrading mains.
